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 …

Fossil whale material from the Oligocene-aged marine beds underlying the region around
Charleston, South Carolina, has provided an unparalleled view of post-archaeocete …

Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter
feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological …

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 …

A previously undescribed new family of archaic fossil toothed mysticetes includes new three
species in two new genera of cetaceans from Late Oligocene deposits near Charleston …

As the largest known vertebrates of all time, mysticetes depend on keratinous sieves called
baleen to capture enough small prey to sustain their enormous size [1]. The origins of …

Although combined molecular and morphological analyses point to a late middle Eocene
(38–39 million years ago) origin for the clade Neoceti (Odontoceti, echolocating toothed …

Whales use baleen, a novel integumentary structure, to filter feed; filter feeding itself evolved
at least five times in tetrapod history but demonstrably only once in mammals [1]. Living …

The origin of baleen in mysticete whales represents a major transition in the phylogenetic
history of Cetacea. This key specialization, a keratinous sieve that enables filter-feeding …

Toothed mysticetes of the family Aetiocetidae from Oligocene rocks of the North Pacific play
a key role in interpretations of cetacean evolution because they are transitional in grade …
