Kritosaurus was a duck-billed dinosaur that lived in North America near the end of the Age of Dinosaurs. It had a big, flat beak like a duck and could walk on two legs or all fours. This plant-eater munched on tough plants with hundreds of teeth in its cheeks.1

makambo ya kitoko

Makambo ya kosepelisa

Kritosaurus means 'separated lizard' because the bones in its cheek were arranged in a special way.1

The first Kritosaurus fossil was found in 1904 by Barnum Brown in New Mexico, but the front of the skull was missing.1

Scientists once thought Kritosaurus had a Roman nose, but that was because the skull was broken and put back together wrong.1

Kritosaurus lived alongside other dinosaurs like Alamosaurus, Parasaurolophus, Pentaceratops, and Bistahieversor.1

Some scientists think Kritosaurus and Anasazisaurus might be the same dinosaur, but others disagree.1

Kritosaurus could reach about 9 metres (30 feet) long and weigh about 4 metric tons (4.4 short tons).1

?How big was Kritosaurus?

Kritosaurus reached about 9 metres (30 feet) long and weighed about 4 metric tons (4.4 short tons). Some partial remains from Mexico may have been around 11 metres (36 feet) long, but those are now considered a different dinosaur.1 2

?What did Kritosaurus eat?

Kritosaurus was a herbivore, eating plants with a broad beak and hundreds of teeth in its cheeks. It could feed from the ground up to about 4 metres (13 feet) high.1

?When did Kritosaurus live?

Kritosaurus lived during the Late Cretaceous, approximately 74.5 to 66 million years ago.1 2

?Where was Kritosaurus found?

Kritosaurus fossils were found in New Mexico, USA, in the De-na-zin Member of the Kirtland Formation. Some bones from Texas and Mexico were also referred to it, but those are now considered different genera.1

?Why is it called Kritosaurus?

Kritosaurus means 'separated lizard' because of the arrangement of its cheek bones. It's sometimes mistranslated as 'noble lizard' due to a mistaken idea about its nose.1

?Did Kritosaurus have a crest?

Yes, based on a skull originally referred to Anasazisaurus, Kritosaurus had a tab-like crest made of nasal bones that rose between and above its eyes and folded back under itself. This crest helped tell it apart from similar duck-billed dinosaurs.1

Mobuki masapo

Lisapo: Kritosaurus had a big bump on its nose like a Roman nose.

Solo: The original skull was broken and the nose area was reconstructed flat. Later scientists realized the real shape was probably arched like Gryposaurus.1
