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...
Yes, true. Same for "silesaur".
This is the paper that got the ball rolling...
William G. Parker , Randall B. Irmis, Sterling J. Nesbitt , Jeffrey W. Martz
, and Lori S. Browne (2005). The Late Triassic pseudosuchian
_Revueltosaurus callenderi_ and its
implications for the diversity of early ornithischian dinosaurs. Proc. R.
Soc. B 272: 963-969.
_Revueltosaurus_ is some form of suchian/crurotarsan. Heckert (2005) argued
that a second species (_Reveueltosaurus hunti_) might be a bona fide
ornithischian, and erected the new genus _Krzyzanowskisaurus_. But Irmis et
al. (2006) put it back in _Revueltosaurus_, and referred osteoderms
(previously assigned to _Stagonolepis_) to _R. hunti_.

As Tom mentioned, _Teratosaurus suevicus_ is based on a maxilla that was
re-classified as a rauisuchian by Benton (1986). However, you're right in
saying that _Teratosaurus_ was a chimera. Huene later referred other
elements to this species, including detached teeth and associated
postcranial bones, because the teeth were similar to those of the
Walker (1964) suspected that the postcranial bones and maxilla/teeth did not
go together, and suggested that the former came from a _Plateosaurus_-like
dinosaur. Nevertheless, the idea of a radiation of Late Triassic-Early
Jurassic radiation of primitive carnosaurs called the 'Teratosauridae'
persisted for another twenty-or-so years.
Other 'teratosaurids' included _Cladeiodon_, _Zanclodon_, _Zatomus_,
_Aetonyx_, _Gryponyx_, _Palaeosaurus_, _Gresslyosaurus_, _Sinosaurus_ and
_Orosaurus_. Most 'teratosaurids' were based on detached teeth or jaws of
carnivorous archosaurs, or prosauropod bones, or both mixed together. Some
are genuine theropods (_Sinosaurus triassicus_, _Zanclodon cambrensis_).
