Stenopelix is one of the innumerable dinosaurs of the early Cretaceous period that have been reconstructed from fragmentary remains, and as such, paleontologists aren't quite sure what to make of it. The preponderance of opinion has been to classify it as a pachycephalosaur ("thick-headed lizard")--not because of the thickness of its skull, but because of the characteristic shape of its pelvis--but some experts think Stenopelix may have been an ornithopod, and others insist the remains don't add up to any convincing genus at all!
