TL;DR: Poropat et al. as mentioned in this paper described the oldest meiolaniid remains from Australia to date, consisting of a posterior peripheral, a caudal ring and an osteoderm, all of which derive from the middle-upper Eocene Rundle Formation of The Narrows Graben, Gladstone, eastern Queensland.
Abstract: Poropat, S.F., Kool, L., Vickers-Rich, P. & Rich, T.H., September 2016. Oldest meiolaniid turtle remains from Australia: evidence from the Eocene Kerosene Creek Member of the Rundle Formation, Queensland. Alcheringa 41, XX–XX. ISSN 0311-5518.Fossil meiolaniid turtles are known only from South America and Australasia. The South American record is restricted to the Eocene, and comprises two genera: Niolamia and Gaffneylania. The Australasian meiolaniid record is more diverse, with three genera known (Ninjemys, Warkalania and Meiolania); however, the oldest known specimens from this continent are significantly younger than those from South America, deriving from upper Oligocene sediments in South Australia and Queensland. Herein, we describe the oldest meiolaniid remains found in Australasia to date. The specimens comprise a posterior peripheral, a caudal ring, and an osteoderm, all of which derive from the middle–upper Eocene Rundle Formation of The Narrows Graben, Gladstone, eastern Queensland. Despite the...
TL;DR: Ninjemys is a meiolaniid genus from the Pleistocene of Queensland, Australia as mentioned in this paper, which is distinguished from all others by its unique properties: large squamosal horndirected laterally rather thanposterolaterally asin Niolamia and Meiolania, nasal bonesprojecting anteriorly beyondrestofskull, medial accessory ridge ontriturating surface extending nearly tomidline.
