Ebyewuunyisa

Arrhinoceratops lived a few million years before its famous relative Triceratops.1

The name 'Arrhinoceratops' means 'no nose-horn face', but scientists later realized it actually did have a nose horn, just a short one.1

Only one complete skull of Arrhinoceratops has been found, so scientists do not know much about the rest of its body.1 2

Its skull had a broad, square frill with two oval openings and a scalloped rear edge.1

The frill of Arrhinoceratops was decorated with about nine bony bumps called osteoderms along the sides.1

Arrhinoceratops lived in a wet coastal environment with warm summers and cool winters, and may have been hunted by the tyrannosaur Albertosaurus.1

The first Arrhinoceratops skull was found by a University of Toronto expedition in 1923 along the Red Deer River in Alberta.1

Ebibuuzo ebisinga okubuuzibwa ku Arrhinoceratops

?How big was Arrhinoceratops?

Estimates vary. Some popular science books estimate it was about 6 metres (20 ft) long, while Gregory S. Paul estimated 4.5 metres (15 ft) and 1.3 tonnes (2,900 lb).1 2

?What did Arrhinoceratops eat?

Arrhinoceratops was a herbivore. It likely ate ferns, cycads and conifers, using its sharp beak to bite off leaves or needles.1

?When did Arrhinoceratops live?

It lived during the Late Cretaceous, about 72 to 67 million years ago, a few million years before Triceratops.2 1

?Where was Arrhinoceratops found?

Its remains have been found in Canada, specifically along the Red Deer River in Alberta.1 2

?Did Arrhinoceratops have a nose horn?

Yes, it did have a nose horn, but it was short and blunt. The name 'no nose-horn face' was based on a misunderstanding.1

?Was Arrhinoceratops a dinosaur?

Yes, Arrhinoceratops was a ceratopsian dinosaur, a type of horned, herbivorous dinosaur.1 2
