  1. From the very moment we wrapped up at that Conasauga Formation fossil hunt at the spot I'd never heard of before, I was itching to get back there. I guess that's what going for years without hunting half-billion year old bugs does to you. Well, this past Sunday I had my opportunity to get another bug hunt in. It's a good thing I brought my water boots with me, because the spot was quite a bit wetter than the previous time I had come, with some really large puddles at the foot of the hillside I'd get to work in. After a good while of splitting, I had myself yet another selection of Conasauga trilos Of the specimens I collected this time around, I picked up some really interesting and precarious pieces, most notably this one: If this was all there was to this Aphelaspis plate then it'd be a really nice find, but it wouldn't have controlled my attention in quite the way it would have if it didn't also have this: Apparently when this piece split, it split into 3 pieces, not 2, with the 3rd piece actually being the exoskeleton of the larger individual in the split. How it hasn't broken/crumbled into a million pieces by now is beyond me especially considering how thin it is, though I'm definitely not sure how I want to approach it as a result. I'd love to be able to bring out the rest of the detail in it, but with how fragile I know these exoskeletons to be, I'm not even sure it's possible to do much of anything, at least not with what I have on me. It goes even further too, as on the opposite sides of each of the main 2 pieces, there's another 2 trilobite individuals, one on each plate! The split that keeps on giving, that's how it tends to be with this Conasauga material, even when you're splitting at home! With that collective piece, I think I'll nickname it "Frankenbug". Will definitely be open to ideas on how to approach it! As for the rest of my finds, they may not be quite as remarkable as the piece above, but as per usual you get all your Conasauga Cambrian goodness!
  2. If you have ever looked through my post history on this forum over the years, you'd know that the Cambrian age Conasauga Formation has been one of my favorite formations to hunt, being the best formation to hunt for trilobites in the state of Georgia that I know of. Unfortunately for those of us that came to enjoy the abundance of trilobites the formation provided, the main site in Murray county that had become widely known by the time I had visited it a few times had attracted some...shall we say...less than intelligent guests to the area, resulting in the site becoming fenced off. For quite a while now I'd been trying to find another good exposure of the Conasauga to search. While I was able to find mentions of exposures further west in Floyd county in the literature, my scouting trips to see what was there up to this point have been swings and misses. Cue me receiving an email from my local paleo association (Paleontology Association of Georgia for any interested in joining) that we were going on a field trip to hunt for trilobites near the Resaca area. I looked it up, and while I ultimately found one other mention of a separate group going there, I have yet to find literature mentioning the site, and it was quite a bit further south than I was expecting a Conasauga exposure to be (if anyone has said literature, I'm all ears). As you could imagine, I'm pretty excited to learn of a new exposure to a favorite formation of mine. This past saturday, we met up in a gas station parking lot for a quick association meeting and then we were off. It wasn't too long of a drive until we came upon a roadcut that exposed that beautiful Conasauga goodness, an exposure that is much more easily accessible than the Murray site was. It wasn't very long before I spied the first find of the trip: Before too long I had struck a groove with splits in my little corner Here's a montage of what I found over the course of this little expedition. Not the most I've ever picked up from the Conasauga in one go, but it's definitely great to get back into the swing of things with this formation. As for IDs, my prior experience with this formation has me thinking Aphelaspis brachyphasis such as the many pieces I already have in my collection, though this exposure seems to have greater diversity in terms of species when compared to the Murray exposure, and admittedly distinguishing between Aphelaspis and Elrathia antiqua is not my strong suit right now. (I could also use some tips on how to clean some of them up, as some have a bit of gunk on them and I know that they can be pretty fragile)
  3. As my life in college is imminent (I head to Milledgeville Thursday), I wanted to fit in one last pre-college trip to my favorite bug spot (An idea that was really given life when I heard about a Schwimmer paper that got into PALAIOS about what may be the oldest nesting behavior ever discovered (https://www.georgiasfossils.com/new-2b-a-trilobite-nest-in-georgia.html)). I can say with confidence that yesterday scored in the upper tier of my trip list to the site. I arrived later in the day than I usually would (got there around 6:00 or something), and the river was once again quite low. As a matter of fact, I think it was as low today as I've ever seen it: I went to work right away splitting some slabs from one of the lower layers that seems to give me the best results, and before long, I was getting quality split after quality split. By the end of my relatively brief 1 hour stay, I had quite a few nice pieces to take with me: Cont.
  4. I just went to the Floyd county Conasauga at a roadside site mentioned in https://www.researchgate.net/publication/264495630_Taxonomy_and_biostratigraphic_significance_of_some_Middle_Cambrian_Trilobites_from_the_Conasauga_Formation_in_western_Georgia (partly guided by a few locals). After searching, we found tons of nodules, and only a few exposed Trilo parts. It was only near the end of the trip that I realized that at this site, I might need to split the nodules open to find much in them. So I took a few decent sized ones with me to figure out what to do with them after I attempted to split a few, and only getting one open relaitively cleanly (nothing inside). My immediate assumption is perhaps to use the freeze/thaw method I've heard people use for mazon creek nodules (instructions?). Any other tips for splitting these nodules? They're much tougher that I personally thought they'd be (at least it was harder to actively split them on site, given their round shape makes it hard to keep the chisel going in one spot). The site: Some of the numerous nodules present:

    Conasauga Crusade #7: Jackpot

    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.
  6. 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-
