Zanclites xenerus Jordan, 1924 Zanclites is an extinct genus of prehistoric ray-finned fish.

[2] Zanclites is a member of the Tselfatiiformes, a group of fish typical of the Cretaceous period and usually endowed with large dorsal fins.

In particular, Zanclites would appear to have been a member of the Plethodidae family.

Zanclites xenurus was first described by Jordan in 1924, based on a well-preserved fossil from the Niobrara Formation in Kansas (United States).

Other fish belonging to the same family found in the same formation are Niobrara and Pentanogmius.
