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

makambo ya kitoko

Makambo ya kosepelisa

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

Mituna oyo batunaka mingi na ntina na Austrocheirus

?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

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
