Abstract
A skeletal reconstruction of the small protoceratopsian dinosaur Leptoceratops gracilis from the latest Cretaceous of Alberta is presented. Leptoceratops has a greater number of presacral vertebrae than in other known protoceratopsids, and the presacral vertebral count is recognized to be somewhat variable in ceratopsids as well. Psittacosaurids, protoceratopsids, and ceratopsids represent distinct lineages of the same general group of ornithischian dinosaurs.
