LOCALITY. — CBR0B.

DESCRIPTION

m1 (CBR0B)

An extremely hypsodont broken tooth. The centrolophids are absent. The mesolophid and the posterolophid are long and low-connected on the lingual side. The labial cuspids are more developed than the lingual ones.

m2 ( CBR 0B)

The tooth is subquadrangular in outline and extremely hypsodont. The anterolophid is short and connected to the endolophid. The metalophid is long and curved, with a low contact with the anteroconid. The centrolophids are absent. The mesolophid and the posterolophid are long and low-connected on the lingual side. The labial cuspids are more developed than the lingual cuspids.

REMARKS

The genus Armantomys was considered endemic to the Iberian Peninsula, but has also been found in the French locality of Liet ( Daams 1990, Duranthon & Cahuzac 1997). This genus is recorded from the Oligocene (MP29) at the Parrales site (Loranca Basin) to the Middle Miocene (MN7/8) in the localities of Escobosa de Calatañazor, Soria and Alcocer 2 (Calatayud-Montalbán Basin) ( López-Martínez et al. 1977; Daams 1990; Álvarez-Sierra et al. 1999). Armantomys is characterised by its high degree of hypsodoncy. The absence of centrolophids distinguishes this genus from its ancestor Praearmantomys ( Daams 1990) .

The remains of this species in the Ribesalbes-Alcora Basin are very scarce, with only two teeth found in CBR 0B. These teeth are smaller than in Armantomys tricristatus López-Martínez, Benito & García, 1977 , but larger than in the smaller-sized species Armantomys jasperi Daams, 1990 , Armantomys parsani Daams, 1990 , Armantomys daamsi de Visser, 1991 , and Armantomys bijmai (Lacomba & Martínez-Salanova, 1988) . On the other hand, they are similar to those of A. aragonensis . Morphologically, the material from this basin is also like that of A. aragonensis from the MN4 of the Calatayud-Montalbán Basin and from Montalvos 2 from the Teruel Basin ( Daams 1990; Hordijk et al. 2015). The presence of a mesolophid and a lower or middle posterolophid connected to the entoconidare characteristic of this species, which allows us to classify it as A. aragonensis .
