Pachyrhinosaurus sp. (S/F)

Pachyrhinosaurus and its infant in the Jurassic World: The Exhibition show

Pachyrhinosaurus was a centrosaurine ceratopsian dinosaur that lived during the Late Cretaceous in what is now North America. First discovered in Alberta, Canada by Charles M. Sternberg in 1946, it was later described in 1950. Pachyrhinosaurus was relatively unheard of until the 1980s when more specimens became available for study. Three species have been named, P. lakustaiP. canadensis, and P. perotorum, the last of which was discovered in Alaska. Pachyrhinosaurus didn’t have actual skull horns, but rather large, flattened bosses; one over the nose, and a smaller one above the eyes. Two horns grew from their frills in a sort of curve. The largest specimens of Pachyrhinosaurus are 8 meters long, and weighed around 4 tonnes.

According to the Dinosaur Protection Group viral marketing website, InGen had been working on the DNA of Pachyrhinosaurus before Isla Sorna was abandoned and had obtained only 8% of the genome. After being bought by Masrani Global they were able to complete the genome and clone the animal, but whether it was living on display in the Jurassic World theme park is unknown. Mattel made a toy of the Pachyrhinosaurus, although named Sinoceratops due to a late species change during the post-production of the movie after the toy had already been mass-produced. The dinosaur also featured in the Jurassic World: The Exhibition, where guests would witness an adult Pachyrhinosaurus with her infant.
