Hydration affects the physical and mechanical properties of baleen tissue [PDF]
Royal Society Open Science, 2016 Baleen, an anisotropic oral filtering tissue found only in the mouth of mysticete whales and made solely of alpha-keratin, exhibits markedly differing physical and mechanical properties between dried or (as in life) hydrated states.

A new archaic baleen whale Toipahautea waitaki (early Late Oligocene, New Zealand) and the origins of crown Mysticeti [PDF]
Royal Society Open Science, 2018 A new genus and species of extinct baleen whale †Toipahautea waitaki (Late Oligocene, New Zealand) is based on a skull and associated bones, from the lower Kokoamu Greensand, about 27.5 Ma (local upper Whaingaroan Stage, early Chattian).

Diversity, 2022 A review of the morphological patterns exhibited by all the main radiations of mysticete (baleen whale) cetaceans provided a broad assessment of the fundamental morphological transformations that occurred in the transition to the Mysticeti clade.

Detection of Mysticete Calls: a Sparse Representation-Based Approach
, 2017 This paper presents a methodology for automatically detecting mysticete calls. This methodology relies on sparse representations of these calls combined with a detection metric that explicitly takes into account the possible presence of interfering ...

Like phoenix from the ashes: How modern baleen whales arose from a fossil “dark age” [PDF]
Acta Palaeontologica Polonica, 2019 The evolution of baleen whales (Mysticeti), the largest animals on Earth, was punctuated by a pivotal turnover event. Following their emergence around 36 million years (Ma), mysticetes diversified into a disparate range of toothed and toothless species ...

New specimens and species of the Oligocene toothed baleen whale Coronodon from South Carolina and the origin of Neoceti [PDF]
PeerJ, 2023 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 early diverging tooth-bearing mysticetes highlighting the transition ...

Zoological Journal of the Linnean Society, 2021 Extant baleen whales (Mysticeti) have a deciduous foetal dentition, but are edentulous at birth. Fossils reveal that the earliest mysticetes possessed an adult dentition.

Coexistence of Oligocene toothed and baleen-assisted mysticetes in the northwestern Pacific [PDF]
Fossil RecordOligocene mysticetes display an unparalleled diversity and morphological disparity in the evolutionary history of Mysticeti. However, their paleoecological aspects, such as the patterns of coexistence of different morphotypes, remain poorly explored ...
