Araripelepidotes is a genus of ginglymodian 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.{{Cite journal|last1=Brito|first1=Paulo M.|last2=Yabumoto|first2=Yoshitaka|date=March 31, 2011|title=An updated review of the fish faunas from the Crato and Santana formations in Brazil, a close relationship to the Tethys fauna|url=https://www.kmnh.jp/wp-content/uploads/2017/06/A9-107-E-Brito_Yabumoto.pdf|journal=Bull.

Taxonomic history
The type species A. temnurus was formerly placed in the genus Lepidotes, until it was moved to the new genus in 1990.{{Cite journal|last1=Brito|first1=Paulo M.|last2=Yabumoto|first2=Yoshitaka|date=March 31, 2011|title=An updated review of the fish faunas from the Crato and Santana formations in Brazil, a close relationship to the Tethys fauna|url=https://www.kmnh.jp/wp-content/uploads/2017/06/A9-107-E-Brito_Yabumoto.pdf|journal=Bull. Kitakyushu Mus. Nat. Hist. Hum. Hist., Ser. A|volume=9|pages=107–136}} 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.{{Cite journal |last=López-Arbarello |first=Adriana |date=2012-07-11 |title=Phylogenetic Interrelationships of Ginglymodian Fishes (Actinopterygii: Neopterygii) |journal=PLOS ONE |language=en |volume=7 |issue=7 |pages=e39370 |doi=10.1371/journal.pone.0039370 |issn=1932-6203 |pmc=3394768 |pmid=22808031 |bibcode=2012PLoSO...739370L |doi-access=free }}
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.{{Cite journal|last=Thies|first=Detlev|date=1996-09-19|title=The jaws of Araripelepidotes temnurus (Agassiz, 1841) (Actinopterygii, Semionotiformes) from the Early Cretaceous of Brazil|url=https://www.researchgate.net/publication/232882843|journal=Journal of Vertebrate Paleontology|volume=16|issue=3|pages=369–373|doi=10.1080/02724634.1996.10011326|jstor=4523729|bibcode=1996JVPal..16..369T }} It is the only lepisosteiform known from the Araripe Basin, except for Lepidotes wenzae.{{Cite journal|last1=Brito|first1=Paulo M.|last2=Yabumoto|first2=Yoshitaka|date=March 31, 2011|title=An updated review of the fish faunas from the Crato and Santana formations in Brazil, a close relationship to the Tethys fauna|url=https://www.kmnh.jp/wp-content/uploads/2017/06/A9-107-E-Brito_Yabumoto.pdf|journal=Bull.
