Hemihoplites is an extinct genus of ammonoid cephalopods belonging to the family Hemihoplitidae.[2] These fast-moving nektonic carnivores[1] lived in the Cretaceous period, from the Hauterivian age to the Barremian age.[3]
It is evolute, compressed. The Whorl section is rectangular. The ribs are simple or branching or long or short, well spaced, straight or slightly flexuous, crossing flat venter transversely, typically with distinct umbilical and ventrolateral tubercles.[2]
