Descripción: A scale diagram comparing three parksosaurid dinsosaur genera, Orodromeus, Parksosaurus and Thescelosaurus to a Human. • Parksosaurus silhouette is based on File:Parksosaurus Steveoc86.jpg, which is based proportionally on a reconstruction in[1] scaled to a femur length of 270mm.[2] • Orodromeus silhouette is based on a skeletal reconstruction by Scott Hartman, used with permission.[1] Scaled based on data in Scheetz 1999.[3] • Thescelosaurus silhouette is based on a skeletal by Genya Masukawa, used with permission. Silhouettes were scaled using the scale bars provided.[2] • The feathery outlines are speculative but based loosely on related dinosaurs. In 2009 the Heterodontosaur Tianyulong was described, which shows filamentous quill-like structures along its back and underside.[4] In 2014, Kulindadromeus was described and showed a mix of feather-like structures and scales.[5] • Humans 170 cm and 160 cm, respectively.References ↑ Paul, G.S. , ed.
