Atlanticetus

Atlanticetus is a genus of extinct baleen whales known from the Early Miocene of Italy and the US Eastern Seaboard.

Species
The type species, Atlanticetus patulus was originally described as Aglaocetus patulus from the Calvert Formation by Remington Kellogg in 1968. However, it was recovered by Bisconti et al. (2013) in a different phylogenetic position than the Aglaocetus type species Aglaocetus moreni. In 2020, A. patulus was made the type species of a new genus Atlanticetus. A second species, A. lavei, is known from the early Miocene Gruppo Pietra da Cantoni of Piedmont, Italy.
