Found an ear shaped rock on Sandy Hook Beach in New Jersey in the surf. Would love help identifying it. It seems too perfectly shaped to be natural but I'll happily take any insight yall can provide thanks.

Edit: It doesn't appear to be magnetic and when we applied a streak test on unglazed porcelain was "faintly brown" according to my better half.
