The Mongolian dinosaur was sold in New York for a million dollars.

In 1985, Reeve hosted the television documentary Dinosaur!

So I picked a Camarasaurus, because the Camarasaurus was the most abundant of the sauropods in North America.

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.

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

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

And you can see we got a guy from who's just a fanatic about dinosaurs to do the sculpting for us, down to the spoon shaped teeth and everything.

And so she looked into the bone of this T. rex, one of the thigh bones, and she actually found some very interesting structures in there.

And so, in addition to digging, I think we have some answers from the dinosaur record. I think these dinosaurs migrated we call it dispersal around the globe, with the slightest land bridge.

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

We gave samples to Mary Schweitzer, and she was actually able to determine that B rex was a female based on medullary tissue found on the inside of the bone.

And I and my colleagues cut into it, and we were able to determine, by looking at lines of arrested growth, some lines in it, that B rex had died at the age of 16.

The largest known carnivorous dinosaur was Spinosaurus , reaching a length of 16 to 18 meters (52 to 60 ft), and weighing in at 8150 kg ( lb).

Paleoecology Provenance and occurrence The bones of this primitive dinosaur were first discovered in 1991, by University of San Juan paleontologist Ricardo Martínez, during field work conducted by the University of Chicago and the University of San Juan.

I mean, is there anything that is not visualizing what can't be seen, in terms of discovering this dinosaur bone from a small piece of it that's out there, or seeing the distortion that we try to see as evolutionary distortion in one animal to another?

We did a little hand held device for teens that could hook up to the Internet, won Best Innovations at CES, but really I kind of slowed down and said, OK, I just ... After a while, I had this old tape of this dinosaur, and I gave it to this guy, and this other guy saw it, and then people started to want to do it.
