The order Stygimoloch

order The name of this pachycephalosaurid derives from it's frightful appearance. Moloch was a horned devil in Hebrew mythology, and in Greek legend the river styx was the river that the dead had to cross to reach the underworld. The fossils were found in hell creek formation in Montana, and this was a further inspiration for the name. The first Stygimoloch horn core was found in 1896 and and regarded as part of a Triceratops skull. In the 1940s, when pachycephalosaurids were recognized, it was classified as a species of pachycephalosaurus.
