Pleurohoplites is a genus in the ammonitid family Hoplitidae, found in middle Cretaceous (Upper Albian - Cenomanian) of Europe, and included in the subfamily Hoplitinae. [1]
Pleurohoplites has a somewhat involute, compressed to rather inflated shell, with a rounded to subcoronate venter, that bears umbilical tubercles from which branch strong, un-looped, ribs that end in ventrolateral nodes, or are continuous to the siphonal line.
Euhoplites is an extinct ammonoid cephalopod from the Lower Cretaceous, characterized by strongly ribbed, more or less evolute, compressed to inflated shells with flat or concave ribs, typically with a deep narrow groove running down the middle. In some, ribs seem to zigzag between umbilical tubercles and parallel ventrolateral clavi. In others the ribs are flexuous and curve forward from the umbilical shoulder and lap onto either side of the venter.
