Re: Dinosaur a tecnical term; 3 specifically

Revueltosaurs were mostly tooth taxa identified as basal ornithischians 
until a better skeletal find of Revueltosaurus was made, showing it to 
actually be some type of herbivorous crocodilian and casting doubt on other 
presumed Triassic ornithischians known only from teeth.

Teratosaurus, as I recall, was thought to be a large Triassic theropod, but 
was later found to be a chimera of Plateosaurus and something else.

I really have no idea about Hallopus.
