Ebyewuunyisa

Joaquinraptor is a member of a group called Megaraptoridae, which are known for their large claws on the first and second fingers.1

The only known skeleton of Joaquinraptor includes parts of the skull, backbone, shoulder, arm, and leg bones.1

This dinosaur lived during the Maastrichtian stage, about 72 to 66 million years ago, right up to the time when the non-bird dinosaurs went extinct.2 1

Joaquinraptor was one of the last surviving megaraptorid dinosaurs, and it may have been the top predator in its ecosystem in central and southern Patagonia.1

The fossil of Joaquinraptor was found with a crocodile arm bone between its lower jaws, and some of its teeth touched that bone. This might mean it was eating a crocodile.1

Joaquinraptor was named in 2025 by a team of scientists led by Lucio M. Ibiricu. The name honors the first author's son Joaquin and the fossil site called Valle Joaquin.1
