Dr. Clint Boyd of the South Dakota School of Mines and Technology and his team have discovered a new species of herbivorous dinosaur.  Last week, they published the first fossil evidence of prehistoric crocodyliforms feeding on small dinosaurs.  The evidence was found in what is now known as the Grand Staircase Escalante National Monument in southern Utah and dates back to the late Cretaceous period.  Boyd talked about the find and research on Wednesday's Dakota Midday.
