Alagomyidae is a family ofrodents known from the latePaleocene and earlyEocene ofAsia andNorth America (McKenna and Bell, 1997). Alagomyids have been identified as the mostbasal rodents, lying outside the common ancestry of living forms (Meng et al., 1994). Because of theirphylogenetic position and their conservativedental morphology, alagomyids have played a key role in investigations of the origins and relationships of rodents (Meng et al., 1994; Meng and Wyss, 2001).
