    A Fossil A Day.....

    A Fossil A Day....keeps the blues away! Or something like that... I started an Instragram account (jamielynnfossilquest) and am posting a fossil a day, so I figured I should do that on here, to REAL fossil enthusiasts! I'm a few days behind, so I will start out with a few more than one a day but then it will settle down to One Fossil (but I will admit, I'll probably miss a few days, but I'll double up or whatever.) I'll start with Texas Pennsylvanian era, but will branch out to other locations and time periods, so expect a little of everything! So enjoy A Fossil A Day! Texas
  2. DPS Ammonite


    This fossil with faint triangular outline is covered in a bryozoan was found in the Pennsylvanian Naco Fm. near Kohl’s Ranch. Is it a flattened conulariid? 2 cm coin for scale.

    Ambridge Pennsylvania fern question

    Just curious if these are fern seeds??? During the summer, I slipped over to Ambridge, Pa. to collect a few ferns. Multiple nodules were discovered and the more I thought about it, the more I became suspicious of "seed". Thanks for looking. I am very uneducated when it comes to plants. Mike
  4. I went on a trip to the Braceville spoil pile (Pennsylvanian deposits of Francis Creek shale, similar to other Mazon Creek locations but more marine) with the ESCONI club last week. Some of my concretions have already opened and there are a few things I am not sure about. Most of these might be totally unidentifiable, but just in case wanted to check - any input would be great. 1. I think I see some resemblance to a partial whorl of Spiropteris (curvature, and it seems like there are 1.5 whorls present). Could that be the case or it just some miscellaneous plant bit?

    Mazon Pit 4 concretion

    Hello! I had the privilege of joining ESCONI to Mazon’s Pit 4 yesterday and came across this concretion. There’s a very good chance it’s nothing, but I thought the 3D shape might be peculiar. The concretion is about 1.5 cm wide in total. Thank you for looking!

  10. Hey there!! I’m back with a few more pictures of my finds from Corys Lane in Rhode Island. Being a beginner I’m slowly getting a hang of fossil hunting but sometimes you always find some cool looking rocks that convince you otherwise and you hope they’re a fossil. So help me out to determine if these ones are maybe a fossil or just a cool find. Also this trip was very fun and the most productive so far. The weather was cloudy accompanied by a cool breeze, not too many people on the beach during low tide. Only a few fishing hobbyists very curious about what we had caught in our buckets. Th

    Glikmanius occidentalis tooth

    From the album: Pennsylvanian fossils

    Phylum: Chordata Class: Chondrichthyes Order: Ctenacanthiformes Family: Ctenacanthidae Genus: Glikmanius Species: Glikmanius occidentalis Unfortunately, this is as far as I can prep with a box cutter.
  12. This came from a bucket of material from Jacksboro Texas donated by @GaryTurner for the Dallas Paleontological Society fund-raising auction, so it's Late Pennsylvanian, Graham Formation. The surface resembles a bryozoan but I haven't seen one with this shape. Scale is millimeters.
  13. I'm taking a feather from @Nimravis and starting a thread about repairing Mazon Creek fossils. I use the freeze/thaw method, but I do tap them lightly once in a while. That usually isn't what causes concretions to fall apart. Water creeping into the rock finds all the weak spots and sometimes a concretion basically shatters. Some localities are have hardier concretion than others. I have found that Pit 2, 3, and 4 have great preservation, but Shadow Lakes isn't referred to as Shatter Lakes for nothing. Super glue is nice, but I generally use Elmer's Glue as you can

    Carboniferous Fish? Curiosity

    I just don't know what this thing is. It's from the Glenshaw Formation of Allegheny County, Pennsylvania. Some is below the matrix, but what is showing is about 1 cm top to bottom and 1.5 cm across. I believe it is Brush Creek Limestone and it looks like part of a fish spine to me. As always all help is appreciated. Thanks.
  15. I gathered these fern fossils from Cory’s lane in Rhode Island recently. Need some help with their identification. My guess is they look like Pecopteris but any more specific identification would definitely help.
  16. I am new to micros but I have had at least a cursory look at bulk samples from a variety of sites and ages, mostly Texas and Pennsylvanian. The material from this one Pennsylvanian site in Oklahoma seems so far out of the typical range for quantity of fossils I am wondering what others think. Most of what I have looked at will show me a fossil for every 50 to 100 rocks and I consider that normal. This site has matrix that, when cleaned and screened to remove the finest shale particles (60 mesh) has hardly anything but fossils! The biggest problem with that is deciding what to keep and what to

    Pennsylvanian Tooth-Shaped Fossils

    Hello! I think I've just about tapped out most of my local hunting spots. Yet a week ago I found a couple fossils that look like teeth. Please let me know what you think. They are 1.5 cm wide by 1 cm long, Pennsylvanian (Carboniferous), Glenshaw Formation and from Allegheny County, Pennsylvania.
  18. Sometimes it could be accurately said a fossil hunting trips most intriguing finds are discovered after bringing the fossils home. That's exactly what happened after my Sunday/August/19/2023 trip with @Tales From the Shale at some Late Pennsylvanian rock formations in Illinois. Lots of brachiopod, bryozoan, and pretty awesome Chondricthyan teeth were found on this trip. But it was at home that I accidentally uncovered a pretty remarkable find I would like help getting a Proper ID for. On Wednesday around 10:00PM EST, I decided to break open with a pretty large hammer so
  19. On Sunday/August/19/2023, myself and @Tales From the Shale went fossil hunting at some Late Pennsylvanian rock formations in Illinois! It was a pretty productive trip! We found lots of brachiopod fossils and an awesome amount of Chondrichthyian fossils! There are some fossils though that I'm a bit confused on their exact ID and I would like help identifying them? I put and photographed some of these specimens under a microscope and dissecting scope to help with species/genera identification. Here are the various and pretty awesome specimens from the trip I would like h

    Glikmanius? Pennsylvanian fish tooth

    Went to look for trilobites at one of my favorite localities. No complete trilobites that day, but I did spot a neat little tooth instead. I did some prep hoping it could be identified, and will finish it soon. I thought the root and multiple side cusplets compared well with Glikmanius occidentalis, but of course I always welcome more opinions. I forgot to add a scale, but the exposed portion of the tooth measures 2 cm in length. as found after some cleaning
  21. Location: Warrensburg, Missouri Period: Pennsylvanian Formation: Unknown Hello! I happened to have had an opportunity to visit land owned by one of my friends and decided to split some of the black shales. I happened to come across something that seems familiar but I just can't seem to place a name on it as of yet. So far I have found 2 specimens, and I'm not sure if one is just infilling of the original mold or something other. Unfortunately they were in already weathered sections of shale and I could not retrieve the other halves of the shales. In case it helps with i
  22. Hello everyone! I've been inspired by so many good Mazon Creek topics in this forum, I thought I would start my own. I'll post my own finds, which so far don't include anything as exotic as a Tully Monster, but maybe I'll get lucky on page 134 or so... I have to credit my kids with getting me interested in fossil collecting. I was always interested in rocks and fossils but when my 10 year old son had his dinosaur phase it really sparked my interest again. I wondered if an ordinary person like me could go out and find fossils? So I Googled fossil collecting and found out that not on

    A Trip to Cory’s Lane

    This afternoon I headed to Cory’s Lane for some digging. I unfortunately completely forgot about the tide, but thankfully it wasn’t very high when I arrived. A group of four was already there, and they said they didn’t find much “except for maybe a piece of grass.” The shale is very crumbly and oily, and virtually blank most of the time, so my hopes were not very high. I did find some decent, albeit very badly preserved ferns. Identification of these is very much welcomed, as I don’t know much about these. Rhode Island Formation, partially metamorphosed. My first find, Crenulopteris?
