Length, dimensions, size of Pachycephalosauria (Pachycephalosaurs)

Pachycephalosaurs were bipedal ornithischians characterized by their thickened skulls. They had a bulky torso with an expanded gut cavity and broad hips, short forelimbs, long legs, a short, thick neck, and a heavy tail. Large eye sockets (orbits) and a large optic nerve point to pachycephalosaurs having good vision, and uncharacteristically large olfactory lobes indicate that they had a good sense of smell relative to other dinosaurs. They were fairly small dinosaurs, with most falling in the range of 2–3 meters (6.6-9.8 feet) in length and the largest, Pachycephalosaurus wyomingensis, estimated to measure 4.8 meters (15.7 feet) long and weigh 500 kilograms (110 pounds).

Today we present the world’s largest list of Pachycephalosaurs (Pachycephalosauria) ranked by length. Soon we will present a list of the heaviest Pachycephalosaurs (Pachycephalosauria).
