Abstract
The presence of deciduous premolars and erupting C1, P2, P4, I1, I2, I3, P2, and P4 in Nesophontidae is established for the first time on the fossil remains of Nesophontes major Arredondo, 1970, and N. micrus Allen, 1917 from El Abrón Cave (Republic of Cuba, Pinar del Río Province, Late Pleistocene). During ontogenesis, the replacement of teeth (except P1 and P1) occurred after the molar eruption, but before the animal reached adult size. By the dental replacement pattern nesophontids differ from most members of Lipotyphla and are close to Solenodontidae.

古巴更新世 Nesophontidae (Lipotyphla, Mammalia) 的牙齿置换
摘要
Nesophontidae的落叶前磨牙和喷发的 C 1、P 2、P 4、I 1、I 2、I 3、P 2和 P 4 的存在是第一次在Nesophontes major Arredondo的化石遗骸上确定,1970,和N. micrus Allen,1917 年来自 El Abrón Cave(古巴共和国,Pinar del Río 省,晚更新世)。在个体发育过程中,牙齿的更换(除了 P 1和 P 1) 发生在磨牙萌出之后,但在动物达到成年尺寸之前。根据牙齿更换模式,新翅目与大多数 Lipotyphla 成员不同,并且接近于 Solenodontidae。
