“…However, the lack of diagnostic criteria between closely related taxa raises the question of how to use morphological characters for species identification adequately (Nadachowski 1984;Kochev 1986;Chaline et al 1989;Smirnov et al 1997;Carrasco 2000, Semken & Wallace 2002Markova & Borodin 2005;Borodin 2009). Sibling species that are extremely similar in appearance but are nonetheless reproductively isolated appear to be the most problematic to identify in the fossil record.…”

“…It is often claimed that a multivariate morphological approach is applicable to the differentiation of closely related species of micromammals in the fossil record (Chaline et al 1989;Smirnov et al 1997;Leroy et al 2004;Polly & Head 2004;Tobin 2004;Wallace 2006;McGuire 2009). However, the taxonomic inferences from multivariate morphological analyses of fossil data have never been tested using any independent technique for taxonomic identification.…”

“…Occurrences of M. schisticolor have already been suggested for European Early and Middle Pleistocene sites at Boxgrove (England;Roberts and Parfitt, 1999) and Vergranne (France; Chaline et al, 1989) and suspicions of its presence (records of Myopus/Lemmus) have been raised in Chlum-4 (Czech Republic; Kowalski, 2001), Nyaravai-2 (Lithuania; Kowalski, 2001) and Sudmer-Berg 2 (Germany; von Koenigswald, 1972). In general, these suspicions are based on both the morphology of the teeth and on the faunal associations, which are characteristic of a forest environment.…”

Lemmus and Myopus are two lemming species with distinct habitat requirements but which show very similar dental morphologies. They are thus extremely difficult to distinguish from one another in the fossil record on the basis of their dental remains, leading to poor understanding of the palaeobiogeographical evolution of Myopus as well as inaccurate palaeoenvrionmental reconstructions. Currently, the presence of Myopus in the fossil register from the Pleistocene is still debated and no firm occurrence of this lemming in western Europe has yet been confirmed for the Late Pleistocene. In this paper, we used geometric morphometrics on modern material to establish morphological differences between Lemmus and Myopus teeth (first lower and third upper molars). Morphological data were then used to build a robust linear discriminant model able to confidently classify isolated teeth of these two genera, and finally, linear discriminant models were used on fossil remains of Lemmus/Myopus from two Late Pleistocene archaeological/palaeontological sites (Grotte des Gorges and Gully Cave). This study demonstrates, for the first time, the presence of Myopus schisticolor in west European Late Pleistocene sites between the end of Marine Isotope Stage 3 and the beginning of the Holocene, during climatic events that favoured the development of taiga forest of birch and pine in these regions.

In this study it is demonstrated that food-specialization of different species of voles and lemmings is reflected in their dental pattems. The subfamily of Arvicolinae was chosen because the basic structure of the occlusal pattems of their molars is very stereotypical and thus their modifications can be attributed to differences in function. The properties of their M2 occlusal patterns are expressed by structural parameters such as pattern density, relative enamel surface and orientation of the enamel edges. Marked differences were found between grass-and moss-feeding species on the one hand as well as root-feeding species on the other. Differences of construction of walls of plant cells of the ¡ tissues determine the kind of fooddisintegration. The grass-and moss-feeders have evolved a dentition with high pattern density, low relative enamel surface anda high degree of o¡ of the enamel bands. The root-feeders have a dentition with low pattern density, high relative enamel surface anda low degree of orientation. Species, which often feed on seeds or have a wide range of diet, are located between them.
