四足形亚纲 Tetrapodomorpha
（重定向自Tetrapodomorph）
四足形亚纲（Tetrapodomorpha）是一群介于鱼类与两栖类之间的过渡物种（但属于鱼类），牠们演化出具骨骼的肉质鳍，是演化的关键，因为这些史前动物告诉着我们脊椎动物是怎样从海洋移到陆地上的。动物们生存于约四亿年前的泥盆纪，现已全部灭绝，其现代近亲为肺鱼和两栖类（其直系后代）。

![The exact shape of the phylogenetic tree is uncertain with Zachelmie tetrapod tracks predating most tetrapodomorph fossils[4]](/uploads/202502/15/Zachelmie_tracks_vs_selected_Devonian_fossils.svg3817.png)
The Tetrapodomorpha (also known as Choanata) are a clade of vertebrates consisting of tetrapods (four-limbed vertebrates) and their closest sarcopterygian relatives that are more closely related to living tetrapods than to living lungfish. Advanced forms transitional between fish and the early labyrinthodonts, such as Tiktaalik, have been referred to as "fishapods" by their discoverers, being half-fish, half-tetrapods, in appearance and limb morphology. The Tetrapodomorpha contains the crown group tetrapods (the last common ancestor of living tetrapods and all of its descendants) and several groups of early stem tetrapods, and several groups of related lobe-finned fishes, collectively known as the osteolepiforms. The Tetrapodamorpha minus the crown group Tetrapoda are the Stem Tetrapoda, a paraphyletic unit encompassing the fish to tetrapod transition.
