Fossil Amphibian/Reptile Footprint? Carboniferous of Rhode Island.
Dino2033 posted a topic in Fossil ID
I found this on a Beach on the west side of Narragansett Bay. I have found numerous plant fossils less than 2 miles away from here and I think that it has some potential to be a footprint. The impression goes deeper where there would be claws and it appears to have 3 toes. I would love to hear what others have to say. It looks very similar to others that I have seen from the Rhode Island Formation (middle to late Pennsylvanian). I will provide more pictures if necessary.

Hello, I found this rock in an ephemeral stream bed with what I think is an ammonite and crinoid head in the same rock. I'm somewhat familiar with the local geology and fossils but not 100% sure. It was found in Columbia MO in what should be part of the Osagean series of the Mississippian. Most common rocks in the area are limestone, chert, and dolostone; crinoids are extremely common. I'm a lot less confident on what I think is a mold of a crinoid head (second fossil pictured). I just hope it's not a chert nodule. Anyways I would love to hear other opinions to confirm this. Thanks!!!!

Another diffrent looking thing but is it another nautiloid?

Hi guys from flooded ireland, any idea what type of coral this is if it is coral

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.

Hi guys, just wondering is this a gonatite

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.

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!
