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

  title={A New Protocetid Whale (Cetacea: Archaeoceti) from the Late Middle Eocene of South Carolina},
  author={Jonathan H Geisler and Albert E. Sanders and Zhe‐Xi Luo},
Abstract A new genus and species of protocetid cetacean, Carolinacetus gingerichi, 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. That formation is also defined and named in this paper. Although the holotype skull of Carolinacetus is fragmentary, it includes the best preserved petrosal of any described specimen from the… 

Tupelocetus palmeri, a new species of protocetid whale (Mammalia, Cetacea) from the middle Eocene of South Carolina

T. palmeri is described, a new genus and species of archaeocete whale based on a single specimen from the Cross Member of the middle Eocene Tupelo Bay Formation, which has also furnished the holotype of Carolinacetus gingerichi and another member of this polytomy is Natchitochia jonesi, which is unable to differentiate these two species.

New Protocetid Whales from Alabama and Mississippi, and a New Cetacean Clade, Pelagiceti

The new specimens of Georgiacetus reported here add three additional anterior caudal vertebrae and a single more posterior caudAL vertebra to the hypodigm, which prove to be extremely helpful in determining the locomotory mode of this advanced protocetid.

A New Basal Odontocete from the Upper Rupelian of South Carolina, U.S.A., with Contributions to the Systematics of Xenorophus and Mirocetus (Mammalia, Cetacea)

Three of the characters the authors find to be odontocete synapomorphies are closely associated with soft tissue structures implicated in the production and transmission of high-frequency sounds during echolocation.

First remingtonocetid archaeocete (Mammalia, Cetacea) from the middle Eocene of Egypt with implications for biogeography and locomotion in early cetacean evolution

Recovery of a remingtonocetid in Egypt broadens the distribution of RemingtonOCetidae and shows that protocetids were not the only semiaquatic archaeocetes capable of dispersal across the southern Tethys Sea.

A new protocetid whale offers clues to biogeography and feeding ecology in early cetacean evolution

Recovery of Phiomicetus from the same bed that yielded the remingtonocetid Rayanistes afer provides the first clear evidence for the co-occurrence of the basal cetacean families RemingtonOCetidae and Protocetidae in Africa.

More-complete remains of Procolpochelys charlestonensis (Oligocene, South Carolina), an occurrence of Euclastes (upper Eocene, South Carolina), and their bearing on Cenozoic pancheloniid sea turtle distribution and phylogeny

Abstract. New and more-complete material of Procolpochelys charlestonensis Weems and Sanders, 2014 provides the first detailed information on the skull, jaw, and plastron of this species, which

Protocetid cetaceans (Mammalia) from the Eocene of India

Two new genera and species are described: Kharodacetus sahnii and Dhedacetus hyaeni, both of which are protocetid cetaceans from District Kutch in the State of Gujarat and were recovered in deposits approximately 42 million years old.

Makaracetus Bidens, a New Protocetid Archaeocete (Mammalia, Cetacea) from the Early Middle Eocene of Balochistan (Pakistan)

Makaracetus bidens is a new genus and species of late Lutetian (early middle Eocene) archaeocete collected from the Kunvit area near Rakhni, in eastern Balochistan Province, Pakistan. M. bidens was

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

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

A new middle Eocene protocetid whale (Mammalia: Cetacea: Archaeoceti) and associated biota from Georgia

A shallow-marine fossil biota was recovered from the Blue Bluff unit (formerly part of the McBean Formation) in the Upper Coastal Plain of eastern Georgia. Biochronologically significant mollusks

Remingtonocetus harudiensis, new combination, a Middle Eocene archaeocete (Mammalia, Cetacea) from Western Kutch, India

ABSTRACT A new genus of archaeocete cetaceans, Remingtonocetus, is based on revision of previously described and recently collected well preserved skull material from the Middle Eocene (Lutetian)

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 approximate 14-million-year age of the specimen makes it the oldest known member of the Balaenoptera clade by some 3 to 5 million years, and extends the fossil record of this clade closer to the divergence time estimated by some recent molecular studies.

Attockicetus praecursor, A New Remingtonocetid Cetacean from Marine Eocene Sediments of Pakistan

A new early-to-middle Eocene cetacean from the Kala Chitta Hills of northern Pakistan is described: Attockicetus praecursor new genus and species. It is based on fragmentary cranial material,

Skeletons of terrestrial cetaceans and the relationship of whales to artiodactyls

Cladistic analysis of the skeletons of two early Eocene pakicetid cetaceans, the fox-sized Ichthyolestes pinfoldi, and the wolf-sized Pakicetus attocki, indicates that cetACEans are more closely related to artiodactyls than to any mesonychian, and supports monophyly of artiodACTyls.

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

The position of Cetacea within mammalia: phylogenetic analysis of morphological data from extinct and extant taxa.

Knowledge of the phylogenetic position of the order Cetacea (whales, dolphins, and porpoises) within Mammalia is of central importance to evolutionary biologists studying the transformations of
