Cross Breeds

What animals disappeared or became extinct specifically during the Triassic period?

I need it only in the Triassic period... and not just dinosaurs i need as many animals, and they need to be specific. Like I actually need the breed, not just a group like amphibians.

1. The mamal-like reptiles (archosaurs) are the most famous. Their extinsion lead to the rise of Dinosaurs, there were not many Dinosaurs around a the time and the ones alive did not suffer losses. Try the link below, it gives a list. http://www.ldeo.columbia.edu/ ~polsen/nbcp/trj.html
