Postcanine dental metrics for hominin fossils from the Omo, Ethiopia, and the comparative dataset

These are data that were analyzed for the taxonomic assignments for the
3.75 Ma to 1.09 Ma hominin postcanine teeth from the Usno Formation and
the Shungura Formation, Lower Omo Valley, Ethiopia. The dataset includes
the linear dimensions, the morphological scores, and the 2-dimensional
occlusal areas of the postcanine teeth from the Omo. We also include the
linear dimensions (mesiodistal and buccolingual dimensions) for the
comparative sample (hominin fossils that provide important taxonomic
context) that were primarily culled from the literature.
