Often extinctions in the ocean occur at the same time as those on land. Then again, the ice age extinctions lost many big animals, but not many sea faring ones.

To me it seems that the warm blooded dinosaurs replaced advanced mammal ancestors that were warm blooded, also.

As an undergraduate I held many small jobs as an illustrator.

Also, while I was at Yale, I had a job teaching kids at the museum.

Inveterate creationists, then or now, never allow their faith to fall victim to facts.

I also got a chance to go to the American Museum in New York, which helped my interest.

In 1941 Richard Owen said that the dinosaurs were almost hot blooded.
