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.
