Borealodon osedax, a new stem mysticete (Mammalia, Cetacea) from the Oligocene of Washington State and its implications for fossil whale-fall communities [PDF]

open access: yesRoyal Society Open Science, 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.

Neurovascular evidence for a co-occurrence of teeth and baleen in an Oligocene mysticete and the transition to filter-feeding in baleen whales [PDF]

open access: yesZoological 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.

Alveoli, teeth, and tooth loss: Understanding the homology of internal mandibular structures in mysticete cetaceans. [PDF]

open access: yesPLoS ONE, 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 dentition in stem mysticetes to ...

Validation of a computational model of bone conduction sound reception in mysticetes. [PDF]

open access: yesPLoS ONE
Computational models serve as useful complements to physical experiments, but they require validation to build confidence in their applicability. This study outlines the validation of biomechanical models for mysticete sound reception, specifically using

Baleen boom and bust: a synthesis of mysticete phylogeny, diversity and disparity [PDF]

open access: yesRoyal Society Open Science, 2015
A new, fully dated total-evidence phylogeny of baleen whales (Mysticeti) shows that evolutionary phases correlate strongly with Caenozoic modernization of the oceans and climates, implying a major role for bottom-up physical drivers.

Humpback whale masked hearing thresholds in noise measured with modified behavioral observation audiometry [PDF]

open access: yesCommunications Biology
Audiograms are available for multiple species of odontocetes (toothed whales). However, there are no empirically measured audiograms for any mysticete (baleen whale) meaning their hearing sensitivity is inferred.

Strontium in fin whale baleen: A potential tracer of mysticete movements across the oceans?

open access: yesScience of the Total Environment, 2019
Strontium is a metal broadly distributed in oceanic waters, where its concentrations follow gradients mainly driven by oceanographic and biological factors.

Utilizing long-term opportunistic sightings records to document spatio-temporal shifts in mysticete presence and use in the Central Salish Sea

open access: yesFrontiers in Conservation Science
The Salish Sea supports several baleen whale species, including humpback (Megaptera novaeangliae), gray (Eschrichtius robustus) and minke whales (Balaenoptera acutorostrata).

Gigantic mysticete predators roamed the Eocene Southern Ocean [PDF]

open access: yesAntarctic Science, 2019
Modern baleen whales (Mysticeti), the largest animals on Earth, arose from small ancestors around 36.4 million years ago (Ma). True gigantism is thought to have arisen late in mysticete history, with species exceeding 10 m unknown prior to 8 Ma.

New records of odontocete and mysticete predation by orcas in the Humboldt current system, South Pacific Ocean

open access: yesFrontiers in Marine Science
Orcas (Orcinus orca) are the top marine predators of the ocean, targeting multiple taxa including teleost fishes, elasmobranchs, seabirds, sea turtles, pinnipeds, odontocetes and other large cetaceans.
