Although politically part of Puerto Rico, along with the islands of Mona and Monito, Desecheo is not geologically related to the main island. It is believed that the island has been isolated, at least, since the

Pliocene The Pliocene ( ; also Pleiocene) is the epoch in the geologic time scale that extends from 5.333 million to 2.58Rio Culebrinas formation which suggests that it was once connected to Puerto Rico.
