Ardoreosomus

Ardoreosomus is an extinct genus of marine ray-finned fish. It was described from the Induan aged Candelaria Formation of Nevada, United States, which was located near the equator during the Early Triassic epoch. It contains only one species, A. occidentalis.
Ardoreosomus is a ptycholepiform, closely resembling Boreosomus and Ptycholepis; however, Ardoreosomus is distinguished from other ptycholepiforms in having a more strongly angled hyomandibula and lacking an opercular process, among other features.
