Abstract A new basal basilosaurid cetacean, Basilotritus uheni n. gen. n. sp., comes from the late middle Eocene (Bartonian) of Ukraine. It is the earliest dated record of a cetacean from Eastern Europe. The tympanic bulla of Basilotritus uheni shares basilosaurid synapomorphies but possesses unusual traits inherited from protocetids. Cetaceans related to Basilotritus uheni and referred to as Eocetus or “Eocetus” have been recorded from Africa, Europe, North America and South America. “Eocetus… 

A basilosaurid archaeocete (Cetacea, Pelagiceti) from the Late Eocene of Oregon, USA

These vertebrae represent the first confirmed specimen of a Late Eocene basilosaurid from the North Pacific, and are reviewed here in the context of LateEocene paleoceanography and cetacean evolution.

Skull and partial skeleton of a new pachycetine genus (Cetacea, Basilosauridae) from the Aridal Formation, Bartonian middle Eocene, of southwestern Morocco

It is inferred from their pachyosteosclerotic vertebrae that pachycetines were probably sirenian-like slow swimmers living in shallow coastal seas and feeding on passing fish and mobile invertebrates.

Eocene Basilosaurid Whales from the La Meseta Formation, Marambio (Seymour) Island, Antarctica

Abstract. Basal fully aquatic whales, the basilosaurids are worldwide known from Bartonian—Priabonian localities, indicating that this group was widely distributed during the late middle Eocene. In

A small whale reveals diversity of the Eocene cetacean fauna of Antarctica

Abstract Cetacean fossils have been recorded from middle and late Eocene deposits on Seymour Island since the beginning of the twentieth century and include fully aquatic Basilosauridae and stem

The anatomy and phylogenetic affinities of Cynthiacetus peruvianus, a large Dorudon-like basilosaurid (Cetacea, Mammalia) from the late Eocene of Peru

In contrast with previous hypotheses, in which Saghacetus was the sister taxon of the Pelagiceti, the results of the analysis reveal this taxon as the most basal basilosaurid.

A Giant Eocene Whale from Ukraine Uncovers Early Cetacean Adaptations to the Fully Aquatic Life

The earliest fully aquatic cetaceans arose during the Middle Eocene; however, the earliest stage of their divergence is obscure. Here, we provide a detailed redescription of an unusual early

Protocetid (Cetacea, Artiodactyla) bullae and petrosals from the middle Eocene locality of Kpogamé, Togo: new insights into the early history of cetacean hearing

Extant cetaceans are fully aquatic mammals with deep modifications of their sensory organs, notably of the sound perception pathway. Early diverging cetaceans, known as archaeocetes, show a diversity



Basilosaurus drazindai and Basiloterus hussaini, New Archaeoceti (Mammalia, Cetacea) from the Middle Eocene Drazinda Formation, with a Revised Interpretation of Ages of Whale-Bearing Strata in the Kirthar Group of the Sulaiman Range, Punjab (Pakistan)

Two new basilosaurid archaeocetes are described from middle Eocene (Bartonian) green shales in the middle part of the Drazinda Formation in the Sulaiman Range of southwestern Punjab. Basilosaurus

A New Protocetid Whale (Cetacea: Archaeoceti) from the Late Middle Eocene of South Carolina

A new genus and species of protocetid cetacean is described from a partial skull, the posterior portion of both dentaries, 13 vertebrae, and elements of 15 ribs found in the Cross Member of the late middle Eocene Tupelo Bay Formation in Berkeley County, South Carolina.

New species of protocetid archaeocete whale, Eocetus wardii (Mammalia: Cetacea) from the middle Eocene of North Carolina

A new species of protocetid archaeocete, Eocetus wardii n. sp., is named based on material from the late Lutetian (middle Eocene, 43-44 Ma) Comfort Member of the Castle Hayne Formation, North

The emergence of whales : evolutionary patterns in the origin of Cetacea

Synopsis of the Earliest Cetaceans: Pakicetidae, Ambulocet Families, Remingtonocet families, and Protocetidae; and implications of Vertebral Morphology for Locomoter Evolution in Early Cetacea.

Postcranial Osteology of the North American Middle Eocene Protocetid Georgiacetus

The purpose of this report is to describe the postcranial remains of G. vogtlensis and compare them with those of other archaeocetes.


The pelves resemble those of Basilosaurus, documenting a similar stage of hind limb reduction in dorudontines and suggesting that Chrysocetus was not able to support its body on land.

Aegyptocetus tarfa, n. gen. et sp. (Mammalia, Cetacea), from the Middle Eocene of Egypt: Clinorhynchy, Olfaction, and Hearing in a Protocetid Whale

The pattern of tooth marks preserved on the ribs of Aegyptocetus indicates that the individual studied here was attacked by a large shark, but it is not certain whether this was the cause of death.

An archaeocete whale (Cetacea: Archaeoceti) from the Eocene Waihao Greensand, New Zealand

ABSTRACT An incomplete skull, four vertebrae, two teeth, and other, smaller fragments confirm the early occurrence of dorudontine whales (Cetacea: Archaeoceti: Basilosauridae) in the Southwest

Form, Function, and Anatomy of Dorudon Atrox (Mammalia, Cetacea): An Archaeocete from the Middle to Late Eocene of Egypt

Reconstructions of the soft anatomy of Dorudon atrox, along with analyses of functional morphology show that D. atrox was a caudally propelled swimmer, much like modem cetaceans.
