This is a large wonderful skull spike from the infamous American Dome Headed dinosaur Pachycephalosaurus from the equally infamous Hell Creek Formation in Montana, USA! These strange herbivores, nearly 15 feet long and one thousand pounds, roamed North America from 70 to 65 million years ago. They fed on soft leaves, seeds, and fruit, slicing them up with their (surprisingly) small leaf-shaped serrated teeth. Their most striking feature being the large dome on their skull, up to 9 inches thick! The exact purpose of this dome has been debated for decades. The most well know theory is that the animals used their domes in "headbutting contests" similar to modern bighorn sheep. The domes were very ornate, being surrounded by boney knobs and spikes like this specimen! The piece measures 1.81 inches (4.6 cm) long, 1.57 inches (4 cm) tall, and 1.02 inches (2.6 cm) wide with a great texture and with zero repair or restoration! A fantastic piece from a bizarre, iconic, and surprisingly rare dinosaur worthy of any fossil collection!

All of my items come with a Certificate of Authenticity!
