About Casatia

Casatia is an extinct genus of cetacean in the family Monodontidae, known from the Early Pliocene, approximately between 5.1 to 4.5 million years ago. The type species, C. thermophila, was described in 2019 from a partial skull found in Italy, representing the only known fossils of a monodontid from the Mediterranean Basin. Its closest living relatives are the narwhal and beluga, though the remains were found farther south than these species, supporting the hypothesis that monodontids evolved in warmer regions before adapting to cold water. Other partial indeterminate remains are known from the Kattendijk Formation of Belgium.
