Zygophyseter varolai, a new genus and species of Physeteroidea (Cetacea, Odontoceti), is based on an almost complete skeleton from the Late Miocene (Tortonian) in southern Italy. The extreme elongation of the zygomatic process of the squamosal and the circular supracranial basin (probably for housing the spermaceti organ) delimited by a peculiar anterior projection of the supraorbital process of the right maxilla are the most distinctive features of this bizarre sperm whale. Large body size… 
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.
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.
Systematic revision of a Miocene sperm whale from Patagonia, Argentina, and the phylogenetic signal of tympano-periotic bones in Physeteroidea
TLDR
It is suggested that sperm whale tympanoperiotics retain many plesiomorphic characters and are diagnostic only between kogiids and non-kogiid physeteroids, and not at the species level.
Koristocetus pescei gen. et sp. nov., a diminutive sperm whale (Cetacea: Odontoceti: Kogiidae) from the late Miocene of Peru
TLDR
Koristocetus evokes a long history of high diversity, morphological disparity, and sympatric habits in fossil kogiids, thus suggesting that the comprehension of the evolutionary history of pygmy and dwarf sperm whales is still far from being exhaustive.
The giant bite of a new raptorial sperm whale from the Miocene epoch of Peru
TLDR
It is proposed that Leviathan fed mostly on high-energy content medium-size baleen whales, together with the contemporaneous giant shark Carcharocles megalodon, which had a profound impact on the structuring of Miocene marine communities.
New sperm whale remains from the late Miocene of the North Sea and a revised family attribution for the small crown physeteroid Thalassocetus Abel, 1905
In spite of a continuously expanding physeteroid fossil record, our understanding of the origin and early radiation of the two modern sperm whale families Kogiidae Gill, 1871 (including the pygmy and
A new kogiid sperm whale from northern Italy supports psychrospheric conditions in the early Pliocene Mediterranean Sea
Among living cetaceans, dwarf and pygmy sperm whales (Kogia) are the only members of the family Kogiidae, regarded as diminutive and elusive relatives of the great sperm whale Physeter. Kogiids are
A new physeteroid from the late Miocene of Peru expands the diversity of extinct dwarf and pygmy sperm whales (Cetacea: Odontoceti: Kogiidae)
TLDR
Two skulls of Kogiidae from the Messinian (upper Miocene) portion of the Pisco Formation of Peru are reported on, representing several cranial specimens from Mio-Pliocene localities of the Northern Hemisphere.
Albicetus oxymycterus, a New Generic Name and Redescription of a Basal Physeteroid (Mammalia, Cetacea) from the Miocene of California, and the Evolution of Body Size in Sperm Whales
TLDR
A phylogenetic analysis of Albicetus oxymycterus with other fossil and living Physeteroidea resolves its position as a stem physeteroid, implying that large body size and robust dentition in physeteroids evolved multiple times and in distantly related lineages.

TLDR
A new skull belonging to the species Eurhinodelphis cocheteuxi, found in the upper Lower–Middle Miocene of Antwerp, is the basis of a redescription and systematic revision of the species and the main results of the cladistic analyses are a sister‐group relationship between E. cocheteuxo and the extant family Ziphiidae, and a more basal position of the superfamily Physeteroidea in the tree.
Revised phylogeny of the Physeteridae (Mammalia: Cetacea) in the light of Placoziphius Van Beneden, 1869 and Aulophyseter Kellogg, 1927
TLDR
A recently found Middle Miocene sperm whale skeleton from Stotzing (Burgenland, Austria) represents Placoziphius duboisii VAN BENEDEN, 1869, described from the MiddleMiocene Crag d'Anvers (Antwerp, Belgium), which is regarded as apomorphic characters of the species.
A new genus of kentriodontid (Cetacea: Odontoceti) from the Miocene of south Italy
TLDR
Rudicetus squalodontoides confirms the presence of kentriodontids from Italy and the Mediterranean Basin, as all previous reports were based on fragmentary specimens.
KOGIA PUSILLA FROM THE MIDDLE PLIOCENE OF TUSCANY (ITALY) AND A PHYLOGENETIC ANALYSIS OF THE FAMILY KOGIIDAE (ODONTOCETI, CETACEA)
TLDR
Phylogenetically, an old separation (at least in the Lower Miocene) of Kogiidae and Physeteridae is suggested and supposed apomorphies in the morphology and the extension of the supracranial basin that houses the large air sacs and the spermaceti organ are considered.
Retroposon analysis of major cetacean lineages: The monophyly of toothed whales and the paraphyly of river dolphins
TLDR
The combination of SINE and flanking sequence analysis suggests a topology and set of divergence times for odontocete relationships, offering alternative explanations for several long-standing problems in cetacean evolution.
Phylogeny of all major groups of cetaceans based on DNA sequences from three mitochondrial genes.
TLDR
A molecular phylogeny based on 1,352 base pairs of two mitochondrial ribosomal gene segments and the mitochondrial cytochrome b gene for all major groups of cetaceans contradicts this long-accepted taxonomic subdivision and suggests a more recent origin of baleen whales than has been previously assumed.
Petrosal (periotic) and inner ear of a Pliocene kogiine whale (Kogiinae, Odontoceti): implications on relationships and hearing evolution of toothed whales
TLDR
Petrosal apomorphies suggest that physeterids and ziphiids are sister groups among the odontocetes, and that the Mysticeti and OdontOCeti are both monophyletic.
SPERM WHALE PHYLOGENY REVISITED: ANALYSIS OF THE MORPHOLOGICAL EVIDENCE
TLDR
The results of this analysis unambiguously support a monophyletic Odontoceti including the sperm whales, and the fossil evidence refutes a sperm whale/baleen whale clade.
