Herein I plan to post pics of my modest collection of Mazon Creek fossils, but first a question.
I found this nice little map in a paper by LoBue (2010) of the general Mazon Creek area, showing the location of the numbered mines/pits. Could any of you who know the area and the fossils explain in a nutshell which areas produce the Essex Fauna and which produce the Braidwood Fauna (or flora - maybe I should say 'Biota')? I know Pit 11 is the main source of Essex fauna (Essexella etc.), but is it the only place Essex fauna occur, and those other pits produce only Braidwood biota? Are they relatively exclusive of one another or is there some crossover? I work best with maps, so if anyone can annotate the map to make things clearer, please do. Also I'd like to know where the county lines are on this map.
In the following fossil pics, I have incomplete info as they all came from dealers, auctions and such, I've never been able to collect the site myself, so the info I receive is typically incomplete and sometimes wrong. If anyone could narrow down any of the location info for any of the fossils, I'd appreciate it, and please correct anything that is incorrect!
