Baleen whales, or mysticetes, include the largest vertebrates to have ever evolved. Their gigantism, evolutionary success, and ecological diversity have been linked to filter feeding. Mysticetes filter feed using elaborate keratinous baleen plates, which grow from the palate and allow them to strain large quantities of prey out of the water. While the earliest mysticetes retained the adult, mineralized teeth present in ancestral whales, all species of living baleen whales lack teeth and instead…

The Origin of Filter Feeding in Whales
Prenatal developmental sequence of the skull of minke whales and its implications for the evolution of mysticetes and the teeth‐to‐baleen transition
This work presents the first detailed description of prenatal specimens of minke whales, focusing on the skull anatomy and tooth germ development, resorption, and baleen growth, and presents comprehensive hypotheses to explain the influence of developmental processes on the evolution of skull morphology and feeding adaptations of mysticetes.
Morphological variation of the relictual alveolar structures in the mandibles of baleen whales
Living baleen whales (mysticetes) are bulk filter feeders that use keratinous baleen plates to filter food from prey laden water. Extant mysticetes are born entirely edentulous, though they possess
Convergence on dental simplification in the evolution of whales
Abstract. The fossil record of mammal dentition provides crucial insight into key ecological and functional transitions throughout mammalian evolutionary history. For cetaceans, both extant clades
Anatomical, ontogenetic, and genomic homologies guide reconstructions of the teeth-to-baleen transition in mysticete whales
Review and meta-analysis of available data suggest that the teeth-to-baleen transition in Mysticeti ranks among the best characterized macroevolutionary shifts due to the diversity of data from the genome, the fossil record, comparative anatomy, and ontogeny that directly bears on this remarkable evolutionary transformation.
Lateral palatal foramina do not indicate baleen in fossil whales
Today’s mysticetes filter-feed using baleen, a novel integumentary structure with no apparent homolog in any living mammal. The origins of filter-feeding and baleen can be informed by the fossil
Prenatal Development of the Humpback Whale: Growth Rate, Tooth Loss and Skull Shape Changes in an Evolutionary Framework
This developmental sequence confirms that the tooth‐to‐baleen transition occurs in the last one‐third of gestation, and finds similarities in the ossification patterns of the humpback and other cetaceans (dolphins), but there appear to be major differences when comparing them to terrestrial artiodactyls.
The evolution of foraging capacity and gigantism in cetaceans
Cetaceans have evolved specialized foraging mechanisms and extremely large body size to exploit unique ecological niches in the ocean.
Borealodon osedax, a new stem mysticete (Mammalia, Cetacea) from the Oligocene of Washington State and its implications for fossil whale-fall communities
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


Morphological and molecular evidence for a stepwise evolutionary transition from teeth to baleen in mysticete whales.
The dramatic transformation in mysticete feeding anatomy documents an apparently rare, stepwise mode of evolution in which a composite phenotype bridged the gap between primitive and derived morphologies; a combination of fossil and molecular evidence provides a multifaceted record of this macroevolutionary pattern.

The phylogenetic context of the new whale indicates that basal mysticetes were macrophagous predators that did not employ filter- feeding or echolocation, and that the evolution of characters associated with bulk filter-feeding was gradual.
From Teeth to Baleen and Raptorial to Bulk Filter Feeding in Mysticete Cetaceans: The Role of Paleontological, Genetic, and Geochemical Data in Feeding Evolution and Ecology.
Supporting this step-wise evolutionary hypothesis, evidence from stable isotopes show how changes in dental chemistry in early toothed mysticetes tracked the changes in diet and environment and genetic mutations and the possession of dental pseudogenes in extant baleen whales support a toOThed ancestry for mysticete.
Pseudogenization of the tooth gene enamelysin (MMP20) in the common ancestor of extant baleen whales
Genomic and palaeontological data now provide congruent support for the loss of enamel-capped teeth on the common ancestral branch of crown-group mysticetes, and support the hypothesis that the only unique, non-overlapping function of the MMP20 gene is in enamel formation.
Evolutionary aspects of the development of teeth and baleen in the bowhead whale
The development of teeth and baleen in bowhead whale fetuses is investigated using histological and immunohistochemical evidence and it is proposed that the signaling cascade that forms teeth in most mammals has been exapted to be involved in balean plate ontogeny in mysticetes.
Piscivory in a Miocene Cetotheriidae of Peru: first record of fossilized stomach content for an extinct baleen-bearing whale
This fossil record corresponds to one of the geologically oldest records of Sardinops worldwide, occurring near the Tortonian peak of oceanic primary productivity and cooling phase, and evokes a link between the rise of Cetotheriidae; the setup of modern coastal upwelling systems; and the radiation of epipelagic, small-sized, schooling clupeiform fish in such highly productive environments.
A new Early Oligocene toothed ‘baleen’ whale (Mysticeti: Aetiocetidae) from western North America: one of the oldest and the smallest
It is proposed that aetiocetids were suction-assisted raptorial feeders and interpret this strategy as a crucial, intermediary step, enabling the transition from raptorial to filter feeding, leading to all toothed mysticetes, and possibly even baleen whales as a whole.
Skull anatomy of the Oligocene toothed mysticete Aetioceus weltoni (Mammalia; Cetacea): implications for mysticete evolution and functional anatomy
Cladistic analysis of 46 cranial and dental characters supports monophyly of the Aetiocetidae, with toothed mysticetes Janjucetus and Mammalodon positioned as successive sister taxa.
Suction feeding preceded filtering in baleen whale evolution
It is shown that tooth wear in a new Late Oligocene mysticete belonging to the putatively transitional family Aetiocetidae is inconsistent with the presence of baleen, and instead indicative of suction feeding, suggesting that balean arose much closer to the origin of toothless mysticete whales than previously thought.

This work states that modern whales originated from ancient whales at or near the Eocene/Oligocene boundary, approximately 33.7 Mya, and that whale diversity peaked in the late middle Miocene and fell thereafter toward the Recent, yielding the authors' depauperate modern whale.
