This incised bird bone tube from the Windover Archaeological Site is now on display, Only five bone tubes were recovered and most were associated with female burials. Although, one was associated with a juvenile (sex indeterminate burial) Manufactured from cut sections of the upper arm bone of a large bird (possibly a pelican), three were decorated with incised patterns like the one seen here. This decoration could have been achieved using a shark tooth or chert engraving tool.
