Superclass Agnatha Ostracoderms first to appear in fossil records during the Cambrian period Class Myxini Hagfish o Superclass Gnathostomata Jawed fish Class Chondrichthyes cartilaginous fish like sharks Class Sarcopterygii lobe finned fish Class Actinopterygii ray finned fish we eat o Class Amphibia first tetrapods first appear in Devonian Period o Class Reptilia first appear in Carboniferous Period Subclass Anapsida turtles Subclass Lepidosauria lizards snakes Archosauria ancestor to crocodiles alligators and birds o Class Aves birds first appeared in Jurassic Period o Class Mammalia mammals first appeared in Triassic Period Infraclass Methatheria Marsupials include kangaroos koalas Subclass Prototheria egg laying mammals platypus Know how to read chart on pg 5 of book Species listed higher vertically on the chart are more primitive Species further to the left appeared earlier in the fossil record Black lines represent diversity the wider the line the more diverse EX On chart Neopterygianii ray finned fish take up the most space in black so they are the most diverse species on the chart Second most diverse species are the Aves birds o Remember this info in the fossil record Ostracoderms including Myxini as a class Cambrian Pd Mammals Triassic Pd Amphibians aka first tetrapods Devonian Pd Reptiles Carboniferous Pd Birds aka Aves Jurassic Pd Videos to remember o
