Dale Russell Dinosaur Quotations

Most people feel that birds evolved from one kind of dinosaur. But our bad luck was to find the other kind of dinosaur, and unfortunately it has a bird-like heart too. So this means that bird-like hearts may be typical of highly evolved, late-in-the-era, dinosaurs -- they were evolving, they were changing.

This came as a shock because we didn't believe we'd find a heart. No one in his right mind could find a dinosaur heart from 66 million years ago.
