When he was only 13 years old, Scott Persons was led to a sandstone slope right next to the Glenrock Paleon Museum, Wyoming.

Many years later, Persons -- now a doctoral student in paleontology -- returned to the site, studied it extensively along with colleagues and made a scientific report of the three dinosaur tracks carved in the stone by the eons. As it turns out, these findings belong to a tyrannosaur and are absolutely unique.
