  1. Crinoidal Holdfast?

    Here is a picture of what I believe to be a crinoidal holfast on a brachiopod shell. This is very small (scale on the side are mm's) but I thought it was pretty neat looking. I found this while cleaning some of my material I collected earlier this year from the Haragan Formation (Lower Devonian) near Clarita, Oklahoma. When I first saw it, I thought: "this looks like a little starfish", then I learned to count! So I am assuming this a a holdfast, but I am wondering if anyone can : 1) confirm that; 2) provide any more precise ID; 3) point me to any references that might help. I have gone through Oklahoma Geological Survey Circular 55 on crinoids, but did not see anything like it (it doesn't have much on holdfasts, no surprise). Thanks for any help anyone can offer.
  2. Givetian fossils from Poland

    Hello, I have found these during my recent trip to Wymysłów and Śniadka, two locations in Poland with middle Devonian fossils of the Świętomarz Beds. The ones from Wymysłów seem to be some kind of trace fossils:
  3. This saturday Natalie and I went on a fossil hunting trip to my favorite huntingspot in the hope to find a few devonian cephalopods. The weather conditions were cold but sunny to cloudy and the rain of the last week removed the dust from the rocks (although making the place muddy ) Not a lot had changed since our last visit, no expansion in the quarry or new scree piles so it didn't look verry prommising. But with a little perseverence we did get our haul of goniatites and orthocones. most came from the upper parts of the quarry so the were a bit wethered, although Natalie found a few very nice specimen. My best find was a rare nautiloid, but I have to prepp it out to see how it will turn out. after the hunting trip we visited an old marble quarry hidden in the forests in the area: Enjoy the pictures some vieuws of the area when leaving the quarry: some of the finds of the trip:
  4. Favosites sp. from the Devonian Hungry Hollow member in Arkona, Canada. One of the more interesting corals I've collected, I'm trying to narrow down the species if possible. Any ideas?
  5. Hi guys! Haven't made any posts in a while but as I was going through some finds from Penn Dixie recently I have come across a few more fossils I would like to ID. The first few are what I believe to be Pelycopods but I have no further info on them. 1. Part and Counterpart 2. Part and Counterpart, found in the same piece of shale very close to number 1 3. Smaller one among some horn corals 4. A larger one, this one is thicker than the rest and is very different in texture. I have a few more pictures but I don't have space so I will include them below, Thank you guys for any help, Misha.
  6. I had a rough work week last week with Central New York experiencing major flooding. It forced me to work the weekend and kinda ruined my fossil hunting thoughts. I only worked half a day Saturday 11/02/19 so I took advantage of what little sunlight I had. I had to be home before 5 to go to the mall with my wife to return some soccer shoes.......married life lol. With travel time I figured out I could go to DSR and get 70-80 minutes to fossil hunt! I needed this to de-stress so I went for it . I didn’t get much time but I tried to make it count. I knew I wasn’t going to be doing any major digging due to the lack of time. My plan was to try and keep working slabs I pulled from the interval I keep finding phyllocarids. When I got there I saw a large area to the left of where I worked that was ripped up with slabs around. It was the same interval and layers as the productive ones I worked 30 feet away. I wish I recorded the moment because I literally said out loud “I’m going to find a phyllocarid in these discards”.......walked 2 steps and found this in the discard pile.... here is a field shot....I was excited and terrified cause I realized I just found a Rhinocaris columbina phyllocarid with both carapaces and the telson but the telson is on the counterpart!! I thought I was going to have another fish that got away story but then I finally found the other half after an agonizing 40 minutes. Remember I didn’t have long haha. here is a field shot of the other half. Telson top left. I got a call from work and I was literally on the phone working and fossil hunting when I found the other half and silently cheered then continued my phone conversation here is a photo of the raw uncut slabs I collected from the field. I have a saw now so I’m not as concerned with reducing in the field as I used to be. Here are some photos of the finished product. This is a really exciting find because of the amazing association of both carapaces AND the telson. Really an informative specimen. It also came from the same interval I’m finding other phyllocarids. The very delicate disarticulation of the one carapace and slight spread of all the phyllocarid parts makes me very curious about the paleo setting. This is a photo of an artists recreation of a Silurian phyllocarid I found on google. This is not a Rhinocaris columbina but it does have some similarities that will help people visualize what a Rhinocaris may look like. this little something I circled had me wondering if it was possibly associated with this phyllocarid. Almost seems like a little appendage but there is really no way of knowing for sure I suppose. Interesting either way. thanks for reading! Not a whole lot just a single find that I think is really awesome . A quick little DSR trip (11/02/19) with a nice reward! Al
  7. 7 items in need of ID

    These are eight finds that have me scratching my head. Please help me identifying them. Some are so very worn, please feel free to just guess. #1: "Oddball". Feels glassy, hard. Inside, I can't see much further by eye than what's visible in the photo. Just more of the hardened lentil soup..... #2: "Mystery Shape" While it looks grainy, it actually feels really smooth and hard. It reminds me of a mollusk shell cut at a slant? Or an extremely wide spaced chain coral? I love its elegant shape. Oh, and it's about 2cm long. #3: "Bandaged Dude" Is it possibly a bryozoan "sheet" that's draped over something else? #4: "Spiral Stairs to Nowhere" I split a piece of limestone and several of these became visible, each in its own empty casket. Doesn't look like a crinoid stem. (Sorry about the out-of-focus, bad quality photo, alas, it was taken in fading light without a tripod) #5: "Zigzag Doodle" I promise, it wasn't me who defaced this rock... #6: "Gas Bubble" This thing has very thin but hard and very sharp edges. It's about 1cm deep, yet, it weighs all of 5 grams. I have the beginning of a paper wasp's nest of about the same size, which weighs about 1 gram. So it's barely heavier. Also, what might the small egg-shaped things be which are visible in the bubbles? Worms? #7: "Metallic Paper Fringe" The slight metallic sheen isn't visible on the photo. Anyhoo, I can't even guess....
  8. Fossilized Thumbtack

    Here is a piece I saved on a recent excursion to the Devonian Cedar Valley Formation of Iowa. It looks like a thumbtack!!! I am guessing a tentaculites abutting an ostrocod, but would like other opinions. Thanks, Mike

  10. prepped moroccan nautiloid?

    hi guys, every one knows and recognises probably the most commonly sold fossil in the world, the "orthoceras" though not actually this species, they are always ground down and i was wondering whether anyone had some actually properly prepared pieces that show enough details to be identified?
  11. Iowa trip

    Just thought I'd share some finds from a club trip to the Devonian of Iowa last Sunday. It was a good trip. A nice clam. This Greenops disintegrated shortly after exposure. Crassiproetus sp. Before After. Enrolled Greenops sp. and Eldredgeops noorwoodensis Group shot
  12. still learning

    Sorry I haven't been on the forum in a while since I've been working like crazy. After a 71 hour week last week I took a day off. My new job is a driving job around my local area so I make notes of places to revisit to rockhound ( I also do some while on layover time but its hard not to get dirty!). I went back to one today, It is a Bralier Shale (Devonian) exposure. Here's where I need some help. Are the tube things #3 corals or bryozoans? Any id's on the other things would be appreciated. Scale on all is centimeter.

  22. Devonian Coral - B.C. Rockies

    I picked up a few pieces of this stuff at a Devonian site in the Bull River Valley this past August. The tour guides weren't much help, and it's hard to find info about corals if you don't know the terminology very well and maybe there isn't much literature on corals from this site? If I could get the possibilities narrowed down, that would be better than nothing. I just figured it looked distinctive enough that someone might recognize it. Very small corallites, 1mm scale or less. All I know about the site is that it is supposed to be Devonian. Forgot scale on this first piece but the following ones have it. There is at least one other type (maybe two) on this piece as well, toward the right.
  23. Devonian? New Jersey Fossil ID help

    Hello! I found this tiny fossil in Mercer County, New Jersey but I think its a glacier transport from New York. I noticed it had an intricate pattern so I was wondering if anyone knows what it is. Thanks! Frank
  24. Hi all, It's been a while since I posted a trip report but I was feeling like posting last evening as well as testing out my new photography rig. I moved houses two years ago and lost my lovely brick wall backdrop (the exterior of back of the house) which allowed photography in natural light. The new house is all vinyl siding outside and I have more shade so less opportunity for good sunlit pictures. However, one corner inside the house has a bricked area where a wood burning stove used to be so I have decided to set up some lights there. The pics came out ok so let's proceed with the report. I recently went up to the St. Mary's quarry in Bowmanville, Ontario on a scheduled trip with the local Scarborough club and also stopped off at Arkona while in Canada. I did pretty well at Arkona where I found four Eldredgeops trilobites and two Blastoids among other finds. Nucelocrinus elegans from the Hungry Hollow member of the Widder formation. Sorry, no pics of the Trilobites due to some back spasms but I got these pics of a nice Atactotoechus fruiticosus branch also from the Hungry Hollow Member of the Widder formation. Then I went to the St. Mary's quarry on Sunday where I took a tumble down the rock pile and hurt my ribs. Lucky for me my hard hat took the brunt of the impact my head made with the rocks. With nothing broken and still able to move around, I stayed closer to the ground and found this partial, eroded Isoltelus sp. that is inverted and still shows the Hypostome in place. I also found a plate with Graptolites but that was too heavy to hold and photograph last night. I'll post it tomorrow maybe. Finally, I drove home on Monday and stopped off at a place in New York where some of the Kashong Shale member of the Moscow formation is exposed and found these two surprises. A cephalon of a Dipleura dekayi with some of the shell material eroded away. I think the eye is intact and waiting to see again once some rock is removed. And here is a closeup of the shell on top where you can see the stippled pattern where sensory pits used to be. Lastly I found a pygidium that I am not sure of the genera on. Possibly a Basidechenella sp.? So not a bad trip at all, despite the injury. Good news is that I am healing nicely but still have some soreness and muscle spasms. I'm looking forward to my next trip up in the spring and hopefully will avoid the health scares.
