Chelonides
Chelonides is a genus of late Jurassic turtle from marine deposits in Lower Saxony, Germany. Taxonomy. The name "Chelonides wittei" was coined by Maack (1869) for a partial shell (GZG 773–1) a partial skull (GZG 773–2), and isolated shell and girdle elements (GZG 773–3 to 773–17) from Hannover, northwestern Germany. Later, Portis (1878) erected a second species, "C. robusta", for elements of the shell (GZG 769–11 to 769–19). Hay (1905) considered "Chelonides" preoccupied without comment and erected "Anaphotidemys" as a replacement. Kuhn (1964) mistakenly considered the genus preoccupied by Chelonides Boisduval, 1840, a tribe of nocturnal lepidopterans. In their  overview of Upper Jurassic and Early Cretaceous turtles from northwestern Germany, Karl et al. (2007) treated the two nominal "Chelonides" species as synonymous with the plesiochelyid "Plesiochelys" without justification. A 2017 overview of thalassochelydians, however, indicates that "Chelonides" is a valid genus of eurysternid, although, "C. robusta" is a "nomen dubium".
