Ceratopsidae, a family of thick-skulled, horned dinosaurs, including the well-known Triceratops, had teeth that functioned as shears, suggesting that they consumed particularly tough plants

In an article recently published in PLOS ONE, University of Calgary researcher, and friend of Dinosaur Island, Dr. Jordan Mallon, explains how dinosaur teeth give us insight into the varied diets of dinosaurs and how they co-exited for hundreds of millions of year in a complex ecosystem (the very theme of Dinosaur Island).
