Gryposaurus monumentensis
(Pronunciation: GRIP-oh-SORE-us MAHN-you-men-TEN-siss)

Age: Late Cretaceous (~76 million years ago)

Length: 27 feet.

Geologic Formation: Kaiparowits Formation (middle unit)

Classification: Ornithischia – Ornithopoda – Hadrosauridae - Hadrosaurinae

Description: Hadrosaurids are often referred to as “duck-billed” dinosaurs because the front of their skull resembles a bill of a duck. Even the name Gryposaurus means “hooked beak lizard.” “Monumentensis” gives credit to Grand Staircase-Escalante National Monument in southern Utah where these animals were found. There are two types of hadrosaurs: those without crests, such as Gryposaurus monumentensis, and those with crests on top of their heads, called lambeosaurines. Gryposaurus monumentensis is unique compared with other species of Gryposaurus in that it the front part of the “beak” rises at a steeper angle. Three to four species of Gryposaurus have been found with a range from as far north as Alberta, Canada, to as far south as Texas, making Gryposaurus the genera with one of the largest geographical ranges. Gryposaurus was a very large duck-billed dinosaur – easily reaching the same size as Tyrannosaurus rex.
