  8. Platyceras

    Does anyone know what species of Platyceras have been found in the Cedar Valley Formation/Devonian of Iowa??
  9. Upper Devonian Fossil Guide?

    Yesterday, I was participating in an Open House event with my local mineral club. I had a display of fossils, minerals, and American Indian artifacts from New York state, and found that the person assisting visitors at the door was sending all of the people who brought fossils in to my table. This was lots of fun, but I rapidly discovered a problem with the two fossil guide books I own: while they both have a lot of information about Lower and Middle Devonian fossils, there wasn't enough breadth on Upper Devonian for me to really give a positive ID of anything found locally! The best I could manage was to point to a Middle Devonian species and say something like "The holes in your rock look a lot like the impressions that on of these brachiopods, Pseodoatrypa devoniana, might leave, but those were earlier and didn't get that big. I don't know what your fossils are other than something similar." Can anyone recommend a good resource for Upper Devonian material? What I currently have are the two PRI publications on Devonian Fossils of New York (one by Linsley, the other by Wilson).
  10. Is this a crinoid holdfast?

    I was wondering if this is a crinoid holdfast. Area is 2 cm x 2 cm Found in the Devonian of Indiana, Kosciusko County.
  11. From a long abandoned bluestone quarry in NE Pennsylvania. Devonian, Catskill formation. Found by my sister-in-law, who was really looking for live birds! Ideas?
  12. Iowa Devonian Fossil (Fish Armor?)

    Help please! Last weekend I was on a club trip here in Eastern Iowa, and I found a really cool fossil. According to other club members, the layer it appeared to come from is roughly 385 million years old, possibly from the Little Cedar Formation, although we can't be sure. We believe that it is likely plating from an armored fish. A photo with a couple measurements is attached. The bumps vary in size, but are about 3 mm in diameter. I've reached my photo size limit, so I will try to add more close up photos in a little bit. What species could this be? What part of the body would it be from? Thanks! -Ben Worrell
  13. chelicerata rossica

    Marshall_et_al-2014-Palaeontology.pdf A DIVERSE CHASMATASPIDID (ARTHROPODA:CHELICERATA) FAUNA FROM THE EARLY DEVONIAN (LOCHKOVIAN) OF SIBERIA by DAVID J. MARSHALL, JAMES C. LAMSDELL, EVGENIY SHPINEV and SIMON J. BRADDY Palaeontology, Vol. 57, Part 3, 2014, pp. 631–655 Key words: Palaeozoic, Chasmataspidida, Heteroaspis, Dvulikiaspis, Nahlyostaspis, Skrytyaspis, convergence. "two novel chasmataspidid species: Nahlyostaspis bergstroemi gen. et sp. nov. and Skrytyaspis andersoni gen. et sp. nov. ‘Eurypterus’ stoermeri and ‘Tylopterella’ menneri are both redescribed as chasmataspidids, having previously been assigned to Eurypterida."
  14. When I was cleaning up scraps of shale from my prep floor today, I saw parts of trilobites on some of the pieces of shale. The rock was collected recently and a complete Eldredgeops was removed. This shale is Middle Devonian in age and is very hard (almost like limestone). Trilobites in this layer are well preserved and 3D. The trilo parts I found were the cephalon of a small Pseudodechenella, pygidium of a Greenops, and the eye of a Dipleura. I spotted the Dipleura as just a small piece of exoskeleton in the side of the shale. I knew it was a piece of Dipleura shell, and I knew it was just a piece, but I was curious. The fossil was lying on a crack in the shale that I easily split open with a small chisel. When the eye popped out of the matrix I thought it was pretty funny and said to my girlfriend "well i'll be darned".
  15. Crinoids

    Are these the same things, and if so, what are they?
  16. Microtektites?

    Any experts on microtektites out there? That was my second thought. First thought was some kind of anthropogenic contaminant. They don't look entirely inconsistent with some microtektites I've seen. These are from Devonian micro- matrix. The smooth one is heterogeneous (laminated?) and has air bubbles. Scale is 1mm.
  17. This collecting trip was more of a scouting expedition than an actual dig. After the snow and ice have melted, its fun to get out and see whats newly exposed/uncovered. Today we found the usual cast of characters like horn corals, tabulate corals, brachiopods, gastropods, pelecypods, and trilobites. I was mad at myself for not having faith in a trilobite fossil that I found on this trip. It was barely visible in the rock I found it in and I thought it would be incomplete just on how it looked. I started to remove the matrix (hard limey shale) with a hammer and small chisel. The bug popped out of the rock complete and fell on the floor. The trilobite landed on its glabella and some of its shell broke off. I think I found all the pieces but I should have been more careful. After all these years of collecting I should know better. I promised myself to make up for it and that I would find a killer bug this season with some new sites that I have lined up Thanks and Happy Collecting mikeymig
  18. Bactrites sp.

    I've been cleaning up a few boxes with devonian fossils from the past few months and came around this nice little fellow. I cleaned him up and gave him a paraloid treatment to preserve the pyrite. It is a complete specimen of a Bactrites sp. from the Matagne shales ( Frasnian, late Devonian ) from Belgium, both phragmocone and body chamber are preserved. They are a little unusual, as the do not belong to the nautiloids as his first appearance might suggest but they have their own subclass and are considered to be the ancestors of the ammonids ( they have a ventral syphuncle like all the ammonoids ) Fragments of them often pop up from the shales, but I rarely find them complete. This one is going in the display cabinets
  19. To celebrate the end of the semester, I decided to finally take the 2 hour trip down to the Paulding Fossil Gardens. The weather sucked as most of you in the Midwest probably noticed, but I managed to get a few hours in between storms. This made everything a bit flooded, but I wasn't too concerned.
  20. Is this coral?

    I presumed this to be just coral until I saw some pics of bryozoans that looked liked faces. Is this coral?
  21. Devonian cephalopod collection

    I finaly got around putting all my best cephalopods specimens that I collected over the past 4 years in the frasnian of southern Belgium on there place in the cabinets. They all come from the same location. (except an orthocone and a receptaculites from the same age but from a different spot ) most of it has already been posted in individual posts, but this gives an overal vieuw of the part of the collection on display. Enjoy al the Manticoceras, Crickites, Tornoceras, Bactrites, Orthocones and more
  22. Brachiopod interior?

    I was wondering if this is a brachiopod interior, and if so, could it be rafinesquina?
  23. Is this a blastoid?

    I found this on partridge point in Alpena MI in Devonian limestone and have been finding crinoids and blastoids. I’m not sure what this is.
