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 for a partial shell a partial skull, and isolated shell and girdle elements from Hannover, northwestern Germany. Later, Portis erected a second species, C. robusta, for elements of the shell. Hay considered Chelonides preoccupied without comment and erected Anaphotidemys as a replacement. Kuhn 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. 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.
