A new genus and species of arvicolid rodent (Mammalia) from the early Pleistocene of Spain

Abstract

In this paper, a new genus and species of arvicolid rodent is described from the late early Pleistocene levels of the sections of Fuente Nueva 3 (Guadix-Baza Basin, Granada, southern Iberian Peninsula), and Quibas (Murcia, southeastern Iberian Peninsula). The majority of Manchenomys n. gen. molars lacks roots, and the morphology of the first lower molar (m1) is simple, with a short and rounded anteroconid complex and widely confluent triangles four and five (T4 and T5) fields.
