Re: extinction



Two were bigger than the end-Cretaceous extinction (which ended the non-avian dinosaurs):

1. the biggest is the end-Permian
2. second biggest is end-Triassic (which wiped out most of the crurotarsan archosaurs, enabling the dinos to diversify)


>>I dont mean that which kill dinosaurs, i mean that extinction what was biger than dinosaurs.
was it in late triassic?<<
