Oldest horned dinosaur in North America named

A new dinosaur was named this week in a paper published by the journal, PLOS One. It's called Aquilops americanus, or American eagle face, for its beak and bird-like appearance.

It's the oldest horned dinosaur found in North America and was smaller than the thundering creatures we've come to associate with dinosaurs - closer to the size of a rabbit or large crow.

The Aquilops skull was discovered in Montana in 1997 and dates from the early Cretaceous period. It is quite dissimilar from later-era horned dinosaurs, or ceratopsians, like triceratops. This shows that it likely came to North America from Asia on a land bridge.

Andrew Farke, lead author of the study and paleontologist at the Raymond M. Alf Museum in Claremont joins the show with more.
