Kranaosphinctes is an extinct genus of ammonites belonging to the Perisphinctidae family.[2] Some authors consider Kranaosphinctes a subgenus of the genus Perisphinctes. [3]
Fossils of Kranaosphinctes are found in marine strata of the Upper Jurassic (age range: from 161.2 to 155.7 million years ago.). Fossils are known from some localities of Europe, Argentina, India and Madagascar.[3][4][5]
