Abstract
The study of the remains of Nesophontes micrus Allen, 1917 and N. major Arredondo, 1970 from El Abrón Cave (Republic of Cuba, Pinar del Río Province, Late Pleistocene) allowed to establish for the first time anomalies of the dentition in Nesophontidae. Failures of eruption of teeth (impaction of I3 in N. micrus, retention or impaction of P2 in N. major), as well as malformations (aberrant I3 in N. micrus, P2 and P4 in N. major), are the developmental abnormalities. The absence of P2 and M2 in combination with reossification of their alveoli in N. major is caused by dental injuries and diseases.
