Abstract The stable carbon and oxygen isotopic ratios present in dentine and tooth enamel from one Mixotoxodon larensis specimen from Hihuitlán, Michoacán, México, were analyzed. Similar to otherExpand
A New Species of Xotodon (Notoungulata, Toxodontidae) from Northwestern Argentina
This represents the first record of a toxodontid in the Neogene lowlands of northwestern Argentina and contributes to the authors' knowledge of this family in the region. Expand
New toxodontid (Notoungulata) from the Early Miocene of Mendoza, Argentina
Abstract We describe a new toxodontid species, Nesodon taweretus sp. nov., from the Aisol Formation in Mendoza Province, central-west Argentina. Nesodon is a frequently found Toxodontidae, member ofExpand
First record of Toxodontidae (Mammalia, Notoungulata) from the late Miocene—early Pliocene of the southern central Andes, NW Argentina
Abstract. A new species of toxodontid notoungulate, Xotodon maimarensis n. sp., is described from the Maimará Formation (late Miocene—early Pliocene), Jujuy Province, northwestern Argentina. ThisExpand
The Native Ungulates of South America (Condylarthra and Meridiungulata)
The ancient, native ungulates were another fascinating group, which sadly has become totally extinct, but that we now understand were related to the northern Perissodactyla or odd-toed ungulates.Expand
Late Pleistocene toxodont remains of Tamaulipas, Mexico. Confirmation of the occurrence of Mixotoxodon larensis (Van Frank, 1957) and an analysis of sexual dimorphism
Abstract The Mexican record of notoungulates is scarce. So far, the only described species in Mexico is represented by Mixotoxodon larensis, which has limited in Michoacan and Veracruz. This workExpand
Guatemala's Late Pleistocene (Rancholabrean) fauna: Revision and interpretation
Abstract We present a revision, dating and interpretation of the Late Pleistocene megafauna of Guatemala based on paleontological material located in collections in the country and other fossilsExpand
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
Revisiting Paleoindian exploitation of extinct North American mammals
In 2002, we assessed all sites known to us that had been suggested to provide evidence for the association of Clovis-era archaeological material with the remains of extinct Pleistocene mammals inExpand
The First Tertiary Fossils of Mammals, Turtles, and Fish from Canada's Yukon
ABSTRACT Despite over a century of prospecting and field research, fossil vertebrates are exceedingly rare in Paleogene and Neogene rocks in northern Canada's Yukon Territory. Here, we describe theExpand


A perspective on mammal biodiversity and zoogeography in the Late Pleistocene of México
The current distribution of several groups of mammal species can be explained in part as an effect of Pleistocene glaciations, but the particular dynamic mechanism remains largely unknown due to lack of detailed data. Expand
New Pleistocene vertebrate fauna from El Salvador
The discovery of an Early-Middle Pleistocene continental vertebrate fauna from El Salvador is here reported. These fossils provide information about a poorly studied geographic area that played anExpand

The Pleistocene mammals of Costa Rica
ABSTRACT Fossil mammals are known from 41 localities of Pleistocene age in Costa Rica. Most of these mammals are proboscideans referable to the gomphothere Cuvieronius hyodon. One occurrence ofExpand
Diet and habitat of toxodont megaherbivores (Mammalia, Notoungulata) from the late Quaternary of South and Central America
Abstract The toxodont megaherbivores Toxodon and Mixotoxodon were endemic to South and Central America during the late Quaternary. Isotopic signatures of 47 toxodont teeth were analyzed toExpand
Late Cenozoic vertebrates from Honduras and El Salvador
ABSTRACT The subhumid Pacific slopes of El Salvador and Honduras contain a valuable record of late Cenozoic terrestrial vertebrates. Vast ignimbrite flows, mainly of mid-Miocene age, and subsequentExpand
A 16,000 year pollen record of vegetational change in central Texas
Abstract Fossil pollen records from peat bogs are used to propose a 16,000‐year paleoenvironmental sequence for central Texas. Evidence suggests that during the late Fullglacial, central Texas wasExpand
Paleoenvironmental records spanning more than 30,000 years are used to reconstruct an overview of vegetational changes occurring in Texas during the late-Quaternary. Primary emphasis is devoted toExpand
A late Holocene pollen sequence from Aronow Bog, northern Harris County, Texas
The analysis of fossil pollen, spores and charcoal from 1.15 m of sediments deposited over a period of more than 1,000 years at Aronow Bog in northern Harris County, Texas is the first detailedExpand
