Titanoceratops

What it was like

Titanoceratops was a very large horned dinosaur, with a huge skull, a long frill and horns over its eyes. It belonged to the same branch of horned dinosaurs as Triceratops and Torosaurus.

Its world

It lived in the Late Cretaceous in what is now the southwestern United States, where it would have been one of the biggest plant eaters of its day.

How it was found

Longrich named Titanoceratops in 2011 from a big skull and skeleton that had long been filed under Pentaceratops. He argued that details of the skull tied it to Triceratops instead. Other scientists disagree and think the fossil is simply a large, old Pentaceratops, so its status is still debated.
