    Carboniferous flora for ID, maybe a bract?

    Hi! I am new here, my name is Óscar and I am a spanish boy (16 years old) that are interested in paleontology, I like specially flora remains he he. Here I have a unidentified fossil from the Carboniferous period, Stephanian B of NW Spain. Terrestrial environment. Could any body say me what could It be? They are two different specimens, and they are incomplete, but they remind me of a bract, since in the large specimen a more elongated area is attached to something else that idk what is It, but it's from the same specimen, in the small specimen you can also apreciate It but bad preserved. Both pieces are the same type of fossil. There are many Aphlebias and Lepidocystis asociated in the area. Thanks you! ^^

    Carboniferous flora for ID

    Hello to all. I ask for your help in ID of the next sample. I have a large collection of Carboniferous flora, but this sample surprised me. First, I will publish standard finds from one mine in the Donetsk region of Ukraine. These Calamites were brought to the surface from a depth of 930 meters. Not flattened and of small diameter - an interesting find. 1476001232_1(5.1).mp4 1697913187_1(8).mp4
  8. Today it was early and about 60 degrees and I decided to go out and do a little collecting. Here are pics of the concretions and some as I found them. As I saw it- As I saw it- As I saw it- As I saw these two- The next piece was large and flat. I do not bring these home, I try to open them in the field or I that is an issue, I break it in half and see if there is anything in the middle. That is rarely the case with these and that was the case today. It is a lot easier this way, saves on the weight that you have to carry. This next one will most likely have a Cyperites. Two more next to each other. As I saw it-
  9. This is an odd one for me, anyone have any ideas?
  10. This evening I had a little bit of time to do some collecting. It was not my best day, but it was still enjoyable. Here is a large Annularia, I was tapping the “crust / outer shell” off of the concretion, and it split open. Also found a nice Lepidostrobophyllum majus. And I am thinking that this is Sigilaria. Here are some concretions as they were found. Sometimes you find concretions near other collectors footprints, as below. I have found concretions next to my footprints, not knowing I missed a piece unti I circled back. Time of day, lighting, etc. are the main causes. Here are my concretions for the day, about 45 of them. I love fossil trackways and found these possible future fossils. The sunset on the drive home.
  11. I decided to do a little collecting again this evening, not that I need any more concretions, but I hear them calling to me. Below is a picture of the concretions that I found this evening. I like big concretions, as most people do, but most do not contain anything, so I leave them alone, like I did to the one below. My favorite concretions to find are the smaller ones, like the ones below. The one pictured below is a nice shape, but not perfect. This larger, flat one is promising, but will most likely be a dud. This next piece was showing both ends, at first I thought that it was two different concretions, until I popped it out. Here are a couple pieces that were found opened. Here is one that I whacked open, I will have to look at it later to see what is included. I was not going to take it, because the shape was not the best. A nice view as I was getting on the highway.
  12. This will be my shortest post ever. I had some time after work to drive the 45 minutes to a site to collect some Mazon Creek concretions. I did not spend much time collecting and only found about 30 concretions, many that I cracked open for a police officer who had asked me how the collecting was going. He was interested and will give the fossils to his kids. Here are a couple pics of open concretions that were in the ground and how they looked after I got them home. Neuropteris ovata- You can see the split open concretion in the ground. Here is an Alethopteris Macroneuropteris Cyperites- Bark-

    8-23-22 Mazon Creek ID

    @connorp @fiddlehead @stats @deutscheben @Mark Kmiecik @RCFossils What do you think? I was thinking that it is possibly an example of Rhacophyllum spinosum, but only about a 51% chance.
  14. I did a little collecting today, found a lot of nice concretions, below are some “in-situ” pictures of concretions and a few pics of some of the open stuff that I found- all Flora. Most of the concretions and the fossils that will be included, will be posted in my “Sometimes you have to whack it“ post. Hopefully this contains a beautiful fern. m

    My first two Mazon specimens

    I had a great, brief opportunity to collect Mazon nodules at a private site. I'm new to this deposit, but really excited to start understand the material. I've started the freeze-thaw on the bulk of specimens, and ordered my copies of the Wittry books, but will post a few specimens that were already exposed or split at the time of collection. Thanks for your help in advance @Nimravis @stats @RCFossils @deutscheben @Mark Kmiecik @Runner64 Specimen 1 (6cm nodule diameter): found as a half, already split. As a newbie, I'm not sure if this anything, but following your guidance to post everything ( @Runner64 @Mark Kmiecik : this is the specimen I thought had superficial resemblance to the example you posted in the other thread). The light region in the middle has some relief to it, as evident in D. There may be a feature that looks a bit like a flower, with a "central disc" and 3 or 4 radiating "petals" with repeating geometric patterning near one edge, visible in B on the bottom right, and in D on the right. Specimen 2 (5.5cm on longest axis): Already quite exposed, with apparent 3d preservation. The bundle of tube-like branches converges at the bottom of A, E. F, H and J offer the view of that bottom. There maybe be a "stalk cross section" of sorts, with a pale central disc and a circumference of notches at the base (best seen in J). There are "tubercles" protruding through the matrix and on the branches (C, D, E). Between this "stalk cross section" and the tube-like branches, there seems to be a rough bark-like structure (H and J). In addition to an ID, I'd love advice on if/how this should be prepped further. The matrix has a network of cracks in it. As I was handling the piece, a small corner of mostly matrix popped off (a small knob of red matrix in F and J is gone in H, revealing a bit of that bark-like structure, but also damaging it a bit, I think). Should I use consolidant to protect it? Can the large large flap of matrix in A and I be removed? Is this a job for an air scribe (which I don't have). I have the sense there may be more tube-like branches under thin regions of matrix in the C and D views (possibly all the way around? G possibly shows the ends of the black branches at the broken top of the piece). Looking forward to hearing what you all think.

    A couple Mazon Creek Flora to ID

    Here are two new Mazon Creek finds I'm not positive on. This first one looks very familiar but I can't place it. The second is a nice 3D piece of wood. My best guess is a Psaronius stem (tree fern), but I haven't found anything like this before so I was hoping for a second opinion. @Nimravis @stats @Mark Kmiecik @deutscheben @RCFossils I appreciate any help.

    8-1-22 Mazon Creek ID’s

    I have two pieces here that are odd and cannot pinpoint an ID, any help from @RCFossils @Mark Kmiecik @stats @connorp @deutscheben would be appreciated. #1 #2

    8-2-22 Mazon Creek ID

    Just came across this piece in a box of loose concretions. It has the look of an insect wing, but believe it might be a Neuropteris inflata leaf. What do you think? @RCFossils @deutscheben @stats @connorp @Mark Kmiecik Sorry for the darker pics, but this is a real black concretion.
  19. Yesterday at work, I ran into a co-worker who knew that I collected fossils. He had me meet him at an area on his property in Coal City that was having some construction taking place and advised me that he thought concretions were there. I started looking around and found a number of them. Unfortunately, this area will covered over today. Below are a couple that I found in situ. I found this big concretions opened and face down. I rubbed it on my pants leg and thought it might be an Asterophyllites, but with my eyes and they way the dirt was moved by my rubbing it, I could not tell. The first thing that I did when I got home was to clean it and this beautiful piece emerged, I wish I had the other half. The fossil it’s self it 5” long and I have never found one like it before. I sent out a couple PM’s for an ID and I am just waiting. I did not get home until after 8 pm and that stopped me from posting more pictures from the collection I just purchased. But actual fossil collecting takes precedent. I also found these two Neuropteris pieces that were opened- this is what they looked like after cleaning. I also have this piece in the car that I just took a picture of- it looks like coprolite, but I will have to clean it up.

    7-16-22 Mazon Creek IDs

    @connorp @deutscheben @Mark Kmiecik @RCFossils Here are a few pieces that I am looking for ID’s on- I believe this first two pieces may be Mariopteris, if yes, what species? I have seen something like this before, but cannot remember where, I am thinking some type of seed? Lastly, I am looking for an ID on this poorly preserved, bushy looking worm. I was first thinking Palaeocampa anthrax, but it just does not seem correct.

    Francis Creek Shale

    The Francis Creek Shale in northeast Illinois is best known for producing Mazon Creek concretions. However, the shale itself also contains an extremely diverse and well preserved flora (and fauna occasionally). Unfortunately, the shale is extremely soft, and quickly weathers to clumps of clay. This makes collecting from the shale very challenging, and most collectors don't even bother trying. On a recent trip I found some fresh chunks of shale and decided to try and save some of the plants. Even working with fresh shale, it was still very hard to extract anything. Larger pieces crumbled easily, flat surfaces flaked as they dried, and some fossils were destroyed just by accidentally brushing a finger against them. These specimens represent what I was able to save. They have been sitting out for over a week now and seem stable as long as they are not handled, but only time will tell if they last. Crenulopteris acadica Crenulopteris subcrenulata Neuropteris fimbriata (seed fern pinnule) Lepidostrobophyllum lanceolatus (cone bracts) On the left is a fern I am unsure of, any thoughts are appreciated. On the right is Stigmarioides. I have not found many examples of this taxa in concretions but it seems fairly common in the shale. I think this is also Stigmarioides. Many of the scars are plugged with pyrite - it was bright gold when I first split the shale but oxidation has darkened it. Hopefully these will last, but if not I wanted to post photographs in case they don't.

    Mazon Creek ID’s

    Here are 3 Mazon Creek pieces that I am wondering about, I will tag the usual suspects. Thanks in advance. @stats, @Mark Kmiecik , @fiddlehead, @RCFossils, @connorp, @deutscheben

    Help with some Pennsylvanian flora specimens

    I have several specimens that look similar, the best of which are attached. The margin of the leaves have deep dentation (is that the right term for it?) or very long fine notches. I found them in central Pennsylvania, in a Pennsylvanian period coal strip mine. Any idea on a genus or species?
  24. My first fossil hunt post. Yesterday (May 29 2022), I went down to the Florissant Fossil Quarry in Florissant Colorado. Its about a 45 minute drive west of Colorado Springs. Its a very well know site partly because of the very well preserved fossils and relative abundance but also because of how easy it is. You pay a small fee and they give you the tools and you pick up shale and start splitting, that simple. You're guaranteed to find something if you try. If you are in the area I would definitely recommend stopping by, its just not really on the way to any popular stops. There is also the Florissant national monument, separate from the quarry, where you can see the massive petrified tree stumps and learn about the fossils in the formation. Attached is an image to show you, I did not take this picture since I didn't go to the monument this time. I had gone prior and really liked seeing this giant fossils. It appears as if it is frowning. The "eyes" are sawblades that got stuck when people tried chopping it down over 100 years ago. You can't use a saw to cut a petrified tree this large though. There used to be many more but they were sold to people all over the world many years ago. Walt Disney even bought one for Disneyland. It was a very nice day at 65 F (18 C). This is what the exposure looks like. You are not allowed to collect from the exposure itself, hence the rope blocking it off. You have to settle for the piles of shale shown in front, which still contain many fossils inside the paper thin shale. The most common fossil besides unidentifiable plant material are leaves. Here are the ones I kept. I believe the next three are of the genus Fagopsis, one of the more common ones. They are 5.7, 3, and 3 centimeters respectively. I measured down the stem, I'm not sure how to properly measure a leaf fossil. Do you measure the stem, the slant height, the circumference? No idea. The next one is the largest one I found, a 7.7cm Willow leaf, family Salicaceae. I am terrible at leaf identification, and all the fossils I found this trip really. I looked through The Fossils Of Florissant book by Herbert Meyer, but still am not certain on many of my finds, so if anyone can identify them I'd appreciate it. From the largest leaf to the smallest, this one is only 7mm long, it split cleanly so I have both sides of it. However some material stuck to both sides. Here's some more leaves for you. 2.3cm Koelreuteria allenii, also 2.3cm 3.7cm for the longer one. 5cm Two and a half centimeters. Three centimeters. The next two seem like they would be easy to identify but I couldn't find a similar picture in Meyer's book. The first one is 2.4cm long and the second, 1.5. The detail that is persevered is incredible. It looks just as detailed as a leaf I could find in my front yard. Here's a close up of the leaf above. The "circle" has a 10mm diameter. This one is a winged maple seed, likely Acer macginitiei and is 11mm long. A knot on some wood, only 5 mm long. Here are the insects. Only 1.5mm long. The wings are barely visible. This one looks like a fly, order Diptera. I have both sides, unfortunately the other one isn't very good. Its half a centimeter long. This one is also a fly I'm guessing. Its 4mm long. An odd one, 5mm long. An unknown larva. Its 0.4mm long. Florissant is one of the rare places where eyes can be preserved. And last but not least are the four gastropods I found. They are very tiny but very interesting. The first one is only 3mm wide. It was split open so I have the positive and negative. This one is only 2.5mm wide, possibly the best preserved out of the four though. The "large" one, 4mm long. This one is also about 4mm long. The first and fourth gastropods are a yellow color whereas the other two are a pearly white. That's everything, I hope you enjoyed it. Again, thanks if anyone could ID anything, and thanks for reading this far and looking at the photos. I truly appreciate it.
  25. For the last 4 years I have been collecting plant fossils from sites in East Central Illinois. These fossils were all brought to the surface by underground coal mining in the first half of the 20th century. Most of the spoil piles in the area have been graded or flattened out, but a few still remain, standing tall above the flatland. One particular pile is, I believe, the source of most or all of the fossils I find. The shale that makes up the spoil has been fired by the internal heat of the pile, resulting in the hard, reddish material known as "red dog". This shale is then crushed and used as paving material, on trails, parking lots, and construction sites in the area. It's at these secondary locations that I am able to search the material for the impressions of ancient plants and collect them. The shale is pretty smashed up, so complete or large fossils are rare, but the preservation of detail is generally quite good. Geologically, the fossils come from the Energy Shale Member of the late Pennsylvanian Carbondale Formation.
