Description and biology
editInermorostrum is largely distinguished from other xenorophiids in having a greatly reduced rostrum devoid of functional teeth. The short, toothless rostrum is unusual for early odontocetes, showing that Inermorostrum mostly preyed on squids and other marine invertebrates by means of suction-feeding.[1]
