A right metacarpal III represents the first North American record of the giant anteater (Myrmecophaga tridactyla). Recovered in northwestern Sonora, Mexico, with a rich vertebrate fauna of early Pleistocene (Irvingtonian) age, it belongs to a cohort of large mammals that dispersed from South America to North America along a savanna corridor. Presumably habitat and climatic changes have subsequently driven this mammalian family more than 3000 kilometers back into Central America from its former…

Myrmecophaga tridactyla (Pilosa: Myrmecophagidae)
Abstract: The monospecific giant anteater, Myrmecophaga tridactyla Linnaeus, 1758, is the largest of the 4 species of New World vermilinguans. A feeding specialist on ants and termites, it occupies…
The Great American Biotic (Faunal) Interchange
This is the story of the revolutionary changes to South American mammals that occurred when it became possible for mammals from North America to pass to South America. This probably began as early as…
First fossil skull of an anteater (Vermilingua, Myrmecophagidae) from northern South America, a taxonomic reassessment of Neotamandua and a discussion of the myrmecophagid diversification
TLDR
A synthetic model on the diversification of these xenartrans during the late Cenozoic based on the probable relationship between their intrinsic ecological constraints and some major abiotic changes in the Americas is proposed.
The paleoecology of extinct xenarthrans and the Great American Biotic Interchange
The Xenarthra were the most successful South American mammals to participate in the Great American Biotic Interchange (GABI) and representatives of each family dispersed to at least the middle…

A New Genus of Megalonychid Ground Sloth (Mammalia, Xenarthra) from the Late Pleistocene of Quintana Roo, Mexico
TLDR
A new genus and species of late Pleistocene megalonychid sloth, Nohochichak xibalbahkah, is described from Hoyo Negro, a chamber in the Sac Actun cave system, Quintana Roo, Mexico, which indicates that the number of sloth taxa involved in the Great American Biotic Interchange is greater than previously understood.
The Charismatic Giant Anteater (Myrmecophaga tridactyla): A Famous John Doe?
TLDR
This study evaluates the current level of scientific knowledge of the giant anteater (Myrmecophaga tridactyla) and recovered 81 articles related to the species, scattered throughout 47 journals.
Increased xenarthran diversity of the Great American Biotic Interchange: a new genus and species of ground sloth (Mammalia, Xenarthra, Megalonychidae) from the Hemphillian (late Miocene) of Jalisco, Mexico
TLDR
Comparison and analysis of the type specimen, a mandible, shows a closer relationship to South American taxa than those from North America or the Caribbean, which suggests that during the early stages of the Great American Biotic Interchange there were two separate dispersal events of megalonychid sloths.
Eremotherium Laurillardi (Lund) (Xenarthra, Megatheriidae), the Panamerican giant ground sloth: Taxonomic aspects of the ontogeny of skull and dentition
TLDR
It is demonstrated that the ‘dwarf’ species is based on the remains of immature individuals, at very early ontogenetic stages, of the large‐sized Eremotherium species, and it is reaffirmed that the most parsimonious hypothesis is to consider all large-sized E Remotherium remains as belonging to a single species of Panamerican distribution.
FIRST RECORD OF FOSSIL CHELYDRID AND TRIONYCHID TURTLES (TESTUDINES) FROM THE PLEISTOCENE OF SONORA, MEXICO
The late Pleistocene of northern Mexico is relatively poorly understood, and represented by only a few fossil localities. One such locality is Térapa, located in east-central Sonora. The deposit…

A HISTORY OF SAVANNA VERTEBRATES IN THE NEW WORLD. Part II: South America and the Great Interchange
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.
Mammalian faunal dynamics of the Great American Interchange
TLDR
The MacArthur-Wilson faunal equilibrium hypothesis correctly predicts a marked increase in originations, number of genera, and turnover rate for the South American fauna during the peak of the interchange and the continued increase in South American land mammal genera after the interchange had largely ceased.
Calibration of the Great American Interchange
TLDR
Radioisotopic age determinations of tuffs and magnetostratigraphy of Late Tertiary mammal-bearing beds in Catamarca Province, northwest Argentina are obtained for the durations and boundaries of beds of Chasicoan through Chapadmalalan (Pliocene) age.
