Dr. Tom Holtz and Dr. Michael K. Brett-Surman
answer dinosaur questions for the readers of ZoomDinosaurs.com
:



Me again. Is the Paralititan dinosaur a new find? I read that its humerus is 14% longer than those of other Cretaceous sauropods. And is Argentinosaurus a possible relative? Why is this suggested?
from Chelsea, age 14, ?, ?, USA; July 19, 2001

TOM: Yes, Paralititan was just discovered. It is very large, although it seems to be smaller than Argentinosaurus. (The humerus of Argentinosaurus isn't known yet, so we can't compare those measurements). Argentinosaurus is very likely a close relative, based on the detailed structures of those bones known in both species.
