Onychodontida (= Onychodontiformes or Struniiformes) is an order of prehistoric sarcopterygian fish that lived between Late Silurian to Late Devonian period. The onychodontiformes are probably a paraphyletic group of basal sarcopterygians.
Phylogeny
Based on a phylogram by Long, 2001, and Lu & Zhu, 2009 and presented in Mikko's Phylogeny Archive
A new phylogenetic analysis of sarcopterygians, incorporating new fossils of Qingmenodus and neurocranial characters previously neglected, supported Onychodontiformes as stem-coelacanths within Actinistia.
