Hoplitidae
The Hoplitidae is a family of Cretaceous ammonites that lived during the middle of the period from the late Aptian to the Cenomanian. They are part of the superfamily Hoplitoidea. Members of the Hoplitidae are typically evolute, with inner whorls exposed, although some are more involute, and are commonly stout and strongly ribbed, with pronounced tubercles. The Hoplitidae are thought to be derived from the U Aptian -M Albian '' Uligella'' of the Desmoceratidae, or some related form and have been divided into three subfamilies. Subtaxa Classification of Hoplitidae was revised multiple times during last decades. Currently, is contains 3 subfamilies:Amédro, F., Matrion, B., Magniez-Jannin, F., & Touch, R. (2014).

Anahoplites
''Anahoplites'' is a genus of rather involute, compressed hoplitid ammonites Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) ... with flat sides, narrow flat or grooved venters, and flexious ribs or striae arising from weak umbilicle tubercles that end in fine dense ventrolateral nodes. The elements of their sutures are short, wide and jaggedy. Specimens of ''Annahoplites'' have diameters typically in the range of although some with diameters of as much as have been reported. The genus lived during the Cretaceous, from the Middle to the late Albian. ''Anahoplites'' is now included in the subfamily Anahoplitinae and separated from the Hoplitinae where it was placed in the older, 1957 edition of the Treatise on Invertebrate Paleontology, Part L (Ammonoidea).

Callihoplites
''Callihoplites'' is a genus of rather evolute ammonites from the Lower Cretaceous, Late Albian. Its whorl section squarish or compressed, inner whorls bearing umbilical bullae and ventrolateral clavi, with or without looped ribs between. The body chamber is smooth with a rounded venter. ''Callihoplites'' is a member of the ammonitid family Hoplitidae and superfamily Hoplitoidea Hoplitoidea, formerly Hoplitaceae, is a superfamily of mostly Upper Cretaceous ammonites comprising families united by a similar suture pattern with multiple similar elements that tend to decrease in size going toward the umbi ..., now also known as the Hoplitoidea.

Otohoplites
''Otohoplites'' is a genus of ammonite that lived in the Early Albian age and whose fossils were found in Svalbard, Denmark, England, France, Austria, Poland, Russia and Kazakhstan. It has evolved from '' Hemisonneratia'' and gave rise to the genus ''Hoplites Hoplites ( ) ( grc, ὁπλίτης : hoplítēs) were citizen-soldiers of Ancient Greek city-states who were primarily armed with spears and shields.

Hoplites (ammonite)
Hoplites ( ) ( grc, ὁπλίτης : hoplítēs) were citizen-soldiers of Ancient Greek city-states who were primarily armed with spears and shields. Hoplite soldiers used the phalanx formation to be effective in war with fewer soldiers. The formation discouraged the soldiers from acting alone, for this would compromise the formation and minimize its strengths. The hoplites were primarily represented by free citizens – propertied farmers and artisans – who were able to afford a linen armour or a bronze armour suit and weapons (estimated at a third to a half of its able-bodied adult male population). Most hoplites were not professional soldiers and often lacked sufficient military training. Some states maintained a small elite professional unit, known as the '' epilektoi'' ("chosen") since they were picked from the regular citizen infantry. These existed at times in Athens, Argos, Thebes, and Syracuse, among other places. Hoplite soldiers made up the bulk of ancien ...
