One of the newer pachycephalosaurs (bone-headed dinosaurs) on the block, Alaskacephale was named in 2006 after the state of the U.S. where its incomplete skeleton was found. Originally thought be a species (or perhaps a juvenile) of Pachycephalosaurus, it was later "diagnosed" as belonging to its own genus based on slight variations in its skeletal structure.
