I always liked the name _Stenonychosaurus_, myself. Why'd we get rid
of it, again?

Not to mention Hadrosauridae. (Titanosauridae, OTOH, doesn't seem to
be used much anymore.)

Well, _Suchosaurus_ is a pretty good name in terms of etymology, at least.
I don't see any problem with continuing to use _Baryonyx_,
_Troodontidae_, and _Stenonychosaurus_, myself. _Carcharodontosaurus_
has a different situation, though, as there is no newer name with
better type material -- it does seem like a good candidate for a
Incidentally, this raises an interesting code-related issue. It seems
that, whatever the status of _Suchosaurus_, Suchosauridae is still the
valid name for the corresponding family (which presumably would
include _Baryonyx_ and _Spinosaurus_) under the ICZN. But
_Spinosauridae_ has been given a phylogenetic definition. Of course,
the PhyloCode is not in effect yet, but suppose it were in effect and
_Spinosauridae_ were registered (e.g., with the definition
"Clade(_Baryonyx_ + _Spinosaurus_)") as a clade name. We'd have a
situation where Family Spinosauridae would be invalid under the ICZN,
but Clade _Spinosauridae_ would be valid under the PhyloCode.
