Rugops was a meat-eating dinosaur that lived in what is now Niger, Africa, about 95 million years ago. It had a wrinkled, bumpy face and a delicate skull, which scientists think means it was a scavenger rather than a fierce hunter.1 2

Rugops is known from only a partial skull, which is about 31.5 centimetres (12.4 inches) long.2

The top of its skull had many pits and bumps, which would have supported scales and a tough, armour-like skin on its snout.2

Rows of holes in the skull may mean Rugops had a crest or some kind of display structure on its head.1

Rugops lived alongside other huge predators like Carcharodontosaurus and Spinosaurus.2

The type specimen might have been a subadult, because its skull bones were not fully fused together.2

Rugops was one of the earliest abelisaurids, a group of horned, short-snouted theropods that lived in the southern continents.2

?How big was Rugops?

Scientists estimate Rugops was about 4.4 to 5.3 metres (14 to 17 feet) long and weighed around 410 kilograms (900 pounds). Some earlier estimates suggested it was up to 6 metres (20 feet) long and 750 kilograms (1,650 pounds).2

?What did Rugops eat?

Rugops was a carnivore, meaning it ate meat. Its delicate skull suggests it was a scavenger that fed on dead animals rather than a hunter that killed its own prey.1 3

?Where did Rugops live?

Rugops lived in what is now Niger, Africa, about 95 million years ago. Its fossils were found in the Echkar Formation, which was a river and lake environment.2

?Did Rugops have feathers?

Nobody knows for sure. Rugops is known only from a skull, and no feathers or feather impressions have been found with it. Its skull had pits and bumps that supported scales, not feathers.2

?Why is it called Rugops?

Rugops means 'wrinkle face' in Latin and Greek. It was named for the wrinkled, bumpy texture on its skull bones.2

?Was Rugops bigger than T. rex?

No, Rugops was much smaller. Rugops was about 4.4 to 5.3 metres (14 to 17 feet) long, while T. rex was over 12 metres (40 feet) long.2
