"AJ," New Species Of Allosaurus, Found At Dinosaur National Monument

Despite the imagery of dental picks, small handheld whisk brooms or paint brushes, and chisels, sometimes paleontologists need something bigger to get a fossil out of the rock. Like explosives and helicopters. “One of the things that we do when we have a skeleton that’s all articulated, or all the bones are all fitting togerher, we like to keep those bones togerher in that way so we can preserve the context and how they fit together," explained Dr. Mark Loewen, a University of Utah paleontologist. "This was a very, very large block. In fact, it was the largest dinosaur block of bones that had ever been taken out in the state of Utah up to that point."

Fearsome meat-eating dinosaur the size of a bus with serrated teeth and razor sharp claws is officially recognised as a new species 30 years after discovery

A savage meat-eating dinosaur the size of a bus that slashed its prey to death has been recognised as a new species 30 years after its remains were dug up in Utah. Scientists uncovered remains of the meat-eating Allosaurus jimmadseni – which roamed the North American flood plains 155 million years ago – back in 1990. A study of the bones of A. jimmadseni has been published in PeerJ after seven painstaking years spent preparing the bones for analysis.
