A combined mesowear analysis of MexicanBison antiquusshows a generalist diet with geographical variation

Abstract: 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 Cint… Show more

“…Then, we ran a second analysis to predict the feeding group of the studied specimens. We used the linear discriminant method and common covariance as the data were of the same order of magnitude and were in covariance (Díaz-Sibaja et al, 2018b). Dietary category was the grouping variable (obligate grazer, variable grazer, mixed feeder, and browser).…”

“…Previously, both species were recovered from sediments that are around five meters above a 49,724 ± 2,074 Cal BP dated bed in Huexoyucán, Tlaxcala, in central Mexico (Tovar et al, 2013;Sánchez Salinas et al, 2016). Equus conversidens, E. mexicanus, and E. cedralensis have been recorded in sediments of around 24,000 Cal BP in La Cinta-Portalitos, west-central Mexico (Marín-Leyva et al, 2016;Díaz-Sibaja et al, 2018b), and they were also collected in beds bracketed by dates of 37,694 ± 1,963 years BP and 21,468 ± 458 Cal BP in Cedral, northern Mexico (Alberdi et al, 2014). Additionally, E. conversidens was recorded in strata having an age between 11,000 and 27,000 Cal BP in San Josecito Cave in northern Mexico (Arroyo-Cabrales et al, 1995;Arroyo Cabrales and Johnson, 2003), and it also has been collected in sediments that are three meters above a bed dated in 34,512 ± 220 Cal BP from Santa Cruz Nuevo, Puebla state, central Mexico (Tovar et al, 2014).…”

“…Para esta área se reconocen seis facies litológicas y paleontológicas: Facies I, fluviolacustre, arcilla con arena, energía media y alta; Facies II, volcánica, arena, energía media; Biofacies III, micro y macro-conglomerados, alta energía, con fósiles de macrovertebrados; Facies IV, arena y limo, energía media y alta; Facies V, lacustre, arcilla y diatomea, energía baja; y Facies VI, suelos, arcilla y limo, energía baja (Marín-Leyva, 2011; Marín-Leyva et al, 2016a, 2016b. En esta área también se tiene la presencia principalmente de carnívoros (Canidae), perisodáctilos (Equidae), cetartiodáctilos (Bovidae, Camelidae) y proboscidios (Elephantidae) (Cervantes- Barriga, 2015;Díaz-Sibaja et al, 2018;Gutiérrez-Bedolla et al, 2016;Marín-Leyva et al, 2016a, 2016bPlata-Ramírez, 2012).…”

“…Desde un punto de vista ambiental, los análisis de dieta meso y micro desgaste, así como los de isotopos estables de 13 C y 18 O de Mammuthus columbi, E. cedralensis, E. conversidens, E. mexicanus y Bison antiquus en la localidad LC-PT, muestran la existencia de plantas con componentes altamente abrasivos. Estas incluyen gramíneas o pastos (C 4 ) y elementos vegetales medianamente abrasivos como: árboles y arbustos (C 3 ), por lo que para este yacimiento existía un medio heterogéneo con ambientes cerrados (bosques) y abiertos (pastizales) (Díaz-Sibaja et al, 2018;Gutiérrez-Bedolla et al, 2016;Marín-Leyva et al, 2016a, 2016b. En el caso de LP-SA los análisis de dieta meso-micro desgaste así como los de isotopos estables de 13 C y 18 O en Mammuthus columbi, E. cedralensis, E. conversidens, E. mexicanus, Bison antiquus en la localidad, muestran la existencia principalmente de plantas con componentes altamente abrasivos como las: gramíneas o pastos (C 4 ) y en menor proporción elementos vegetales C 3 , por lo que se deduce un ambiente heterogéneo pero con una mayor dominancia de ambientes abiertos (pastizales) con relación a los cerrados (bosques) (Díaz-Sibaja et al, 2018;Gutiérrez-Bedolla et al, 2016;Marín-Leyva et al, 2016a, 2016b.…”
