About Abiadisaurus
Abiadisaurus is an extinct genus of prehistoric amphibians 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. 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. 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.
