Re: Dinosaur a tecnical term; 3 specifically

Currently there technically is no such thing as a "revueltosaur".
Hopefully, this will be fixed sometime soon with an analysis...

The new paper mentioned in a previous post covers more taxa that we no
longer consider dinosaurian...

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.
