RE: OLD ORNITHOMIMOSAURS

and a tooth was associated with the _Gojirasaurus_
specimen, but it's pounds to peanuts that the tooth
may belong to another animal (like the critter that
was munching on the carcass, a la Teratosauridae.)>

  Carpenter (1997) and in-person on the list, has
reminded us that the holotype of *Gojirasaurus* has
teeth, which are distinctly coelophysoid in form and
are large enough to pertain to the holotype (a larger
form than *Coelophysis* and different from
*Dilophosaurus*) so thus ruling out the edentulous
*Shuvosaurus* (including associated premax without
teeth found near Gojira) as the skull for this form;
edentulous rauisuchians are known, so it is not too
far to see *Shuvosaurus* as being convergent or
applicable to the rauisuchid form.

  Gosh, another "dinosaur?" might end up as a
rauisuchid. I can see a wonderful perspective paper on
"Rauisuchians and Convergent Evolution with Dinosaurs"....

  Dinosaurs are horrible, terrible creatures! Even the
  fluffy ones, the snuggle-up-at-night-with ones. You think
  they're fun and sweet, but watch out for that stray tail
  spike! Down, gaston, down, boy! No, not on top of Momma!
