@Diverdude76 8 May 2021 more from that month

Well I thought I would go ahead and post something I know something a little about. Here's my fossilized whale inner earbone I found last month while diving all cleaned up from crustaceans. Soaked in vinegar for about 45mins. Before and after pics. You can also clean fossilized shark teeth this way, but for no longer than 45mins soaking in vinegar or you run the risk of damaging the enamel on them.
