Researchers have unearthed a new armored dinosaur in Utah, a new species of ankylosaur, known as Akainacephalus johnsoni. The catch? It lived on the lost continent known as Laramidia. A. johnsoni, a member of the ankylosaurid family, lived 76 million years ago in what is now southern Utah, but was once a land mass known as Laramidia, an island continent that split North America in two.
