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

Traditional dinosaur theory is full of short circuits. Like the antiquated wiring in an old house, the details sputter and burn out when specific parts are tested.

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.

Stegosaurus was common only on well drained, dry soil.

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

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.

Birds evolved from a small raptor like theropod.
