- This is my pet alligator, RJ.
What an absolutely amazing animal.
And alligators and crocodilians
have been around since the dinosaur era.
- Does that mean crocodilians are dinosaurs?
- Not really Mike, actually crocodilians
are not considered dinosaurs,
but they did actually live in the same era,
called the Mesozoic era of dinosaurs,
literally a hundred million years,
which brings me to my point.
Why are there alligators and crocodiles
and not dinosaurs?
- That's a good question Mr. Brian.
Why?
- Mike, I'll get to that in a minute.
My love of reptiles really started
with my love of dinosaurs.
I just have always been so fascinated
with dinosaurs, and an animal here like Elvis,
is like a little dinosaur,
or at least you think so.
But the truth is, there's a lot of differences
between reptiles and dinosaurs.
People used to think that dinosaurs
were really just reptiles of the past,
but the truth is, they were a lot different.
- So get to it Mr. Brian,
why are crocs here and dinos aren't?
- You see, about 60 million years ago,
there was a celestial event
where an asteroid actually hit off
of what now is the coast of Mexico.
That basically wiped out the dinosaurs, right?
And most people think that that celestial event,
when that meteor hit, this is what happened to the earth.
(continuous dramatic music)
But the truth is, is that that's not what happened.
Maybe for a few thousand miles from that hit
of the six kilometer wide asteroid,
probably wiped out everything within seconds,
but the rest of the earth didn't get wiped out immediately.
Like this, shrouding the earth in dust,
which basically made it dark and killed off
all of the plant life that basically took away
all the food for animals like these iguanas.
Of course iguanas weren't alive back then
but there certainly was iguanadons
and a lot of the dinosaurs were actually herbivores.
- So what you're telling me is,
dinosaurs ain't had no food so they died off?
- Now most dinosaurs, like this little monkey up here,
which is not really very little,
actually ate plants.
Which means if the earth was actually crusted with dust
and there was no light getting through
the plants would actually die
and this guy here wouldn't have survived.
- Guys, do you see that?
It's the elusive icecreamasaurus.
Let's try to tame him out with a little bit of food.
Here boy.
Now the icecreamasaurus' favorite treat is the cone.
Come on boy.
Wow, I've never had such a friendly experience
with the icecreamasaurus before.
(Mike laughing)
Come on, man.
- Dude, it's hard.
- Oh my God, wow!
(both laughing)
Wow!
He almost ate that whole thing in one bite.
Watch as he retreats back into his layer.
Wow, fascinating.
- What do you call a dinosaur accident?
- I don't know.
- Terranosaurus wreck.
- So dumb.
- Oh, we still haven't talked about
why crocodilians survived and dinosaurs didn't.
We know that because there wasn't plants
that herbivores actually died out.
But of course, because of the herbivores dying out,
so did a lot of the other dinosaurs,
but why did alligators and crocodile's actually survive?
It's really pretty simple.
What we've learned about dinosaurs
the last couple decades is the fact
that the majority of them,
believe it or not were warm blooded.
That's right, you think that they're reptile
and they're cold blooded or ectothermic.
The truth is most dinosaurs
were warm blooded more like birds, right?
And warm blooded animals need to use a lot of calories
in order to keep their body warm.
Whereas ectothermic or cold blooded animals
like crocodilians actually don't need all
of that caloric intake,
meaning they don't need to eat as often.
RJ has got some jaws on him.
And of course, that's one of the advantages
that crocodilians have, right?
It's the fact that they can only have
to eat once in a blue moon.
These guys can go up to a year without food.
Come on, RJ, up here.
There we go, bud.
There we go, buddy.
And the fact that they only have to eat once a year
because they're not putting chloric energy
into keeping their blood warm like we do.
It really is a huge advantage
to being able to survive long periods of times without food.
Come on, buddy.
And that certainly gives them the advantage
to survive a long period of time
with the harsh climate that the asteroid created.
- Titanoboa being the largest snake
in the world ever when the dinosaur existed,
being over 50 feet long.
- 50 of them.
- Amazing. Lucy here, is only about 20, 21 feet.
Something like that, but it's a pain in the butt.
- So imagine there's twice as much snake
and twice as many people.
- Yeah. She looks like she's in a real good mood today.
- I don't know. I think I'm good.
- I think the shoe made her mad.
- Yeah. It smells like garbage.
Oh, now you're dead.
- I'll let Mike do the heavy lifting
and then I'll hold her when she's out.
- We've got that cowboy.
- I don't want the dangerous end.
- Talk about the butt, not the face.
There we go.
- You guys are used to your pueblos.
- I don't got it.
I don't got it.
- Goodness. Oh, did he just grab his booty?
- Where did Jake come from?
- Scratching a booty.
- Could you imagine it this because it was twice as long?
- No.
- There's no way we could ever do that.
If it's twice the length
- He's moving today.
Now, yeah. Imagine twice the length and possibly.
- Three times the weight.
- Yeah.
- And more swift.
- Oh my God.
- Could you see here being pooped,
could you imagine Titanoboa.
- Could you imagine Titanoboa poo poo.
Could you imagine?
- I mean, the pee is like a gray lake.
He's there John Lenny.
- I mean just imagine that.
- Let's get it back.
- Quick, quick, put it back.
Put it back.
Holy macro.
Golly. Now that's a snake.
- Here we go, I'm done.
- Back in the tree she goes.
I need to get some water.
- So how long was the earth like that?
- It could have taken up to 10 years
for the dust to actually settle.
During that time, all the dinosaurs
that needed to eat almost daily
would certainly have perished.
Whereas the crocodilians with only needing
to eat maybe once a year,
means that they only had to maybe eat eight,
10, 12 meals over that decade long period
before the world started to come back around.
That's why crocodilians were able to survive,
when of course the dinosaurs wouldn't,
but they weren't actual alligators back then.
Just ancestors of alligators.
- Why do dinosaur museums only exhibit old bones?
- That's all is left of dinosaurs.
- They can't afford new ones.
- So today we're doing some renovations here at the Reptar.
We're taking our boy, Billy the silly Friley
and upgrading him into a larger enclosure.
- Oh yeah.
And you guys have seen Jurassic park
because who hasn't?
But these guys, the dilophosaurus with the big frills
and they run and they eat people.
So these guys that's where they came from.
So these guys have the frills.
The only difference is Billy doesn't eat people obviously.
- Yeah. And he doesn't spit venom, sadly.
- Who's gonna go into this big enclosure here.
Bigger upgrade, more space.
Billy, enjoy it my dude.
look at all of those.
- Chicken. It's so stupid.
- Look at all the branches and the plants
and the flowers so much.
- Fun. So much fun.
- It's exciting.
- So now we have an empty enclosure.
Let's go find the perfect animal to put in there.
- Bingo.
- This will work.
- Got him.
- Shove him in there, shove him in there.
I don't think he's gonna fit.
- I don't even think his beard fits.
- This is where things get really interesting guys.
And I just absolutely love it.
Of course back then the crocodilians
were actually Deinosuchus and Sarcosuchus.
Which were actually more like the modern day gharial
and the modern day alligator.
Deinosuchus was more like an alligator,
but could get like 40 foot long.
Of course Sarcosuchus was more like a gharial
with a thinner snout
but again could get 40 sometimes even 50 foot long.
How amazing is that?
And that's where the modern day crocodilians
actually evolve from.
was those two Deinosuchus and SarcoSuchus.
Could you imagine a gigantic crocodile
that's 40 or 50 foot long that could easily two,
three, four people in one sitting.
Keeping in mind that they actually ate dinosaurs.
That was their primary food.
The Deinosuchus probably hunted animals.
- Oh, the icecreamasaurus.
- Maybe even like T-Rex, which is absolutely incredible.
And then the Sarcosuchus of course was more aquatic.
So they were hunting aquatic dinosaurs,
aquatic prehistoric fish.
I mean, how amazing is that?
- I eat dinosaur chicken nuggets.
- I don't know Mike.
That one's pretty moving.
Let's try to find some a little more tame buddy.
- Maybe. Yeah.
- I don't want no Python Maria.
- That won't bite
- Good Job, Maria.
- All right, so we were thinking maybe
the tanzinianin, oh Sanzinia
- Sanzinia.
- I thought it was a T, my bad.
- They're from Tanzania.
- I think they're from Tanzania
I don't know.
We thought about putting these beautiful boas over there.
Well, I think we're gonna keep them over here anyways
for another bit just to make sure
they get a little bit more established.
- Established.
- Not those guys.
This is the one that we're gonna bring.
For all you reptile lovers,
and if you don't know what this is, shame on you.
- Shame him.
- This is our diamond python.
- Diamond.
- Beautiful.
- This is our male diamond python.
We're gonna bring him over,
get him set up in that nice cage for now.
Obviously he's gonna outgrow.
That's what the expansion is for, you know?
The female's gonna stay here,
get big fat, then we can breed.
Let's get the male over next door.
It could be so cute.
- So cute.
- What did the dinosaur call her blouse store?
- What?
- Triceratops
- Oh my God.
- My obsession with dinosaur,
spills over to my obsession with reptiles.
There's no doubt about it.
And I've often thought what would happen
if I was in the dinosaur era
and I found a clutch of eggs like this?
This of course is a pastel female,
and she's bred to, this Calico pin yellow belly.
And she certainly has a beautiful clutch of eggs right here.
I'm just gonna go ahead
and remove these guys without getting bitten by mama.
Mama's like protecting your eggs.
And I wonder about that.
Wonder if dinosaur mama's protected their clutches.
Wouldn't that be amazing?
To find a clutch and then having a T-Rex
that's actually protecting it.
It could be really wild and I'd imagine they would.
It's really cool.
We've got two, four, six, seven beautiful eggs.
I wish I could find some dinosaur eggs.
- Good how cool this thing is.
- Dude you're a dense on these guys too.
- I don't even see that.
I'm not gonna, I don't see it, but just look at the beauty.
- See you a little bit.
- Yeah. I mean a touch, I suppose.
- Not like the boas.
- No.
- But still beautiful snakes.
Like I said, if you don't know, do some research man.
what do you guys think?
We thought about naming him Jared,
like the diamond store?
- No, you subway.
You can't name him Jared.
- Jared for the male and Kate for the female.
- God, it's just so terrible.
I just...
- I know but it's good though.
- No, it's really just the worst.
- What some cool?
Like diamond or rich name?
What do you name Bruno Mars.
Did you hear that song, "24K"?
- Maybe you could name him Bruno.
- Bruno.
- And it's like a double entangle because of the Disney.
- We don't talk about Bruno.
- I like Bruno.
- Bruno.
- Let's know in the comments if you like Bruno.
- But then we need a girl's name.
Lots of names
- Sumo
- Sumo. Oh Sumo and Suma.
- And that's the reason why the modern day alligators
and crocodile's are still here and their counterparts,
Sarcosuchus and Deinosuchus are long gone.
Speaking of long gone, I'm outta here.
