The extant diversity and rich fossil record of cetaceans provides an extraordinary
evolutionary context for investigating the relationship between form, function and ecology …

The evolution of cetaceans is one of the best examples of macroevolution documented from
the fossil record. While ecological transitions dominate each phase of cetacean history, this …

The evolution of cetaceans (whales and dolphins) represents one of the most extreme
adaptive transitions known, from terrestrial mammals to a highly specialized aquatic …

Baleen whales (Mysticeti) are the largest animals on Earth, thanks to their ability to filter
huge volumes of small prey from seawater. Mysticetes appeared during the Late Eocene …

Phylogenetic trees provide a powerful framework for testing macroevolutionary hypotheses,
but it is becoming increasingly apparent that inferences derived from extant species alone …

Baleen whales (Mysticeti) are gigantic filter-feeding cetaceans possessing the unique soft
tissue structure baleen and lacking adult teeth; Oligocene fossils have revealed a wealth of …

Background Unlike most mammals, toothed whale (Odontoceti) skulls lack symmetry in the
nasal and facial (nasofacial) region. This asymmetry is hypothesised to relate to …

Cynthiacetus peruvianus is a Dorudon-like basilosaurid (Cetacea, Basilosauridae), being
one of the largest members of the family. The holotype of this species is a sub-complete …

Cetaceans use sound for communication, navigation and finding prey. Most extant
odontocetes produce broadband (BB) biosonar clicks covering frequency ranges from tens …

Mysticeti (baleen whales) and Odontoceti (toothed whales) today greatly differ in their
hearing abilities: Mysticeti are presumed to be sensitive to infrasonic noises [1–3], whereas …
