  1. From the album Middle Devonian

    Greenops sp. (trilobite) Middle Devonian Moscow Formation Windom Shale Hamilton group Deep Springs Road Quarry Lebanon, N.Y.
  2. Eldredgeops rana prep

    Four hours so far into this big bug, and maybe another two to go. Found at Penn Dixie this past weekend, the visible area measures 6 cm. With the pygidium, it likely measured about 8+ cm. Judging by its size and pustular sculpture, this was likely a long-lived specimen prior to burial. This is how it looked fresh in the field:
  3. ID on Devonian Echinoderm

    I was on a quarry hunt with our fossil club yesterday and noticed this 1 cm. specimen in a sandy/ shaley rock that had scattered cinoidal fragments in it. No one could ID it, so I am offering it up to the experts here on the forum to tell me what it is before I attempt prepping it. The quarry is Devonian, but I can not tell you more than that since this was found in a heap of stones, not from the wall itself. thanks, Mike
  4. Yesterday I was in New Jersery for my son, Dylan's marching band competition. We had half the day free until they were playing at Rutgers stadium so we met up with @frankh8147 to hunt one of the Cretaceous streams. We met up around 9am and it was raining. Not a torrential downpour, but enough to soak into your clothes even with a raincoat. I wasn't deterred and neither was Frank. Heck it didn't seem to bother him at all. I would like to say Thanks to Frank for being a great host and guide to me and my family. He has such a great wealth of knowledge of the fossils from that area. Plus this was the second time since July that he was willing to meet up with us. It didn't take long to start finding fossils. Right off the bat frank found a cephalic clasper from a shark! It was a decent size and condition. I found mostly shark and fish teeth. Frank seemed to find more of an assortment including reptile. He gifted Devin a Goblin sharktooth, and myself a partial mosasaur. Sot of a highlight for me is what maybe my first point. I say maybe because frank wasn't 100% sure because it is quite worn but said he has seen similar pieces which after being looked into were in fact points. The key is to find out if the object is made of argonite. An old tribe used argonite for their points and does not occur naturally in N.J. Anyways we stayed about 4hrs before we had to part ways but it was a great time with a great guy. Thanks again Frank for everything, including the pieces you gave me before the hunt. Hope you like the New York trilos. ( Don't forget to get me the info of those pieces) Here are pics of the gifts and finds.

  8. Prepping nodules with Bactrites

    Although the most pieces of my collection are goniatites, I am more than happy to add other Devonian cephalopods to my collection from time to time. On my last field trip for devonian cephalopods I splitted a few nodules and some of them had a few uncommon fossils in them: Bactrites I rarely find decent fragments of them, but those few were looking promising. Bactrites, although they look like an orthocone are in fact straight Ammonoids and not a Nautiloid. the septas start to be slightly ondulated, but most important they have a ventral siphuncle, a typical trait of an Ammonoid. the first nodule had a fragment sticking out, and when I split the nodule another one was found inside. I kept both parts of the nodule and prepped the one inside and on top After prepping them I found out that neither of those were complete, but the were decent in size and well preserved. The second nodule on the other hand hand was much better, a piece of the Bactrites was sticking out from both ends of the nodule, so I new I had a complete specimen. The prepping was relatively hard as different parts of the cone had different forms of preservation, but in the end I got the whole specimen out of the matrix and is my best Bactrites until now. enjoythe pictures: 1st nodule with the specimen inside: after prepp: After prep with the top of the nodule containing an other fragment. prepp on the 2nd nodule: after prepp, with the different kinds of preservation visible: and the whole lot:
  9. Had another successful trip yesterday to Montour. It’s only my second time going but I really enjoy this place. Figured I’d share my finds with all of you! Partial stem? Clam that was still in the rock, this one actually was nice compared to what I normally find 4 small Pleurodictyum I found, top right is still pretty well encased A really nice shell, possibly oyster?
  10. Confirmation of Id

    Found this today, I used to call these coral but I think they're actually bryozoa. Am I correct? Sorry I forgot scale its about 1.5 by 2 inches.
  11. Dear friends, I need your help on identification of a fossil that I found in the Carpatho-Balkanides of Eastern Serbia. The fossil was found in a quarry of Upper Devonian turbiditic, fine to coarse grained siliciclastic sediments. Shales which bear the fossil are a top part of a complete Bouma sequence. This is maybe indication that the fossil was not transported by the turbiditic currents but was buried by sediment vertically from the water column. Late Devonian (Fameniann) age of the sediments is based on Cyclostigma remains which are wide spread in certain levels of turbidites throughout the quarry. It was a single piece broken in two. Basically the shape represents a concave and convex pair. Note the dark outline following the shape. I thought it was some ichnofossil. Outlines are often found on the surfaces of shales in the quarry. Thanks for your time and hello from Serbia!
  12. polishing some of my Goniatites

    I recently got a new job, and to make things even better, my job is at a company who processes and places floors and walls in stone, mostly marble. This opened a few opportunities for me , having access to a huge amount of polishing and cutting tools, so this week I gave it a try: I took 2 of my Goniatites that weren't of top quality, or to hard to prep. and today the helped me to cut the fossils and polish them. The fossils turned out really well here are my first 2 polished Manticoceras sp. from the Frasnian layers of Lompret in Belgium: before polishing them: after cutting and polishing: top goniatite: Bottom Goniatite: both of them: And a question for the moderators: the fossils have been cut and polished today, but were found earlier this year, are they valid entries for FOTM since al the cleaning , cutting and polishing was done now? Thx Kevin
  13. The Middle Devonian fossils of New York State are well known and have been for over 100 years. I grew up in Livingston County in whats called the Genesee River Valley. The streams that feed this river within the county are rich in Devonian fossils. I collect fossil corals, brachiopods, bryozoans, crinoids&blastoids, pelecypods, gastropods, cephalopods, phyllocarids, trilobites, fish, and wood. I rearranged my favorites in my collection and thought I would share since I feel the display will remain like this for some time. Out of the thousands of Middle Devonian fossils I have collected in 30+ years, these are the ones that mean the most to me. Thanks, Mikeymig
  14. Fossil Coating

    This is a gastropod from the Old Port Frm (ridgely sandstone). I know the fossil is a chert cast coated with Beekite rings. Any ideas as to what the black "crinkled/wavy/ridged" coating between the Beekite & the chert might be? The pattern is different from the rings above it. It is shiny black in sunlight. Fun fact: this came from a public park inside my city limits and was perched on a little pillar of dirt after the rain from the weekend!
  15. Second guessing a concretion

    Had a pretty good day out at my Thedford area spot today with some nice finds. I usually can pick out - and pitch aside - the infrequent concretions in the Widder Formation, but this one gave me pause. Perhaps I was out in the heat far too long, but this looks like it could be more than just a concretion, but unsure of what (giant ammonoid?). There's some faint ribbing, and a thin pyritized crust. I kept the impression pieces in case. Details: Mid-Devonian, Widder Fm (Thedford/Arkona, Ontario). Object at widest is 11 cm (or about 5"). Any assistance would be very welcome. If it is just a concretion, I'll practice some shot-put.
  16. Fibonacci Fossil

    I found this near Alpena, Michigan in the lake. In this area, I find Petoskey stones, favorites, occasional chain coral, occasional horn corals, and large, branching fossils in a black matrix. There are Devonian era fossils in this area. Obviously, I am not a fossil expert, I was mostly looking for Petoskey stones and pudding stones for lapidary purposes. I hunt this beach quite often, but have never found a fossil like this. It has a Fibonacci pattern like pine cones or sunflowers have.
  17. Hiking Out Back

    As the missus is at work, I couldn't secure a ride to kickboxing training, and I don't have any assignments to grade (yet), why waste a perfectly lovely morning? So out I hiked to the area just beyond my backyard to poke around in the spoil hills. As I've pretty much picked the place clean, my expectations were low enough that I didn't think I'd come away with anything - which was fine as I would be surrounded by the sights, sounds, and smells of nature. The spoils were laid down over a dozen years ago, and nothing all that new gets exposed over time; rather, sand and sticky mud that bakes hard covers more rock, or weeds and saplings extend their territory. I didn't come away with anything spectacular. Apart from a fragment of a very rare trilobite in these parts, this year has been a bit of a bust at this site. Mixed with construction debris are plenty of lower and middle Devonian limestones and sandstones, many of those that have no reliable bedding planes, or are just filled with tiny brachiopods, some bryozoa, bivalves, etc. There are virtually no trilobites left, apart from tiny fragments here and there. But I did find some ok stuff to take back with me. First up would be these relatively large brachs. I don't usually encounter big brachs in Devonian rocks:
  18. Gastropod or Cephalopod?

    Found this (Needmore Formation) at Lost River Site near Wardensville, WV. Size is 40mm, 1.5 inches. Anyone know what this might be? Thank you.
  19. Devonian Unknown

    A few weeks ago, I visited a quarry in central Iowa more for the purpose of its well known and beautiful crystals, not it's fossils: I was told that most of the "vugs" were a result of fossil reabsorbtion and calcite deposition in the void. It was hard for me to comprehend until I started splitting open the few brachiopods that I found. They indeed were crystalized in the middle!! Here is one I split open: Here is the purpose of my post. The dark item is not anything I recognize. Most of the time "black" turns up in this area, I am told it is fish pieces. Does anyone have a suggestion of what part of a fish this would be, IF it is fish at all??
  20. A Pleurodictyum Coral Day

    Today was a Pleurodictyum coral day The largest specimen is 116mm x 96mm, the biggest I have ever found!! Finding one of these extra large Pleurodictyums in a day makes the trip. The pictures of the large Pleurodictyum with the smaller size Pleurodictyum displays the huge size difference between a normal sized Pleurodictyum (35mm x 21mm) and my GIANT. Thanks
  21. How many molts?

    question - How many molts do you think it would take an Eldredgeops to go from 11mm (.43") to 64mm (2.52")?
  22. Dunkleosteus armor/possible jaws

    From the album Sharks and fish

    Front side of armor which I believe could be the edge of the jaws! It comes to what would have been the razor sharp shearing edge, greatly worn down now, though. I also believe it could be the jaw because of the clear vertical wear lines on the surface, from being sheared against the inner surface of the other jaw, which is how they kept the edges razor sharp like scissors. I have seen similar wear lines on placoderm shearing jaws, so what I believe to be reasonable observations point to the possibility(maybe even likely?)of being from the cutting edge of the jaws.
