Diagnosis
ReferenceDiagnosis
A. Bolet and S. E. Evans 2010Pedrerasaurus resembles Meyasaurus and differs from all other described Jurassic and Early Cretaceous lizards in having bicuspid posterior teeth, but differs from Meyasaurus in having broader, paired frontal bones (fused and very narrow in Meyasaurus) with the median suture showing strong interdigitations in its posterior half, rugose rather than vermiculate sculpture on the skull bones, a slender, rather than expanded squamosal, shorter postparietal processes on the parietal, and less disparity in length between the anterior and posterior dorsal ribs. Pedrerasaurus resembles Ardeosaurus from the Jurassic Solnhofen Limestone in having paired frontals with an interdigitated suture, but differs in having: shorter postparietal processes; a narrower squamosal (it is broader, dorsoventrally flattened, and restricts the upper temporal fenestra in Ardeosaurus); a braincase that is completely covered by the parietal (it is exposed for some distance behind it in Ardeosaurus): no osteoderms on the skull; and a higher number of presacral vertebrae (26 v. 23 in Ardeosaurus). The tooth tip morphology of Ardeosaurus is currently unknown.
