A Top Quality, Ultra Rare Pachychephalosaurus wyomingensis spike cluster from the late Cretaceous of northern North America. A June Fossil of the Month. Pachychephalosaurus is the dinosaur which is famous for its large domed head surrounded by these spikes and nodes. These spikes and nodes were part of the Pachy skull. This is a node cluster with two large nodes surrounded by a large group of smaller nodes. This node cluster has excellent color and patina with exceptional surface articulation. The blood grooves are still present in the bone. It is a complete specimen with no cracks or breaks. Note - the excellent articulated skull surface on the base of the node. Legally collected on private land in the Hell Creek Fm., Powder River Co., Montana. An excellent collector's quality Pachychephalosaurus spike. You don't see these skull pieces very often. No repair or restoration. Authenticity guaranteed. My best Pachy node cluster!
