Dino Day: Giganotosaurus carolinii

Adapted from page 38:

The Giganotosaurus carolinii (“southern giant lizard of Rubén Carolini”)  lived during the late Upper Cretaceous (lower Cenomanian, ca. 100.5–93.9 Ma) in southwestern Gondwana (present-day Argentina). It was one of the largest predators of all time, as long as an urban bus, and weighing as much as an African elephant and a white rhinoceros together. The largest specimen is based on a very incomplete tooth that turns out to be 6.5% larger than that of the MUCPvCh1 type specimen. This individual would be as heavy as the largest specimen of Tyrannosaurus rex. Giganotosaurus was longer than Tyrannosaurus, but its body was less sturdy.

One of the largest theropods that left its imprints was a carcharodontosaurid (this group of dinosaur) from the early Upper Cretaceous of southwestern Gondwana (present day Brazil).
