Eoabelisaurus was an early meat-eating dinosaur from the Middle Jurassic. It lived in what is now Argentina, and it was one of the first members of the abelisaurid family, which later included big predators with tiny arms.1 4

izinto ezimnandi

Iinyani ezimnandi

Eoabelisaurus is the oldest known abelisaurid, living more than 40 million years before any other secure member of its group.1

Its skeleton is almost complete, including most of the skull, backbone, arms, legs, and hips.1

The arms of Eoabelisaurus were already starting to shrink, with the hand bones reduced compared to earlier relatives.1

It had a special elbow bone with a large bump, which may have helped with muscle attachment.1

Eoabelisaurus lived during the Middle Jurassic, about 184 to 174 million years ago.4

The fossils were found in rocks of the Cañadón Asfalto Formation in Argentina.4

Umfanekiso owenziwe yi-AI: Eoabelisaurus — Umfanekiso owenziwe yi-AI obonisa indlela Eoabelisaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Eoabelisaurus

?How big was Eoabelisaurus?

Eoabelisaurus was about 5.8 to 6.5 metres (19 to 21 feet) long and weighed around 730 to 800 kilograms (1,610 to 1,760 pounds).3 1

?What did Eoabelisaurus eat?

Eoabelisaurus was a meat-eater, a bipedal carnivore that hunted other animals.3 1

?Did Eoabelisaurus have small arms?

Yes, its arms were already starting to shrink. The hand bones were reduced and the fingers were short and robust, but the upper arm bone was not yet shortened.3 1

?When did Eoabelisaurus live?

Eoabelisaurus lived during the Middle Jurassic, about 179 to 178 million years ago.3 1

?Where was Eoabelisaurus found?

Its fossils were found in the Cañadón Asfalto Formation in Chubut, Argentina.3 1

?Is Eoabelisaurus a dinosaur?

Yes, Eoabelisaurus is a dinosaur. It is a theropod, which is a group of meat-eating dinosaurs.3 1

Inyaniso ngeentsomi

Intsomi: Some people think all abelisaurids had extremely tiny arms like Carnotaurus.

Inyaniso: Eoabelisaurus shows that early abelisaurids had longer arms with more fingers, and the reduction happened gradually over time.1

Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: Eoabelisaurus was named by Diego Pol and Oliver Rauhut in 2012. The skeleton was found at the Jugo Loco site in Argentina, and the species name 'mefi' honors the Museo Paleontológico Egidio Feruglio.1 4
Kusaxoxwa ngayo: Scientists debate whether Eoabelisaurus is a true abelisaurid or a slightly more primitive relative, because its skeleton shows a mix of features.1
