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…

STATUS OF STUDIES ON FOSSIL MARINE MAMMALS

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

TLDR
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.

FOSSIL SIRENIA OF THE WEST ATLANTIC AND CARIBBEAN REGION. VII. PLEISTOCENE TRICHECHUS MANATUS LINNAEUS, 1758

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)

TLDR
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

TLDR
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.

TLDR

TLDR
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.

TLDR
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.
