Extremely RARE Karankawa (extinct Tribe) Pottery Shards Native American Artifact

Description

These were picked up on Galveston Island land belonging to John Egert, Sr., sometime in the 1960s or before. They were discovered by his granddaughter Anne Meussig, who was an amateur archeologist in Texas - and me. Anne was my mother, and we often went digging for Karankawa artifacts on the family's land.
These are pieces or shards of Karakawa pottery. They were a small tribe that lived only along the Texas Gulf Coast. This tribe's population is unknown, but it was quite small. Unfortunately, the last of the Texas tribe on Padre Island was wiped out by colonists in the mid-1800s. See Wikipedia for more information about this extinct tribe of Native Americans.
Since this piece was found on Galveston Island, and the tribe fled from there to Padre Island in 1825, it is at least nearly 200 years old.
The Karankawa did very little embellishment on their pottery other than some ridges. One of these pieces shooed that. Their pottery was difficult to make due to the high sand content of the soil.
