Data from: First 87Sr/86Sr Isotope data for the extinct sloth Lestodon armatus: Insights into the spatial ecology of South American Late Pleistocene Megafauna

This dataset provides comprehensive data for understanding the spatial
ecology of the extinct giant ground sloth, Lestodon armatus, during the
Late Pleistocene in Uruguay, South America. The research context focuses
on elucidating mobility patterns and landscape use of this species through
strontium isotope analysis. The dataset includes raw 87Sr/86Sr isotope
values obtained from L. armatus bone and dentin samples collected from six
distinct localities in Uruguay, including data from six individuals and
serial sampling of one tooth from one of the sampled sites. Users can
utilize these data to replicate the findings of Varela & Fariña
(2025), which showed highly localized 87Sr/86Sr signatures, suggesting
limited movement and defined home ranges for this species, and ruled out
extensive seasonal migrations. Included are all 87Sr/86Sr isotope data and
the R script (script.R) used for statistical analysis, generation of
figures, probability-of-origin surfaces, and home range estimations
presented in the original study. Also, the dataset contains habitat
suitability and resistivity raster files, as well as a .ini configuration
file for executing the Omniscape analysis in Julia to explore landscape
connectivity in southern Uruguay during the Last Glacial Maximum. This
dataset offers a valuable resource for researchers studying Quaternary
paleoecology, megafauna mobility, isotope geochemistry, and landscape
connectivity, providing a baseline for the spatial ecology of South
American megamammals.
