Stuff you should Know from House Stuff Works dot com. Hey,
(00:23):
and welcome to the podcast. I'm Josh Clark. There's Charles
w Chuck Bryant's Jerry, This Joson John, and this is
stuff you should know. Mega Loodon, Burgo Loodon, saxomaphone. Jerry,
How where's yours? Nice? Jerry? Yeah, she's trained, well so, Chuck. Yep,
(00:44):
you ever seen Mega Ladon? No, no, you haven't neither
ye NEI there's any human being because they're extinct, that's right. Um,
but they are pretty awesome. And when they were alive,
you would not have wanted to see one anyway mm
(01:07):
hmm well maybe from sure maybe until they learned to walk. Yeah,
and you would have been like, oh, I regret coming
to the shore today. Um. Caracodon megaladon, Yeah, I think
(01:27):
I don't know if it's a carcrodon. How's that couch adon?
Let's a carcrodon carchar I likedon right, that's the official name. Uh.
And it was a real thing. It's not made up. Um, No,
it is not the invention of a cryptozoologist or a
sci fi writer. No, it was a real thing. It
(01:49):
was a real thing. And giant, giant shark, I mean
so giant. It's it's I don't want to overuse the
word my bobbling, so I'm just gonna say incredible, you remarkable.
Should we go and just say the size of a
school bus? Yeah, I saw size of a greyhound bus.
It's about the same size. Well, I guess, yeah, one
(02:09):
smells a lot worse than the other. Which one and
the greyhound? The school bus just smells like fear and disappointment,
and the greyhound bus smells like all that plus days
and days of body odor and farts and cigarette butts.
Have you ever taken a long bus trip? That's a
(02:31):
one from Arizona to Atlanta. It's it's the worst. Yeah, no, one, No.
I think I might have talked about this. It didn't
dawn on me until like day two. I was like,
wait a minute, nobody is able to shower. We're all
just getting stinkier. We're all eating garbage food and farting
(02:51):
into our cloth seats. It was awful. How long did
the trip take. It feels like it was like three
days because you know, he's stop like every freaking two hours,
you know, because you got account for you know, however
many people on there, and it breaks down, didn't break down,
and you just had to stop a lot for breaks,
(03:13):
and we got stopped in Mississippi for a drug dog
to come on. Oh really, did anybody getting in trouble? No,
they just randomly stopped for the drop drug dog. And
this German shepherd jumped all over the seats and they
opened up the baggage underneath and he ran all over
the place. So I guess then he went home and
took a shower. Yeah, he was like man getting out
(03:34):
of there. I guess smuggling drugs on a on a
bus is Actually when I thought about it, was like,
what a great idea, Yeah, because it's apparently under the radar. Yeah,
and um, everybody else's smell is overpowering the smell of
the drugs. You'd think they probably were tons of drugs
on that bus and the dog was just like I
had ten pounds of cocaine and they didn't smell that
(03:56):
just kidding, So like you really needed to say just kidding.
You never no kids listen to this, Yeah, probably especially
this one. We want to say hello to all of
the sixth grade classes that are listening to this right now,
and we'd also like to say a special hello to
our new sponsor, Greyhound Bus Lines. Leave the driving to them,
(04:17):
so chuckers. Yes, um, where we are talking about the Megaladon,
the biggest shark that ever lived, and it may have
had from what I can understand, it makes sense too
if you stop and think about it. It may have
had the um most devastating as how I've seen it
put bite of any animal that ever lived in the
(04:37):
history of Earth. Yeah, I would say, I would say
that's accurate. It was bigger than t rex. T Rex
is very ferocious, had a very ferocious bite ergo ipso
fact though it was probably um more ferocious as bite
wise than t rex or anything else. Let's talk about
it all right before, like years ago, people were dumb
(05:02):
and they thought they found these fossils of these humongous
six inch teeth, like a tooth itself. It's like larger
than a hand, a human hand, like a largish human hand.
So so again to put this in perspective, because everybody
knows what great white teeth looked like about the size
of a shot glass. It's a great white tooth. Okay,
(05:24):
so about two inches. Um, these were six so three
times larger than a great white tooth. And t Rex
is right in the middle at something. Yeah, t Rex
is at about four inches. So we're talking a megaladon
tooth is fifteen centimeters in length, where great white sharks
is about five centimeters. And that's we're a single tooth.
(05:45):
I just went tooth, very very large, and I saw
that they actually go up to seven inches as far
as what they found. So four years ago people found
these fossils and they said, oh my god, it's a
petified dinosaur tongue, dragon tongue. Oh even better, Well, I
(06:06):
have dragon, snakes and dinosaurs down in my research. I
saw dragons only I believe in dragons four hundred years ago. Um.
And then in sixteen sixty seven, Danish anatomus named Nicholas
Stino said, these aren't tongues, their teeth. Don't be stupid, everybody, Yeah,
(06:29):
these are gigantic teeth, and everybody's like, don't be ridiculous.
They're they're dragon tongues. I'm wearing one around my neck
as we speak, and I use it in my potions,
along with eye of newt probably, so oh yeah, apparently
they did use it in medicine. You find something that big,
it's gotta have great powers short when you grind it
up and snored it. So they found these teeth over
(06:51):
the years, and these these fossils, uh, not only just
the teeth, but something called CenTra c E N t
R A H. And that is the uh it's not vertebrae,
but it's a part of the spine that doesn't deteriorate, right,
because here's the problem. A shark skeleton is made up
almost entirely of cartilage, So no matter how big it is,
(07:13):
over time that cartilage is going to break down and
return to the dust on the bottom of the sea
floor and you'll never know what was ever there. But
luckily those teeth in the center are made of harder
stuff and the teeth actually become fossilized. And there's another
one of my favorite episodes that just flies under the radar.
Fossil fossils was great, and that's an old one. So
(07:34):
you remember the fossilization processes where the the individual atoms
of this stuff are basically replaced by stone and the
thing literally turns to stone. So anything organic and it
is replaced by stone and it becomes fossilized in that sense.
So that's why something like a tooth could survive. It
(07:55):
becomes stone. And apparently the same thing goes with the center.
So taking megalodon teeth and mega look at then CenTra.
They started making calculations and measurements and figuring out like,
oh my god, this thing was enormous. Yeah, and we've
mentioned the t rex and dinosaurs a couple of times.
They weren't. If you're picturing in your head dinosaurs roaming
the earth and the megalodon swimming in the ocean fighting
(08:17):
one another. Yeah, they didn't overlap by about forty five
million years, so it wasn't even close. Uh. And of
course humans we haven't been around that long at all
in the Grand scheme, No Homo sapiens maybe a hundred
thousand years or so. Yeah, so obviously we were not
there during the time of the megalodon either. So our
opening bit about standing on the beach watching them is
(08:38):
was it was joked it's stanka bs just humor um.
So dinosaurs were around from two hundred million years ago,
just sixty five million years ago when the big asteroid hit,
and then Megalodon was from twenty million years ago to
about two million to one and a half million years ago.
It seems like, so yeah, absolutely no overlap whatsoever. And
(08:59):
I was just helping out a sixth grade class. Just
so you mentioned before, these scientists were left with quite
a task. It's not like finding of like a dinosaur
U dinosaur's bones and saying, well, we can put it together.
They didn't have a lot to go on with just
the center in the teeth. But they're much smarter than
we are, so they were able to do so. Yes,
(09:22):
And one of the things that the CenTra actually shows
two is growth rings. Right, so just like a tree,
sharks actually have a a signature of growth. I guess
you'd call it like a tree ring on their center
on these kind of vertebrae like structures. They get one
every year every season when it changes from I think
warm to cold, they get a little growth ring. And
(09:46):
so um, if you're an ichthyologist or a paleontologist or
a paleoich theologist specifically, Yeah, you could look at one
of these things and be like, oh, well, this this
megalodon lived to a hundred fifty years old because it's
a hundred and fifty rings. Yeah, and apparently, uh, wide
light rings means you grew faster as a megalodon and
(10:07):
narrow dark rings means you grew a little slower. So
they can look at these growth rates in the Age
of Death and just understand a little bit more about
the Great journey to extinction. So you too will understand
a little bit more about the Great Journey to extinction
right after these messages, so check. They found teeth, and
(10:48):
they found teeth actually all over the world. There's there's
a lot. It's an amazing amount of stuff that they
were able to glean from just finding some teeth in
some CenTra here um. And one of the things that
they figured out from the teeth is that, wow, we
found teeth all over the world, in Europe, in India
and Japan, in North America, South America, Africa, Australia. Basically
(11:11):
they've been found around every continent except for Antarctica. And
I would guess that if you could dig down through
the ice sheets around Antarctica, you would probably find some
megalodon teeth, yeah, because it was like very different a
million years ago down there. As far as right now, Yeah,
you'd like living in South Carolina. Nice coastal beach scene there.
(11:32):
Imagine the megalodon swimming around. That's exactly what happened in
two thousand nine. Um, some paleontologists from a a university
in Florida. I'll just say that they very generous of you.
They discovered some uh, some fossils. Uh. And these specifically
were interesting because they were all little baby megalodons. It
(11:56):
was a nursery. Yeah. And they discovered the same thing
off the coast of South Carolina, which if you know
how big something is when it dies, and you know
how big it is when it's born, just add them
together and divide by two and you have a pretty
good idea of what it's life was like. Uh. And
when they were little babies, they were just twenty long.
(12:16):
Yet that cute. They figured out did you say that
that nurser was found in Panama for those researchers, Uh, yeah,
And then then I think the other one is off
South Carolina. So they figured out from these teeth that Um,
the megalodon infant was as big as the normal size
great white shark adult, like a pretty big great white. Yeah,
(12:39):
that's like on the larger side. Yeah, that's amazing. Twenty
ft long are the babies. That's like um, baby huey basically,
but as a shark. So this means um, clearly, this
is the apex predator of its time. Um, and it can. Well,
it probably went everywhere because it could, but because nothing
(13:00):
threatened it, you could eat. It could eat whatever it
wanted to. And all things suggest that they had a
lot of whales, balleen whales. They found teeth marks on
whale bones. They even found teeth stuck in whale fossils.
Oh yeah, pretty exciting. No, what happened there? They were
in the middle of the meal when they got wiped
(13:21):
out or they lost a tooth and it went down
with the whale. Well it said teeth though, like maybe
they just lost it, but maybe it was like me
and it bit into the chicken bone started dropping teeth.
Was that what happened? The chicken bone? The second one, Yeah,
broke off at the Falcons game. It didn't hurt, right,
(13:42):
You told us about that. It was so weird. I
was like, well, my tooth just broken half okay, as
long as didn't as long as it didn't hurt. And
I went and sat back down to my seat and
was just passed out from the pain that suddenly swarmed. No,
there was no pain. The only pain was watching the
falcons this season. Uh so they weighed between fifty a
hundred tons and they could eat up to twenty hundred
(14:04):
pounds of food a day. I love this. I love
the comparison. I wasn't gonna do it. Okay, we won't
go ahead. The author said, that's five hundred more pounds
than the average American eats in a year. Just such
a dumb comparison. But it's also hilarious in every way.
(14:27):
I think good comparisons are one where it really hits
home like that doesn't. So the author should have been like,
that's fifty big max. Maybe that would have satisfied me
times fifty Uh terrible. Um did we say, chuck? How big?
(14:48):
The um? The mouth is based on these reconstructions. No,
they put you know, how you see the big giant
shark mouth. Sometimes it's from a real shark, and sometimes
they just put it together. In this case, they put
it together. Yeah, but the mouthful feature like real megalodon teeth.
But the jaws, the bone jaws or cartlet shaws are
obviously resin right. But you'll frequently see somebody standing in
(15:10):
one of these and they're just dwarfed by it. And
this is pretty accurate. Apparently they had it was reasonable
for a megalodon to have a seven foot diameter, which
is who knows how many meters to at least in
diameter the mouth, and so like I saw this one.
I think shark facts or something shark inside or some
(15:31):
site was basically like, actually, if megalodon were alive today,
you wouldn't have to worry about it because it would
be like you eating a cheese it and calling that
a meal. They wouldn't even bother with you. I would
not gamble that and swim around it, because even if
it just opened its mouth, you'd just go right in. Well,
we like cheese, it's exactly. Yeah. Uh, and if there's
(15:55):
a whole box of humans, that megalodon would probably eat
the whole thing, as a box of humans is called
the school bus. That's right full circle. Oh my gosh, Chuck,
So you talked a little earlier about the bite force. Um,
this is a good comparison, I think because it does
hit home. Um specialist, specialist. It's a weird thing to
(16:15):
say experts. Experts, she means cardiologists. Yeah, experts and researchers
say that a megala don's bite force was akin to
us eating a grape, them eating a whale skull. So
it could chomp through a whale skull the same as
we could much do a grape, even those of us
(16:36):
with fewer teeth. Yeah, and again it's not just the
bite wasn't so bad just because there the teeth are
so big and the the mouth was had such a
wide diameter. It was designed basically to yeah, to crush,
to disabled, to to disfigure in mame and pillage that
(16:57):
kind of stuff. That's right. So yeah, it would be
able to crush the skull very easily, and it did. Um.
As a matter of fact, the podcast art for this
episode has a megaladon eating a whale Like it's nothing. Man,
it's an artist's rendering. It's not a underwater photograph. But
(17:17):
it's pretty cool. Nonetheless, you know, it's also cool is
us taking a break? Oh yeah, so let's do that,
and we'll come back and we'll finish up on the
mighty micheladon Marldon stop. So how are these dudes? Remember
(17:52):
one and a half to two million years to twenty
million years is when they lived. I'm not sure how
long they lived, and I'm not sure that ich theology
just to paleoic theologists know yet. Well, I said, they
guess they became distinct about two million years ago. No,
I mean how long they lived in like the lifespans area,
it was pretty big. I don't know. Well, I mean
(18:15):
most large like whale, sharks and whales, they have long lives. Listen,
one hunts them. But they think they went extinct a
couple of million years ago during the Playo placed to
scene period. And um, we actually featured an article just
a few days ago about a new study on what
they think caused the extinction because they used to think
(18:36):
it had more to do with climate changes that they
couldn't keep up with. Yeah, but um, I believe the
same researchers who figured out the um or who found
that Panamanian nursery. Um. Also we're the ones who conducted
this study. Maybe not, but um, they they showed that
(18:56):
the global ocean temperatures rose, was and um declined during
this eighteen million year period where the megalodon was around,
and they're still Megalodon. Yeah, their populations apparently didn't change.
So they've basically said, no, we don't think it was
temperature climate change that did it. We think it was
a lack of diversity in the prey. Well, yeah, and
(19:19):
I guess what you were talking about, like eating a human,
Like you know, we'll say a human is six ft tall.
That's still pretty large. And if that's not a cheese it,
then you need to eat super large things and a
lot of them. And you better hope those large things
are successful at reproducing as well, because they go away,
you're in big trouble. And they basically think that's what happened.
(19:41):
The food sources became less diverse, and then smaller predators
evolved and started competing and we should probably faster and
better at hunting. And what happened by smaller they mean orcas. Yeah,
like that's that that was their smaller competition for the
same prey. Yeah, it's crazy. Yeah, and uh, who was it?
(20:03):
The Zurix Paleontological Paleontological Institute in Museum they examined two
hundred Megalodon records and came up with this new information,
and they flat out said, changing climactic conditions do not
appear to have had any influence. Yeah, they're like ocean hot,
ocean cold. We love it either way. Yeah, And I
(20:26):
mean if you if you're competing with an uh an
organism or species that is going after the same prey
but doesn't need as much as you to eat per day,
you're going to lose evolutionarily speaking, that it could very
easily be what it is. And because Megalodon, the recreations
of them look a lot like um great whites, a
(20:47):
lot of people are like, well, they're obviously great white ancestors.
Apparently not. Apparently they are more closely related to mako sharks, right, yeah,
mako sharks um and poor beagles sharks, although they would
share some sort of relation to um Great whites because
they would both be lamb uniforms. And the lamb niform
is a shark with two dorsal fins, five gill slits
(21:09):
in the mouth that extends back beyond the eyes, so
they can smile real wide after they eat a whole
boat full of people. So I was about to do
the Jaws line. Smile you son of a Um. We
should shout out Gordon Hubble. He's a megalodon expert who
uh he had his theory now I think it's cool.
(21:29):
He had his theory about the food source before. Uh,
it officially came out when everyone else was going and
now it was the climate. He actually theorized this beforehand.
So good on you, sir. Um. He's the same guy
who says no, no, no, there's no such thing as
this megalodon still right, Yeah, because we should do one
(21:50):
on cryptozoology as a whole. Um. There are people out
there that want to believe that somewhere in the depths
of the ocean and the deepest, darkest corners that we
have explored, that there are these giant beasts still living, right,
And actually they make great points. I mean, look at
the Ceila canth. We thought the silic canth went extinct,
and then it was caught off the coast of Africa
(22:11):
um in the thirties I think South Africa, UM, and
we realized, wow, this thing hasn't been extinct for a
couple of hundred million years. And then in the seventies
they found the megamouth shark, which is a here to
four unknown shark species that fed on plankton deep deep
deep in the ocean, and they caught one off of Hawaiian.
They're like, this is new. So crypto zoologist point to
(22:33):
these things and they say, how can you say that
there definitely is no um megalodons out there still? And
I think that same guy who you shouted out to says, well,
here's why, because the the megamouth shark um, which is
a plant eater, lives in this part of the ocean
(22:53):
where we just don't tread. We're just now developing the
technology to be able to go down there, so our
path wouldn't really cross. A megalodon would have the same
type of habitat that a regular shark has coastal regions, right,
so we definitely would have noticed a megalodon by now,
even if there was just one left in the whole world,
(23:14):
we probably would have encountered it by now because our
our habitats overlap a little bit. Then a sela can't.
Isn't the size of a school bus in fairness. Yeah,
So he kind of did a mic drop explanations and
um that they haven't found any megalodon teeth that are
not fossils, even though some people have claimed that, uh,
(23:36):
it's all bs. Yeah, can we say that safely? I
don't know. I think so. But that's not to say
that some people haven't made great hay out of this stuff,
including a guy named, um, what is that named Steve Alton.
He wrote a series of books called meg about a
megalodon that likes to battle people and dinosaurs and stuff
and it's great fun. And then of course there's Mega
(23:58):
Shark Versus Giant Octopus. Have you seen that? No? I
haven't either, but Debbie Gibson was in it apparently, Well
sign me up. And then there is a sequel to it,
um called Mega Shark Versus Crocosaurus. Yeah, Tiffany, isn't that actually?
Rkle Oh right, Julia White, good for him, and well,
(24:21):
I guess we got to talk about the elephant in
the room. Discovery Channel a couple of years ago, uh,
Discovery Channel, our our former bosses. They aired a show
um to kick off Shark Week about the megaladon that
was had the look of a documentary. Um, if you
(24:45):
didn't know any better, you would think it was real,
where they claimed the Megaladon was real, and that it
was um killing people off the coast of South Africa,
and it was this giant beast uh sixty seven ft long,
nickname a submarine and it's terrorizing humans and it was
called Megalodon. The monster shark lives. Um. They to put
(25:09):
it lightly, came under a little bit of fire from
the viewing public, most notably, well, not most notably, but
notably Will Wheaton. Uh, I don't know if we'll still
listen to our show, but at one point he did listening.
He was a friend of the show. Um. He wrote
a blog post which I'm so glad he did that.
He said a lot of things, but one of the
(25:30):
things he said was Discovery had a chance to get
its audience thinking about what the oceans were like when
the Megalodon roamed and hunted in them, and had a
chance to even show what could possibly happen if there
were something that large and predatoring the ocean today. But
Discovery Channel did not do that, and the cynical point
for ratings the network deliberately lied to its audience and
presented fiction as fact. They've betrayed its audience. UH. During
(25:53):
its biggest viewing week of the year and Discovery channels
that run by stupid people. This was not a mistake.
Someone may to deliberate choice to present a work of
fiction more suited for sci fi channel as truthful and factual.
That is disgusting. Whoever made that decision should be ashamed.
I was mad he got up on his uh hobby horse,
(26:13):
rightfully so, and called him out. Sure, not a hobby horse.
And here's the deal. After the show airs, they have
their uh what do you call it when you put
a disclaimer. Yeah, well they're sure they had a party
because it was huge in the ratings. But it said
none of the institutions or agencies that appear in the
(26:33):
film are affiliated with it in any way, nor have
approved its contents. Uh, those certain events and characters in
this film have been dramatized. Sightings of Submarine continue to
this day, which is total bs. Well, no, there are
a lot of people crackpots. To this day, there are
sightings or whatever, and Megalodon was a real shark. Legends
(26:56):
of giant shark persist all over the world. There's still
debate about what they may be. So basically people were
like Twitter lit up on fire. People went crazy and said,
Shark Week has jumped the shark officially, like you're airing
fiction is fact. And they came out a year after that.
Last year, I guess two years later, uh and the
(27:19):
new brand, the brand new chief Rich Ross Cross Rich
Ross uh and said, you know what, We're not gonna
do things like eating alive. Remember when they were gonna
have the snake eat the guy. Oh yeah, I forgot
about that. That was just a huge stain on their brand.
So we're not gonna do things like the Mermaids documentary
(27:40):
and the Megalodon documentary. What are they gonna do? He
said they were gonna try and get back to you know,
educational programming. So how have they done that yet? When
when did he say that? This is uh? And I
think he wanted to make a push to sort of
be the leader once again and smart educational programming and
not keep ratings boys. So we'll see nice. Um. Yeah.
(28:04):
The last thing I've got is if you love Megalodons
and you have a lot of money, you can buy
a Megalodon tooth for about bucks. I wondered about that
hundred Semolean boy, I would be worried that things fake. Yeah,
although I mean, like, if you look online, it'd be
tough to fake one. No one, all right, I mean
(28:27):
maybe to the discerning eye. But someone can make a
fake one and show me right now, and it's say
it looks real to me. Look at this? Maybe too,
Maybe the artists shouldn't have signed the bottom. Yeah, right,
that's it. I got nothing else megalodon. If you want
to know more about those, you can type that word
in the search bar. How stuff first dot com. And
(28:48):
since I said that, it's time for listener mate, I'm
gonna call this another one for the Equal pay Day
episode because we've got something a little wrong we want
to clear up. Um, whenever you guys touch on hey guys,
big fan, whenever you guys touch on sensitive topics, I'm
always a little worried. Is this going to be the
time they say something that makes me have to stop listening? No?
(29:11):
What you never do? Um? And this is from Ellen
and she says, uh, you guys mentioned that in the
US women are guaranteed twelve weeks of paid leave. I
have to take that one. I said that. Okay, I'm
assuming you're talking about the Family Medical Leave Act. I
wanted to point out a few strict qualifications, though that
don't apply to everyone. Uh. You must work for a
(29:33):
public agency, including state, local, and federal employers and local
education agencies like schools, or a private sector private sector
employer to employee fifty or more employees for at least
twenty work weeks in the current proceding calendar year, including
joint employers and successors covered employees. And I had a
nice exchange with some lady who this woman who had
(29:56):
to quit her job and she got pregnant because it
was under fifty employees. And she and I both conceded,
like we kind of get it. If you have a
really small business and you have eight employees and four
of them get pregnant, you're kind of screwed employees. Yeah,
And she was like, yeah, I get that, you know stuff.
And she said, you know, people should sort of think
(30:17):
about these things when they're going to get a job.
A woman, if they want to have a baby, maybe
go to a place that does have the f m
l A qualify qualification. UM. So she, you know, she
she got both sides of the issue. I so thought
that was nice. UM. Also an employements work for a
covered employer and have worked for that employee for at
(30:40):
least twelve months and have worked for at least twelve
d and fifty hours during that twelve months, and work
at a location where at least fifty employees are employed
at the location or within seventy five miles. So just
more specificity there. Thank you for that, Yeah, she said,
