Morphological Comparison

Caption

Morphological comparison between the Liscomb Bonebed hadrosaurine (left fossils) and known Edmontosaurus (right fossils). The hadrosaurid possesses a short dorsolateral process of the laterosphenoid, one of the diagnostic characters of Edmontosaurus (A). Some features previously considered unique to Ugrunaaluk were also found in Edmontosaurus or appear only transiently during the growth. (B-D)
