Dental microwear

Dental microwear analysis is a method to infer diet and behavior in extinct animals, especially in fossil specimens.[1][2][3][4] Typically, the patterns of pits and scratches on the occlusal or buccal surface of the enamel are compared with patterns observed in extant species to infer ecological information.[5][6] Hard foods in particular can lead to distinctive patterns (although see below). Microwear can also be used for inferring behavior, especially those related to the non-masticatory use of teeth as 'tools'. Other uses include investigating weaning in past populations.[7] Methods used to collect data initially involved a microscope and manually collecting information on individual microwear features, but software to automatically collect data have improved markedly in recent years.[8]
