Description of dataset These data were generated to compare body size and paleolatitude in Lystrosaurus from four tectonic basins that host Early Triassic strata. 482 specimens were measured by Zoe Kulik or compiled from the literature. Cranial measurements, including basal skull length (BSL) and tusk diameter, were used as body size proxies and are reported as raw and standardized measurements. Measurements were standardized as percent of maximum known size for each species, respectively. Paleolatitude was estimated from tectonic plate reconstructions made available through the online calculator www.paleolatitude.org. Please contact the corresponding author for further details (zkulik@uw.edu). File List: File Name: KulikSidor_BRSupplement File Description: Species identification, raw and standardized cranial measurements, and geographic location of specimens included in this analysis. Number of variables: 9 Number of rows: 482 Variable List and abbreviations used: Species: Species identification Accession Number: accession number for each catalogued fossil specimen, or currently uncatalogued fossil specimen included in this study. Uncatalogued specimens are denoted by their respective museum code (e.g., uncat AMNH) BSL (mm): Basal skull length measured in millimeters Std.BSL: standardized basal skull length as the proportion of species-specific maximum known size, or percent of maximum known size reported for each species of Lystrosaurus included in our analysis. Tusk Diameter: diameter (in millimeters) of tusk at eruption from the maxilla. Values were averaged when both tusks could be measured. Std.Tusk: standardized tusk diameter as the proportion of species-specific maximum known tusk size, or the percent of maximum known size reported for each species of Lystrosaurus included in our analysis. Paleolatitude: estimated paleolatitude Basin: geographic location of fossil collection Reference: Citation information for cranial measurements that were compiled from a survey of the literature METHODOLOGICAL INFORMATION Cranial measurements were taken using Mitutoyo digital calipers (±0.02mm).
