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 spatiallyExpand
Feeding ecology of the gomphotheres (Proboscidea, Gomphotheriidae) of America
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
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 LoxodontaExpand
Isotopic evidence for mammalian diets and environment in Early Pliocene Yepómera, Mexico
Abstract Concurrent expansion of grassland habitat in the Americas and first appearances of immigrant taxa to Mexico via the Great American Biotic Interchange (GABI) during the Late Miocene to EarlyExpand
Feeding habits and habitat of herbivorous mammals from the Early–Late Hemphillian (Miocene) of Costa Rica
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
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 reportExpand
Late Pleistocene ecological, environmental and climatic reconstruction based on megafauna stable isotopes from northwestern Chilean Patagonia
Abstract Stable isotope analyses have been performed on the bioapatite (δ 13 C; δ 18 O) and collagen (δ 13 C; δ 15 N) of four late Pleistocene South American megafaunal taxa ( Notiomastodon platensisExpand
The life story of a gomphothere from east-central Mexico: A multidisciplinary approach
Abstract The Gomphotheriidae family belongs to the Proboscidea order. Gomphotheres were elephant-like mammals whose representatives inhabited North America from the Middle Miocene to the lateExpand


An examination of dietary diversity patterns in Pleistocene proboscideans (Mammuthus, Palaeoloxodon, and Mammut) from Europe and North America as revealed by dental microwear
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. Expand
Geographic variation of diet and habitat of the Mexican populations of Columbian Mammoth (Mammuthus columbi)
Abstract Isotopic data (δ13C and δ18O) for 25 enamel samples from Mammuthus columbi for 13 Mexican localities are provided. On average, the samples provide evidence of a mixed C3/C4 diet. TheExpand
Mammoths and mylodonts: Exotic species from two different continents in North American Pleistocene faunas
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.

The Pleistocene Gomphotheriidae (Proboscidea) from South America
Abstract Gomphotheres arrived in South America during the “Great American Biotic Interchange” and occurred in South America from the early middle Pleistocene (Ensenadan Land-mammal Age) to the lateExpand
A paleoecological paradox: the habitat and dietary preferences of the extinct tethythere Desmostylus, inferred from stable isotope analysis
Abstract The Desmostylia, an extinct order of mammals related to sirenians and proboscideans, are known from the late Oligocene to late Miocene of the North Pacific. Though often categorized asExpand
Mastodon herbivory in mid-latitude late-Pleistocene boreal forests of eastern North America
Abstract Skeletal remains of the extinct American mastodon have often been found with deposits of short, decorticated twigs intermixed with plant fragments presumed to be gastrointestinal or fecalExpand
The isotopic ecology of late Pleistocene mammals in North America: Part 1. Florida
Mammoths and mastodons are common in Pleistocene deposits, yet these proboscideans and many other animals disappeared suddenly ≈10,000 years ago. In this study, we reconstruct the diets ofExpand
Mammalian herbivore communities, ancient feeding ecology, and carbon isotopes: A 10 million-year sequence from the Neogene of Florida
ABSTRACT Medium- to large-bodied mammalian herbivores are taxonomically diverse and comprise a large component of the highly fossiliferous Neogene terrestrial sedimentary sequence from Florida. InExpand
Mastodons and mammoths in the Great Lakes region, USA and Canada: new insights into their diets as they neared extinction.
