'''''Coccoderma''''' is a [[genus]] of [[prehistoric]] [[coelacanth]] [[lobe-finned fish]] which lived during the [[Jurassic]] period. [[Fossils]] have been found in [[USA]]. It was small in size, about 27,5 cm.

It was one of the earliest coelacanths to be properly studied by science.<ref name=":1" /> It lived far later than other members of its family ([[Laugiidae]]), which otherwise only existed during the [[Early Triassic]], thus leaving an exceptional [[ghost lineage]] of over 100 million years. It was the last surviving member of the non-[[Coelacanth|latimerioid]] coelacanths (e.g. coelacanths outside of [[Latimeriidae]] and [[Mawsoniidae]]).<ref>{{Cite journal |last=Toriño |first=Pablo |last2=Soto |first2=Matías |last3=Perea |first3=Daniel |date=2021-12-02 |title=A comprehensive phylogenetic analysis of coelacanth fishes (Sarcopterygii, Actinistia) with comments on the composition of the Mawsoniidae and Latimeriidae: evaluating old and new methodological challenges and constraints |url=https://www.tandfonline.com/doi/full/10.1080/08912963.2020.1867982 |journal=Historical Biology |language=en |volume=33 |issue=12 |pages=3423–3443 |doi=10.1080/08912963.2020.1867982 |issn=0891-2963|url-access=subscription }}</ref>
