DescriptionThis specimen, MZ VIII Vr-72 was orginally described in 1972 by Maryańska, as pliosaurid Peloneustes. After reading notion of Ketchum and Benson (2011), that this partially uncovered rostrum may belong to teleosauroid, we decided to prepare the block of limestone. After additional preparation, the rostrum can be identified as belonging to the telosauroid indeed, and more precisely to Machimosaurinae, with likely close affiliation with genera Neosteneosaurus and Proexochokefalos. Most notably, the anteriormost part of the rostrum exhibits prominent lateral bend, which is interpreted by us as in-vivo condition, and not a result of diagenetic disfiguration of fossil.
