Well, It's been a while. After a hiatus that has seemed like forever, my friend Barrett and I decided to head to the Conasauga to find us some bugs as neither of us really had anything to do this weekend and we both wanted to do something. This was Barrett's first time, so I was effectively his mentor for the day. First stop however, breakfast of southern hospitality at a local biscuit place! After that, we went right to the site, getting into the nitty gritty. The river wasn't flooding over, but it was pretty decently high. Of course, that wasn't stopping us. We got into our big water-proof boots and jumped right in. Barrett quickly got into the groove, finding a certain section of the formation that was producing very large and complete Aphelaspis Brachyphasis with just about every swing of the hammer and chisel. Then late into the day, I found THIS beauty: I was stunned. I had never seen an exoskeleton on a positive that complete from the formation before like this, and for a second I thought it was fake. (sidenote, while transporting it to the car not long after this picture, a portion of the tailshield's exoskeleton unfortunately got peeled off by a very light breeze into the wind. At least I got a picture! Very fragile!) There was also a negative, though honestly it was completely outshown. In the end, we didn't take a whole lot, but we definitely took a number of really good ones, including some of the largest complete Aphelaspis I've seen.
Well I did not have much luck opening Mazon Creek concretions today, so I figured that I would try something about 190 Million years older, so tonight I was whacking Conasauga shale matrix from Murray County, Georgia, looking for Cambrian Aphelaspis brachyphasis trilobites. I did not go through much matrix tonight, but I did find a few trilobites, but the ones that I found do not represent the quality of trilobites that come from that location. As I continue to go through this matrix, I guarantee that I will find some pretty specimens and I will post my finds. Here is what I found tonight-
As you are all probably aware, I have been to the Chatsworth Conasauga exposure multiple times, and have gotten some stellar stuff from the formation. Recently, I have been seeing a lot about another exposure of the Conasauga in Floyd County near Rome somewhere along the Coosa river that produces a different trilo species (Elrathria Antiquata), as well as a species of primitive sponge, Brooksella (which I have yet to get, or any sponge material for that matter). Any tips on Floyd's Conasauga material? Brooksella, my primary interest: Elrathria antiquata, another objective:
Hello, all. After my last wonderfully successful Id effort on here, i thought I'd try again. This specimen was boshed free of some matrix that was sent to me by the unrivalled Ralph @Nimravisin a batch of matrix from the Conasauga Formation, Upper Cambrian, Georgia, USA and home to a multitude of the trilobite Aphelaspis brachyphasis as well as rarer agnostids and other even rarer trilos. I was looking at this paper https://www.researchgate.net/publication/250083071_Exceptional_fossil_preservation_in_the_Conasauga_Formation_Cambrian_Northwestern_Georgia_USA and thought my specimen below looks rather like the example D in Figure 3 (sorry, I don't know how to just post that image. It's a chlorophyte, so is mine ? They appear to be sort of tiny strings of sausages, the longest string being about 2 mm long, so each individual 'cell' is very tiny indeed. Thank you for any comments, ideas or suggestions. Adam.
