  1. 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
  2. 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"
  3. Here are some of the cephalopod fossils from my latest fossil hunting trip. Enjoy!
  4. 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.
  5. 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
  6. 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!!!!
  7. Heres' are some Kaibab Formation nautiloids I found this weekend.
  8. 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.
  9. 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.
  10. 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:
  11. 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. :)-
  12. 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
  13. Toronto creek - big haul

    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
  14. 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.
  15. So I went back to Tannery Park to find fragments...got a few gastropods. But walking on the rocks, I encountered lots that I had missed. Brought my wife along and her eyes are sharp. She found a couple of nautiloids so large that I can't believe I missed them before. I'd not noticed many brachiopods before, but I did this time. Also lots of "periwinkle beds". This place will open to the public as a lakeside promenade in September.
  16. On the west side of the harbour in Oakville, Ontario, they have set up a waterfront with hundreds of big stones from Orillia. They are covered with fossils...many thousands of them, and some quite striking. Last I saw, it wasn't officially open, but it's accessible.
  17. sorry again, i dont know what the species of these specimens are and also sorry for some reason parts of the photos were cropped and made smaller i think its because i put too much on there so they had to cut down the file size (:
  18. The included photograph shows a fossil that we can’t quite place. Would any of you be able to positively identify the fossil we found at Portmarnock Beach, Ireland. We think it may be Estonioceras but are not sure. It is approximately 7cm in diameter. Can anybody shed some light on this. Thanks.

  22. Toronto creek and river finds

    Hello there! I'm still in the process of deciding which fossils to put in my new display cabinets, so I'm looking for some identification help, if possible. All of the items pictured were found in the Toronto area (Georgian Bay Formation, Upper Ordovician) along creeks or rivers - please help me identify them if you can! Thanks in advance! Monica Picture #1: A trace fossil, but of what? Someone suggested trilobite tracks, but I don't know - what do you think? Perhaps @piranha can have a look... Picture #2: This may or may not be a trace fossil - I only just noticed it today. It vaguely resembles trilobite tracks to me (cruziana), but I'm definitely not sure...

  24. I have had the urge to go find more echinoids for a while. I’m still not finding the variety I’d like to have. I have lived in North Texas many years, but recently moved to a new area. So I don’t know where the good sites are yet. I got out the satellite map and searched for a good creek with a good span of dry spot near a bridge and headed out to check it out. I’d never been to Oliver Creek, but I have heard a lot about it. So I headed out to part of Oliver Creek near Roanoke, TX. I have the phone app “RockD”, which told me I was in the Paw Paw. I just got it last week and haven’t had much time to play with it, but if it could tell me the right formation that’s great. It definitely saved time trying to figure it out. It was helpful, because the USGS map told me I was in the Plestiocene Alluvium Formation, which I knew wasn’t right by the looks of the creek bed. It was in the 50s, but bright and sunny with no breeze. I could have parked on the shoulder near the bridge and gone down into the creek, but it was a very busy road and I saw a field a short ways back with 3 trucks parked by a gate. I drove back to the spot which appeared to be a popular spot for hikers and hunters. However the hike to the creek seemed close to a mile. Not a problem walking there, but walking back carrying what must have easily been 40 lbs was a different story. These are pictures of the creek and formation. The just limestone shelf on the left is where I found all 3.25 echinoids that I did find. Along the banks was this densely compacted sedimentary layer with pebbles, small rocks and the occasional sea shell. The riverbed didn’t have hardly any fossils in it as I expected it to have. The scarcity of them seems a bit odd to me. I’m use to seeing a lot more river worn oysters and such at the very least. Before turning around to go back to the creek I attempted to find an entry down a dirt road. I ended up at a trailhead with a dry creek by the parking area. I thought I’d check it out while I was there. I found a bunch of Waconella wacoensis brachiopods and Llymotogyra oysters there and iron concretion fragments, but not much else. That creekbed was maybe 1.5 miles away at most, but I didn’t find a single instance of those shells in Oliver Creek. The most prominent fossils I found in Oliver Creek were burrow fragments and what I believe maybe Inoceramus? clam shell fragments, fossils most people wouldn’t either want or know what they were. Here are some pictures of the burrows that were on the tops of small boulders shortly after I entered the creek. I believe these are thalassinoide burrows. You can see my foot in the bottom right of the pic for some gauge of size. I’m 5’10” so my feet aren’t tiny. Some of the burrows were easily 3 inches in diameter. I tend to think they were made by some crustacean like a lobster or crab. You can see a couple of the openings to tunnel on the bottom of the pic. Another boulder with burrows right next to the other. Much of the creek bed was gray or tan limestone. The tan sat atop the gray. Then the rock and pebble sediment sat on top of the tan. The lowest layer of sediment is where I found the echinoids. The gray and tan layers of limestone are where the nautiloids where. Many fossil hunters had been there before me. The limestone appeared recently hammered on in many places. Also the sedimentary layer above the tan limestone had been hammered away at. Strangely enough I found multiple nautiloids with just the center broken out and the bulk of the nautilus being left behind. I’m not sure why someone would want only part of it. It isn’t like they were washed away. I could see where the whole thing had been chinked out of the limestone, the center taken out and the bulk discarded. I consider myself to be a bit of a naturalist. I prefer to make very minimal impact if any on ecosystems and the environment or do anything to advance erosion or the breakdown of layers. So I tend to not like to hammer things away too much, but if I find a real beauty I’ll probably give in and extract it. My preference for me individually is to only take what is readily available. I do believe it can be acceptable in the name of scientific research and education, but I’m not a fan of it for capitalistic, opportunistic or personal gain. The earth and our environment need all the preservation and tender care they can get. It comes from my training as a biologist. I found 4 nautiloids. I think all are partial. I did take 2 of the scavenged ones where the outer whorls were left behind. I also found 3 echinoids and a top of one of a different genus. I don’t know what genus they are yet because I haven’t gotten them cleaned up. I found 2-3 oysters. Two of which looked a bit like Texigraphaea. That is the slimmest pickings for oysters ever for me. Normally they are the most abundant and are everywhere you turn. It makes me wonder if there is a dam upstream or some pit or other place they get hung up in. I found 2 other brachiopods, but they could be bivalves. I also found the nicest denture clam I’ve ever found. I’m not really a clam or brachiopod person though. Here are 2 of the nautili that I found. They were not in good condition. They split as I was removing them. This is a 3rd one I picked up. Someone had extracted it and left it sitting on the bank. There should be part of a whorl covering all the sutures or growth lines in the lower half, but it is completely missing. I think it was the part with the aperture, because I don’t see an aperture on it. This one is in the best condition of the 4 I found. I only had a tictac for size comparison when I took the pic. They were all Paracymatoceras genus. @BobWill said if it was Duck Creek and possibly Grayson formations that it would be a texanum species, but I was in the Paw Paw. So I’m not sure it is a texanum. These are cool fossiliferous rocks that I found. I’m not sure what the wavy lines are. Looks more like the front edge of a sea shell than a spiraled shell. This one looks like swirled caramel with nice colors and contrast. This is the best echinoid I found and it isn’t even whole. It is maybe 2.5 cm long at most. Center of pic. This is an echinoid top that broke away from the rest of the Test. If I had a dime for every time this happened I’d be rich. This is the first time I found the top without the body. Usually I find the body without the top or bottom. Here is an oyster with the denture clam. It appears largely while and well preserved. I found dozens of these brown layered fragments with 2 holes equidistant apart. The first plate I picked up was about 11 inches square, very thinly layered and felt like a very fine sandstone. So I put it down and moved on. Then I began seeing these everywhere. The majority with 2 holes equidistant apart. I figured it has to be biogenic and therefore a fossil remains of some sort. There are fossil traces on both of them. Several had snail boring marks. The only thing I can think of is Inoceramus clam shell fragment. Any other suggestions or input will be gladly accepted. I’m quite curious. I have pictures of more if needed. The rest of the pics pics are just nature and scenery pics along the trail. I took time to enjoy it walking back, whereas on the way there I made a b line to the creek. This is something a bit unusual that I noticed. The moss and lichen start growing on the trunk only about 5-6 feet off the ground. The whole forest was that way. I can’t recall ever seeing that. I’m not sure if it is natural or the result of a maybe flooding of the area. If it had been a result of Fire I would expect the height to be variable and trees affected in patches, but height wasn’t variable and different areas had the same pattern. Ita just curious to me. A mistletoe plant. I cut a branch off with my knife and brought it home for Christmas decor. Probably should have cut the whole thing down now that I think about it. It’s a parasite plant and damages the tree like the strangler looking vine in the background. That tree doesn’t stand a chance. The sun was starting to go down and was just above the tree line as I walked back. The sunlight was hitting the top of this tree. I thought it was pretty against the blue sky. This is the trail to the creek.it might have been 3/4 mile walk, but it was a nice walk. On the return walk my bag was just too heavy. It had to weigh at least 40 lbs. With the car in sight about a 1/4 mile away I put one bag down and took the rest to the car and came back for the other. My bag is the black speck in the distance in the pic below. I think the last 2 times I went fossil hunting I managed to have men ask me if they could help me carry my fossils and insisted they do so. Maybe I was walking too slow or looked too pathetic carry 40 plus lbs of rocks and fossils. One was a first time fossil hunting buddy young enough to be my son and the other was hunting buddy wanna be. LOL I ran into him while he was fossil hunting too. I’d never met him before, but he gave me his number and asked me to call him if I wanted to go hunting with him. I get that quite a bit for some reason. People sure are just friendly in these parts especially so out in the woods. But yesterday there wasn’t a man in sight! They were all out hunting deer rather than fossils. While I was in the creek I kept having the feeling someone was watching me, but I never saw a soul until towards the end. I’m not the least bit paranoid so I don’t usually have that feeling. I think they must have been in deer blinds, because finally a guy walked out of the woods in full camo with hunting gear and kind of walked in a grumpy, frustrated manner further down the creek. I think I must have been ruining the mood for the hunters, but didn’t put 2 and 2 together until the moment I saw the hunter in camo. I forgot to mention that the creek was covered with deer, coon and coyote tracks, but mostly deer. There were also these little things all over the ground on the trail and in the creek. You’d think I’d get a clue and get gone, but I only had 30 min before I planned to leave and I was heading back by then anyway. I probably should have mosied a little faster though. Dusk, deer and shotgun shells. Not the best place to be at dusk, but I’m blond and it takes me a while to catch on sometimes. That and I’m in the fossil frame of mind.
  25. Hi All, Another chapter done on our study of the enigmatic Fort Apache Limestone! We found one orthocone, and juvenile coiled conchs in our search in 250 pounds of limestones. One larger specimen which we thought was a huge nautiloid turned out to be a big Straparollus gastropod when we finally made a clay cast of the mold in limestone. So without delay, here is this weeks write up! Lower Permian Nautiloids are found in both the Fort Apache Limestone, and overlying Kaibab formation. Far more commonly found in the Kaibab, they range in size from quarter sized to 12 inch monsters. But in the Fort Apache, we have found so far only two nautiloids in our years of searching. Fortunately, they are both different morphologically and offer an interesting cross section of cephalopod life in the Fort Apache Sea. It is notable that Winters, in his monumental GSA monograph memoir 89 found only the orthocone type and identified it tentatively as Psudorothoceras knoxense. Aperture comparison. The differences in similar mollusks can be ascertained by comparing the shapes of the openings. (Aperture) On the left, Bellerophon - a monoplacophoran has a decidedly triangular opening. Center are a gastropod called Knightites sp. which looks very much like a small Bellerophontid, but is a gastropod. And on the right, the cephalopods have a much larger and oval opening, such as the small pea sized specimen we found below. This little cutie was found mixed in with our first picks for gastropods out of the acid fines. This was the only one like this, and you can clearly see the septa evenly spaced along its periphery. The center is filled in with sediment thus appears as a mound here hiding the details of the inner whorls. View of the aperture, a bit crushed showing the inner whorls tucking into the opening oh-so-nautiloid style! Orthocone nautiloid section found at site 2 as well. This is an orthoceras type cf. Psudorothoceras knoxense. The septa can be seen inside the eroded openings in the outer conch. Fortunately, one end has a great view of one of the concave septa. This then would have been the side that the animal lived on in the conch. It is difficult to say how long the original conch was, perhaps 6 inches or so. We Well, thats it for this week. We were hoping for some really big nautiloids like we find in the overlying Kaibab formation - which is the same age. But no, that will have to wait till next year! Next weeks posting will be on the gorgeous Straparollus gastropods we found, ranging in size from pinhead to hefty 6 inchers.
