Very prominent eyebrow ridges on that skull. Meaning what, I don't know. We visited the pre-historic dig in Mitchell SD and found it very interesting. Those people were unrelated to the Lakota in any way. GD
Very prominent. Frontal cranium appears sloped with not a whole lot of skull above the eyes. If found in a river it would be doubtful death occurred where the skull was found. Water flow, flood level water flow, kept as a souvenir then discarded, on & on. Officials who surrendered the skull are idiots. Lots of data to be gathered there telling us a lot about human migrations.
