Excellent discussion!

The subject is so obscure that resolution hinged on deep knowledge of the site, by experienced local collectors.

I love it when the magic works!

Totally agree. Fantastic discussion! We couldn't be sure if it was fish or crustacean or even poop or regurgitate.  Local knowledge and experience are so valuable and we all learn. Keep up the good work everybody.
