Araripelepidotes is a genus of semionotiform fish.

Habitat[]

Araripelepidotes was probably endemic to the Araripe Basin, and was commonly found in Santana formation, and rare in the Crato Formation, mostly in carbonate concretions, but uncommon in laminated limestones.^[1]^[2]

Taxonomic history[]

The type species A. temnurus was formerly placed in the genus Lepidotes, until it was moved to the new genus in 1990.^[1]

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.^[3] It is the only semionotidid known from the Araripe Basin, except for .^[1]
