Bony outgrowths on the jaws of an extinct sperm whale support macroraptorial feeding in several stem physeteroids

Lambert, Olivier; Bianucci, Giovanni; Beatty, Brian L. (2014)

Several extinct sperm whales (stem Physeteroidea) were recently proposed to differ markedly in their feeding ecology from the suction-feeding modern sperm whales Kogia and Physeter. Based on cranial, mandibular, and dental ...
Convergence and constraint in the cranial evolution of mosasaurid reptiles and early cetaceans

Bennion, Rebecca F.; MacLaren, Jamie A.; Coombs, Ellen J.; Marx, Felix G.; Lambert, Olivier; Fischer, Valentin (2022)

The repeated return of tetrapods to aquatic life provides some of the best-known examples of convergent evolution. One comparison that has received relatively little focus is that of mosasaurids (a group of Late Cretaceous ...
Ecomorphology of toothed whales (Cetacea, Odontoceti) as revealed by 3D skull geometry

Vicari, Deborah; McGowen, Michael R.; Lambert, Olivier; Brown, Richard P.; Bianucci, Giovanni; Sabin, Richard C.; Meloro, Carlo (2023)

Extant odontocetes (toothed whales) exhibit differences in body size and brain mass, biosonar mode, feeding strategies, and diving and habitat adaptations. Strong selective pressures associated with these factors have ...
<I>Yaquinacetus meadi</I>, a new latest Oligocene early Miocene dolphin (Cetacea, Odontoceti, Squaloziphiidae, fam. nov.) from the Nye Mudstone (Oregon, U.S.A.)

Lambert, Olivier; Godfrey, Stephen J.; Fitzgerald, Erich M. G. (2018)

Represented by a nearly complete cranium with associated mandible, teeth, and vertebrae, Yaquinacetus meadi is a new genus and species of archaic homodont odontocete from the latest Oligocene early Miocene (24 19.2 Ma) of ...
A new inioid (Cetacea, Odontoceti, Delphinida) from the Miocene of Peru and the origin of modern dolphin and porpoise families

Lambert, Olivier; Bianucci, Giovanni; Urbina, Mario; Geisler, Jonathan H. (2017)

In this paper we describe Brujadelphis ankylorostris gen. nov., sp. nov., a new delphinidan (Cetacea, Odontoceti, Delphinida), based on a well-preserved skull with ear bones, associated mandibles, most of the teeth in situ ...
A new physeteroid from the late Miocene of Peru expands the diversity of extinct dwarf and pygmy sperm whales (Cetacea: Odontoceti: Kogiidae)

Collareta, Alberto; Lambert, Olivier; de Muizon, Christian; Benites Palomino, Aldo Marcelo; Urbina, Mario; Bianucci, Giovanni (2020)

Nowadays, the odontocete family Kogiidae is monotypic and only includes two species of diminutive relatives of the great sperm whale Physeter Linnaeus, 1758. Conversely, a growing body of extinct species indicates that ...
Plasticity and Convergence in the Evolution of Short-Necked Plesiosaurs

Fischer, Valentin; Benson, Roger B. J.; Zverkov, Nikolay G.; Soul, Laura C.; Arkhangelsky, Maxim S.; Lambert, Olivier; Stenshin, Ilya M.; Uspensky, Gleb N.; Druckenmiller, Patrick S. (2017)

Plesiosaurs were the longest-surviving group of secondarily marine tetrapods, comparable in diversity to today's cetaceans. During their long evolutionary history, which spanned the Jurassic and the Cretaceous (201 to ...
