Datu dibertigarriak

1

Bonapartenykus is the largest known alvarezsauroid, measuring up to 3.3 metres (10.8 feet) long and weighing up to 72 kilograms (159 pounds).1

2

Its fossils were found with two incomplete eggs and many eggshell pieces, which were given their own scientific name, Arriagadoolithus.1

3

The eggs were found less than 20 centimetres (7.9 inches) away from the skeleton, so scientists think they may belong to Bonapartenykus.1

4

Bonapartenykus had a fused hip bone and a fused shoulder blade, which are unusual features that help scientists tell it apart from other dinosaurs.1

5

It lived between 72 and 66 million years ago, during the Maastrichtian age of the Late Cretaceous period.2

6

The name 'ultimus' means 'latest', because it was one of the youngest alvarezsauroids from South America.1

Mito-hauslea

Mitoa: Some people think Bonapartenykus was a bird because it had feathers and a beak-like snout.

Egia: Bonapartenykus was a dinosaur, not a bird. It belonged to a group called alvarezsauroids, which are close relatives of birds but still dinosaurs.1

Aurkikuntza
The first skeleton was found in Argentina and was described in 2009 as an unknown alvarezsaurid. In 2012, scientists Federico Agnolin, Jaime Powell, Fernando Novas, and Martin Kundrát named it Bonapartenykus ultimus.1
Oraindik eztabaidagai
Scientists are not sure if the eggs found with Bonapartenykus really belong to it, because they were not inside the body. They might belong to another animal.1
