Bird stone

[1] The exact purpose of these artifacts is not known, but most have a small hole drilled at the base of the neck and another at the aft end, presumably for mounting.

A new theory recently arising from an amateur archaeologist focused on Native American fiber processing, is the bird stone was a tool used for mat-making and weaving.

The smooth surface of the stone is perfect for flattening fibers without breaking and the beak feature used to push reeds together.

[2] It has also been suggested that these artifacts were worn as decorative items denoting marriage status or pregnancy,[3] and as totems representing tribes.

[4] Bird stones were mostly made east of the Mississippi, and the thousands in existence have been found primarily in New York, Ohio, Michigan and Wisconsin.
