Baby Allosaurus Dinosaur Track – San Rafael Swell – Utah
The Allosaurus, who’s name means different reptile, is a large carnosaurian theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic epoch. The allosaurus was a large bipedal predator, the largest known example of which was more than 32 feet long. The majority of allosaursus fossils have come from the Morrison Formation, which covers a large geographic area in several western states, including Utah, New Mexico, Wyoming, Colorado and Montana. The first known example of the dinosaur was described by paleontologist Othniel Charles Marsh, in 1877.
The photographed dinosaur track comes from the Grand Rafael Swell in central Utah, near the town of Price.
