Pachycephalosaurus wyomingensis "gigas" (*) (CB-Topps)

Disambiguation LinksPachycephalosaurus wyomingensis “gigas” (IDW-JPR)

The “thickhead reptile” was described by Gilmore in 1931. Pachycephalosaurus lived during the Late Cretaceous Period about 67 to 65.5 million years ago. It was about 4 meters (13 ft) in length, 1 and half meters (5 ft) in height and 800 pounds (365 kilos) in weight. Pachycephalosaurus in the comic appears to be larger than the real animal.
