Austrocheirus was a meat-eating dinosaur that lived in what is now Argentina during the Late Cretaceous. It was about as long as a school bus and had hands that were not tiny like those of its relatives. Scientists are still debating exactly what kind of theropod it was.12

1

Austrocheirus is known only from a partial hand, a shin bone, foot bones, and some backbone pieces.1

2

Its name means 'southern hand' because its fossils were found in the southern part of South America.1

3

Unlike many other abelisauroids, Austrocheirus did not have tiny, shrunken forelimbs. Its hands were still full-sized.2

4

Some scientists think Austrocheirus might not be an abelisauroid at all. They say it could be a more general theropod whose exact family is unknown.1

5

The only known fossil of Austrocheirus was found on March 17, 2002, at a place called Hoyada Arroyo Seco in Argentina.2

6

A 2024 study suggested Austrocheirus might belong to a group called Berthasauridae, which are close relatives of abelisauroids.1

?How big was Austrocheirus?

Austrocheirus was a medium sized theropod, measuring about 5.5 to 6.5 metres (18 to 21 feet) long. That is roughly as long as a school bus.1

?Why is Austrocheirus called 'southern hand'?

Its name means 'southern hand' because its fossils were found in southern South America and only a partial hand was known at first.1

?Did Austrocheirus have small arms?

No. Unlike many of its abelisauroid relatives, Austrocheirus did not have tiny, shrunken forelimbs. Its hands were still full-sized.12

Austrocheirus was named and described in 2010 by paleontologists Martin Ezcurra, Federico Agnolin, and Fernando Novas. The species name isasii honors Marcelo Pablo Isasi, who found and prepared the fossil.12
E sa ntse e phehwa kgang
Scientists are not sure which group of theropods Austrocheirus belongs to. Some say it is an abelisauroid, others think it is a more primitive theropod, and a 2024 study placed it in a new group called Berthasauridae.1
