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 other

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.

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 of

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. This

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.

A New Toxodontidae (Mammalia, Notoungulata) from the Upper Pliocene–Lower Pleistocene of Uruguay

ABSTRACT A specimen of Toxodontidae from the upper Pliocene–lower Pleistocene of Uruguay is studied in this paper. The material consists of associated skull and mandibular fragments previously

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

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 of

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 subsequent

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 was


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 to

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 detailed

Análisis topológico y sistemático del Toxodonte de Bajo de los Barrantes, provincia de Alajuela, Costa Rica
