Abstract. The inner ear of the two higher clades of modern cetaceans (Neoceti) is highly adapted for hearing infrasonic (mysticetes) or ultrasonic (odontocetes) frequencies. Within odontocetes, Platanistoidea comprises a single extant riverine representative, Platanista gangetica, and a diversity of mainly extinct marine species from the late Oligocene onward. Recent studies drawing on features including the disparate tympanoperiotic have not yet provided a consensus phylogenetic hypothesis for… 

First records of extinct kentriodontid and squalodelphinid dolphins from the Upper Marine Molasse (Burdigalian age) of Switzerland and a reappraisal of the Swiss cetacean fauna

The Swiss Upper Marine Molasse (OMM) documents a transgression event dated to around 21 to 17 million years in which dolphin and other vertebrate remains have been reported. We revised the whole

Evolution of whale sensory ecology: Frontiers in nondestructive anatomical investigations

Advances in knowledge of sensory system anatomy as informed by the use of nondestructive imaging techniques are reviewed, with a focus on applied methods in computed tomography (CT and μCT), and key questions that remain to be addressed are identified.



Evidence for convergent evolution of ultrasonic hearing in toothed whales (Cetacea: Odontoceti)

This discovery implies that either the lineage leading to this Olympicetus-like taxon lost the ability to hear ultrasonic sound, or adaptations for ultrasonic hearing evolved twice, once in xenorophids and again on the stem of the odontocete crown group.

Morphological variation among the inner ears of extinct and extant baleen whales (Cetacea: Mysticeti)

Traditional comparative anatomy and landmark‐based 3D‐geometric morphometric analyses were performed to investigate the anatomical diversity of the inner ears of extinct and extant mysticetes in comparison with other cetaceans, and results indicate variation among mysticete species.

First Toothless Platanistoid from the Early Miocene of Patagonia: the Golden Age of Diversification of the Odontoceti

A partitioning of the ecological niches in the early phases of platanistoid evolution, as well as a high diversification of feeding methods previously underestimated for this period, suggests ecological adaptations have a strong evolutionary pressure in odontocete communities and should be further explored.

Petrosal (periotic) and inner ear of a Pliocene kogiine whale (Kogiinae, Odontoceti): implications on relationships and hearing evolution of toothed whales

Petrosal apomorphies suggest that physeterids and ziphiids are sister groups among the odontocetes, and that the Mysticeti and OdontOCeti are both monophyletic.

Anatomical evidence for low frequency sensitivity in an archaeocete whale: comparison of the inner ear of Zygorhiza kochii with that of crown Mysticeti

Morphological features of the vestibular system indicates that Zygorhiza was more sensitive to head rotations than extant mysticetes are, which likely indicates higher agility in the ancestral taxon.

A new fossil dolphin Dilophodelphis fordycei provides insight into the evolution of supraorbital crests in Platanistoidea (Mammalia, Cetacea)

Facial crests among fossil and living Platanistoidea were examined and it was determined that the onset of crest elaboration or enlargement and the evolution of crest pneumatization among the platanistoids were separate events, with crest enlargement beginning in the Oligocene.

Arktocara yakataga, a new fossil odontocete (Mammalia, Cetacea) from the Oligocene of Alaska and the antiquity of Platanistoidea

With a geochronologic age between ∼29–24 million years old, Arktocara is among the oldest crown Odontoceti, reinforcing the long-standing view that the diversification for crown lineages must have occurred no later than the early Oligocene.

Petrosal and Inner Ear of a Squalodontoid Whale: Implications for Evolution of Hearing in Odontocetes

Several inner ear structures specialized for high frequency hearing are identified in a fossil squalodontoid whale from the Chandler Bridge Formation of South Carolina using serial grinding and computerized reconstruction.

Low-frequency hearing preceded the evolution of giant body size and filter feeding in baleen whales

The first anatomical analyses and frequency range estimation of the inner ear in Oligocene fossils of archaic toothed mysticetes from Australia and the USA are reported, suggesting that the low-frequency hearing of baleen whales has remained relatively unchanged over the last approximately 34 Myr, being present before the evolution of other signature mysticete traits.
