DESCRIPTION
m3 (MAB3)
The tooth is D-shaped in occlusal view and shows no reduction in its posterior part The anterolophid is long. The endolophid may be complete (1 out or 2) or not (1 out of 2). There is a small anterotropid, which may be connected (1 out of 2) or not (1 out of 2) to the endolophid. The centrolophid is short. There may be a centrotropid (1 out of 2) or not (1 out of 2), and the posterotropid is short. The posterolophid and the mesolophid have a low connection.
P4 ( MAB 3)
The tooh is rounded in occlusal view. The endoloph is complete. The anteroloph is short and isolated in the labial side. The protoloph and the metaloph are long, straight and isolated. The postcentroloph is long. The posteroloph is longer than the anteroloph and it is isolated labially.
M1 ( MAB 3)
The tooth is quadrate in occlusal view, with narrow crests and wide valleys. The anteroloph is medium in size and isolated. The protoloph and the metaloph are connected in the lingual side forming a V-shape. The precentroloph is shorter than the postcentroloph, and the first crest is of medium size. Both centrolophs are interconnected forming a Y-shape and connected to the metaloph. The posteroloph is of intermediate size, but shorter than the anteroloph, and the posteroloph is well connected in the lingual side and isolated in the labial side. The MAB 5 material has a more medial protoloph-metaloph connection, the centrolophs are not interconnected, and the posteroloph is shorter, lingually isolated and connected in the labial side.
M2 ( MAB 3)
The tooth is broken, but still shows a subquadrate outline in occlusal view, wide valleys and narrow crests. There are two centrolophs, the anterior one is shorter than the posterior one and they are connected forming a Y-shape. The postcentroloph almost reaches the lingual side of the tooth.
M3 ( MAB 5)
The tooth is trapezoid in occlusal view. The anteroloph is long. The endoloph is complete. The protoloph and the metaloph are independent. The precentroloph may be absent (1 out of 3); when present it is short and may be connected in the lingual side (2 out of 3). The postcentroloph is long and connected in the lingual side. The metatrope is present in two specimens. The posteroloph is short and isolated in the labial side. The labial cusps are better developed than the lingual ones.
REMARKS
The record of Prodryomys remmerti is restricted to its type locality of Blaquatére 1 ( Aguilar & Lazzari 2006). Therefore, the material here described constitutes the first discovery of this species in the Iberian Peninsula.
The material described here displays typical characteristics of the genus Prodryomys . These include longer posterior centrolophs, fine crests and wide valleys, although less than in P. satus , as well as a rounded outline and a V-shaped trigon. Morphologically, our material is similar but significantly larger than the one described by Aguilar & Lazzari (2006). It differs from P. satus in its morphology and from P. gregarius in its size. It is also smaller and less brachydont than P. brailloni ( Wu 1993; Daams 1999a; Aguilar & Lazzari 2006).
