AMAZING! think about it? Many dinosaurs may have been warm-blooded just like mammals or birds, potentially explaining their extraordinary success before their extinction.

Fox News seems a little late getting this one out to the public. As I recall, this was a hot discussion in 1993...when Jurassic Park came out.

Old news man, old news.
Main discussion on this is that they were so fast, which no cold blooded blooded animal would have been. Paleontologists are able to determine speed by distance of prints, such as 10 ft.= very fast, 2 ft= slow.

another interesting thing is that some dinosaurs that were terrestrial, had feathers. also others had hollow bones and bird like skeletons. but that is also old news.

Michael Crichton said this in Jurassic Park years ago. It was in his book because that is what paleontologists have been say in relation to numerous species like the Raptor.

They evolved over the period of 300 million years.

Dinosaurs were definitely not reptiles. Dinosaur legs point straight down like an elephant or rhino with the feet facing forward. Whereas a reptiles legs point east/west protruding from the sides of their bodies.

Dinosaurs migrated hemispherically. We know this through their migration trails and through the fact that we also find the same dinosaur bones in both the northern and southern hemispheres. Birds to this day, still migrate north and south just like the dinosaurs. They don't have to but instinct tells them too. It just so happens that birds are warm blooded!


Reptiles due to their cold bloodedness were forced to be (and still are for the greater part) equatorial.

Big Differences!

I think that Dinosaurs died out because they laid their eggs on the ground. Climate change (cold ground) combined with the rise of egg eaters (mammals) is what really killed the dinosaurs off. Not a comet!
