Super neat. In North America we share the style of portable rock art. Citizens from all over the world are sharing their finds* and collaboratively researching.

Why was Northern Bronze Age rock art (Scandinavia) not referenced? Its style reflects much of the common features of Atlantic littoral. But your study is very useful data and much appreciated.

Great lecture. Is there a correlation between finds of carved stone balls?
