Ninjemys oweni is an extinct large meiolaniid stem-turtle from Pleistocene Queensland and possibly New South Wales ().It overall resembled its relative, Meiolania, save that the largest pair of horns on its head stuck out to the sides, rather than point backwards, the larger scales at the back of its skull and the tail club which is made up of only two tail rings rather than four.
Modern turtles have a horny beak without teeth in their mouth. In contrast, Odontochelys fossils were found to have had teeth embedded in their upper and lower jaws. [4] One of the most striking features of turtles, both modern and prehistoric alike, are their dorsal shells, forming an armored carapace over the body of the animal.

For example, the site’s Turtle Lagoon exhibit mimics the sea creature’s natural surroundings,and the Open Ocean exhibit holds 18,000 gallons of saltwater and plays host to more than 50 species ...
A unique feature of the Mary River turtle is the very large tail of males, which can measure almost two-thirds of the carapace length. Also unusual is that the tail is laterally compressed like a paddle. The tail also has haemal arches, a feature lost in all other Australian chelids.
