Onychodontidae

Onychodontidae is an extinct family of sarcopterygian fishes which lived during the Early Devonian and Middle Devonian period. Onychodontid fossils have been discovered in the United States, Russia and Australia, during a period spanning approximately 82 million years.[1] The Onychodontidae was first described in 1891.[2]

A new phylogenetic analysis of sarcopterygians, incorporating new fossils of Qingmenodus and neurocranial characters previously neglected, supported Onychodontiformes as stem-coelacanths within Actinistia.[4]
