When it comes to fossils, I am a generalist by nature. I haven't met a fossil that I didn't like! However, in an attempt to narrow my focus a bit, I have decided to take a cue from Adam ( @Tidgy's Dad ) and start this thread. I hope to showcase some of my collection, but more importantly have a central place to post IDed specimens, information I have found regarding them, and/or ask for help with IDs. Hopefully other's will get enjoyment from seeing the specimens and potentially learn a thing or two. So come along on my journey through the Carboniferous! If you haven't had the pleasure of getting lost in the Cambrian, Ordovician, or Silurian with Adam, you are doing yourself a disservice! I highly recommend his below threads. Adam's Ordovician Adam's Silurian Adam's Cambrian Now, let's go! Kentucky is known far and wide by fossil collectors for being within the Cincinnati Arch, and having wonderful Ordovician fossils, but what many fail to realize is that the Ordovician makes up a small percent of Kentucky's exposed strata. By far the most represented time period is the Carboniferous. With Central to Western Kentucky being mostly Mississippian in age, and Eastern Kentucky (and part of Western) being predominantly Pennsylvanian. There is a reason that coal is big business here! A simplified version of Kentucky's geological survey map, but it gives you a good idea of the distribution of what can be found. Image borrowed from: Bryson, Lindsey & Gomez-Gutierrez, I.C. & Hopkins, T.C.. (2012). Development of a new durability index for compacted shale. Engineering Geology. s 139–140. 66–75. 10.1016/j.enggeo.2012.04.011. An adaptation of the KGS map found here https://www.uky.edu/KGS/geoky/index.htm I'm lucky enough to be within an hours drive from most represented time periods. Excluding the Tertiary/Cretaceous and Quaternary, but I live in the Mississippian area and find myself hunting that time period more often than not. The Mississippian here is mostly marine in nature with brachiopods, corals, bryozoans, and the like, being the norm. While the Pennsylvanian is a mixed bag of marine and terrestrial life. More information regarding the geology of Kentucky can be found at the Kentucky Geological Survey website here. I would also recommend the open access papers below regarding the Carboniferous and it's invertebrate fauna. I have not studied terrestrial and vertebrate life much yet, but will showcase those finds and related research material as they come. Mississippian Fauna of Kentucky Pennsylvanian Invertebrate Fauna of Kentucky The fossils will come next, and I plan to post a new one regularly (Daily? Weekly? Monthly?) as time permits. So sit back, grab some popcorn, and enjoy the adventure. Carboniferous here we come!

We seem to find the young of many baby animals cute, even animals far separated from us on the evolutionary tree, like birds. Clearly there is a limit since we don't find baby spiders or flies cute. But why should we, as mammals, find baby birds cute? We have no evolutionary imperative to protect the young of birds.

Hello to all. Photos from several trips of the past years. Probably, the age of these finds is the Kasimovian stage of the Carboniferous period (307 Ma). Despite the fact that many fragments of the crinoids lie on a large area, whole lilies were found only in a small "lens" about 7 * 7 meters in size. Finds from this lens are in the second part of the publication.

I’ve been told these blastoids appear to be Mississippian and I have some questions
SilurianSalamander posted a topic in Fossil ID
I’ve been told these blastoids appear to be Mississippian in age. That surprises me because the rocks in Dane county Wisconsin are late Cambrian - early Ordovician and the nearest Carboniferous rocks are a long ways away. I’ve done some research into the history of the buildings on the UW Madison campus where I find these fossils and they were supposedly quarried only a few miles from where they now lie. I was also told that blastoids didn’t appear until the Carboniferous. From a quick google search I got the impression that, while they massively diversified in the Carboniferous, they first appeared during the Ordovician. I’m just confused and curious as to how old these rocks are. They’re packed full of fossils and I often find tiny fossils that have eroded out of them and fallen to the ground to collect. attatched are the 2 or 3 blastoids and some of the other fossils I’ve found in these rocks. Any help as to what the age could be would be wonderful! also any IDs on some of the other fossils more specific than “gastropod” or “cephalopod” or “crinoid” are also appreciated. Thank you so much! Y’all are great.- 1 reply

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!

Carboniferous Welsh coal field teeth and lots more if I’m right
Ihopeitsnotarock posted a topic in Fossil ID
Hello everyone! if I could first stress I have been wrong about a lot of suspected finds so I’m hoping I’m not seeing things in the rock again!! I found these in a rubbish pile in work and assumed they could be coalfield fossils. If I’m wrong I apologise for wasting your time. There are a of these to get through If my suspicions are correct but I’ll start with 3 to see if im on the right track and refer to them as A,B, and C. I was told vertebrate fossils from the Carboniferous time period are rare so I wanted to make sure I haven’t got something that needs a more professional hand as some of them are very fragile and require stabilising and some TLC. I would also take any advice going please. Thank you so much in advance for any and all advice and opinions. subject A first 6 pics i believe to be a sharks tooth in a jaw (X2 I won’t insult you by hazarding a guess as to what species) subject B the next 6 pics i believe to be some form of icthyosaur tooth and there are loads more but just included 1 for now. subject c I believe to be part of an icthyosaur jaw. I am sorry if Ive wasted anyone’s time in the past and again if I have now but if vertebrate coal field fossils are important It’s worth the risk. There are around 2 bin bags full so I will happily make a donation if anyone is interested. let me know what you think please and I’l catalogue the lot after treating them. There are some larger pieces too which look very much like a skull. As I said I need help with them if they are fossils, and what to do about reporting them if required. hopefully they are not convenient water marks All the best- 6 replies

Hello dear fellow forum members, I just acquíred what I believe to be a moulted piece of Arthropleura armor. The Information I got was "carboniferous near Saarbrücken, Germany". Can I assume that the species is A. armata then? Best regards, J

Need some help with identifying these specimens. Are they a fossil or not? Carboniferous fossils from RI
veenasaur posted a topic in Fossil ID
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. They were a bit confused when they saw that we caught rocks. We had a laugh about it and spent some time walking along the train tracks before calling it a day which is something I would highly recommend. TIA- 9 replies

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.
