This unusual artifact is ground all over, with a very smooth feel on both sides. This is a well defined example of a rarely found Texas artifact. It is made of a banded color limestone. Though the boatstone itself is only ever so slightly concave it was very purposefully polished to it's present shape. This artifact may have been used as a weight, designed to counter balance an ancient spear throwing stick known as an Atlatl. Boatstones are very rare in Texas.
