Evolución de los caracteres dentarios en el género Palaeomys (Mammalia: Rodentia)

Abstract

Variation in morphology of Palaeomys cheek teeth has been examined in respect of age classes and geological time. When the effects ofwear are taken into account, certain patterns dental variation are found to be restricted in time. The morphological and biometric changes in the fossil record shou/d be taken as evidence of certain patterns of evolution
