Who can tell me what’s inside?

Awesome she’ll imprints

*shell

Ausome fn finger prints

Lols human made

Grab a price of clay not to moist roll it into a snake if you don’t wet it and smother it out it will leave fingerprints palm prints face plants etc

I agree seems to be shell imprints

Definitely shell imprints on outside but there is some skeleton like remnant encased it shows at one end and halfway down the rock
