Casatia is a genus of extinctcetacean from theEarly Pliocene, approximately between 5.1 and 4.5 million years ago. The genus contains a single species,C. thermophila. It was described from a partialskull. Its closest relatives are thenarwhal andbeluga (white whale), yet the remains were found farther south than its relatives, supporting the theory thatmonodontids evolved from warm water genera before becoming adapted to cold water.[citation needed]

Fossils were discovered in Italy and are the first and only fossils of amonodontid from theMediterranean Basin known. Fossils of the genus were also found near fossils of the modernbull andtiger sharks as well as many extinct marine mammals, such as the sirenianMetaxytherium subapenninum.[1]
