Velociraptor) Tyrannosauridae Integument ´Ornithischia Scales = 0 Maniraptora Filaments = 1 Theropoda Saurischia Branched Filaments = 2 The tree above is a simplified version of the prevailing hypothesis of the relationships between various dinosaurs and dinosaur groups. The legend on the bottom left reflects three basic conditions that describe the character that pertains to body covering (or integument). The conditions that pertain to the specific taxa at the top of the tree are shown by the numbers. Dinosauria Trace the integument character along the tree (you may want draw it out on a separate sheet of paper). Once you have done that step, consider the ancestor of all dinsoaurs. What character condition did you get? Crocodiles Pterosauria O (ex. Pteroda O (ex. Stegosaurus) Kul indadromeus Psaurus (ex.…
