Hey hi Everybody! I like the unusual teeth. And posterior teeth are some of the most unusual in any given species. So I thought I would start a thread for posterior shark teeth of any species.   To kick it off..... Here are some from Shark tooth hill (round mountain silt). I think these are Carcharodon hastalis and (?) planus.   The smallest one is just under 1/8th inch wide.     So, if You have any posterior shark teeth - please post pictures here. Thanks, Tony
