  1. Moroccan Atlas and Sahara.

    I am leaving tomorrow for a five day trip to explore some of the Moroccan Middle, High and Anti-Atlas Mountains and parts of the Sahara. Yaaaaaaaaaaaaaaaayyyyyyyyyyyyyyyyyyyyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If I seem a bit overexcited, it's because I am. This will be my first Moroccan collecting trip since the TB struck me in 2011/12. I won't be posting on a day by day basis, i don't think, as my laptop stays here and wifey's phone thing is beyond me. However, wifey's presence for the first time on one of my trips will enable me to take photos for the first time ever. I hope. A past student of mine who is a tour guide here is driving, along with his brother, because he gets asked geological questions a lot by the tourists and hasn't a clue. So in return for free accommodation and transport I have to teach a little basic Moroccan geology. I think I'll have to pay for the booze and fossils though. But I'm hoping to find more than I buy! So many, I hope, that I'll fill the 4x4 with them and wifey and the brother will have to walk home. Wish me luck, full trip details to follow when i am able.
  2. Although we are currently in the depths of February, spring is just around the corner! With spring comes spring break and a week of digging!! One of the locations I am planning a visit to is Jamesville quarry in Jamesville NY. I would love to unearth some nice placoderm pieces. If anybody has info about the site, especially who to contact for permission, I'd greatly appreciate it!
  3. Today we had a field trip with the "Lithos" geology club at my favorite hunting spot. Although the day started with freezing temperatures, the sun quickly rose the temperatures during t morning and gave us a beautiful day. the last time I visited the quarry the finds were disapointing due to the lack of activity in the quarry, but today we were lucky and the past week a new acces road was being dug to the side of the quarry, straight through the Matagne slate. It didnt take long before I found my first fossils, at first a few halve goniatites, but after a while a complete large specimen and a nautiloid that I had never seen before at this locaton. we searched further in the quarry where we found the spot where the rest of the slate was dumped, resulting in a couple extra goniatites, one of them was an exquisite specimen and a 2nd nautiloid. Note that al the goniatites this time weren't Manticoceras specimens, but an other Gephuroceratinae: Crickites sp. they differ from the former with a more bulbous shape and large size ( up to 30cm in diameter ) In the afternoon we prospected the usual scree piles at the back of the quarry where we found a multitude of small pyritised cephalopods and I even found a broken nodule with very rare placoderm remains. Natalie also found a large and complete Crickites sp. at this spot This day turned out to be one of my most productive days at this location.

  5. The Three Kings Stationary epifaunal suspension feeders Heliophyllum is an extinct genus of corals that existed predominantly in the Devonian. Heliophyllum is of the order Rugosa and can be referred to as horn corals. This is what the internet tells you about this well known and popular fossil coral and that's about it. I'm fortunate to have collecting sites here in NY with excellent examples of this very cool fossil. I thought it would be neat for you to see examples of three types of Heliophyllum that I find. Of course the most common species I find is Heliophyllum halli (Edwards and Haime 1851) the solitary rugose. This is The King of Heliophyllum corals and are common to find here in NY at certain localities. Complete or "fresh" specimens are uncommon. A fresh coral would be one that has just weathered from the formation and is undamaged, unworn/tumbled by a stream. The majority of the Heliophyllum halli corals I find are 1-3 inches long with many being between 3-6 inches and a few over 6 inches in length. I find some with perfectly preserved epibionts that help tell a story of that paleoenvironment Heliophyllum halli lived in. The next King of this story is Heliophyllum confluens (Hall 1876) the colonial rugose coral. This species is much rarer then the solitary Heliophyllum halli. Confluens can form large colonies made up of several individual coralites that form a solid coral head. Each colony is different and many fantastic shapes can be found in this species. The third King is Heliophyllum delicatum (Oliver and Sorauf, 1994) a budding colonial coral. Delicatum is only found in the lower Deep Run Shale Member of the Moscow formation. This is my favorite of the three kings. They are the rarest Heliophyllum to find and complete undamaged colonies are near impossible due to their delicate nature. Unlike Heliophyllum confluens, delicatum coralites do not grow together to form a coral head. Instead each coralite individually grows out of a single main corals calyx. This can happen several times within the same colony forming a bouquet of fossil corals. I am not an expert on corals past or present. These are my observations over years of fossil collecting in New York. I hope this helps in your fossil ID or clears up some confusion when talking about these Kings of horn corals. mikey
  6. Coral

    I've not been able to find a comparable coral to this guy. I'm pretty sure it's coral, anyway. Lol Any of you know what it is? Devonian, Sylvania, Ohio. Thanks!
  7. Pecten?

    Might I be on the right track with pecten for this guy? Or would it be another brachiopod? Devonian from Sylvania, Ohio. Any insights? Thanks!
  8. Couple of finds

    I think I may have found my first Devonian bryozoan. (From Sylvania, Ohio.) And I also am not sure if these are shell or plant impressions. The rock that I think has the bryozoan has many nifty whatnots to explore, but that pattern immediately caught my eye. I'm not sure if the fan shape on the second rock is plant or shell. And there's a small bit to the left of it that appears to be shell that I haven't started to ID yet. (Pics in second post) Thanks for any help.
  9. My Trilobite Drawings

    Taking a break from grading essays, I gave the pencil another go. This is a prone Greenops. The shading is not as crisp in gradation as it could have been, but I was only using an HB pencil. I did get the pustules and eye lenses on it, which gives it a bit of texture.
  10. In search of the elusive isotelus

    For the month of March I will be in Ohio working and am hoping someone can point me in the right direction to find some Ohio trilobites. Even partial large isotelus and flexis are fine. Maybe an Ohio crinoid as well. I hope someone can help and maybe even meet up and we can collect together!
  11. I am looking to trade some of the fossils I’ve collected at Beltzville State Park and Montour Preserve for fossil shark or crocodile teeth. I pictured the fossils I’m looking to trade. Bivalves, coral, and some rocks with multiple specimens. If someone is interested in anything and has something other than what I’m looking for don’t be shy throw an offer my way, I’m interested in just about everything and would love to help expand others collections. Thanks all If anybody needs any other pictures of anything let me know
  12. I was traipsing around in a wild geologic zone 'red ellipse'. Lots of faulting, etc. I was in the orange area when I found a block of what could pass for recently dried mud having quite a few tiny brachiopods about 5mm in width. Maybe the brachiopod lovers could help put a generic name to this one so I can do more research? There are some larger brachiopods of a similar appearance (yet different) on the specimen but the largest barely gets to 10mm. I will post additional pics tomorrow when I get better lighting.
  13. Tiny Unknown Devonian

    @Peat Burns, This one is for you. I am staking my reputation (which doesn't mean a lot) on you to be able to ID this Paulding, Ohio unknown. Your info on species of Paulding mounds has been very helpful to me so far. Collected in early January.

  15. Need help. No idea

    Found this on a field trip this fall. Looking for any suggestions on what it could be.
  16. Hi, I have a good selection of self-found Devonian aged marine fossils from Ontario, Canada that I am offereing to trade for shark teeth. I have; -several species of brachiopods -a few species of gastropods -ammonites -corals -Bryozoa -trilobites -and more All of my specimens are self-found and many are identified to genus or species. I can provide detailed location and age data with the specimens. Also, I have lots of photos available upon request, but here are a few to give you and idea. i am looking for shark teeth, especially; -interesting Cretaceous teeth -Carcharocles -Carcharodon and/or cospopolitodus -Cretoxyrhina, Cardabiodon, Dwardius -Palaeocarcharodon -Leptostyrax -Ctetodus -interesting locations -anything else interesting Thanks for looking!
  17. I've always wanted one of these and it's just arrived! I spotted it on the usual auction site where it was being sold by an antique seller as a possible fish in slate . It is true slate but is a legendary Delabole Butterfly, a metamorphosed Cyrtospirifer extensus, almost certainly from the Delabole slate quarry in Cornwall, UK. Although quite famous and widely referred to, there's not that much solid information. They appear to have been sold to tourists, largely in the 19th century and this split specimen seems typical. I think they're quite rare though - most photographed specimens seem to be in museums. Many years ago, I wandered around the edge of the quarry and managed to find one small fragment in the waste. Devonian, Frasnian, about 4" across. ,
  18. Bothriolepis canadensis Whiteaves 1880

    Bothriolepis ("pitted scale" or "trench scale") was the most successful genus of antiarch placoderms with over 100 species found on every continent, including Antarctica . The extinct armored fishes known as placoderms make up what is considered to be the earliest branch of the gnathostome family tree -- the earliest branch of the jawed fishes. Antiarchs are characterized by the fact that their pectoral fins are enclosed in bony tubes (pectoral appendages). Instead of typical fish-like pectoral fins, it bears a pair of rigid arms that are joined at two points. These arms, like the limbs of an arthropod, are articulated by interior muscles. Bothriolepis is a placoderm with a heavily armoured head fused with the thoracic shield. The body was encased in a bony box that had flat sides and bottom and an angled roof. There are two openings through its solidly armoured head -- a keyhole opening along the midline on the upper side for both eyes and nostrils and a mouth on the lower side near the front. The discovey of some undeformed, three-dimensionally preserved specimens led to a review of this fish's morphology. It appears that Bothriolepis had a much more rounded shape than previously thought, and as a direct consequence of the latest reconstructions, it is now believed that its eyes faced forward instead of upward. Bothriolepis does have a slender fish-like tail that extends behind the heavily armored portion but, because it is almost naked with few scales, it is rarely preserved. Placoderms bore heavy bony armor on the head and neck; in the past it has been suspected that there is an unusual joint in the dorsal armor between the head and neck regions; this joint apparently allowed the head to move upwards as the jaw dropped downwards, creating a larger gape. But one of the new discoveries shows there is no indication of mobility between the cephalic and thoracic armors. Bothriolepis had a peculiar spiral, sediment-filled gut and probably grubbed in the mud. It may also have used its pectoral fins to throw sediment (mud, sand or otherwise) over itself. Bothriolepis probably fed on invertebrates such as crustaceans and molluscs or even was a mud-grubber that ingested organic-rich mud for its food. Bothriolepis is the most common fish fossil in the shales and sandstones of the Escuminac Formation (Late Devonian, 380 Ma) on the south shore of the Gaspé Peninsula at Miguasha. Abraham Gesner (1797-1864), the provincial geologist of New Brunswick who discovered the site in 1842, referred to this fossil as "a small species of tortoise with foot-marks". It seems to be certain that there are at least two, with the second species discovered and described in 1924. Named B. traquairi (after the Scottish paleontologist Ramsey Heatly Traquair) the one and only specimen officially assigned to this species has a more slender body than B. canadensis. Because the fossils are found in freshwater sediments, Bothriolepis was originally presumed to have spent most of its life in freshwater rivers and lakes. This idea is now abandoned; many paleontologists now hypothesize that they lived most of their lives in saltwater, and returned to freshwater only to breed.

  19. Ductina vietnamica

    From the album Trilobites

  20. Hello to everyone, I was trying to put together a plan for a spring or summer trip hunting fossils. I am particularly interested in the animals of mahantango formation and would like to know if anyone is familiar with some public locations that allow people to hunt for the fossils from that formation, or at least do not prohibit this. If anyone can point me in the right direction that would be greatly appreciated, Thank you.
  21. Help with fossil from Oklahoma

    Hello looking for help identifying what is on this plate. The label says devonian oklahoma but then gets hard to read maybe ketternopsis willrameri. Thanks in advance.
  22. Devonian of Belgium

    Hello all I found these two fossils in 2014 during a trip in Vierves-sur-Viroin. These are Devonian in age and were found together with trilobites, brachiopods... First one is some piece of coral I guess, no idea what kind. About 3 mm in diameter. Second is a mystery. I have no idea if these are fish vertebrates (which would be rare since it is Devonian) or crinoid parts (never seen any that look like these from the Devonian of Belgium, but I might be wrong) or something entirely else? I see at least 6 of them in the matrix. It's 3D and I don't dare to prep it any further untill I know if it's rare or common. Thanks already.
  23. USA Brachiopoda ID

    Dear USA Brachiopoda enthusiasts, Could you see these images please? What is your expert idea about ID? I know that could be difficult from images. Thank you for any help you can offer. Ricardo
