The Caribbean region is home to two unique families of the mammalian order Eulipotyphla (incorporating the now defunct order Soricomorpha), which also includes the hedgehogs, gymnures shrews, moles and desmans.
[2] DNA evidence suggests that solenodons are a sister group to a clade of shrews, moles, and erinaceids, with a molecular clock, providing evidence that the split from the other families occurred in the Cretaceous period, late in the Mesozoic era.
Isla de la Juventud is a large island south of Cuba.
Two extinct undescribed species of Nesophontes are known from several cave deposits on the Cayman Islands, a British archipelago south of Cuba.
[12] In the youngest layers of several deposits, Nesophontes is found together with introduced Rattus, indicating that its extinction occurred relatively recently.
