  1. Carbondale PA

    Hello everyone! I am in the process of investigating the fossil site in Carbondale PA but can't seem to find the exact place where to go or any directions, there were some things I saw on the forum but they look like they are on private property. If anybody knows about it new insight would be greatly appreciated. Thank you.

  3. Bryozoan? Paleozoic/Mississippian?

    Can anyone help me indentify what these are? I’ve found them on a few of the rocks we’ve found, but haven’t been able to figure it out so far. They were found on a bluff in Boone County, MO, in the same area rife with the Crinoids we’ve been finding. I’m thinking from the Paleozoic/Mississippian Era? These are the clearest pictures I could get tonight but, if more are needed, I’m happy to take some in natural light tomorrow. Thanks in advance for your help!

  5. A Fossilized Thing

    Hi again! I’m totally stumped with this one. The rock is limestone, so its not the Billings formation. There is still some matrix on it, but most of the surface is exposed. It’s spherical and slightly faceted. Fossil pearl?

  8. Edestus teeth

    From the album Sharks and fish

    The shark relative is genus of eugenodontia holocephalid from the Carboniferous-Pennsylvanian age Anna shale formation, Carbondale group, found in different Illinois coal mines. I dont know(yet)which mine these were found in. This unidentified species is of the "vorax-serratus- crenulatus-heinrichi" or "E. heinrichi group", with the teeth being more of a standard triangular shape, as opposed to being thinner and pointed at a forward angle as in the "E. minor" group http://www.thefossilforum.com/applications/core/interface/file/attachment.php?id=501751

  11. Paleozoic selachians from the USA

    Johnson/2003Mitt.Mus.NaturkBerl., Geowiss. Reihe 6 (2003) 125-160 Nature of the beast (pun intended): taxonomical (systematic) Monograph " Dentitions of Barbclabomia (new genus, Chondrichthyes: Xenacanthiformes) from the Upper Palaeozoic of North America Gary D. Johnson' With 14 figures and 3 tables recommended, particularly for those interested in xenacanthids, orthacanthids, etc About 5 Mb Abstract Barbclabornia luedersensis (Berman, 1970) is defined on the basis of small (2 111117 high) isolated teeth that lack an intermediate cusp. It is known from the Lower Permian and possibly the Upper Pennsylvanian of North America. The two principal cusps are slightly curved orally, nearly parallel, and bear cristae mainly on their distal halves. They are cylindrical but become compressed proximally. The long axis of each cusp base is >45" to the labial margin of the tooth base. The base bears a prominent apical button in contact with the cusps; a central foramen is absent. Fewer than ten foramina occur on the aboral surface of the base, which bears a prominent concave basal tubercle. The shape of the base ranges from somewhat triangular to quadrangular. The cusps are composed of orthodentine covered by hypermineralized pallial dentine; the base is composed of orthodentine but may also contain trabecular dentine. Except for the possible occurrence of symphysial teeth, the dentition is homodont. Barbclabornia cf. B. luedersensis is stratigraphically highest in the known range of the genus and is restricted to the nearly lowermost part of the Clear Fork Group (Artinskian) of Texas. The teeth are similar to B. lztedersensis, but are more robust and have a quadrangular-shaped base. Barbclabornia was large, based on an undescribed palatoquadrate some 45 cm long. It was probably freshwater and is most closely related to Triodus. Key words: Chondrichthyans, Xenacanthiformes, Early Permian, North America.
  12. Hello, I have been a long time member of the fossil forum, but I have never posted before. I live in south Florida and I am planning on making a trip up to northwestern Georgia, northeastern Alabama, and southeastern Tennessee for two or three days and I was wondering if anyone had any suggestions on fossil hunting sites in the region. Any recommendations would be greatly appreciated.

  14. I found these fossils beneath a steel rail bridge in Maryland near the 4 locks of the C & O. You can find it. I think they may be Silurian, and are mostly brachiopods, including an adult brachiopod. Observe the fleshy muscle material in the center. Observe the 3 parasite wormy animals at the upper left. I think this was an old Brachiopod near death: It was infected with wormy parasites. Its muscle flesh was infected with a fungus that brought in sulfur in to react with the Iron in the water, creating pyrite which is yellow in the fossil. 400mya, the only yellow mineral was pyrite, Iron + Sulfur. This is how a senior paleozoic brachiopod dies. Observe. Out of respect, I am giving this animal the name Jesse, after my Grandfather. Jesse died of old age and we salute him.
  15. My family decided to take a few day trips to Delaware’s beaches this summer. We went to a few, and heeding some posts by @I_gotta_rock, I kept an eye out for fossils. I found a few, but three were good enough to show. No one knows which formation exactly they come from, only that they are Paleozoic. Sounds like a good Thesis to me. Anyway here we are, first a worn coral bit, kinda like a petosky stone. .7 inches

    Found this in Alexandria, TN (DeKalb Co.)

  18. There is a website that describes a controversial fossil found in 2003: http://www.abc.net.au/science/articles/2003/11/10/984724.htm Since it doesn't have a name at the time of publishing, I'm finding it difficult to find more information on it.
  19. Isotelus

    I found this last month on a visit to an abandoned limestone quarry near Naponee, Ontario. Though I am not very familiar with the Trilobites of this area, I believe it's an Isotelus. If I'm wrong with this identification, please tell me. It looks like there could be more of it underneath the sediment, and there is some matrix covering the pleura. This limestone is flaky and darker than any I have seen before. How would I go about prepping this? Though I've heard many people use sand, should I use something less abrasive, like baking soda? Thanks for the help.

  21. Triarthrus finds

    Hello again! This post will be about some beautifully preserved Triarthrus fossils (and my first complete Trilobite finds). Some of them even have the eyes preserved! I found these at a local train station, and the site of significant construction lately. I believe most of the to be E. eotoni, and the last one to be E. rougensis or spinosus. It may not be visible in the picture, but the last one has a streak of pyrite along the side of its cephalon / upper thorax. Could this be some kind of soft body tissue preservation, similar to those of the Beecher's Trilobite bed?

  23. Fossil ID

    This may or may not actually be a fossil. It is a cylindrical, shimmering white streak on the Shale. It is only about an inch long. This may just be another mineral inclusion, or some discoloured sediment. Any help with identifying this would be appreciated!
  24. Ordovician Road Cut

    Yesterday, I was lucky enough to attend a very special field trip with the Eastern Ontario Natural History Society to a massive road cut in Ontario. The rock exposed was Ordovician aged limestone, and it produced some amazing fossils. I might need some id help with some of these. The giant cephalopod was by far the best thing I found! 1. Giant Cephalopod (with hand for scale) Camerocerad or Endoceras? 2. Crinoid stems, bryozoans and Gastropod 3. Partial trilobite pygidia
