Strontium isotopes and mobility of a Columbian mammoth (Mammuthus columbi) population, Laguna de las Cruces, San Luis Potosí, México Article uri icon

abstract

  • By using strontium isotopic ratios of dental enamel from molars, we were able to reconstruct the migration context for three individuals of a Columbian mammoth population (Mammuthus columbi) around Laguna de las Cruces, San Luis Potosí, central México. A three-step leaching procedure was applied to eliminate secondary Sr contributions in the molar enamel. One of the studied individuals showed 87Sr/86Sr ratios similar to those obtained from soils and plants from Laguna de las Cruces and was identified as local, whereas the other two mammoths had different molar 87Sr/86Sr values, indicative of migration and mobility contexts. ©Cambridge University Press 2016.
