Congratulations to our colleague Olivier Lambert for the earliest Mysticete!

Lambert et al. describe a new toothed cetacean from the late Eocene of Peru. Being the oldest known baleen whale relative (Mysticeti), its skeletal morphology provides crucial information about the archaeocete-neocete transition, suggesting a specialization toward suction and possibly benthic feedin...

For today's , enjoy one of the rarest whales on earth!

Students captured images of the True's beaked cetacean, which spends about 92 percent of its time below the sea's surface.

More beaked whales + more South American fossils = win!

A fossil skull of a beaked whale was newly collected by a manned submersible from the São Paulo Ridge of the Atlantic floor about 2900 m deep off the coast of Brazil. It was found in the middle of the manganese nodules on the seafloor. The whale fossil can be dated sometime between the middle Miocen...

And something a little more appropriate for this . Major congrats to Travis Park and coauthors for this one!

Living baleen whales (mysticetes) produce and hear the lowest-frequency (infrasonic) sounds among mammals. There is currently debate over whether the ancestor of crown cetaceans (Neoceti) was able to detect low frequencies. However, the lack of information on the most archaic fossil mysticetes has p...

New developmental mechanisms for the Mammalian middle ear? Why yes, we're interested!

http://rspb.royalsocietypublishing.org/content/284/1848/20162416?etoc

Multiple mammalian lineages independently evolved a definitive mammalian middle ear (DMME) through breakdown of Meckel's cartilage (MC). However, the cellular and molecular drivers of this evolutionary transition remain unknown for most mammal groups. Here, we identify such drivers in the living mar...

Nice article on the Smithsonian's National Museum of Natural History's impressive fossil and extant whale collection. The video features Smithsonian Paleobiology Nick Pyenson talking about the collection, its history and its uniqueness

How 20th century whaling turned the abundance of the Antarctic into a killing field, and the NMNH warehouse into “a collection that cannot be made again."

Then a shoutout to our colleague Olivier Lambert for their new beaked whales from South America!

The Ziphiidae (beaked whales) represent a large group of open-ocean odontocetes (toothed cetaceans), whose elusive and deep diving behavior prevents direct observation in their natural habitat. Despite their generally large body size, broad geographical distribution, and high species number, ziphiid...

Check out the great work being done by our colleagues at the Pyenson lab at the Smithsonian's National Museum of Natural History, and by our very own Carlos Mauricio Peredo, in this Facebook live video by PBS NewsHour. The video features Arktocara yakataga, the new dolphin described by Alex Boersma and Nick Pyenson, specimens that Carlos is working on, and other fossils in the collections.
