In the subpages of this page, you will find information about animals and prehistoric events that do not follow the same structure as the main animal sections. These are more like articles, sort of. The subpages are:
What was The Great Dying?
The Real Tyrannosaurus rex
The Cretaceous Mass Extinction
Evolution of Mammals
Dinosaurs After The Cretaceous
Scientific mess-ups
Dinosaurs Aren't Reptiles?
You should probably read them in chronological order, as listed above.
