A 6,000+ year-old specimen of a spectacled bear from an Andean cave in Peru

  author={Marcelo Stucchi and Rodolfo Salas-Gismondi and Patrice Baby and Jean-Loup Guyot and Bruce J. Shockey},
Abstract We report the discovery of a partial skeleton of the oldest spectacled bear (Tremarctos ornatus) known to date. It was found at 2,950 m elevation in the Chaquil cave, in the Departamento de Amazonas, north central Peru. Its age, as determined by accelerated mass spectrometry conventional radiocarbon dating, was, within 50 years, 5,980 years before present (YBP). After a standard correction for Holocene irregularities of atmospheric 14C (carbon 14) levels, this conventional radiocarbon… 

Mysterious Ucumari: The Andean Bear in Nature and Culture

The only ursid native to South America, the spectacled bear (Tremarctos ornatus) still occurs in parts of the Urubamba Valley and its tributaries where human impact has been low. Small size (90–150


Peruvian citizens have led our team to their discoveries of Pleistocene cave faunas in the central Andes of Peru. These caves (Jatun Uchco, Departamento de Huanuco; Cueva Rosello, Departamento de

Andean bear Tremarctos ornatus natural history and conservation

The Andean bear is the only remaining bear species in South America and is the youngest of all ursids and the only remnant taxon within the subfamily Tremarctinae, but the limits of its current and past range are uncertain.

Ancient genomes reveal hybridisation between extinct short-faced bears and the extant spectacled bear (Tremarctos ornatus)

It is suggested that the extant spectacled bear derives substantial ancestry from Pleistocene hybridisation with an extinct short-faced bear lineage, resulting in a discordant phylogenetic signal between the mitochondrion and portions of the nuclear genome.

The genetic structure of the spectacled bear (Tremarctos ornatus; Ursidae, Carnivora) in Colombia by means of mitochondrial and microsatellite markers

The authors' analyses show evidence of high mitochondrial genetic diversity in spectacled bears, both in Colombia as well as in each of the nine regions, most particularly Norte de Santander, Nariño, and Antioquia-Córdoba.

Yucatán carnivorans shed light on the Great American Biotic Interchange

It is suggested that landscape and ecological changes caused by latest Pleistocene glaciation supported an interchange pulse that included A. wingei, P. troglodytes and Homo sapiens, and suggests a more complex history of these organisms in Middle America.

South American Fossil Carnivorans (Order Carnivora)

Carnivora is a clade of mammalian predators that evolved in northern continents during the Paleocene, and since the Miocene have invaded the southern continents (i.e., Africa and South America). They

Tremarctos ornatus (Carnivora: Ursidae)

Abstract: Tremarctos ornatus (F.G. Cuvier, 1825) is a tremarctine bear commonly known as the Andean bear. It is a medium-sized bear with black to dark red-brown pelage with dense, long, coarse fur;

Molecular Evolution (Mitochondrial and Nuclear Microsatellites Markers) in the Andean Bear (Tremarctos ornatus; Ursidae, Carnivora): How Many ESUs Are There?

We sequenced mitochondrial genes ND5, 12s rRNA, and COI in 302 Andean or spectacled bears (Ursidae) from Venezuela, Colombia, Ecuador, Peru, and Bolivia. Of this total, 294 of the bears were from the

From aardwolves and bandicoots to yapoks and zorillas, Ernest P. Walker's Mammals of the World is the most comprehensive-the pre-eminent-reference work on mammals. Now, completely revised and

Ecology, Distribution, and Food Habits of Spectacled Bears, Tremarctos ornatus, in Peru

A study of the behavior and ecology of the spectacled bear, Tremarctos ornatus , in Peru revealed that they occur in all three ranges of the Peruvian Andes, with the majority in the “ceja de selva,”

Are There Andean Bears in Panamá

Abstract We present the results of a 2007 survey for Andean bears (Tremarctos ornatus) at Serranía de Pirre, Panamá. We surveyed game trails using methodology developed by the Andean Bear Program of

Molecular population genetic analysis of the spectacled bear (Tremarctos ornatus) in the northern Andean area.

The low heterozygosity and the population fragmentation could be explained by ancient events related to the bear colonization, with the arrival of humans beings in the Americas, and/or with the glacial maximum, 16.000-30.000 years ago.

A Simplified Approach to Calibrating 14C Dates

We propose a simplified approach to the calibration of radiocarbon dates. We use splines through the tree-ring data as calibration curves, thereby eliminating a large part of the statistical scatter
