Found this cool complete little bone while screening some gravel in a Summerville creek. Seems familiar but not enough to hazard a guess. Thanks for looking!

Okay, I posted this yesterday and I’m not sure if it was that it was too long winded, in the wrong spot, or both. So, I will attempt to boil it down. There was a post on this topic in 2011 but I feel like there’s certainly more knowledge on this now. 1. What formations are megalodon teeth coming from? The plausible ones are the Parachucla (22ma), Marks Head (18ma), and Goose Creek Lime (3.5ma), all within the umbrella Hawthorn formation. The CofC Museum lists almost every specimen as coming from the Goose Creek Lime, yet the hottest spots at best have the Raysor formation(2.5ma) exposed. 2. Are said spots only good underwater where the river has cut through to the former three? 3. Is material between the Marks Head and Goose Creek era extant in any areas? People have suggested that the size of some teeth would place them in the middle of these two time periods, unless there’s reason to believe they’re reworked. 4. Wanting to see pictures of the formations mentioned (excluding Marks Head which is only subsurface), in addition the Wando and Chandler Bridge formations if anyone has pictures lying around.
