    Some really cool fossils from my land!

    My collection of some really cool fossils on the land most of the fossils I have in my collection are bought so it’s always nice to find something actually in the field. Now my main goal with this post is to try to identify the trilobite I found today although it only has the head piece, it clearly shows the eye and part of the gabella. The horn coral which are the sort of conical fossils should help identify the age of the rocks. if anyone else can give an ID on the rest of the fossils that would help thanks. By the way these were all found in Dane County, Wisconsin. (PS) I have no clue what

    UK Convex Spherical Structure (marine)

    Heya! This is a spherical convex structure found in the South of the England. Unfortunately, as I found it when I was very little, I cannot seem to recall the exact location, and, thus, the age. Originally, as a child, I crudely assumed it to be a mushroom... Ah, the wonders of child's minds... More recently, I conducted a study upon it, and, due to the septa and mouth-like crystalline structure at the top, I identified it as a polyp cup of a Rugosa coral. However, I am still unsure as to what it is. Any input would be greatly appreciated, cheers!
  4. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    This young, possibly ephebic, corallite had a very deep attachment area on bottom. This rapid upward growth may have occurred in response to—you guessed it: Sinking in the mud.
  5. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    The next few images will show some of the many growth forms of Gymnophyllum wardi, a solitary rugose button coral. G. wardi is the only known species of the genus. It is locally common in the Middle Pennsylvanian (Westphalian) Wewoka Formation in Okmulgee County Oklahoma. Fossils of the species also occur in the lower part of the Labette Shale in Rogers County Oklahoma. The tiny corallite in this image displays many characteristics of the early, neanic, stage of growth, including crooked septa and a deep central pit.
  6. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    This tiny Gymnophyllum wardi corallite shows neanic characteristics, including long septa that extend from the center of the calyx to the periphery. Also, at the center of the bottom side, you can see the small area where the corallite attached to the mud in shallow, calm seas where these corals are believed to have lived.
  7. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    This Gymnophyllum wardi corallite exhibits characteristics associated with the ephebic (maturing, or nearly mature) stage of growth. For instance, note the beginnings of a central dome on top.
  8. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    The Gymnophyllum wardi corallite in this photo shows various ephebic characteristics, such as the insertion of minor septa between the central dome and the periphery.
  9. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    This likely ephebic corallite of Gymnophyllum wardi displays the notched septal ends that are often seen in this species.
  10. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    This specimen of Gymnophyllum wardi appears to be mature, having a broad, smooth central dome on top and fused septa that are visible mainly near the periphery. This species grew by spreading horizontally, a process that often left conspicuous growth lines on the bottom surface of the corallite.
  11. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    This mature Gymnophyllum wardi corallite looks like a pie crust due to the prominent central dome, fused septal ends, and the three apparent wounds on top. Fusing of the septa served to increase the surface area of the base. This may have kept corallites from sinking in soft mud.
  12. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    Some mature specimens of Gymnophyllum wardi had low, flat tops. Again, note the fusing of some (but not all) of the septa near the periphery. Also see the prominent growth lines on the bottom surface.
  13. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    The growth lines on the bottom surface of this mature specimen give the appearance of several corallites stacked one upon the other. This pattern is often seen in Gymnophyllum wardi and may indicate sequences of regenerative events.
  14. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    This mature specimen of Gymnophyllum wardi has very thick growth lines on the bottom surface.
  15. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    Gymnophyllum wardi corallites often display swelling at the ends of the septa, a characteristic that may have helped prevent sinking in soft mud.
  16. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    Some corallites of Gymnophyllum wardi exhibit partial walls at the periphery of the calyx. Again, this may have been an adaptation to limit sinking in mud.
  17. From the album: Pennsylvanian Fossils of Northeast Oklahoma

    This specimen of Gymnophyllum wardi shows evidence of regeneration (the appearance of one corallite growing atop another). The angle of regeneration suggests the young corallite may have become tilted before sprouting a new top in a more upright orientation. Although Gymnophyllum wardi has been extinct for millions of years, we can imagine their appearance in life based on pictures we can see by googling the term “button coral”. If you would like to learn more about Gymnophyllum wardi, I recommend two excellent sources that can be downloaded as pdf files from Google Scholar, as f

    Rugose Coral #1

    Devonian coral

    Ahoi, I have been lucky to find some real fossils out in nature today! That is not as often the case for me as for some of you lucky rockhounds, I often have to resort to hunting online or building replicas. But this time I went out and found something. There is a famous devonian reef preserved in grauwacke some 50 kilometers from where I live. the Quarry itself is protected, but there are some piles of overburden rock in the vicinity. Here is a sample of what I found: To the right (1) I think is a badly preserved solitary rugose "horn"coral. To the left (5) a "
  20. I went on a bit of an unusual fossil hunt this morning--in my office closet. I'm getting things packed up for a move next month to Gainesville, FL. We're moving up there from South Florida because I've had my fill of hurricanes (and year-round yardwork). In Gainesville I'll be able to volunteer more with the FLMNH. So I'm slowly repositioning the contents of my house into a growing stack of moving boxes. I got to the bottom corner of my office closet today and found a box that had some childhood memories in them. No favorite stuffed animals, no catcher's mitt and baseball, no che

    Rugose coral?

    Is this a rugose coral?

    Rugosa from Trout River Formation upper Devonian. 5cm in length.
  24. Hi everyone, looking for some help in identifying some corals from the two beds in the Scottish Lower Limestone Formation, the Hurlet Limestone and the Blackhall Limestone. Both are Visean, Brigantian in age. Any help much appreciated! @TqB I'm hoping you might recognise them right away First these smaller specimens, all are from various outcrops across Scotland of the Blackhall Limestone. The largest 34mm long. Another from the Blackhall Limestone, this ones a bit larger at 85mm. Another from the slightly older Hurlet Limestone this time, 5
