Utah dinosaur unveiled to public, Study.
A dinosaur that was covered in bony armor from its spiky head to its clubbed tail is newest fossil addition to a Utah museum.
Scientists say the species of ankylosaur was a squat plant-eater that roamed southern Utah on four legs about 76 million years ago.
It was first discovered in 2008 in the Grand Staircase-Escalante National Monument’s rich dinosaur repository. The prepared and assembled fossil was unveiled Thursday at the Natural History Museum of Utah.
Researchers say they were expecting it to have smooth bony armor on its skull like other North American ankylosaurs, but were surprised to instead find evidence that it instead had spiky, bony armor on its head and snout like fossils found in Asia.
The Latin name for the species recognizes Randy Johnson, a museum volunteer who painstakingly freed the skull from rock and debris.
