Abelisaurus was a big meat-eating dinosaur that lived in Argentina near the end of the Age of Dinosaurs. It had a short, deep skull with lots of holes and bumps on its nose. Only its skull has been found, but scientists think it was a fierce predator.1 5

Datu dibertigarriak

Abelisaurus had a very large opening in its skull called the antorbital fenestra, which was proportionally bigger than in Tyrannosaurus.1

The skull of Abelisaurus is 85 centimetres (about 2.8 feet) long.1

Its nose bones were rough and bumpy, with small sharp points.1

Abelisaurus lived during the Maastrichtian age, between about 72 and 66 million years ago.5

The family Abelisauridae was named after Abelisaurus, and its relatives lived mainly in the southern continents.1

The only known fossil of Abelisaurus is a partial skull, missing the right side of the jaw and most of the palate.1

zure galderak

Abelisaurus: gehien egindako galderak

?How big was Abelisaurus?

Estimates vary a lot because only a skull is known. In 2016, scientists estimated about 7.4 metres (24 ft) long, but earlier guesses ranged up to 11 metres (36 ft). Its weight was estimated at about 1.65 to 3 tonnes.2 4

?What did Abelisaurus eat?

Abelisaurus was a meat-eater, with sharp teeth for tearing flesh. It may have hunted or scavenged, and some scientists think it hunted long-necked titanosaurs.2 4

?Did Abelisaurus have feathers?

Nobody knows for sure. The only fossil is a skull, and no feather impressions were found. Some related dinosaurs had feathers, but Abelisaurus probably had scaly skin, though we can't be certain.2

?Was Abelisaurus bigger than T. rex?

No, Abelisaurus was much smaller. T. rex could be over 12 metres (40 ft) long, while Abelisaurus was only about 7 to 11 metres (23 to 36 ft) long, and much lighter.2

?Why did Abelisaurus have a bumpy nose?

The bumps and ridges on its snout might have supported a crest made of keratin, which wouldn't fossilize. This could have been for display, like attracting mates or scaring rivals.2 4

?When did Abelisaurus live?

Abelisaurus lived during the Late Cretaceous, about 83 to 66 million years ago, in what is now Argentina.2 5

Aurkikuntza: Abelisaurus was named by Argentine paleontologist José Bonaparte in 1984. The skull was found in the Allen Formation near Lago Pellegrini in Río Negro, Argentina. The name honors Roberto Abel, the director of the museum where the fossil is kept.1 5
Oraindik eztabaidagai: Because only a skull has been found, scientists are not sure how big Abelisaurus was or exactly what its body looked like.1
