The Pachycephalosaurus, a distinctive dinosaur of the late Cretaceous period, stands out among its prehistoric peers due to its unique features and behaviors. By reading this article you will get a better understanding of the Thick Headed Lizard.


Ankylosaurus, a formidable armored dinosaur, was a colossal creature that roamed the Earth during the late Cretaceous period, approximately 70 to 65 million years ago.


Dilophosaurus was a speedy, slender, bipedal (walked on two legs), meat-eater that lived during the early Jurassic period. It was a theropod (a meat-eating dinosaur) about 20 feet (6 m) long, about 5 feet (1.5 m) tall at the hip, and weighing about 650 to 1,000 pounds (300 kg to 450 kg). It had two thin, bony, almost semi-circular crests on its head; these may have been for mating displays.


Diplodocus, one of the largest dinosaur ever.


Psittacosaurus (meaning “parrot lizard”) was a small, very primitive ceratopsian. This fast-moving plant-eater had a narrow, horny beak with no teeth, and cheek teeth towards the rear of the mouth. It had a boxy skull with short, horn-like projections on the cheeks. It had four long fingers on each hand; the arms were much shorter than the legs.
