             English: Sketch of a pachycephalosaur of uncertain systematical position and still (2003) not formally described. Its remains were found in the "Sandy Quarry" of the Hell Creek Formation, near Buffalo, South Dakota (USA). Initially reconstructed as Pachycephalosaurus wyomingensis by Michael Triebold later many attendees of an international symposium referred the remains to Stygimoloch spinifer because of the prominent spikes on the back of the skull.

Seine Überreste wurden in „Sandy Quarry“, in der Hell-Creek-Formation, nahe Buffalo in South Dakota (USA) gefunden. Anfangs von Michael Triebold als Pachycephalosaurus wyomingensis rekonstruiert, bezeichneten viele Teilnehmer einer internationalen Fachtagung die Überreste wegen der großen Stacheln am Hinterhaupt als Stygimoloch spinifer.
