The modern giant sperm whale Physeter macrocephalus, one of the largest known predators, preys upon cephalopods at great depths. Lacking a functional upper dentition, it relies on suction for catching its prey; in contrast, several smaller Miocene sperm whales (Physeteroidea) have been interpreted as raptorial (versus suction) feeders, analogous to the modern killer whale Orcinus orca. Whereas very large physeteroid teeth have been discovered in various Miocene localities, associated diagnostic… Expand
A new longirostrine sperm whale (Cetacea, Physeteroidea) from the lower Miocene of the Pisco Basin (southern coast of Peru)
TLDR
A new genus and species of physeteroid is described and phylogenetic analysis recovers R. valenciae as one of the earliest branching stem physeteroids, interpreted as part of a mechanism leading to the loss of apical and subapical upper teeth in sperm whales during the Miocene. Expand
Macroraptorial sperm whales (Cetacea, Odontoceti, Physeteroidea) from the Miocene of Peru
TLDR
A phylogenetic analysis based on 53 characters and 21 physeteroid species confirms the monophyly of Acrophyseter and groups this genus with the larger, middle to late Miocene macroraptorial stem physeteroids Brygmophyseter and Zygophyseter. Expand
The most basal beaked whale Ninoziphius platyrostris Muizon, 1983: clues on the evolutionary history of the family Ziphiidae (Cetacea: Odontoceti)
TLDR
The morphology of the oral apparatus suggests that Ninoziphius was less specialized for suction feeding than most extant ziphiids and is the most basal stem ziphiid in the cladistic analysis. Expand
No deep diving: evidence of predation on epipelagic fish for a stem beaked whale from the Late Miocene of Peru
TLDR
A ziphiid–fish assemblage from the Late Miocene of Peru is reported, interpreted as the first direct evidence of a predator–prey relationship between a Ziphiid and epipelagic fish, and supports the hypothesis that only more derived ziphiids were regular deep divers and that the extinction of epipelagos forms may coincide with the radiation of true dolphins. Expand
Piscivory in a Miocene Cetotheriidae of Peru: first record of fossilized stomach content for an extinct baleen-bearing whale
TLDR
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.

Did the giant extinct shark Carcharocles megalodon target small prey? Bite marks on marine mammal remains from the late Miocene of Peru
TLDR
Bite marks incising fossil mammal bones collected from upper Miocene deposits of the Pisco Formation exposed at Aguada de Lomas (southern Peru) significantly expand the still scarce record of bite marks for C. megalodon and are interpreted as an apex predator whose trophic spectrum was focused on relatively small-sized prey. Expand
First Toothless Platanistoid from the Early Miocene of Patagonia: the Golden Age of Diversification of the Odontoceti
TLDR
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. Expand
Niche Partitioning in Oligocene Toothed Mysticetes (Mysticeti: Aetiocetidae)
TLDR
A new aetiocetid specimen from the upper part of Morawan Formation, Ashoro, Hokkaido, Japan, sheds new light on niche partitioning of Oligocene toothed mysticetes and evolution of body size in Mysticeti. Expand
Shark-cetacean trophic interactions during the late Pliocene in the Central Eastern Pacific (Panama)
We provide a description of the remains of a fossil whale from western Panama. The record consists of appendicular remains of a mysticete, which has been assigned to Balaenopteridae. These remains,Expand

The giant sperm whale (Physeter macrocephalus) and the dwarf (Kogia sima) and pygmy (Kogia breviceps) sperm whales represent the only three extant species of physeteroids. This group hasExpand

A new stem-sperm whale (Cetacea, Odontoceti, Physeteroidea) from the Latest Miocene of Peru
TLDR
A preliminary cladistic analysis provides a phylogenetic position of Acrophyseter nested within the stem-Physeteroidea, more basal than the clade Kogiidae + Physeteridae. Expand
Killer sperm whale: a new basal physeteroid (Mammalia, Cetacea) from the Late Miocene of Italy
TLDR
Large body size, large teeth present in both lower and upper jaw, and anteroposteriorly elongated temporal fossa and zygomatic process of the squamosal indicate that this cetacean was an active predator adapted to feeding on large prey, similarly to the extant killer whale. Expand

Sperm Whales: Social Evolution in the Ocean
TLDR
The crucial role that culture plays in the life of the sperm whale is explored, and a general model of how the ocean environment influences social behaviour and cultural evolution among mammals as well as other animals is built. Expand
Deep-diving foraging behaviour of sperm whales (Physeter macrocephalus).
TLDR
Similarity in foraging behaviour in the three regions and high diving efficiencies suggest that the success of sperm whales as mesopelagic predators is due in part to long-range echolocation of deep prey patches, efficient locomotion and a large aerobic capacity during diving. Expand

Marine mammals through time: when less is more in studying palaeodiversity

  • 2008
TLDR
Limited evidence was found for a correlation of outcrop area with marine mammal palaeodiversity, and similar patterns were identified in the cetacean and pinnipedimorph diversity data, which may point to the preservation of a genuine biological signal not overwhelmed by geological biases in the marine mammal diversity data.
