  1. Rockpit


    I found this nodule last summer and opened it about a month ago. Could it be a worm? I didn't know if the two adjoining dots on the left were jaws.

    Ginkgo leaf or something else?

    I am wondering if this is a Ginkgo leaf or something else? Looks like a Mazon Creek fossil to me.
  3. I am at a 99% certainty that this is just a weathered annularia, but there is a very small percentage of my thinking that it might be the cephalopod, Jeletzkya douglassae. I know that J. douglassae has 10 arms and this concretion has 9 branching (leaves / arms?). I collected this 1/2 concretion years ago at Pit 4 (Shadow Lakes- Braidwood Flora / Fauna) What do you think @fiddlehead, @RCFossils?

    Mazon Creek ID help

    Hey Everyone! Happy new year! A nodule from South Pit 11 Mazonia area split and can't figure out what it is? Millipede? Shrimp tale? I have the Wittrey book I've been looking through and I see similar features on multiple animals from his pictures. Thanks for your help!

    Mazon Creek fish scales

    I am asking for help identifying the species of some fish scales from Mazon creek. The scales were too small to put a scale in, but the whole patch is about 1.2mm in width. On the reverse side of the concretion it appears there are some spines under the scales, possibly from the fin. My initial thinking is Rhabdoderma Exiguum as the fin looks similar to me as an example from RCFossil's collection:
  6. Last weekend, since the weather was supposed to be nice and my wife was out of town, I decided to get out and collect from three Pennsylvanian sites in Illinois and Indiana. On Friday, I took the day off work and headed down to the former Chieftain no.20 mine site south of Terre Haute, in what is now the Griffin Bike Park. It was an overcast day with a slight drizzle and I had the park all to myself. I found a nice assortment of nodules, including a few split ones with ferns- the one on the left, although preserved in three pieces, is my biggest one yet from this si

    Mazon Flora help

    I've had a few specimens in my collection that I have questions about and am seeking some clarification. #1 another view #2 #3

    Mazon ID Assistance - No.5 egg case?

    I have a Palaeoxyris that is significantly larger than this specimen. Is this a Palaeoxyris, and why would there be such a discrepancy in size between specimens?
  9. Jones1rocks

    I Lied

    Sorry, I forgot about this one. If I post another within two weeks, I promise to distribute my entire Mazon collection among you all. Offer void in the United States and other countries. I think I know what this is, as I see a similar image of one in an RCFossils album. But just to double check, this is what I believe it to be: Mamayocaris Jaskowskii.

    Mazon Unknowns - Slug?

    To all of those who have made suggestions, educated guesses, and definitive identifications: This is the last one I currently have a question on, and I want you all to know that I have appreciated all of your efforts in helping me to understand and identify some of my more problematic specimens. I have learned a lot from the information on The Fossil Forum, the galleries, and from comments and links provided by everyone. Most of all, I have learned that I know very little, and that makes me appreciate your knowledge even more. Thank you so very much! ~Paul
  11. I was watching the Clint Eastwood movie “The Good, the Bad and the Ugly” recently and it made me think about collecting Mazon Creek concretions and how the movie title applies to them. Let’s start with a couple of the “Good” things: -Over the years there has been numerous books and articles written about the Mazon Creek area and concretions and they provide outstanding information for the collector of all levels. -With about 400 species of flora and about 320 species of fauna that are found in these ironstone concretions plus the remarkable pres

    Mazon Uncertains - 7 ?

    What I first thought to be a Cyclus, after photographing with shadows, looks kind of like a jellyfish (Reticulomedusa?).
  13. Jones1rocks

    Mazon Uncertains - 9 ?

    The first and last ever discovered baby bottlenose dolphin to be found at Mazon Creek! How lucky am I? Not a clue.
  14. Jones1rocks

    Mazon Uncertails - Tully?

    Really don't have much of a clue, but think I'm seeing a tail fin at the very least.
  15. Jones1rocks

    Mazon Uncertains - 6 snails?

    One that I initially thought was a coprolite, after photographing and zooming in, I believe I'm seeing a large group of tiny snails.
  16. Jones1rocks

    Mazon Uncertains - 4 ?

    I think I see body structures here, but I'm at a loss.
  17. Jones1rocks

    Mazon Uncertains - 3 shrimp

    Another Acanthotelson Stimpsoni ?
  18. Jones1rocks

    Mazon Uncertains - 1 jellyfish?

    This looks very similar to one I posted yesterday, but this one has a very defined outline. My guess would be Essexella jellyfish, or possibly coprolite. It's a little bugger.
  19. Jones1rocks

    Mazon Uncertains - 2 worm?

    This could be a leaf of some sort, but if so, I don't think it would be typical of Mazon fossils, so I'm inclined to suggest a worm.
  20. Jones1rocks

    Mazon Uncertains - 10 ?

    Are these leaves or wood, or nothing at all?
  21. Jones1rocks

    Mazon Uncertains - 5 shrimp?

    I always thought this was the digestive tract of a worm, but after taking the pictures, I'm fairly convinced that it's a shrimp of some sort.
  22. Since @Jones1rocks has been posting Mazon Creek fossils for ID's, I thought that I would post two that have stumped me and I would appreciate any help. Both of these concretions look similar to me- the first one I only have a half and the second one I have both halves. Sometimes I think that they are flora and other times I think fauna- such as a shrimp, but I have no clue. I am really leaning towards fauna and I have never found any others that are similar. Here is the one with only 1 half- different views:

    Mazon ID Assistance - No.6 ?

    I'm doubting my initial thought that this is a leaf impression. It very much resembles some bark imprint images I have seen, but some of the other visual characteristics are misleading. Any thoughts?
  24. I'm thinking that this is probably Didontogaster.
  25. Jones1rocks

    Mazon ID Assistance - No.7

    I have not seen any definitive images of leaves of this exact shape and pattern yet. The closest I can find is one of RCFossils images: http://www.thefossilforum.com/index.php?/gallery/image/11888-alethopteris-serli-rcmc0058ajpg/&browse=1 Do you think it's the same?
