01 July 2015

More stone birds and burins typical for Arkfeld Site uncovered on May 26 dig are like those identified at Flint Ridge, Ohio, and other sites

Flint Ridge, Licking County, Ohio, bird figure featured in an earlier posting is made on the same semi-formalized scheme or template as the Arkfeld Site limestone bird. This demonstrates a suspected Stone Age Eastern North American cultural imperative to create similar bird figures despite vastly different locally available stone resources.

Flint Ridge, Ohio, diamond-shaped burins found with bird figures just like at Arkfeld Site. Ohio chert version at left and Ohio limestone version at right.
