  1. Here is a few of my Lucky finds for 2019 Mazon Creek fossil collecting season. I will try to keep adding to it as time and posting ability permits. My wife and I collected 14 times in 2019 at 4 different areas. We had a great time, met many great people, learned a great deal, on our adventures. Anyhow, I'll give this a try, and apologize in advance for the less than perfect photos. Phil

    Mazon Creek Flora

    I've been spending a lot of time lately studying the Mazon Creek flora, and am continuously astonished by the diversity and quality of specimens that can be found. I don't think we see enough plants on the forum, so I figured I would go ahead and share some of my favorite finds. First is a specimen I recently shared, and a fitting start to the thread. This is Crenulopteris acadica, the most common true fern found in the Mazon Creek flora. It has been the most common plant I find, accounting for probably half my finds. Next is a favorite of mine. This is a s

    My Mazon Creek Finds

    I will be using this thread to post what I have found fossil hunting in the Mazon Creek area, including the ESCONI Braceville pile, Mazonia/Braidwood, and any other sites I get a chance to explore. Although I had been to Mazonia a few times previously with virtually no luck, my first successful trip was with ESCONI last September at the private spoil pile they have access to. These first fossils are all from there. I have tried to give the best IDs I can- please jump in if you think I have anything wrong. I also forgot to put something in for scale on this first batch of photos, my apologies.
  6. I thought I jump on the bandwagon of Mazon Creek and show my little collection. I’ve been picking up the odd fossil here and there to add to my allotment. This has been over the last 5 years. Originally I was introduced to the ironstone concretions by Ralph in one of his great auctions to support TFF, which I was lucky enough to win. The first 3 added after the collection photographed in the drawer, I could do with a little help for identification please. 1: sea cucumber, 2: worm, 3: Has a label but it is only the seller’s info ? thank you help and for looking.

    Mazon Creek Collection

    I'll update this thread with my Mazon Collection over the next few weeks. With some good weather out yesterday, I managed to get my first fossil hunt in for the season and will post a report in this topic. I will be moving this upcoming summer which will put me even further from Mazon Creek so I have purchased a few pieces to fill in the genus/species I haven't found yet and will mention if I purchased a fossil. I still hold out hope to find some of these pieces I purchased eventually but will realistically be difficult if I only can make 1 trip a year. Fauna Tullimo

    Mazon Creek Lungfish plate?

    Had this concretion open today. I'm pretty confident it's something vertebrate. Maybe a lungfish plate? @jdp @RCFossils Thanks for any help.

    Mazon Creek 8-28-21

    Fossil Forum members were well represented at the Illinois Canal Corridor Association's Mazon Creek collecting event this weekend. My wife and I were able to make the 11 hour drive out Friday to join them and we enjoyed a productive afternoon in the creek Saturday gathering several buckets of concretions to take our first crack at freeze thaw. We also found a number of already opened specimens to wet our whistle while we do our best to be patient. Here are some of our better finds even if some are a little water worn. New to us, so the trip is already a success regardless of what

    Aphlebia spinosa?

    Can anyone confirm that this Mazon Creek specimen is of Aphlebia?
  11. A couple months ago I received a message from a friend letting me know of an opportunity to collect a usually inaccessible Mazon Creek site. The area used to be a popular with collectors but has since been reclaimed as a subdivision. A house was finally being built on one of the last undeveloped lots, and this meant spoil piles while the foundation was being laid. I initially planned to go later in the week, but instead decided to wake up early the next day and drive down. This ended up being a lucky decision, as the foundation was filled that very next night. The site was not superbly product

    Mazon Creek ID help

    I'm not quite comfortable with the possible IDs offered for these three fossils. Again, I sincerely thank anyone who chimes in with even a guess. A0003 -- Myalinella sp. or other bivalve, or something else? It has been suggested this is a Coprolite. C0004 -- Lycopod leaf upper end both halves? The part that looks like Coprolite has a "peanut shell" pattern in the hollow of the half on the right. C0085 -- Cyperites? I'm not convinced. Not comfortable with the taper. Perhaps a spine, either plant, arthropod or marine?

    Four more Mazon Creek for ID

    Four more for ID or confirmation. Again, thank you for your help. A0003 - Myalinella? Other? C0056 - Orthacanthus? C0086 - I have no idea! E0015 - Cyclopteris or Macroneuropteris basal pinnule? (venation forks)
  14. Mark Kmiecik

    Another four more Mazon Creek for ID

    And another four that I need help with. Thank you in advance. E0021 - Pecopteris? Other? E0040 - Mariopteris? Neuropteris? Best guess? Venation not clearly visible. E0098 - Cyclopteris obicularis? This one I'm fairly sure of. I0002 - Paleocaris typus? Acanthotelson? Other?

    Four Mazon Creek for ID

    Here's four more with which I need help identifying and/or confirmation of ID. Thank you. C0004 - You tell me and we'll both know! C0047 - Calamostachys? Bowmanites? Other? C0052 - Coprolite? No, it's not a fish. C0055 - Mariopteris? Neuropteris? Other?
  16. I was inspired by @Mark Kmiecik and his quality photographs to finally learn some basic image editing. I had this beautiful Crenulopteris acadica fern open yesterday and figured it would be a good specimen to make a first attempt. Let me know your thoughts.

    Mazon Creek Fern

    From the album: Miscellaneous

    Pecopteris sp.? Mazon Creek Not experienced with flora, so ID is uncertain.
  18. For the most part, fertile ferns are rare in the Mazon Creek flora. The only exception being Diplazites, of which ~1/2 of all specimens are fertile. This is my first non-Diplazites fertile fern. I really like the interplay between the white mineral deposits, the brown matrix, and the scattered pyrite crystals - a very artistic specimen I think. My best guess is that this is Cyathocarpus hemitelioides, but I am not positive. Close up of a fertile pinnule Close up of sterile pinnules at the base

    Need species ID, if possible

    Three more Mazon Creek fossils for your consideration and hopefully ID to species level. Thank you very much in advance for all the help I'm going to need. Crenulopteris acadica ? Lepidostrobophyllum ovatifolius ? Lepidostrobophyllum lanceolatus ?
  20. Mark Kmiecik

    Mazon Creek specimens for ID

    I have six more MC specimens that I need help with identifying. Again, down to species level if possible. The only one I'm fairly sure of is the Coprolite.

    Request for ID of Mazon Creek specimen

    Might anyone be able to put a genus (and species?) to this Mazon Creek specimen? The nodule itself is about 4" in length. It may be a polychaete—or not. Thanks! I appreciate your expertise. IMG_0178 copy.tiff

    3D Mazon Creek Jigsaw

    Sometimes, when you freeze/thaw Mazon Creek fossils they split more than just in half. Sometimes you get 3 or 4 pieces. Sometimes you get 47 larger ones (more than 1/4") and LOTS of tiny ones. You make the best lemonade you can with the lemons you've been given. Here's a "before" and "after" of one I repaired today. Unfortunately, too much of the surface detail crumbled into pinheads and powder. Would have been a real beauty if nature wasn't as cruel as it is.
  23. Hoping for confirmation and/or species identification. Thanks in advance. Not sure of much anymore with all the recent changes. Annularia inflata? Alethopteris serlii? Calamites cistii? Pecopteris? Crenulopteris? species? Pecopteris? Crenulopteris? species?
  24. A couple weeks ago I ran into a former collecting friend at the ESCONI Show. I had not seen him in about 20 years and we talked about the old days and my fossil mentor Walter Lietz, who we both collected with. In the course of the conversation he mentioned that he had a collection for sale, not his own, but another family member. I advised him that after I got back from MAPS, that I would like to see it. Today I drove the 30 minutes to his house and took a cursory look at the totes of fossils. After looking at the stuff, we came to a price and I brought the fossils home. It contains all differ
