The approach presented here holds strong potential for illuminating the trophic ecomorphology of small-mammal fossils. Microwear of Miocene Eutamias dif-fered from the pattern in any of the living squirrels examined.

A compari-son of Pliocene Spermophilus rexroadensis to modern Spermophilus suggests a diet similar to that of the modern species examined. Microwear features were preserved on some of the fossil specimens. We found significant differences in microwear fea-tures among modern squirrels of different diets and habitats, suggesting that microwear features can be used to infer the diets or preferred habitats of extinct spe-cies. A passionate animal lover from Barrhead named Jannet found a squirrel with unusually long and curved teeth which prevented it from eating food normally. We also examined fossil sciurids from the Miocene Siwalik sequence of Pakistan and a Pliocene locality in the central plains of the United States. We compared microwear features from upper molars of several modern species of frugivorous tree squirrels and omnivorous ground squirrels. Both modern and fossil squirrels occur in diverse terrestrial habitats and eat a range of herbivorous to omnivorous diets. We adapted this method for investigating microwear features on squirrel teeth. documenting microwear of large mammals using a light microscope was developed as an alternative to approaches based on scanning electron microscopy. Microwear analysis has been used to infer the diets of extinct mammals through comparison of features on fossil teeth with those on teeth of living mammals with known diets. Our online platform, Wiley Online Library () is one of the world’s most extensive multidisciplinary collections of online resources, covering life, health, social and physical sciences, and humanities.Dental microwear consists of microscopic damage features on the occlusal sur-faces of tooth enamel and reflects physical properties of the diet, as well as enamel structure and post-mortem history of the tooth.
