Hello Crwncrk,Nice piece, definitely Native, and definitely a raised design. Likely stamped using a paddle. I’ll check my book for the exact pattern.
Also don’t feel bad about not reporting it, there are ancient trash middens ALL OVER the Florida coast. Most have or had potsherds in them.
I think this painting depicts the Calusa Kingdom in south Florida, but it’s quite historically accurate. They ate so many oysters that the oysters started having thin shells and system collapse. If you know the area well enough, you can roughly date a site based on how thick each shell is.
