One such species, N. procerus, is now considered a junior subjective synonym of N. marchicus. Several other species have been named but are now generally considered invalid. Klein and Albers (2009) conducted a phylogenetic analysis, but did not test the monophyly of Nothosaurus, as other nothosaurids were not included in their analysis. Recently, the long considered lost type material of N. schimperi Meyer, 1842 from the Lower Muschelkalk of Soultz-les-Bains, Alsace, France, has been rediscovered and a lectotype has been designated. Several species have been described from the Lower Muschelkalk in Winterswijk, the Netherlands, including N. marchicus (and its junior synonym N. winterswijkensis ) and N. winkelhorsti.
Other species include N. giganteus (previously known as Paranothosaurus) from Osnabrück, Germany N. juvenilis, also from Germany N. edingerae from the Upper Muschelkalk and Lower Keuper N. haasi and N. tchernovi from Makhtesh Ramon, Israel N. cymatosauroides from the Spanish Muschelkalk N. jagisteus from the Upper Muschelkalk of Hohenlohe, Germany and N. youngi, N. yangjuanensis (and its junior synonym N. rostellatus) and the recently named N. zhangi from Guizhou, China.
The type species is N. mirabilis, named in 1834 from the Germanic Muschelkalk. There are nearly a dozen known species of Nothosaurus. It is thought that one branch of the nothosaurs may have evolved into pliosaurs such as Liopleurodon, a short-necked plesiosaur that grew up to 6.4 metres (21 ft), and the long-necked Cryptoclidus, a fish eater with a neck as long as 1.3 metres (4.3 ft). In many respects its body structure resembled that of the much later plesiosaurs, but it was not as well adapted to an aquatic environment.

Once caught, few animals would be able to shake themselves free from the mouth of Nothosaurus. Trackways attributed, partly by process of elimination, to a nothosaur, that were reported from Yunnan, China in June 2014, were interpreted as the paddle impressions left as the animals dug into soft seabed with rowing motions of their paddles, churning up hidden benthic creatures that they snapped up. The skull was broad and flat, with long jaws, lined with needle teeth, it probably caught fish and other marine creatures. When swimming, Nothosaurus would use its tail, legs, and webbed feet to propel and steer it through the water. giganteus were larger, up to 5–7 metres (16–23 ft). It was about 4 metres (13 ft), with long, webbed toes and possibly a fin on its tail. Nothosaurus was a semi- oceanic animal which probably had a lifestyle similar to that of today's seals. It is the best known member of the nothosaur order. Nothosaurus ("false lizard", from the Ancient Greek nothos ( νόθος), "illegitimate", and sauros ( σαῦρος), "lizard") is an extinct genus of sauropterygian reptile from the Triassic period, approximately 240–210 million years ago, with fossils being distributed from North Africa and Europe to China.
