New dinosaurs in a long-forgotten world and you've never heard of it?  Don't be alarmed, the "lost continent" of Laramidia was formed when a shallow sea flooded the central region of North America, isolating the eastern and western portions of the continent for millions of years during the Late Cretaceous Period.  It was a swampy, subtropical setting - in Utah.

But it wasn't the only thing lost.   Two new species of horned dinosaurs have been found in Grand Staircase-Escalante National Monument in southern Utah.
