"What is it?" Wednesday!

Back for more? Let's try another, and this one is for a prize (best guess gets an FPAN travel mug, keep it clean though!)

This artifact was found in someone's yard in Clay County just southwest of Jacksonville. The homeowner reported finding it by a tree in her housing development (very new, very large development I should add). She imagined a Timucuan warrior resting beneath the tree who left this object. I did go out to take a look in person and aimed to fill out a site form. I have a pretty good working theory but before I share I want to hear from you:


WHAT IS IT???





(It was hard to see in the photographs he sent, but in person the top of the object did look like a man's bearded face.)



Bonus points if you can figure out why I didn't fill out a site form!!
