Sheet1 Comparative Anatomy ? Taxonomy The following is an indented taxonomy that you will be required to know for the first exam. Indented taxonomies differ from traditional taxonomies in that there is no assignment of rank to the taxonomic levels. In addition to taxonomic groups, a few paraphyletic assemblages are also included below; these paraphyletic assemblages are surrounded by quotation marks. This is not an exhaustive list of taxa. Chordata Urochordata Ascidacea ? sea squirts Cephalochordata ? lancets or amphioxus Craniata Myxini (Hyperotreti) - Hagfishes Vertebrata Hyperoartia (Petromyzontiformes) - lampreys Euconodonta ? conodonts Pteraspidomorpha ? ostracoderms Osteostraci - ostracoderms Gnathostomata Placodermi ? placoderms Chondrichthyes Elasmobranchii ? sharks, skates, and rays Holocephali ? chimaeras Teleostomi Acanthodii ? acanthodians or spiny sharks Osteichthyes Actinopterygii ? ray-finned fishes Cladistia - bichirs Chondrostei ? sturgeons and paddlefishes Neopterygii Lepisosteiformes ? gar Amiiformes ? bowfin Teleostei ? teleosts (most fishes) Sarcopterygii ? lobe-finned fishes and tetrapods Actinistia ? coelacanths Dipnoi ? lungfishes "Osteolepimorpha" - our closest fish relatives Tetrapoda ? four-legged animals and their descendents Tetrapoda ? four-legged animals and their descendents "Labyrinthodonts" ? early tetrapods Amphibia Lissamphibia Urodela (Caudata) ?
