  1. I would love to learn from some of you regarding what species of nautiloids these are (maybe multiple species). They’re different than the larger ones I find more often in similar areas and I like the pattern detail visible on some of them. They almost always have a very distinct curve at the outer edge. These are mostly from 2 spots in burleson TX. The unusual nautiloid with lots of details visible and crystallized (looks brown in the photo) on the inside was from a different spot (maybe Fort Worth formation?) where I find mortoniceras ammonites.

    Jacksboro Hunt

    Howdy folks. Been a while since I’ve posted. I went through some significant personal losses and haven’t been on TFF in much longer than I’d have liked. After over a year, I’ve finally gotten out to hunt, this time in an area I’d never been to. (Also, if you’re in the Jacksboro area, my water bottle unfortunately fell out of my backpack, and I would really like to get it back since it’s been on a lot of trips with me. I’d pay someone to go get it if they’re nearby!) The weather was pretty nasty, raining and thundering a good amount of the time I was out hunting. But with new erosion, there was a lot of good stuff to be found. I will be updating this post with new photographs as I get things clean, everything is pretty muddy. IDs and information is welcomed, I am not familiar with Pennsylvanian material. A nice little Gastropod was the first thing to greet me. It was quickly followed by a straight nautiloid, which I found being one of my favorite things to pick up. Lovely bit of Goniatite. Probably my favorite thing to find here. Fresh whitetail deer tracks, probably only a couple hours old from earlier in the morning, right through the exposure. Held my breath for a moment, hoping this might be more whole, while it was, the condition is pretty poor. Still a nice find. The plains were standing in water about 3-5 inches deep across the entire area. In about a week, it will be an absolute nightmare! Tens of thousands of mosquito larvae.

  6. Hello and Happy New Year to all of my Fossil Friends! Yesterday and today I put in my first 2 hunts of the year. The weather here has been mild and I almost went fishing instead. But the fossil gods were calling to me and I couldn't resist their siren song. I decided to visit a site that I haven't been to for awhile. I am sorry but a have made a New Years resolution to no longer name locations for the world to see. This is a site that I have gone a few times with minimal results. Mainly it is a rather large site and the rock is hard to work. But I knew the potential for nice finds were there. So, Yesterday I arrived in the afternoon, planning on putting in a few hours. I started off on a lower layer. Now there is multiple layers of shale mixed with slate and limestone. The way this material fractures is rather strange. Which makes recovery of specimens rather tough. So while I found many cool things most where damaged in some way. Crinoids, brachiopods, bivalves, gastropods, nautiloids and trilo Cephalons were fairly common. Some were even pyritized. I must have been there for a couple hours before I decided to explore farther up the slope. I noticed a different color rock closer to the top, but there was really no where to stand. I grabbed a couple loose pieces and started seeing parts of corals and crinoids that were larger then any I have found before. Also partial trilo bits and pieces of Eldregoeps. I looked for a way to get to the very top of the slope and found a way that was not at first obvious. And then bingo! I found a small section that was easier to work and I immediately was rewarded. I started finding abundant amounts of horn coral, large crinoid segments and a nice slab with a horn coral with a trilo right next to it and possibly more. Then I removed a chunk of rock and uncovered a huge tabulate coral about the size of a dinner plate. Unfortunately this specimen was fragile and was broke into a million pieces. But I recovered some of the larger pieces. It started getting dark so I left for home with plants to go back this morning, which I did. Today was much of the same tons of corals but one horn coral was about the size of a grapefruit. This is definitely a different species than I am used to seeing. Most if not all need to be cleaned up and possibly prepped. So I plan on trying to clean up and get the mud off. I will post pics later this evening. It looks like this year has started off with a bang. I hope it is a sign of things to come.
  7. Here are some of the cephalopod fossils from my latest fossil hunting trip. Enjoy!
  8. I found a new place to fossil hunt and it has many more fossils then the normal places I go. Lots and lots of coral, brachiopods, cephalopods, and crystallization. It honestly looks like a coral reef of some kind. I live in middle Tennessee and it's mostly Mississippian and ordovician in my area but there are some areas of Silurian-Devonian. I found this fossil first and thought it was some sort of larger cephalopod, but there were some strange things about it and I started to change my mind. It is a torpedo shaped fossil with crystallization. I will start with the pattern pictures first to show you what I mean and then I will post a picture of the whole thing with a size reference. There are spots distributed around it but they seem to be symmetrical on both "sides," some are clearer than others. There are scalloped edges on the "bottom" of it. There is also an upside down shaped V at the "front-bottom" of it that I think looks kind of like a fish jaw. I do realize that if this is a fish it is very rare for this time period, especially in this sort of shape. If you do believe it is a deteriorated cephalopod, if you could just explain the V shape and the spots, that would help me see it as well. Thanks
  9. Last autom I found two nautiloids in Hadeland, Oslo-field, in another a little older formation than the other nautiloids I have found in the area, but also Katian, Upper Ordovicium; Kjørven formation (a. 447-448 my). I waited until now to present it, because I used some time to identify the right formation. The first one I thought first that it is an orthocerid nautiloid, but it seems (if I am right) to be a discosorid, because it has bullettes and possibly thick connecting rings and relativ broad or oval shaped siphuncle near the ventral margin of the conch. Its shape, although a mature part seems missing (and the apex is not well preserved), is slightly endogastric curved (seen clearly by the overall shape of the sequence of the connecting rings). I have marked where is the apex with arrows in pict. 3. The aperture with the living chamber should be in the opposite direction, because the bullettes are "hanging" down in the direction of the apex (the juvenile part of the conch). Pic. 1 Pic. 2: Pic. 3: Pic.4 - the other side of the rock, shows that is is almost flat, similar to an actinocerid, on that side too, maybe because of erosion?: Pic. 5 - aclose up on the connecting rings: Pic. 6-7 - show the the siphuncle (see arrows): Pic. 8 - cross-section: It is not clear everywhere that the connecting rings here are thick, but in some parts it is so, as shown in the next picture 9. It often happens with discosorids that only the outer layer of the connecting ring are preserved. According to Flower and Teichert “a striking peculiarity” for discosorids is “the unusual thickness of the connecting rings”, composed of a spherulitic–prismatic outer layer and an inner and thinner organic fibrous layer. I wonder if these two layers are seen in my speciemen? In the below picture I mark the two layers indicated by arrows by "I" for the inner layer (which often is not preserved) and "O" for the outer layer. Pic. 9 - close up of layered connecting rings:

    Weird Fossil ( Missouri )

    Location is in Missouri The area is dated to the Pennsylvanian Formation: Probably apart of the Raytown limestone member Found this weird fossil on my latest fossil hunting trip, I personally believe it to be some sort of Amminoid since the pattern seems to extend away from the shell and not towards it, but I have only found Nautiloids in the area ( Only 2 spiral shaped specimens that do not look like this and 3 cone shaped.) If anyone can Identify if this is a an Ammonoid or something else I would love to know more! the middle Section with the weird ball like pattern in the middle and what I assume are gas chambers around it
  11. This weekend I visited again a late ordovicium site north of Oslo, as I now know is the katian period (that applies to the earlier posts on this website which I then, mistakenly, thought was middle ordovicium). First, for the first time I found two graptolites in a limestone, and first time in this site, I m not sure but I think it is graptolites, but it seems so. Next, I found this stone which, I believe, includes an Gompoceras Nautiloid (the brown in the middle) and some nice gastropods. The size of the Nautiloid is about 4,5 cm. And then this small gastropod presered in tre dimensions
  12. There are so many tens of thousands of fossils at the lakefront park that I never get bored, and sometimes one finds something new. Today we saw the first trilobite portion ever in this rock. There were also some colony creatures I didn't expect. 'Ordinary' finds were beautiful lamp shells, Pterotheca expansa, gastropods, and cephalopods including Beloitoceras.

    Sandstone Nautilus Steinkern?

    I found this intriguing rock in Northwest Arkansas, in the Bloyd Formation I believe (carboniferous). It really looks like a steinkern to me, but I've only found limestone steinkerns before, hence my doubts. It's approx. 3" x 2"
  14. Oye I managed to get my hands on some very rare stuff (at least in terms of my local area) while hunting this last month in the Georgian Bay Formation in Toronto, Canada. Some of these fossils have been some of the nicest I've ever found, and will probably look even better with a little cleaning. Let's start things off with the usual nautiloids with a side of bivalves: Treptoceras crebriseptum I love these plates so much - they are currently some of my favourite fossils in my whole collection at the moment Treptoceras crebriseptum for the first three, the one on the far right might be a different species as it has a unique spiralling pattern.... Some MASSIVE nautiloid chambers, the biggest I've ever seen!!! A bunch of Rafinesquina brachiopods (I think). These are usually somewhat rare but I've found a lot recently so that is pretty cool A couple Ambonychia and what I believe are Pholadomorpha pholadiformis. A close up one the Pholadomorpha pholadiformis in the middle - one of the most exceptionally well preserved specimen I have ever seen!!!!
  15. Heres' are some Kaibab Formation nautiloids I found this weekend.

    Another classic trip

    Another decent haul over the last few days. Bunch of nautiloids and whatnot, a couple mussels. These were my favourites from the last 2 days in the river. This was a biiiiig nautiloid, and after cleaning it I realized there were two of them! wowowowo! (Sorry the picture didn't turn out quite that nice) This is probably one of my highest quality specimen so far, although it did break near the end when extracting it from the matrix.
  17. Wowowow I was very surprised to find all this amazing stuff today at my favourite river bank fossils spot of the Etobicoke creek. I managed to snag a whole lot of stuff today, some Orthoconic Nautiloids, Brachipods and what I believe to be the nicest tentaculite I've ever seen!!! The fossils are from the Georgian Bay Formation and they were found in the broken up "rock fields" next to the creek. This is going to be one of my longer posts, so I will have to split them up into section. The full haul, with the typical estwing 22 ounce rock pick (33 cm from bottom of the handle to the top of the hammer end for anyone who doesn't own one). First lets start with the usual: Them cone boys, aka Orthoconic Nautiloids. I believe all of the following to be Treptoceras crebriseptum.
  18. In my ongoing hunt to find as many different cephalopods as I can here are some nautiloids! All found in Central Texas, the most recent one just last week in the Dessau Formation in Austin Chalk. I thought it was an echinocorys echinoid (which is what I was actually looking for....goes to show that you should look for something other than what you actually want to find.... or just be happily surprised with what you DO find). The little round part was sticking out of the wall and I was so excited! Popped it out with my screwdriver and lo and behold, there was more to it in the wall...I could see the suture section where it had separated. Had to go back a few days later (with the rock hammer, and fortunately for me, the rock hammer wielding husband who managed to extract if for me as I was not having much luck). So here is Eutrephoceras campbelli. I'm actually glad it popped in half because you can see just a little bit of geodizing in the black and white area. Wouldn't have seen that if it hadn't come apart! Next is a chunk of Paracymatoceras - it's hard to get good pics of this one...it's just a chunk. And then my little Cymatoceras that I found in the Blanco River: And the best one of all, which I did not find but was gifted to me (Thank you John!!) is this lovely Cymatoceras:

    Cephalopod section?

    Need help with identification. I have a pretty strong idea that this is a weathered section of a cephalopod but I would like to be certain. Your feedback (as always) is appreciated. :)-
  20. Hi all! I managed to go on 3 large fossil hunting trips this weekend and pulled in easily the BIGGEST haul so far with the most variety as well! The first two pictures were from Mimico creek and the rest were a mix of Humber river and a separate section of Mimico creek. I managed to pull in my second trilobite from the area so that was very exciting! Also pulled a bunch of stuff that I was not able to identify: /\ This was the haul from last Friday night /\ This is the trilobite I found!!! Very excited to have a second one - its been a while since the last one I found /\ This was the full haul for the weekend trip at Mimico and Humber /\ Some Orthoconic Nautiloids as usual. Although it seems that this isn't just the same species I usually find as some of the patterns were much smoother than what I usually find A couple decent looking Crinoid stalks /\ /\ Lots of different shells this time, with a nice range of lined shells as well as 'mussel' looking shells (don't know the scientific names for these ones yet - sorry :/) /\ A close-up of the real nicely defined deathbed of TONS of shells! Unfortunately the hammer I used for cracking bounced off this rock and mashed my thumb in so that wasn't very fun. But its healing up nicely so I'd say it was worth it haha /\ Variety different sizes of coral (if you guys could help me identify which type that would be sweet!) /\ These were the weird ones. I'm not even sure if these are even fossils but I figured I might as well take em just in case - better safe than sorry!! (I am posting these two in identification later!) I was very proud of this haul! Lots of diversity compared to the usual hunt which is nice because I'm kind of getting a little tired of the mountains of Nautiloids we have piling up in the collection Let me know what you guys think of these ones!!! -Em
  21. Location: Etobicoke creek, Toronto, CA Date collected: July 27th, 2019 Hello! I pulled in a whole bunch of fossils along the Etobicoke creek (a little bit further north compared to my last trip - almost same location though). LOTS of Orthoconic Nautiloids (as usual), a couple different bivalves and a few crinoid fragments. This is the nautiloid haul. The top right one doesn't look like much but there are about 5 or 6 nautiloids embedded in the matrix! I'm considering learning how to clean up the fossils so that I can show it off in all its glory! These are the bivalves and other stuff collected. These are two separate MASSIVE chunks of monster Nautiloids (~5cm in diameter) - hopefully I can clean this one up as it would make a veryyy nice shelf piece! Closeup on the full bivalve, I've never really found a complete bivalve with both shells in one clump like this before (correct me if its actually just a lame rock - I could be wrong). I thought this one was really interesting: notice the dark brown, lined layer just under the rocky outer layer? I've seen a good lot of Orthoconic Nautiloids but I haven't seen a layer like this before. Maybe its nothing but I thought it might be worth looking into - let me know if you guys have any info, or what you think! Anyways thats what I pulled in this past weekend! I'd say its a decent haul, not my nicest stuff but still a good lot. -Em
  22. I just spend the evening cleaning and preping some of the cephalopods I found last weekend. those are all from the cenomanian at the French coast. A couple of nautiloids ( Eutrephoceras sp. ) A couple of turrelites and a Manteliceras sp.
