Mobility studies in fossil mammals from Laguna de las Cruces, San Luis Potosí, México: The strontium isotopic analyses

摘要: Abstract Strontium isotopic ratios from dental enamel of fossil camels, Camelops hesternus (n=5), horses, Equus sp. (n = 5), and mammoths, Mammuthus columbi (4) Laguna de las Cruces, San Luis Potosi, central Mexico, have been used to study their migration behavior. Four all one mammoth display 87Sr/86Sr similar local plants soils, thus identified as residents. In contrast, teeth camel two mammoths show lower while has higher strontium that indicate they migrated other localities. Oxygen isotopes resident animals are similar, which suggests those individuals drank water the same source, whereas δ18O values migrants different, confirming data findings. However, yet, it is not possible determine where came because different soils Potosian Zacatecan localities with were compared.
