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 recently recognized as representing a distinct family from true Cetotheriidae. Species There are three currently recognized valid species: ''Aglaocetus moreni'', ''A. latifrons'', and ''A. rotundus''. The type species, ''Aglaocetus moreni'', was originally described as a species of ''Cetotherium'', but later recognized as generically distinct from the latter. ''"Aglaocetus" patulus'', described from the Calvert Formation by Remington Kellogg in 1968, was recovered by Bisconti et al. (2013) in a different phylogenetic position than the ''Aglaocetus'' type species. In 2020, ''A. patulus'' was renamed ''Atlanticetus''.Bisconti, M., Damarco, P., Mao, S., Pavia, M. and Carnevale, G.

Gaimán Formation
The Gaiman Formation (), in older literature also referred to as Patagonian Marine Formation (, ''Patagoniense''), is a list of fossiliferous stratigraphic units in Argentina, fossiliferous geologic Formation (geology), formation of the Peninsula Valdés Basin in the eastern Chubut Province of northwestern Patagonia, eastern Argentina. The thick formation overlies the Sarmiento Formation and is overlain by the Puerto Madryn Formation and comprises grey and white tuffaceous mudstones and sandstones, deposited in a shallow marine depositional environment, environment. The Gaiman Formation has provided fossils of many extinct penguins, among which five species in the genus ''Palaeospheniscus'', as well as whales and dolphins, most notably ''Aondelphis, Aondelphis talen'', ''Prosqualodon, Prosqualodon australis'', ''Idiorophus, Idiorophus patagonicus'' and ''Argyrocetus, Argyrocetus patagonicus'', indeterminate seal and turtle fossils, shark and other fossils.
