Gryponyx transvaalensis				Bushveld Sandstone	A single claw from the hand and a wrist bone
Magyarosaurus transsylvanicus	BMNH R3896, 4891					Generally considered a junior synonym of M. dacus
Orosaurus capensis						Was renamed Orinosaurus because Orosaurus was believed to be preoccupied, but this mistake was realized and Orinosaurus is an objective junior synonym; has also been referred to the genus Gresslyosaurus
Plateosaurus ornatus						May be a nomen dubium
Plateosauravus stormbergensis
Pleurocoelus montanus
Tangvayosaurus falloti
Titanosaurus falloti
