==Discovery== thumb|left|P. portelli cast skeleton produced and distributed by Triebold Paleontology Incorporated In the 1990s, vertebrate fossils were found in lagoon deposits at Seven Rivers in Jamaica by Daryl Domning and colleagues. The site is rich in fossils, and yielded hundreds of bones of mainly aquatic vertebrates, a primitive rhinoceros, and possibly a primate. In 2001, Domning named Pezosiren portelli based on sirenian bones found at Seven Rivers.
