Araripe Basin The Araripe Basin () is a rift basin covering about ,Neto et al., 2013, p.1 in Ceará, Piauí and Pernambuco states of northeastern Brazil. It is bounded by the Patos and Pernambuco lineaments, and is situated east of the Parnaíba Basin, south ...

Taxonomic history

The type species ''A. temnurus'' was formerly placed in the genus '' Lepidotes'', until it was moved to the new genus in 1990. Formerly placed in the Semionotiformes, more recent morphological studies indicate that it is more closely related to extant gar, and is in fact more closely related to gar than "true" lepidotids such as ''Lepidotes''.


Paleoecology

''Araripelepidotes'' was likely a toothless suction feeder, due to the development of its mobile maxilla and the presence of an interoperculum, and would have inhabited estuarine and freshwater environments. It is the only lepisosteiform known from the Araripe Basin, except for '' Lepidotes wenzae''.
