Prettige feite

1

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

2

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

3

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.21

4

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

5

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

6

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

?When did Joaquinraptor live?

It lived about 67 million years ago, near the very end of the age of dinosaurs. It was one of the last megaraptorids.36

?Did Joaquinraptor have big claws?

Yes, it had large, curved claws on its hands, like other megaraptorids. Its arms were long and strong.37

?Where was Joaquinraptor found?

It was found in central Patagonia, Argentina, in the Lago Colhué Huapi Formation. The fossils were collected from 2019 to 2023.36

Joaquinraptor was named by Lucio M. Ibiricu and colleagues in 2025. The skeleton was found in the Lago Colhué Huapi Formation in Chubut, Argentina, at a site called Valle Joaquin.21
Steeds omstrede
Scientists are not sure if the crocodile arm bone found with Joaquinraptor shows that it ate crocodiles, or if it got there by accident, such as being moved by water.1
