Looks like I'll kick it off this month! Aphelaspis Brachyphasis multi-slab Cambrian Conasauga Formation, roughly 500 MYA Chatsworth, GA Found: Saturday, February 3rd My favourite find from my recent 4th trip to the Conasauga for GA Trilos (and it was the first of the day, believe it or not). Overview: Aphelaspis Frag cluster: And the icing on the cake: Probably the best preserved Aphelaspis positive I have ever gotten from this site, even having clearly visible eyes!

Hello, and a very warm welcome to TFF from Morocco. My favourite fossils from Georgia have to be my Conasauga trilobites Aphelaspis brachyphasis and Barrandagnostus inexpectans.

It was that time of the month again, when I just had to scratch that fossil hunting itch. After the relative disappointment the other week in Floyd County, I decided to go ahead and pay another visit to my all-time favourite site in Chatsworth. When we got there this morning, it was obvious that the Conasauga river had greatly receded since the last time we saw it. In fact, it was the lowest it's been for more than a year (back in Feb. 2018). River on my last visit (Feb. this year): The river today: And a view from river bank: With how low the river was, I had a greater range of movement than I've had for more than a year's worth of visits to the place as a result. This also meant I had a lot more places to find Trilobites! And the Aphelaspis specimens I found were definitely worth the trip! To be continued

The Bolaspidella zone is exposed in many places along the old continental shelf of Laurentia (the tectonic plate that forms the original core of North America, without all the accreted terrains), including Utah (the famous Elrathia kingi-yieding beds of the Marjum Formation), Texas, northeastern Alabama, nearby Tennessee, and northwestern Georgia. Everywhere the same genera of trilobites are present, although the species are different. So, you can find Elrathia, Asaphicus, Peronopsis, and other trilobites in all these areas. In parts of the Conasauga the preservation of the trilobites may even look much like the Utah trilobites, i.e. preserved on calcite (cone-in-cone) wafers. Don

A word of caution about the possible age of the specimen: there is a lot of Middle & Upper Cambrian Conasauga Formation shale with chert nodules in the Coosa Valley area, but Rome itself is geologically very complex with Ordovician, Mississippian, and Pennsylvanian. All the Paleozoic formations, with the exception of the Lower Cambrian Rome Formation, have a large amount of chert. It's always a bit of a risk guessing provenance based on a photo, but the appearance of the specimen looks like a chunk of chert from the Mississippian Fort Payne Formation; at least, it does not look anything like the solid smoothly rounded chert nodules from the Conasauga. It also does not look like the massive black cherts that characterize the Ordovician formations in the area. That being said, the identity of the fossil is a bit of a mystery to me. It does not really look like trilobite pleural lobes, and the dimensions are much larger than the local species. Don

A possibility is Alokistocare americanum (Walcott 1916). The large number of thoracic segments and tiny pygidium is consistent with that ID. The species occurs in the Conasauga Shale at localities around Weiss Lake AL as well as in nearby Georgia. Schwimmer (1989 Journal of Paleontology 63:484-494) redescribed the species and synonymized numerous species described by Resser. The figure is from Resser 1938 and shows Acrocephalops nitida (20) and Acrocephalops insignis (28, 29), both species considered identical to Alokistocare americanum by Schwimmer. One issue that has led to oversplitting of trilobite taxa in the Conasauga is type of preservation: trilobites can occur flattened in the shale, partially flattened on calcite cone-in-cone wafers (the same way Elrathia kingi is preserved in the Wheeler Shale), or fully three-dimensional on or in chert nodules. Flattened shale specimens can have proportions significantly different from uncompressed chert specimens, and Resser was notorious for basing species on these sorts of taphonomic differences. Don

Hate to say it, but the clock has been ticking on this site since people started posting detailed directions here in the Forum and elsewhere on line. I said a few years ago that the site is small and cannot withstand a lot of collecting pressure. Now it is off limits, and there is no replacement that compares in terms of ease of access or abundance of trilobites. Also it was the only site to expose that particular part of the Conasauga and that particular assemblage of trilobite species. Don

Hello everyone, I was able to make a run down to the Conasauga River trilobite hunting site yesterday that was suggested to me in another thread. I didn't have an overabundance of time, but within five minutes of arriving, I found the specimen in the attached photo. It's not perfect, but it's the first time I've ever found a fossil out in the wild. Thank you to everyone for pointing me in the right direction. Now, since my time was a bit limited, I collected a five gallon bucket of the mudstone found there to look through it later. Now, some pieces seem easier to split than others. I've read on here that some people will soak items like this in water for about 15 minutes before attempting to take it apart. Does that sound right? I just want to have a chance at finding something else and minimize the risk of ruining a fossil in my quest to find one. Thank you, -William

Wow, everyone has been more than helpful so far. As far as the Lula Lake Land Trust goes, they do an Open Gate Day about every month. It requires a reservation and parking fee as they don't want the property to get too crowded nor loved to death. I don't know if an OGD reservation also applies to looking at rocks from the mining operation, so it'll be interesting to hear about meargleschmeargl's trip with PAG. I went to school with some of the family who are responsible for putting the Land Trust together, so they open it up for alumni who are in a reunion class on homecoming weekend. One of the waterfalls is a pretty easy walk, but the bigger one is a pretty challenging near-vertical hike. Worth it, but my knees felt the burn last time I went down to see it. I also remember going up to a bluff that overlooked a good portion of the valley below. There's something to be said about places like that that don't have guardrails. For those who might be content to look at fossils that are in situ and illegal to remove, Chattanooga's National Cemetery is a good place to look. Now, I don't yet know all the particulars other than to say the place has a good many limestone outcroppings, one of which contains a cave that's inaccessible to the public at this time. It's a good place to visit if you like history as its establishment goes back to the Civil War. There's also a WWII-era German general buried there. If I can get my math homework done, I might make a run down to the Conasauga River site and see what I can find. That would be a fun way to get started, and then later plan a Dalton brachiopod adventure. Thank you again for your generous assistance. -William

@Nimravis Would also be able to provide some locations, as I know he's been to the spots I frequently hit. Easily my favorite spot in that general area is the Conasauga formation in Murray county. There are plenty of Cambrian trilobites to go around, and from what I can tell it's a pretty popular site. If Silurian brachiopods are more of your thing, Dalton is the place for you. You go up the mountain just to the west of Dalton on the road that passes over the interstate, you'll come across a cliff face to your right that produces nice brachiopod plates from the Silurian-age Red Mountain formation. In GA, the most recent spot that I learned about is a place where you can find Pennsylvanian (Pottsville Fm.) plants in abandoned coal operations to the east of Trenton and Cloudland Canyon State Park, but the spot in question is owned by the Lula Lake land trust, and as of now I don't know a good way of contacting them. I will be going there for the first time tomorrow morning with PAG (Paleontology Association of Georgia), so I'll ask for contacts and whatnot surrounding permissions when I get there. I've also been to a Missisipian marine site in Tennessee proper where I've found some nice horn corals along with many (MANY) crinoid bits near Parker Gap along E. Brainerd Rd. If you talk to the owner or his taxidermist nephew (maybe son, I don't remember off the top of my head), they should be open to letting you hunt the quarry area on their land. I'm sure there are more sites, particularly Ordovician in age around the Chattanooga/NW GA area, but these are the sites I've been/am going to that I can confirm do indeed exist and are viable. Hope this helps!

Man, if only stuff this good was a short walk away! As much as I love Conasauga bugs, it wouldn't beat a backyard site, especially one pumping out goodies like these. So I know Terataspis grandis is rare, seeing the absurd hype surrounding it (and malcom stating there's only ever been 2 whole ones found), but what are the number stats for finding any evidence of these guys, just to have a ballpark figure?

Is that I-75 spot also Conasauga? What have you found there? Also, where would it be (pm)?

The site is one of my favorites....there is also a site on the western side of I-75 in a degrading hillside that I try to cover when I am at the Conasauga site. One of my very best display fossils ( one of the few on a stand) comes from that site. And it is such an interesting place to think about the thousands, perhaps millions of trilobites in that bank...all being covered by layer after layer of silty clay . the mudstone itself is a marvel...splitting so smoothly and creating such interesting layers....I have heard the deposit runs under the riverbed to the other side as well, and have often wanted to look on the opposite side of the river, but it always seemed too high when I was there. Low enough to collect, but too high to wade across...lol. And like others, I'll say, enjoy College Life. I hope it turns out to be even better than you expect.

Last entry before college! GCSU hype! Date found: 8/12/19 Name: Aphelaspis brachyphasis Trilobite split with dual-sided plate Geologic age/Fm: Cambrian Conasauga Fm (~500 MYA) Location: Chatsworth, GA One of the better packages I've gotten in just 1 split. Dunno if this would be good as one entry, but I'm entering the flip side of the positive slab with the split since it's on the same slab.

Extant Lingula next to Cambrian Lingula (from Conasauga Shale of Georgia)... Wow. Sure nuff looks like a living fossil, don't it? (he snickers and dashes for the nearest door...) ____________________________________ And here's an Obolidae from the same layer in the Cambrian Conasauga Shale...

Today, I decided to stop and see what @MeargleSchmeargl left behind at the Conasauga River trilobite location. I do like collecting at this Cambrian site. It is not a matter of finding trilobites, it is deciding which pieces you want to keep. I only spent about 1 hour there and did not collect any matrix, I just felt like splitting some pieces and finding a few trilobites. Nothing special was found and they we’re all Aphelaspis brachyphasis. As stated in @MeargleSchmeargl post, the River was low and the matrix was dry, thus making it very easy to split. I have only seen the River lower than today on one other occasion. When it is low, it is easier to maneuver and find a place to get comfortable. Here are my finds from today- this is the least amount of trilobites that I have found, but it because it was just a quick stop and I was taking my time. Here is my favorite find of the day- Here are some others-

I'll add another Trilobite to the mix. I'll see if I can get some better pics in down the road, as well. Aphelaspis brachyphasis trilobite 4/28/19 Late Cambrian Conasauga Formation (~500 MYA) Chatsworth, Georgia Positive: Negative:

Yeah, the Conasauga rocks are really nice and colorful.

This is the hash slab I bought with some Agnostids and Elrathria: And this is the Barrandagnostus inexpectans that I found last week up in Chatsworth. Probably my most proud find in the Conasauga shale:
