You'd have a big dinosaur and a littler dinosaur.

Now if you want dinosaur DNA, I say go to the dinosaur.

We're not going to be able to make a dinosaur based on a dinosaur.

I wanted to be a paleontologist, a dinosaur paleontologist, and I wanted to have a pet dinosaur.

228 million years old, we found what really is the most primitive dinosaur that's the Ur dinosaur.

But it's not dinosaur DNA.

The chicken is a dinosaur.

It's a giant duck bill dinosaur.

Dinosaur used camouflage to evade its enemies

So if you ever fantasize about going back in time and seeing what a dinosaur looked like, that's what a dinosaur looks like.

'Strong predation on a massive, heavily armored dinosaur illustrates just how dangerous the dinosaur predators of the Cretaceous must have been,' said Brown.

Jack Horner Building a dinosaur from a chicken

This is actually what most dinosaur research looks like.

The report in the journal Current Biology described it as 'the best preserved armored dinosaur ever found, and one of the best dinosaur specimens in the world.'

You know, how why would a kid want a dinosaur?

And so here was the first soft tissue from a dinosaur.

They're not going to do something like the dinosaur killer did.

So I said, OK, let's try to do this dinosaur project.

And if you cut into an older dinosaur, it's very massive.

Coming face to face with a dinosaur was a funny experience.

Now mostly tails limit maneuverability, like this human inside this dinosaur suit.

And so we're making a better picture of what a dinosaur looks like.

So we don't have to make a dinosaur because we already have them.

Now, to find dinosaurs, you hike around in horrible conditions looking for a dinosaur.

And this is a you know, the purple dinosaur with kind of bloat wear.

That's where dinosaur origins is to be found at the bottom of the cliff.

We are extremely dinosaur like, and unusual in our two legged approach to life.

So if you cut open a little dinosaur, it's very spongy inside like A.

So we have discovered that dinosaur DNA, and all DNA, just breaks down too fast.

You can call it a dinosaur, but look at the velociraptor the velociraptor is cool.

And sites like it are kind of going the way of the dinosaur right now.

It's not as gripping as dinosaur sex, so we're not going to go into it further.

They started with Cinematch, and they've tried a bunch of others there's Dinosaur Planet there's Gravity.

Back in 1993 when the movie came out, we actually had a grant from the National Science Foundation to attempt to extract DNA from a dinosaur, and we chose the dinosaur on the left, a Tyrannosaurus rex, which was a very nice specimen.

If you look at dinosaur hands, a velociraptor has that cool looking hand with the claws on it.

The theme of this story is building a dinosaur, and so we come to that part of Jurassic Park.

So again, real easy to say that Tyrannosaurus ontogeny included Nanotyrannus, and therefore we can take out another dinosaur.

The crazy idea is we're going to try to clone a dinosaur as much as we can with today's technology.

Dinosaur evolution proceeded at a stately pace, an order of magnitude slower on any way you want to measure it.

So here's a dinosaur that has spikes sticking out of its head, no dome and gnarly stuff on its nose.

It's not a dinosaur it's a whale, animals as big as office buildings still swimming around out there in our ocean.

We're working on also simpler technology, not that complex, with younger people and also older people, like this dinosaur is from Mexico.

Let me note that we have not had a giant impact like the dinosaur killer for 65 million years. They're very rare.

Now, I tried to suture together a dinosaur evolutionary history so that we can try to understand some basic patterns of evolution.

But cutting into the bones of a dinosaur is hard to do, as you can imagine, because in museums bones are precious.
