Abstract. Diet and habitat were estimated, based on stable isotopes, for six species of proboscideans inhabiting the Americas during the Pleistocene. In North America, Mammuthus columbi (Elephantidae) was a mixed C3/C4 herbivore inhabiting open areas, while Mammut americanum (Mammutidae) fed exclusively on C3 plants and preferred closed areas. In contrast, members of the family Gomphotheriidae showed a wide range of food preference and habitats. This is the case of Cuvieronius tropicus, a… Expand

Extinction of North American Cuvieronius (Mammalia: Proboscidea: Gomphotheriidae) driven by dietary resource competition with sympatric mammoths and mastodons
Abstract. The gomphotheres were a diverse and widespread group of proboscideans occupying Eurasia, North America, and South America throughout the Neogene. Their decline was temporally and spatially… Expand
Feeding ecology of the gomphotheres (Proboscidea, Gomphotheriidae) of America
TLDR
It is suggested that American gomphotheres displayed generalist feeding habits, allowing them to inhabit different environments in extensive areas of the continents, and survive to the end of the Pleistocene. Expand
Dietary ecology of Pleistocene mammoths and mastodons as inferred from dental microwear textures
TLDR
The results demonstrate that the mammoths and mastodons here examined ate foods with similar textural properties, despite consuming plants with disparate stable isotope values, and suggest that extinct proboscideans are generalist feeders similar to extant elephants. Expand
Dietary resource partitioning among three coeval proboscidean taxa (Anancus capensis, Mammuthus subplanifrons, Loxodonta cookei) from the South African Early Pliocene locality of Langebaanweg E Quarry
Abstract The co-existence of megaherbivores in present-day ecosystems is uncommon. During the Early Pliocene, three large proboscidean taxa (Anancus capensis, Mammuthus subplanifrons and Loxodonta… Expand

Feeding habits and habitat of herbivorous mammals from the Early–Late Hemphillian (Miocene) of Costa Rica
TLDR
Carbon and oxygen stable isotope values in the dental enamel of fossils were used to infer the diet and habitat of the extinct equids Calippus hondurensis, Dinohippus mexicanus, and ProtohippUS gidleyi and the llama Hemiauchenia vera of the Early–Late Hemphillian from San Gerardo de Limoncito, Puntarenas province, Costa Rica.

Multiproxy evidence for leaf-browsing and closed habitats in extinct proboscideans (Mammalia, Proboscidea) from Central Chile
TLDR
A range of multiproxy approaches and new radiocarbon datings were used to study the autoecology of Chilean gomphotheres, the only group of proboscideans to reach South America during the Great American Biotic Interchange. Expand
Late Pleistocene Mammuthus and Cuvieronius (proboscidea) from Térapa, Sonora, Mexico
Abstract What is currently known about Mexico paleontology and specifically the proboscideans has centered in the central and southern states, with much of the north largely unknown. Here we report… Expand

An examination of dietary diversity patterns in Pleistocene proboscideans (Mammuthus, Palaeoloxodon, and Mammut) from Europe and North America as revealed by dental microwear
TLDR
Dental microwear analysis was used to study the dietary traits of fossil proboscideans in eleven samples from nine Pleistocene localities from Europe and North America, finding different dietary trends in the latter two genera might be the result of a trend towards niche differentiation in these taxa.

Geographic variation of diet and habitat of the Mexican populations of Columbian Mammoth (Mammuthus columbi)

Mammoths and mylodonts: Exotic species from two different continents in North American Pleistocene faunas
TLDR
Despite their association in North American faunas, mammoths did not disperse into South America and mylodont sloths were unable to disperse into Eurasia, suggesting there were some aspects of their ecology they did not have in common and there existed a limited zone of conditions that permitted them to share common habitat.
