Dr. Sereno, er, Billy guessed " Suchomimus",
a closely related species. That hardly makes him less intelligent than a ten
year old. Perhaps at the time he was remembering that the sucho fossil that he
found in Africa was a sub-adult, and full grown ones got much bigger. The sail
on the JP spinosaur sure didn't seem much bigger than Suchomimus. I think Dr.
Grant was wrong, and Billy hit the species correctly.
Hardly! As I said previously, the dorsal
neural spines of Suchomimus aren't that tall. They were half the height of
JP3's Spinosaurus and peaked over the hips. The JP Spinosaurus also has
fewer dentary teeth than Suchomimus, but is similar to Spinosaurus. In any
case, it is certainly easier to tell than distinguishing Gallimimus from
other ornithomimids externally, especially from so far away. Besides being
30% larger than most other ornithoimimids, only detailed examination of the head
or hands would be useful in singling out Gallimimus.
