Ecrinesomus is an extinct genus of prehistoric bobasatraniiform ray-finned fish that lived during the Induan age of the Early Triassic epoch in what is now Madagascar.[1]

Appearance[edit]

Ecrinesomus co-occurred with the relatively similar looking Bobasatrania. Fossils of these two genera are sometimes misidentified, but can be distinguished based on the following characters: the number of scale rows (Ecrinesomus has ca. 48 transversal scale rows, Bobasatrania has fewer), the body shape (Ecrinesomus has an elliptical, Bobasatrania a rhombic body outline) and the distinct skull bone pattern.[2]
