Species
The type species, ''Atlanticetus patulus'' was originally described as ''Aglaocetus patulus'' from the Calvert Formation by Remington Kellogg in 1968.[R. Kellogg. 1968. "A sharp-nosed cetothere from the Miocene Calvert". ''Proceedings of the United States National Museum'' 247(7):163-173.] However, it was recovered by Bisconti et al. (2013) in a different phylogenetic position than the ''Aglaocetus
''Aglaocetus'' is a genus of extinct baleen whales known from the Miocene of Patagonia, the US Eastern Seaboard, Japan and the Low Countries. It was once considered a member of Cetotheriidae along with many other putative cetotheres, but was rece ...
'' type species ''Aglaocetus moreni''.[M. Bisconti, O. Lambert, and M. Bosselaers. 2013. "Taxonomic revision of ''Isocetus depauwi'' (Mammalia, Cetacea, Mysticeti) and the phylogenetic relationships of archaic 'cetothere' mysticetes". ''Palaeontology'' 56(1):95-127.] 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.[Bisconti, M., Damarco, P., Mao, S., Pavia, M. and Carnevale, G. (2020).
