Of fossil gonorynchiformes dates back to cuvier in the early 19th century, and there is still a need for a critical review of the earliest descriptions and of some key taxa today.

Fossil gonorynchiform fishes range from the lower cretaceous to the early miocene, and are represented by a few dozen living species. The order is currently divided into two major clades: gonorynchoidei, which includes the families gonorynchidae and kneriidae, and chanoidei, encompassing a single family, chanidae, with a single recent species, the indo-pacific chanos chanos, and several fossil.

Gonorynchoidei includes two families gonorynchidae and kneriidae. Gonorynchidae is formed by ( gonorynchus† notogoneus) and four fossil taxa of uncertain definition and interrelationships: †charitosomus† charitopsis† ramallichthys, and †fudeichthys. The last four genera were previously included in the families †charitosomidae and †judeichthyidae, which could not be supported as monophyletic in this analysis.
Abstract new sphenodontian material is described from the early cretaceous (?berriasian) of morocco. The first is represented by a dentary and, probably, a partial maxilla.

The order gonorynchiformes is represented herein by 18 genera, extending back to the early cretaceous. More work is required to clarify the interrelationships of the gonorynchidae and the paedomorphic characters that apparently played an important role in the evolution of this morphologically diverse group of fishes.
