I was thinking could be epoxy but not 100. Figured it was way to hard to be a sponge literally feels like a rock.Almost looks like it was fragged, the skeleton cracked and someone put a "cast" of epoxy putty over the break to hold the skeleton in place until it healed?
Otherwise, if it isn't a sponge then I have no other guesses at what I am looking at.
