I also discovered the only complete Brontosaurus skull.

Stegosaurus was common only on well drained, dry soil.

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

One researcher just determined that African and Indian elephants make each other sick. When a new animal or plant is introduced to a habitat bad things happen. The biggest danger to native wildlife is foreign wildlife.

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.

Fossils have richer stories to tell - about the lub-dub of dinosaur life - than we have been willing to listen to.
