Chelone costata

Reptilia - Testudines - Cheloniidae

Taxonomy
Chelone costata was named by Owen (1853). Its type specimen is BMNH 2370, a partial shell (slab of sandstone showing the ventral surface of the anterior portion of the left side of the carapace), and it is a 3D body fossil. Its type locality is Tilgate Forest, Cuckfield, which is in a Valanginian terrestrial sandstone in the Tunbridge Wells Sand Formation of the United Kingdom.

It was recombined as Plesiochelys costata by Lydekker and Boulenger (1887); it was synonymized subjectively with Hylaeochelys belli by Delair (1958), Heinrich (1991), Milner (2011) and Pérez-García (2012).
