Sample sizes by taxonomic group for all specimens and subsets of specimens by available skeletal material. Skeletal specimens did not always preserve a pisiform, calcaneus, and dentition. Data were collected from specimens with at least two of the three skeletal elements and recorded into data subsets based on the material present. Individuals were included in all data subsets for which material was available.
