趣味知識

Latirhinus means 'broad nose' in Latin, because its nasal bone was wide and flat.1

The first skeleton of Latirhinus was found in the 1980s by a team from UNAM in Mexico.1

This dinosaur lived about 83 to 72 million years ago, during the Campanian age of the Late Cretaceous.1 3

The type species is named Latirhinus uitstlani, where 'uitstlani' means 'southern' in the Náhuatl language.1

Some scientists think Latirhinus was a lambeosaurine, a group of duck-billed dinosaurs with hollow head crests.1

The holotype skeleton includes parts of the nose, backbone, arms, legs, and feet.1
