new theory on dinosaur domination

Huge Croc Extinction Led to Dinosaur Domination
Approximately 201 million years ago, the Triassic-Jurassic mass extinction killed off a slew of huge predators, including hefty beasts that looked like crocodiles and enormous armadillos, according to new research that also suggests dinosaurs benefitted from the losses.Some of the prehistoric predators -- animals known collectively as the early pseudosuchians -- likely preyed on certain dinosaurs, which later evolved some of impressive characteristics of the ancient pseudosuchians. Those included features like sturdy body armor and strong tails for whacking enemies.
