“…Also, these exogenous particles are more abundant in open areas (Janis and Fortelius, 1988; Fortelius and Solounias, 2000), such as the ones previously inferred for the fossil localities of the northern samples (Gutiérrez Bedolla et al, 2016; Marín-Leyva et al, 2016b), which supports the ingestion of grasses. Given that the studied sites have similar elevations—La Cinta-Portalitos ranges from 1750−2350 masl (meters above sea level), La Piedad-Santa Ana ranges from 1700−2500 masl, and Viko Vijin ranges from 1800−2400 masl (Jiménez-Hidalgo et al, 2011; Díaz-Sibaja, 2013)—altitude seems not to be related to the observed dietary trends.…”

“…The bison samples of this fauna come from localities Oax-3 La Pedrera and Oax-7 Río Tejupam. The inferred paleoenvironment for Oax-3 is a floodplain (Jiménez-Hidalgo et al, 2011) with the presence of short-lived vegetation in a wetland setting (Guerrero-Arenas et al, 2013). Locality Oax-7 was fluvial, possibly a meandering system in an open setting (Jiménez-Hidalgo et al, 2011).…”

Bison antiquus Leidy, 1852 was one of the largest and most widely distributed megafaunal species during the Late Pleistocene in North America, giving rise to the modern plains bison in the middle Holocene. Despite the importance of the ancient bison, little is known about its feeding ecology. We employed a combination of extended mesowear, and mesowear III to infer the dietary preference and habitat use of three Mexican samples of B. antiquus. These included two northern samples—La Piedad-Santa Ana and La Cinta-Portalitos—from the Transmexican Volcanic Belt morphotectonic Province, as well as one southern sample—Viko Vijin—from the Sierra Madre del Sur morphotectonic province. We found that the northern Mexican samples were primarily nonstrict grazers, whereas the southern sample displays a pattern consistent with mixed feeding habits. This suggests variability among the diets of the bison from these samples, caused by different paleoenvironments. This evidence complements the paleoenvironmental reconstructions in the studied localities; for the northern samples, open prairies composed of patches of woodland or shrubland and, for the southern locality, a fluvial floodplain with short-lived vegetation. In both scenarios, grasses (Poaceae) were nondominant. The dietary habits of our samples of ancient bison in Mexico are the southernmost dietary inference for the species in North America and expand our knowledge of the dietary habits of B. antiquus during the Late Pleistocene.

“…In the Río Tejupam locality (Figure 1), within the Tejupam municipality, an H. francisci basicranium, as well as several E. conversidens and E. mexicanus specimens were collected from fine-grained silty sand and silty clay beds 25 cm thick (Jiménez-Hidalgo et al, 2011). Organic matter from the silty clayey sediments was dated by AMS returning an age of 19,584-20,180 Cal BP.…”

Equids are among the most common mammals found in faunal assemblages of Late Pleistocene age in Mexico. Much of what is known about the Equus species is the result of studies conducted in central and northern Mexico; much less is known about species in lower latitudes of Mexico. Here we describe three species that inhabited Oaxaca and Chiapas states. The fossil localities are in northwestern and central Oaxaca, as well as the central part of Chiapas. In Oaxaca, the largest species, Equus mexicanus, and the medium-sized Equus conversidens are represented by mandibles, skulls, diverse isolated teeth and some postcranial bones, while the smallest species, Haringtonhippus francisci is represented by a skull fragment and few isolated teeth. In Chiapas, E. mexicanus is represented by a mandible and several isolated teeth, E. conversidens by several mandibles and diverse isolated teeth, and H. francisci by isolated teeth and two mandibles. AMS radiocarbon and uranium dating of some of the equid localities in Oaxaca and Chiapas indicate that they were at least present since ∼44,000 Cal BP years, they were common around 30,000 Cal BP years, and were still present at the end of the Pleistocene, around 12,000 years ago. The record of H. francisci from Chiapas is the youngest in North America. A cluster analysis of extended mesowear data and a discriminant analysis showed that Equus conversidens from Chiapas was obligate grazer, whilst the rest of the equids were variable grazers. Geographic distribution of localities in southern Mexico indicates that during the Pleistocene the equid species moved across the Transvolcanic Belt-Sierra Madre del Sur temperate biogeographic corridor and the Tamaulipas-Central America Gulf Lowlands tropical corridor.

“…El estudio de las faunas correspondientes al Rancholabreano contribuye al entendimiento de la fundación del Holoceno y de la respuesta de las comunidades de mamíferos al cambio climático (Arroyo-Cabrales et al, 2008). Las faunas del Pleistoceno tardío en Oaxaca corresponden en su mayoría a la región de la Mixteca alta, localizada al noroeste del estado (Pérez-Crespo et al, 2008;Jiménez-Hidalgo et al, 2011) y a la región de los Valles Centrales (Pérez-Crespo et al, 2008). En este trabajo presentamos el registro más austral de Bison latifrons, su fauna asociada y el análisis de dieta de un ejemplar de mamut, procedente de una nueva localidad fosilífera del Rancholabreano en los Valles Centrales de Oaxaca.…”

We report the southernmost record of Bison latifrons in North America. This is the first record for the species in Oaxaca (Mexico), and for the Transmexican Volcanic Belt morphotectonic province; the known geographic distribution range of Bison latifrons is extended in more than 447 km, from Tequixquiac in the State of Mexico to central Oaxaca. This finding comes from a new fossiliferous locality at the municipality of San Dionisio Ocotepec, located in the Central Valleys region of the state of Oaxaca, Mexico. The associated fauna includes: Mammuthus columbi, Equus cf. E. conversidens, and Bison sp. By the presence of bison as well as mammoth, a Rancholabrean land mammal age (Late Pleistocene) is assigned to the fossil fauna. In addition, we performed a proboscidean mesowear analysis as well as a low magnification microwear analysis (35x) to the dental elements of the mammoth. Our findings suggest that the mammoth individual was a grazer. Due to the mammoth's feeding habits and the habitat described for Mexican samples of bison and horses, we concluded that during the Late Pleistocene, San Dionisio Ocotepec was dominated by open grassland in the lowlands. This new fossil site and its fauna contribute to improve the knowledge of the Rancholabrean in southern Mexico, and particularly in the Central Valleys of Oaxaca. This improves our understanding of the biotic and climatic changes during the foundation of the Holocene.
