Micromys
[1] Fossils of Micromys date back to the Late Miocene and include at least 10 extinct species, which form several lineages.Distribution ranges from northwest Spain through most of Europe, across Siberia to Korea, north to about 65 degrees in Russia, south to the northern edge of Mongolia.Originally, these mice lived in humid regions with high, long-lasting grasses growing near rivers, ponds, and lakes.As with other members of its subfamily, M. minutus has moderately low crowned teeth with rounded cusps on the biting surface arranged in three longitudinal rows.The auditory bullae are large, and it is thought that the size of these resonating chambers enables the mouse to detect low frequency sounds carried over great distances, and thus be better able to escape predation.
