The following historical scenario is proposed to explain the available data on manatee evolution. Protosiren-like sirenians probably reached the isolated South American continent in the Eocene; this dispersal and subsequent genetic isolation marked the origin of the Trichechidae. The earliest known probable trichechid, Potamosiren from Colombia, is Middle Miocene (Friasian) in age, and lacks the horizontally-replaced supernumerary molars which characterize later manatees. Up to the Late Miocene…

A 30-year renaissance in research on fossil marine mammals has brought advances on several fronts and suggests potential directions for future study. Gingerich and Russell have described Pakicetus,

Diets, habitat preferences, and niche differentiation of Cenozoic sirenians from Florida: evidence from stable isotopes

This study of Cenozoic sirenians from Florida further demonstrates that stable isotopes can test hypotheses previously based on morphology and associated floral and faunal remains and result in a more insightful approach to reconstructing the paleobiology of this interesting group of ancient aquatic mammalian herbivores.


Abstract All known Pleistocene fossils of manatees from North America are conspecific with the living West Indian manatee, Trichechus manatus. However, those of late Pleistocene (late Rancholabrean)

The semiaquatic niche of Libycosaurus, combined with the distribution and relationships of its late Miocene species, indicates that by the end of the Miocene, wet environments connected the Lake Chad Basin to the Libyan Sirt Basin, across what is now the Sahara desert.

The evolutionary history of manatees told by their mitogenomes

The results provide novel insight into the evolutionary history of the Trichechidae during the Late Miocene, which was influenced by geological events, such as Amazon Basin formation.



A model for paleobiogeography of South American cricetine rodents

A model for the paleobiogeographic history of South American cricetine rodents is proposed based on new and/or recently published fossil, geological, paleobotanical and radioisotope data. Cricetine

Review of Early Sirenia

Advances in the authors' knowledge of fossil sirenians over the past four decades are reviewed and a cladistic phylogeny of the order presented and Salient features of the recently re-prepared type skull of the most primitive known sirenian, Prorastomus (middle Eocene, Jamaica), are summarised.

Pleistocene changes in the flora of the high tropical Andes

Geological data show that high Andean habitats have been available for plant colonization only since the end of the Tertiary. The manner in which plant species moved into these habitats, the times

A HISTORY OF SAVANNA VERTEBRATES IN THE NEW WORLD. Part II: South America and the Great Interchange

The history of South American savanna vertebrates is outlined and the dramatic climax of Nature's experiment when the two American faunas were thrown together by way of the isthmian connection is reviewed.

The modern Sirenia: their distribution and status

The two authors have, over 12 years, endeavoured by means of personal visits to the Guianas, Australia, Torres Strait, Ceylon and elsewhere, to gather material so as to summarize the present distribution and status of the Sirenia.

The Status of the Manatee in the Everglades National Park, with Notes on Its Natural History

Observations were begun in May, 1949, and continued through April, 1950, and it seems fitting that this early opportunity be taken to report on the apparent status of the manatee in this park, and to record such information on its natural history as is at hand.
