It had a long, powerful tail and a set of coarsely serrated teeth for chewing tough vegetation. plateosaurus also had a large, curved claw on its thumb. Ceratopsians developed a method of slicing with teeth stacked on each other in batteries, and iguanodontians refined a method of grinding with tooth batteries, taken to its extreme in hadrosaurids. [46] Some sauropods also evolved tooth batteries, best exemplified by the rebbachisaurid Nigersaurus. [48] There were three general dinosaur faunas in the late Cretaceous.

The only exceptions are: Stephen O’Hanlon's dinosaurs diagrams are particularly noteworthy. And computer models can test the plausibility of putative mating positions. Fossilization is also discusssed at Evolution versus Creation, where we learn that "... there are no fossils being formed today on a large scale like they did many years ago ... when a fish dies, it doesn't sink to the bottom of the ocean and become a fossil, it merely decays and is eaten by other fish or animals.
