Abiadisaurus is an extinct genus of prehistoric amphibian from the Temnospondyli clade, considered to be a member or a relative of the family Mastodonsauridae. It is known solely from the Late Triassic or Early Jurassic Adigrat Sandstone northwest of Abi Adi, Tigray, Ethiopia.[1][2] The Age debate of this taxon comes in part due to the fact the Adigrat Sandstone is believed to be diachronous, with a top age of Callovian(?) to early Oxfordian marine Antalo Limestone and the Hamanlei Formation, but some beds overlie Paleozoic formations.[3] These sandstones were deposited on top of the partially eroded Triassic surface, primarily in fluvial or piedmont environments, but also in fluviolacustrine and deltaic settings.[4]
