Dinosaur find in state called unprecedentedJun 4, 2013 The Associated Press
SIOUX FALLS, S.D. -- The recent discovery of three Triceratops fossils in Wyoming could include the most complete skeleton of the three-horned dinosaur to date.
Until the discovery last month near Newcastle just west of South Dakota's Black Hills, only two relatively complete Triceratops skeletons had ever been found, the Sioux Falls Argus Leader reported.
The plant-eating dinosaurs that lived more than 65 million years ago often were meals for predators, which left behind only their skulls for dinosaur hunters to find.
The South Dakota-based Black Hills Institute of Geological Research and the Naturalis Biodiversity Center from the Netherlands are excavating the remains of the Triceratops and the left foot and leg of a Tyrannosaurus rex.
Black Hills Institute president Pete Larson said he was excited when he first saw the T. rex foot, but he soon realized the potential presented by the Triceratops bones.
