Gravitholus albertae (C/N)

Gravitholus albertae (heavy dome) was discovered in 1979 by W. P. Wall and Peter Galton. It was a pachycephalosaurid dinosaur that lived during the Late Cretaceous period, around seventy-five million years ago. Made up of only one species, paleontologists debate on whether the fossil specimen is synonymous with Stegoceras, or if it is its own genus, although recent papers indicate it may be a valid genus.

During their expedition on Isla Sorna in 1995, Dr. Richard Levine states that the dark green animals with domed heads are either Gravitholus or more likely Pachycephalosaurus wyomingensis, though it’s hard to say for sure, since both animals have never been discovered with a full skeleton.
