T. rex may still be the king of dinosaurs, but new fossils
suggest Spinosaurus had star power of its own and sported a dramatic
sail.
The newly discovered dino-era pterosaur looks to have been
built for scooping up fish -- a lot of them.
Prevalence of the dinosaur's skin in fossil record may have
more to do with texture, toughness than population density or habitat.
Discovery of three new Jurassic Era animals suggests that
early mammals, which resembled squirrels, first emerged 208 million
years ago.
