The world's largest dinosaur footprint has been identified

A new fossil was described, almost a meter wide, probably belonging to a lizard foot dinosaur.

According to an international research group on Peerj on July 24, the fossil of a dinosaur foot nearly one meter wide, excavated 20 years ago from mudstone in northeast Wyoming, is the largest fossil. discovered so far.

This new dinosaur is probably about 30m long.

The rest of this dinosaur skeleton has yet to be identified, but the size and shape of the foot bone indicates that it once belonged to a lizard foot dinosaur. These long ancient herbivores lived about 150 million years ago, in the late Jurassic period.

Study co-author David Burnham, a paleontologist from the University of Kansas Biodiversity Institute and Lawrence's Museum of Natural History, said: 'This animal is huge.' He estimated that the new dinosaur - nicknamed Bigfoot - might be about 30 meters long, or roughly the length of the blue whale.

In the late Jurassic period, lizard foot dinosaurs in North America lived in many areas that are now Colorado, Utah and southern Wyoming. Burnham said the excavations of Big Foot in northeast Wyoming showed that lizard-foot dinosaurs had lived here longer than previously thought.
