Cladocyclidae
Ichthyodectiformes is an extinct order of marine stem-teleost ray-finned fish. The order is named after the genus ''Ichthyodectes'', established by Edward Drinker Cope in 1870. Ichthyodectiforms are usually considered to be some of the closest relatives of the teleost crown group. They were most diverse throughout the Cretaceous period, though basal forms like ''Thrissops, Occithrissops'' and ''Allothrissops'' are known from the Middle-Late Jurassic of Europe and North America. Most ichthyodectiforms ranged between 1 and 5 meters (3–15 ft) in length. Most of known taxa were predators, feeding on smaller fish; in several cases, larger ichthyodectiforms preyed on smaller members of the order. Some species had remarkably large teeth, though others, such as ''Gillicus arcuatus'', had small ones and sucked in their prey. '' Heckelichthys preopercularis'' is a rare example of non-predatory ichthyodectiform, more likely to be microphagous, fed on small particles. There is evidence ...

Cladocyclus
''Cladocyclus'' (derived from the Greek κλάδος/kládos ("branch") and κύκλος/kýklos ("circle")) is an extinct genus of Ichthyodectidae. It was a predatory fish of about in length, found in the Albian Romualdo and Crato Formations of the Araripe Basin in northeastern Brazil. A new species, ''Cladocyclus pankowskii'', was discovered in the Cenomanian Akfabou Formation of Morocco in 2007, and in the Upper Plattenkalk of Italy.''Cladocyclus''
