Ancient Native American Pottery? Parts Pieces Salvaged South Carolina Lot Broken

Description

Ancient Native American Pottery? Parts Pieces Salvaged South Carolina Lot Broken. Condition is Used. Shipped with USPS Priority Mail.
Found in a collection of fossils I obtained from a hobbyist from South Carolina. After showing them to a dealer of fossils and rocks, their best guess that this is pottery and early pottery likely Native American. 1 piece does appear to be bone, possibly an animal skull fragment.  I am not an expert in such things.  Please see all photos.  Will be shipped with care to ensure they do no get damaged from their current condition.
