Challaia is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Triassic period in what is now Argentina ( Mendoza). [4] Two species are known, C. magna ( type species), most likely from the Cerro de Las Cabras Formation, and C. elongata (previously assigned to Myriolepis) from the Los Rastros Formation. [5] [1] Three other species, C. multidentata, C. striata and C.? cacheutensis, are considered nomina dubia. [1] [3]
C. elongata is the youngest known member of the Acrolepididae, a family of early ray-finned fishes that was dominant throughout the late Paleozoic, and survived into the Triassic. [6]
