SALT LAKE CITY (AP) -- Paleontologists say they've found fossils from a previously undiscovered species of dinosaur hidden in slabs of Utah sandstone that were so hard explosives had to be used to free the remains.
The bones found at Dinosaur National Monument are a type of sauropod, which were long-necked plant-eaters that were the largest animal ever to roam land.
The new species is called Abydosaurus mcintoshi.
Monument paleontologist Dan Chure says the fossils offer fresh insights into lives of dinosaurs some 105 million years ago, including the evolution of sauropod teeth.
Details of the finds were made public Tuesday and are being published in a peer-reviewed science journal.
