Tyrannosaur Footprint

Caption

Just outside the tiny town of Glenrock, Wyoming the footprints of a 66-million-year-old monster are cemented in stone. This fossil trackway was brought to light with the help of University of Alberta paleontologist Scott Persons, who first viewed the tracks as a 13-year-old while visiting the Glenrock Paleon Museum.
