My pleasure !
I happen to live on a salt marsh behind a beach that is famous for whale strandings ; one such event even made Time magazine back in the eighties ; I believe a hundred or more Pilot Whales came ashore at that time . That particular vertebra was from a far older stranding ; I found it while walking the marsh .
That is a small example ; a Spermacetti sized one would make a good stepping stone for a walkway .
The smooth surface is just that , a surface ; underneath it is a honeycomb of pores , and it still stinks a little after more than 30 years .
