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.

摘要

对来自 El Abrón Cave（古巴共和国，Pinar del Río 省，晚更新世）的Nesophontes micrus Allen, 1917 和N. Major Arredondo，1970的遗骸的研究首次允许建立 Nesophontidae 的牙列异常。牙齿萌出（第I嵌塞故障₃中N. Micrus有限公司，保留或P的嵌塞₂中N.主要），以及畸形（异常我₃中N. Micrus有限公司，P ₂和P ₄中N.主要） ，是发育异常。P ₂和 M ₂的缺失结合他们在 N 中的肺泡的再骨化。主要是由牙齿损伤和疾病引起的。
