After half a century of debate, a University of Alberta researcher has confirmed that dome-headed dinosaurs called pachycephalosaurs could collide with each other during courtship combat. Eric Snively, an Alberta Ingenuity fellow at the U of A, used computer software to smash the sheep-sized dinosaurs together in a virtual collision and results showed that their bony domes could emerge unscathed.

Troodon, meaning “wounding tooth,” is a genus of bird-like dinosaur from the Late Cretaceous Period (76 to 65 million years ago). Troodon was discovered in 1855 in North America and was one of the first dinosaurs found there. Fossils of this specimen have been found from Alaska to Wyoming, with possible Troodon fossils also being found in Texas and New Mexico. Troodon is known from the Judith River Formation and the upper Two Medicine Formation of Montana, the Judith River Group of...

Alaskacephale is a genus of dinosaur from the late Campanian stage of the Late Cretaceous Period (80 to 70 million years ago). It was first described by Roland Gangloff and colleagues as an unnamed pachycephalosaurid, possibly a Pachycephalosaurus, but after further studies it was determined to have dissimilar characteristics. It was given the name Alaskacephale by Robert Sullivan in 2006. The name Alaskacephale refers to Alaska, where the fossil was found. The species name anglophile,...

Homalocephale, meaning "even head", is a genus of dinosaur from the Late Cretaceous Period. It lived in what is now Mongolia, more than 80 million years ago. It was described in 1974 and consists of a single species. The type species is H. calathocercos. This 10 foot long herbivore had a flat, wedge-shaped skull, hence its name. The reason for the thick flat skull is believed to be for males that competed in head-butting rituals, similar to that of modern-day iguanas. The pelvis is broad,...

Dracorex, meaning "dragon king", is a genus of dinosaur from the Late Cretaceous Period of North America. The type species, D. hogwartsia, is known from one nearly complete skull and four cervical vertebrae. The remains were discovered in the Hell Creek Formation in South Dakota by a group of amateur paleontologists from Sioux City, Iowa. It was formally described by Bob Bakker and Robert Sullivan in 2006. The species name hogwartsia was inspired by the Harry Potter series of books by J.K....
