Description
Pachycephalosaurus is an herbivorous dinosaur that lived in North America during the Late Cretaceous period. The name Pachycephalosaurus translates to ‘thick-headed lizard’, in reference to the genus’ large, thick skull that experts believe was used in intra-species combat, with rival dinosaurs attacking each other when competing for territory. Growing up to 4.5m in length and weighing almost half a ton, Pachycephalosaurus is one of the largest pachycephalosaurid dinosaurs.
Discovery
American geologist and fossil collector Ferdinand Vandeveer Hayden discovered the first Pachycephalosaurus specimen in 1859 when he found a fragment of bone in the Lance Formation, Montana. The fossil was not originally thought to be that of a dinosaur but a reptile or armadillo, and it wasn’t until 1985 that it was formally classified as a new genus, named Pachycephalosaurus.
Paleoecology
This genus lived around 65-75m years ago in the western United States, co-existing with many other dinosaurs including Edmontosaurus, Triceratops and the fearsome apex predator Tyrannosaurus. It is believed that Pachycephalosaurus lived in wooded areas, feeding on soft plants, fruit and seeds.
