This undated image provided by Ken Olson shows a drawing of the plesiosaur (marine reptile). A fossil found by an elk hunter in Montana nearly seven years ago has led to the discovery this new species of prehistoric sea creature. The new species of elasmosaur is detailed in an article published Thursday, April 13, in the Journal of Vertebrate Paleontology. The creature lived about 70 million years ago in the inland sea that flowed east of the Rocky Mountains from Canada to the Gulf of Mexico. (Ken Olson via AP)
