    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

    I Have No Idea What This Is

    I have no idea what this thing is. I found it in Allegheny County today in the Pennsylvanian Glenshaw Formation in what I think is Brush Creek Limestone. Unfortunately it is only part of the fossil, but I thought the pattern might tip someone off as to what it is. Scale is in metric. Thanks for the help.

    2023 Mazon Creek trips

    Hey everyone! Haven't posted here in a while, and thought I would come back with a trip report. Recently I became interested in Mazon Creek fossils - something unusual for me as a vertebrate person. I finally managed to get out in the field this spring and visit the Mazonia-Braidwood State Park and the Braceville spoil pile through an ESCONI trip. I have collected at quite a few Paleozoic sites before, but this was my first time hunting in the Carboniferous! I went to Mazonia with a friend on a weekend in early April, when there was no foliage and it was sunny outside.

    Trip to Oglesby 5/27/2023

    To really start the summer off well, I went recently to a Bond Formation rock formation of Pennsylvanian age, around 300 Million Years ago, in Oglesby Illinois with a few friends. The trip was overall good, though I almost fell off the rocks a couple times. It was a bit hot but overall I think I got a decent amount of fossils for the day. I found a decent amount of Crinoid stem fossils, of which here are a few of them: Found lots of what I think are Chondricthyian teeth (Chomatodus, Gilkmanius, etc.). But I would like help identifying them!!!
  5. I found this piece on Friday. I thought it was wood, hammered it out, collected it in a tiny bin, and took it home. Saturday evening I put it under the scope and was surprised to see the texture. I've collected wood before and the grains are typically tighter. It also looks very similar to recovered Petalodus or fish root material I've seen. This deposit has a lot of different shark teeth, at least four unique genera are present. The limestone has the characteristics of a dynamic wash, where a lot of material was gathered and deposited quickly. Not that it helps a lot. I've never f

    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

    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

    Backyard Trip

    My folks have a nice lake behind their house. It is relaxing to spend a warm evening watching a heron spear fish or geese fight each other. Or watch silt slowly fill the lake bed. Across the street, a housing developer stripped off a bunch of soil down to the bedrock, but ran out of money before building on the land. This has resulted in some significant erosion and sedimentation in the lake, but this cloud does have a silver lining. I soon noticed a thick bed of shale exposed on the hill. So it was only a matter of time until I make the short trip to the top. The hill,

    Pennsylvania’s Carboniferous Fauna

    I am seeking info on Pennsylvania’s Carboniferous plant fauna. The ID plates I currently have access to are ok, but lack info beyond ferns.

  13. I'm in the process of photographing and cataloging specimens from a new site and thought some here might enjoy seeing some specimens as I go. These fossils were collected in eastern Illinois from the roof shales of the Herrin (No. 6) Coal. They are middle Pennsylvanian (Desmoinesian) in age. The Herrin (No. 6) Coal is the second to last coal member of the Carbondale Formation. For reference, the Mazon Creek biota occurs in the Francis Creek Shale Member, which overlies the first coal member of the Carbondale Formation, the Colchester (No. 2) Coal. Here's a general stratigraphic section of the

  15. Last Thursday decided to get out to Pit 11, Mazonia South Unit, Illinois for a day of collecting nodules and fossils. We've had a lot of rain and Thursday was clear. With all the rain, nodules are easier to see when wet as they jump out as a bright red compared to the green forest floor. And the rain hopefully erodes some fresh nods out of the ground. I sometimes go on foot for collecting but thought I would break out the kayak to get to where I need to go more efficiently. The woods are getting quite overgrown already but I haven't been out much th

    Limestone Pennsylvanian Mystery

    I have no idea what this is. It's unlike anything I have found. I split it out of Brush Creek Limestone today. Pennsylvanian Period, Glenshaw Formation. It's about 25 cm in circumference at the base. I would guess cephalopod, but it's much bigger than one's I've previously found. Help is appreciated, thanks!

    Fossil ID help!

    I found this fossil imprint while looking for arrowheads out in a farm field today in Parke County, Indiana (west central indiana). I’ve found a number of fossils from the area in my life but have never seen one like this. Anyone have an idea? The imprint does not continue around the other side of the rock. What you see in the image is all that’s there.
  18. Please help ID these Pennsylvanian Naco Formation trace fossils from central Arizona. Help Chris. @Arizona Chris Are the 1 cm wide chevron tracts in photo 3 Cruziana from trilobites? What are the 2.5 - 3 cm long teardrop shaped features in photos 1 and 2? What are the 2.5 - 3 cm long teardrop shaped features in photos 1 and 2? What are the elongated traces 3.5 to 4.5 cm long with length parallel marks in photo 4? From crustaceans?

    Pennsylvanian fish tooth

    Stumbled upon a cool looking partial tooth. I'm not the best with IDing teeth, but I think this might be a Cladodont tooth? It has side cusplets. The tooth root measures 1 inch across.

    Too big for a conodont?

    This came from the Deese Group of central Oklahoma. It seems a little long for a conodont at 7 mm but it doesn't look familiar to me. Any ideas?
  21. As promised, my second trip report covering my day trip last October to the two most famous Pennsylvanian-aged fossil locales in Texas is here! That same Saturday after visiting Mineral Wells and finally finding my first trilobites I made the hour drive north to Lake Jacksboro. For those who don't know, the Lost Creek Dam on the southeastern side of Lake Jacksboro was constructed from earth dug out of a borrow pit a short walk away. As the lake and its dam happen to sit on top of the Finis Shale Member of the Graham Formation (although there is debate that , which dates back to th

    Pennsylvanian arthropod bit

    Maybe a long shot, but I'm hoping someone might recognize this. It looks like a piece of some arthropod exoskeleton to me, but further than that I have no idea. It was collected in the Pennsylvanian of Illinois. The site it collected from is terrestrial/freshwater. It is dominated by plants but has produced bivalves, branchiopods, and shark egg cases – typical fauna for a site like this. Some other possible arthropod bits have showed up, but nothing obviously identifiable. I would expect horseshoe crabs and/or insects will show up eventually, but nothing definitive yet.
  23. Found in Southern Oklahoma among other Pennsylvanian fossils, crinoids, brachiopods, etc. Specimen is .5cm across. 6 sided. Looking for help with ID.
