Brodiechelys brodiei
Taxonomy
Plesiochelys brodiei was named by Lydekker (1889). Its type specimen is BMNH R2643, a partial shell, and it is a 3D body fossil. Its type locality is Atherfield Point, Brighstone Bay, which is in a Barremian/Aptian terrestrial horizon in the Vectis Formation of the United Kingdom.
It was recombined as Brodiechelys brodiei by Milner (2011), Pérez-García (2012), Pérez-García and Murelaga (2013) and Pérez-García et al. (2014).

Diagnosis

|---|---|---|
| A. Pérez-García 2012 | Pancryptodiran turtle sharing the following character combination: oval, longer than wide, and relatively low shell; anterior margin of the carapace straight or slightly notched; dorsal surface of the vertebral and pleural scutes weakly sculptured by grooves radiating forwards; nuchal trapezoidal and wider than long; 7-9 neural plates; first neural or first pair of neurals rectangular, the following plates hexagonal, and the last neural or pair of neurals subpentagonal to subcircular; medial contact of the seventh or seventh and eighth pairs of costals; two suprapygals, the length of both plates being similar but the width of the second one greater than that of the first; 11 pairs of peripherals; posterior peripherals longer than anterior ones; absence of dorsal thickening of lateral edges in the anterior peripherals; medio-laterally expanded posterior peripherals; single cervical scute, more than four times wider than long; first vertebral wider than long, trapezoidal, with lateral margins divergent towards the anterior region; second to fifth vertebrals slightly wider than long; first vertebral slightly narrower than the second, and decreasing in width from second to fifth vertebrals; pleural scutes overlapping the medial half of the first peripheral plates and the medial third of the last peripherals, but marginals slightly overlapping the lateral margins of the second to fourth costal plates; marginal not overlapping the second suprapygal; absence of costal-peripheral and plastral fontanelles; osseous connection between carapace and plastron; posterior plastral lobe longer than the anterior one; rounded anterior lobe; distal region of the posterior lobe sub-perpendicular to the axial axis, lacking anal notch; entoplastron small, of similar length and width; contact between epiplastra and hyoplastra sub-perpendicular to the axial plane; hyoplastra longer than hypoplastra; absence of mesoplastra; postero-lateral expansion of the hypoplastra; undeveloped sinuosity in the medial sulcus of the plastron; presence of one pair of gular scutes, longer than the extragulars; gulars superimposed on the antero-medial region of the entoplastron; humeral-pectoral grooves situated far behind the posterior margin on the entoplastron; four inframarginals; anal scutes medially overlapping the hypoplastra or near the posterior region of this pair of plates. |
