Chelonides is a genus of lateJurassic turtle from marine deposits inLower Saxony, Germany.
The nameChelonides 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) fromHannover, northwestern Germany.[1] Later, Portis (1878) erected a second species,C. robusta, for elements of the shell (GZG 769–11 to 769–19). Hay (1905) consideredChelonides preoccupied without comment and erectedAnaphotidemys 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 nominalChelonides species as synonymous with the plesiochelyidPlesiochelys without justification. A 2017 overview of thalassochelydians, however, indicates thatChelonides is a valid genus of eurysternid, although,C. robusta is anomen dubium.[2][3]
