Me Again!How Fast Could Spinosaurus Run?
from Euoplacephulas, age 8, Alta, CA, USA; July 20, 2001

TOM: We honestly don't know how fast Spinosaurus could run, in terms of miles per hour. However, based on other spinosaur specimens, most paleontologists would accept that spinosaurs were probably slower than tyrannosaurs of the same body size, because tyrannosaurs (like Tyrannosaurus, Daspletosaurus, and Albertosaurus) have longer shin bones and narrow feet with shock-absorbing structures, while spinosaurs had shorter thicker shins and had broader feet.

Still, both spinosaurs and tyrannosaurs would probably be faster than elephants.
