  1. You are correct about the Conasauga trilobites, but I am not sure about the brachiopods, maybe Tony @ynot might be able to answer that question.
  2. aren't crystals inside brachiapods cool. I have several also, as I was admiring yours, I started wondering why they form....is it because of the specialized chemicals in the soft body tissue that stays trapped as it decomposes inside the shell....or is it, that water with minerals leaches into the shell and with the space the crystals grow...in other words, I guess I am trying to figure out if the crystals grow inside because the shell is merely a fissure, or does the animal actually contribute to the process. In the Conasauga Trilobites found near Dalton, Georgia, most of them have a sort of iron looking blow ring around them, which I've read, is caused by the decomposing fleshy parts...one of the ways to distinguish between a molt and an enact animal. So I hope someone knowledgeable about such things provides an answer. Thanks. And great finds, especially the peripristis.
  3. 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.

  5. No better way to spend a sunny, 52 degree Georgia day than fossil collecting with my son. This is the first time in about 22 years that we have collected together. We went down to the Conasauga River in Murray County to collect Cambrian trilobites. Unfortunately the River was running high and fast and it did not make Collecting easy. I had to do some fancy climbing to get to the area that I wanted to collect. Using tree limbs to hold onto, I was able to navigate the slippery slope. I only took two pictures of partial trilobites that I found, I decided not to take any more pictures because I was worried about dropping my phone in the river. Here are some of my other finds- all Aphelaspis brachyphasis, with the exception of this first piece, I believe that this is a partial Eugonocare , I have only found one other partial one in the Times I have visited this site.
  6. fossil hunting

    Let me tag @FossilDAWG who knows Georgia formations more intimately. There are some good areas in your state. Have you been to the Conasauga shale yet?
  7. Conasauga Formation Trilobite ID

    Today I was picking through some of the matrix that I have from the Conasagua Formation from Murray County, Georgia and came across a trilobite that surprised me by its size and nice detail. Unfortunately, this trilobite is not complete, and from my limited knowledge of trilobites, it does not look like the Aphelaspis brachyphasis trilobites that i find from that location. Lastly, if it is an Aphelaspis, it must be one on steroids. Any help would be appreciated. @Kane , @sixgill pete , @Fossildude19 , @WhodamanHD , @FossilDAWG An Aphelaspis - on the larger size of what I find. Unknown:
  8. Opening Day For Mazon Creek Collecting at Pit 11

    wow. This place seems very interesting ! the Nodules look alot like the fossil nodules in the conasauga formation in Georgia! I would Love to go there and collect some. So this area is only open to hunt for a certain time of year? Or can you go there in the winter if theres no snow of coarse?
  9. Georgia Trilobites

    I did not think that I was going to have time to hunt Georgia Cambrian trilobites – Aphelaspis brachyphasis from the Conasauga Formation, but I did find a couple hours to collect. So this morning I left at 7 AM and drove one and a half hours to Murray County, Georgia to collect at a small exposure on the Consssuga River. It was a cold morning, 31°, even by my Chicago standards for October. The purpose for this visit visit was to gather some matrix for winter work. If you have a chance to visit this site, besides being abundant , many of your finds will have multiple trilobites on the mudstone. Below are a couple pics of the area, as well as some of the trilobites that I found.
  10. 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-
  11. December 2018 Finds of the Month Entries

    In loving memory of when this guy had a nearly complete exoskeleton (portion of the tailshield's exo flaked off at some point ), I'll start off inverts. December 15th, 2018 Aphelaspis brachyphasis Late Cambrian, ~500 MYA, Conasauga formation Chatsworth, GA Positive: Negative:
  12. Conasauga Shale

    Made it down to the Conasauga Shale as the last of 10 sites on a 4-state, 6-time-period collecting expedition in mid-august. I'll post reports on the other sites (as well as other trips earlier in the summer) later. I elected not to split shale on-site and just collected shale for splitting in a controlled environment. I'm only interested in trilobites that still have the exoskeleton (rather than just impressions). I gently tap the shale until I see a fine crack in a bedding plane and then carefully pry it apart with an Xacto knife. The exoskeletons usually have a hollow space above and below them and are terribly fragile. One must hope that all the exoskeleton ends up on one side of the split. Any still unexposed require tedious removal of matrix under a scope with a fine needle while trying to avoid poking through the exoskeleton into the hollow space underneath. I wick consolidant under the exoskeleton to prevent it from flaking off. Even blowing on it can knock it off. Here are the keepers.

    I have the same issue with my Conasauga trilo's in mud stone.  Easier for me as large chunks go into a bowl of water and in a couple of hours they turn into decks of playing cards.  Most cards can be separated by clever finger tips but some require the exacto.  Best of Luck.

  13. Georgia Cambrian Trilobites

    Well since it is snowing in the Chicagoland area (expecting 6-12” tonight), I decided to go through some Conasauga matrix looking for trilobites, here are my finds. I know that they are not the sexist trilobites, but I do love being able to cut thru the matrix with a hacksaw.
  14. Georgia Cambrian Trilobites

    Some bugs in this last set are nice and big, relatively speaking. I tried splitting some of my Conasauga matrix after soaking in water for a couple of hours, and the splits were even worse than the drier matrix. As a test, I soaked a couple of pieces for several days, and those split cleanly and easily yesterday. I'm now soaking more, so I'll see how they turn out after a few days.
  15. Roadtrip from NC to GA

    My final destination would be the Conasauga river trilos
  16. If you beautiful people recall, I said I'd be heading back to our favourite GA trilo site on the Conasauga river for my Convergence media project. Well, here's the run down: When we got to the small parking space that eternally marks the entrance to the site, we checked the river as we always do. To our fortune, the Conasauga was low Saturday, giving us more leg room to hunt. It was definitely the right condition to hunt! Not too hot or cold, and the river was nice and low. After doing some filming shots for the DEC (the school news program), I got to what was REALLY important: finding those trilos! I actually deviated from the norm this trip by going to the other side of the bridge, a place I haven't really explored before. And it was looking promising: It wasn't long before I found a direct formation exposure and got right to splitting the incredibly easy-to-split rock: A short 30 minutes later, I had already gathered a good trip's spoils... One particular multi-slab I found simply lying amongst the rocks caught my eye, with one Aphelaspis positive being practically complete, and even having visible eyes (more images coming later):
  17. Wow! A Great Trip!

    Kids are great. My son and I spent Saturday picking up rose quartz (100lbs) and some very deep blue translucent aquamarines. Conasauga next week.
  18. The mudstone from the Conasauga Formation in Murray County, Georgia produces a nice quantity and quality of the trilobite "Aphelaspis brachyphasis" (below). But when it comes to the Agnostoid trilobites, I have only found pieces, that is until tonight. I finally found a complete specimen, though the quality is not the greatest, it is complete.

  20. Well I was going to add on to my post from 2 days ago, but I just decided to do a new one since it is a second visit to Murray County, Georgia to collect Cambrian trilobites from the Conasauga Formation. Today was another great days in the 80’s and it is nice to collect underneath the bridge, since you are in shade the whole time. Since my brother had to work today, I collected by myself, as I usually do. If members have not seen the area from previous posts, I will add some below that I took today. Here is a view from on top, prior heading to the collecting site. The next view is looking up at steep climb to get back to the top. Here is the collecting area. And a view of the Conasauga River, it is very low. Here are a few of my finds from today, I like to take more pics, but since I do it in the field, and cutting pieces down to size, it takes away time from collecting. Aphelaspis brachyphasis Here is a a great piece with 7 trilobites. Some of the really little ones ones are preserved very nicely. I also collected matrix to take home so I can work on it in the winter.
  21. While visiting family in Georgia, I decided to take my older brother on a Cambrian Bug Hunt. There is no better place to go than a little exposure in Murray County, Georgia that lies under a bridge and next to the beautiful Conasauga River. The Upper Cambrian (Aphelaspis Zone) trilobites found here include Aphelaspis brachyphasis, and Agnostoids, among others. This is a relatively small exposure and depending on the height of the river, it can make the exposure that much smaller or not accessible at all. I was down her in May on my way back from Sanibel Island and I was not able to collect due to river conditions. The other thing that is small with this site is parking, if cars are parked correctly, you can fit 2, but no more that that. I also collect early and leave as much room as possible for any other collectors. Here are a couple pictures of the collecting area and the steep and often slippery descent. We were were only able to stay for two hours due to the fact that my brother got injured, but I will touch on that at the end. Here are some of my finds, I also collected matrix to work on later. Aphlelaspis brachyphasis Aphelaspis brachyphasis and a Agnostoid portion. Besides the mudstone, trilobites are also found in a harder grey shale. Here is a very large portion I found on the ground ( 35 pounds) and I will work on this piece at home. As you can see, there are trilobites found in it and many times they have excellent preservation. One handy tool to have there is this folding hacksaw, it allows me to trim pieces in the field for easier storage. As I stated above, my brother had an accident, really a slip and fall. Besides watching how you go up and down to your car, you have to watch the loose matrix. He went to adjust how he was sitting and the loose matrix caused him to slip. It appears he broke or dislocated his left pinky finger and we left so he could go to Urgent Care. Be careful collecting anywhere.
