ABSTRACT A new taxon of monodontid cetacean, Casatia thermophila, gen. et sp. nov., is here described on the basis of a partial skull from lower Pliocene (5.1–4.5 Ma) marginal-marine deposits of Tuscany (central Italy). This new taxon belongs to Monodontidae based on the presence of a medial exposure of the maxillae anterior and lateral to the external bony nares; it mainly differs from all other named monodontids by the presence of a median depression of the premaxillae anterior to the… 
NEW REMAINS OF CASATIA THERMOPHILA (CETACEA, MONODONTIDAE) FROM THE LOWER PLIOCENE MARINE VERTEBRATE-BEARING LOCALITY OF ARCILLE (TUSCANY, ITALY)
An incomplete cranium, three cervicals (including the axis) and two likely lumbars of a monodontid cetacean are here described from lower Pliocene (ca. 5.1–4.5 Ma) marine sandstones cropping out at
Remarkable multicuspid teeth in a new elusive skate (Chondrichthyes, Rajiformes) from the Mediterranean Pliocene
Here we report on four highly peculiar skate teeth from Arcille and Certaldo, two Pliocene localities of Tuscany (central Italy). While being attributable to Rajiformes and somewhat reminiscent of
The extinct catshark Pachyscyllium distans (Probst, 1879) (Elasmobranchii: Carcharhiniformes) in the Pliocene of the Mediterranean Sea
Sharks assigned to the carcharhiniform family Scyliorhinidae account for about 160 extant species placed in 18 genera. Most living scyliorhinids are smallto mediumsized ground sharks provided with

Early giant reveals faster evolution of large body size in ichthyosaurs than in cetaceans
TLDR
The integration of fossil and extant data can improve understanding of aquatic adaptation and gigantism as patterns of convergent evolution, particularly when interpreted in an ecological context.
On Leonardo and a fossil whale: a reappraisal with implications for the early history of palaeontology
ABSTRACT A recent reappraisal of two passages in Leonardo da Vinci’s Codex Arundel, in which the then young Leonardo reports on visiting a cave and on some sort of ʽmarine monster’, has led to the
Physiological consequences of Arctic sea ice loss on large marine carnivores: unique responses by polar bears and narwhals
TLDR
Assessment of how sea ice loss may differentially affect polar bears that hunt on the ice surface and narwhals that hunt at extreme depths below found that major ice loss translated into elevated locomotor costs that range from 3- to 4-fold greater than expected for both species.

First monodontid cetacean (Odontoceti, Delphinoidea) from the early Pliocene of the north‐western Pacific Ocean
Monodontids are among the most enigmatic cetaceans due to their scarcity in the fossil record. Previously, except for fragmentary materials, only three skulls were known from the pre‐Pleistocene;
A monodontid cetacean from the Early Pliocene of the North Sea
A partial skeleton from the Early Pliocene of Antwerp (north of Belgium), including a fragmentary skull, corresponds to the first record of a fossil member of the family Monodontidae in the North

A small elasmobranch teeth and teleost otolith asse mblage from the Piacenzian-earliest Gelasian of Tus cany (Castelnuovo Berardenga Scalo, Siena province, Italy) is described. The exc eptional
Metaxytherium subapenninum (Bruno, 1839) (Mammalia, Dugongidae), the Latest Sirenian of the Mediterranean Basin
TLDR
It is shown that M. subapenninum represents a more derived stage of evolution in comparison with the earlier Metaxytherium species, characterized in particular by an increase in body size, a increase in tusk size, and a dorsal broadening of the nasal process of the premaxilla.
A Phylogenetic Analysis of the Superfamily Platanistoidea ( Mammalia , Cetacea , Odontoceti )
  • Biology
  • 2016
TLDR
A cladistic analysis of fossil and living Platanistoidea supports theories of monophyly of the super­ family Platanismeidea and of the family platanistidae.
Morphological Evidence for the Phylogeny of Cetacea
TLDR
Many of the clades within Odontoceti in the most parsimonious trees of this study are at odds with recent phylogenetic analyses, indicating that additional analyses, which include molecular and anatomical data as well as extant and extinct taxa, are needed.
Bivalve taxonomic diversity throughout the Italian Pliocene as a tool for climatic-oceanographic and stratigraphic inferences
TLDR
Taking into account the available data on the Pliocene extinction events it has been possible to distinguish 4 different molluscan units with different climatic-oceanographic significance.
Description of an anomalous monodontid skull from west Greenland: a possible hybrid?
TLDR
The intermediate characteristics of the skull and dentition are consistent with the hypothesis that the anomalous whale was a narwhal-beluga hybrid.
