Dinosaurus is not a late Cretaceous theropod (great Scott--yet another error
in that book) but a large Late Triassic prosauropod presently referred to the
genus Plateosaurus as Plateosaurus ingens. It started out as Dinosaurus
gresslyi Ruetimeyer, 1856, but this name was changed to Gresslyosaurus ingens
by Ruetimeyer in 1857 when he learned that Dinosaurus was preoccupied by the
therapsid genus (should have called it Gresslyosaurus gresslyi, by the way,
preserving the orginal species epithet). Other species have been synonmized
with this species as well.
