Ecrinesomus is an extinct genus of prehistoric marine bobasatraniiform ray-finned fish that lived during the late Induan age of the Early Triassic epoch. It is known from the Sakamena Formation of Madagascar.[1][2]

Appearance

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.[3]
