Peredo, Carlos Mauricio; Pyenson, Nicholas D.; Uhen, Mark D.; Marshall, Christopher D. (2017)The evolution of filter feeding in baleen whales (Mysticeti) facilitated a wide range of ecological diversity and extreme gigantism. The innovation of filter feeding evolved in a shift from a mineralized upper and lower ...

Gutstein, Carolina Simon; Cozzuol, Mario Alberto; Pyenson, Nicholas D. (2014)"River dolphins" are a paraphyletic group of toothed whales (Odontoceti) that represent independent secondary invasions of freshwater habitats. Different "river dolphin" lineages display suites of convergent morphological ...

Boersma, Alexandra T.; Pyenson, Nicholas D. (2016)The diversification of crown cetacean lineages (i.e., crown Odontoceti and crown Mysticeti) occurred throughout the Oligocene, but it remains an ongoing challenge to resolve the phylogenetic pattern of their origins, ...

Savoca, Matthew S.; Czapanskiy, Max F.; Kahane-Rapport, Shirel R.; Gough, William T.; Fahlbusch, James A.; Bierlich, K. C.; Segre, Paolo S.; Di Clemente, Jacopo; Penry, Gwenith S.; Wiley, David N.; Calambokidis, John; Nowacek, Douglas P.; Johnston, David W.; Pyenson, Nicholas D.; Friedlaender, Ari S.; Hazen, Elliott L.; Goldbogen, Jeremy A. (2021)A combination of 3D whale locations and acoustic measurements of prey density is used here to show that whales' consumption of krill is several times larger than often thought. Baleen whales influence their ecosystems ...

Shipps, B. K.; Peredo, Carlos Mauricio; Pyenson, Nicholas D. (2019)Baleen whales (mysticetes) lack teeth as adults and instead filter feed using keratinous baleen plates. They do not echolocate with ultrasonic frequencies like toothed whales but are instead known for infrasonic acoustics. ...

Mccurry, Matthew R.; Marx, Felix G.; Evans, Alistair R.; Park, Travis; Pyenson, Nicholas D.; Kohno, Naoki; Castiglione, Silvia; Fitzgerald, Erich M. G. (2021)Cetaceans (whales and dolphins) have some of the largest and most complex brains in the animal kingdom. When and why this trait evolved remains controversial, with proposed drivers ranging from echolocation to foraging ...

Peredo, Carlos Mauricio; Peredo, Julio S.; Pyenson, Nicholas D. (2018)The fossil record of mammal dentition provides crucial insight into key ecological and functional transitions throughout mammalian evolutionary history. For cetaceans, both extant clades differ markedly from their stem ...

Pyenson, Nicholas D.; Goldbogen, Jeremy A.; Vogl, A. Wayne; Szathmary, Gabor; Drake, Richard L.; Shadwick, Robert E. (2012)Top ocean predators have evolved multiple solutions to the challenges of feeding in the water1, 2, 3. At the largest scale, rorqual whales (Balaenopteridae) engulf and filter prey-laden water by lunge feeding4, a strategy ...

Uhen, M. D.; Pyenson, Nicholas D. (2007)The number of cetacean genera varied greatly over their evolutionary history. Cetaceans originated in the Eocene and then rapidly diversified, reaching around 30 genera during the Middle Eocene. The number of genera crashed ...
