  1. Finally ? ? A Trilobite ?

    Could this be my first trilobite ? It was found within a foot of the coral I just posted. Looks like faint indications of several (pieces) in the pics. Go ahead .... make my day.
  2. Shell ridges or animal scales ?

    Hi folks, another discovery in my garden. I haven't seen this size or type of segmented surface before. It doesn't really look like a shell as it has a wavy contour that I hope you can see in the pics. Thanks,
  3. Milford PA Mahantango

    These from a natural outcrop and a roadcut in the middle Mahantango near Milford PA. Cheers, Gordon Bryozoa? Crinoid bit? Diplueura dekayi, looks like Gastropod Tropidoleptus carinatus, looks like
  4. Mahantango, Pennsylvania Coral? Sponge?

    Found today by a friend in PA. Someone suggested it might be a sponge but I can't find any images that resemble it. Thanks, and as always, much appreciated.
  5. MF 9

    From the album WhodamanHD's Fossil collection.

    Crinoids
  6. MF 9

    From the album WhodamanHD's Fossil collection.

    Lots of crinoids and some shells.
  7. MF 8

    From the album WhodamanHD's Fossil collection.

    Large burrow, most likely polychaete worm. Collected outside McCoys ferry. Other than that not much, a few shells. The obverse is below.
  8. MF 7

    From the album WhodamanHD's Fossil collection.

    A hash of many species of brachiopods and crinoid s, no idea what most are. Found outside of McCoys ferry. On the back is a worm burrow, probably polychaete, and another possible one shaped like a chicken footprint, even after an ID thread we couldn't come up with a better explanation. Back is pictured below.
  9. Possible Devonian plant

    Found this in some pants, presumably from a trip to Hancock for fossil collecting. At first I thought it was a common burrow, but then I noticed a carbonized streak, could it be a plant? Mahantango formation, givetian.
  10. Zoophycos

    From the album WhodamanHD's Fossil collection.

    A large zoophycos outside of McCoys ferry. To my knowledge it's still there. It's not really in my collection because I didn't have the tools to remove it at the time but since it's my icon I will consider it part of my collection.
  11. Mahantango brachiopod ID

    So as I am new to this whole formation and it's species, so I need some help again. Does any one know the species or genus? This is a brachiopod, the largest species I have yet come across in the Mahantango outcrop outside of McCoys ferry. I have found a few of these, only one larger than this but unfortunately it was broken. In big pool, MD I once came across a rock face with around 10 eroding out of the cliff, I didn't have the tools to collect them however. I can try to provide any other useful information needed to ID.
  12. MF6

    From the album WhodamanHD's Fossil collection.

    Huge plate of crinoid presumably a Created by crinoid "reef" being destroyed in a storm.
  13. MF5

    From the album WhodamanHD's Fossil collection.

    Brachiopods.
  14. MF4

    From the album WhodamanHD's Fossil collection.

    Chonetes and crinoids.

    From the album WhodamanHD's Fossil collection.

    Chonetes and a crinoid.
  16. MF1

    From the album WhodamanHD's Fossil collection.

    Two large crinoid stalks, 4 tentaculites, multiple brachiopods.
  17. MF2

    From the album WhodamanHD's Fossil collection.

    Posibile trilobite fragment found by myself near McCoys ferry, Maryland.
  18. What is this?

    Hello everybody, So a few months ago outside of McCoys ferry, the first time I had done so. The ultimate prize was a trilobite since they are quite rare in this outcrop. After some intense searching I found what I thought to be a trilobite fragment, however now I'm not to sure. Is this a trilobite or a horn coral or something else?By the way this is Mahantango shale of the givetian epoch of the mid-Devonian period. I tried to do some amatuer prep work with a scribe to see if any other fragments were hidden within the matrix but there was not. Let me know what you guys think.
  19. Mahantango rectangular fossil ID

    Hello everyone, I was doing some collecting in the Mahantango formation of western Maryland, which you might know is Givetian in age, and I started finding these strange rectangles or bars with smooth walls. They are definitely fossils but reveal no pattern when viewed under magnification. They differ in size and width. Like most of the fossils, sometimes they have yellow or orange residue upon them. The site itself is grey shale and I assume it to be deep water from from a large Zoophycos in the rock face. I have no idea what these could be, although I have ventured a few guesses, such as graptolite, strange crinoids, bryzoans, plant fronds (some plants have been found here by others), maybe even sections of eurypterids. One I found has a strange theropod shape (positive and negative below), although this could be a different phenomenon. Here's some pictures and tell me what you all come up with!
  20. Mystery circular, ridge and groove fossil. This fossil is a slightly oblong to circular fossil ranging from 5mm in diameter to 12mm in diameter. It is composed of a series of ridges and grooves radiating from the center to the edges. At the center, the ridges do not connect to a central point (at least in no example that I’ve found). Very few examples show the central feature, but in the best preserved of them, which appears to be complete (see photo) there is very small central circular depression and the radial ridges and groves terminate at the rim of the depression. That example may also show remnants of a stem fragment or other object in the central depression, but it is not clear. From the better preserved specimens it is easy to see that the fossils in question are three dimensional, rising from flat rock surface at the edge to the raised central depression. However, most examples are missing the top third or half of the specimen (see second photo). In those cases, the fossil presents as a narrow ring of grooves and ridges with a large flat top and no obvious internal structure. The number of ridges varies from 35 or so to over 60, but they are hard to count because what starts out as a single ridge at the top (near the depression) sometimes branches into 2 ridges at the bottom near the edge. All of the specimens that I’ve found seem to be flat and secure to the rock on the bottom. I haven’t tried to separate it from the rock to see if there are any details underneath. These are common fossils at a site in Hedgesville, WV. Jasper Burns, in his book Fossil Collecting in the Mid-Atlantic States, dates these rocks to the Devonian, specifically the Mahantango formation which I understand was laid down about 392 and 385mya. In the same rocks, I’ve found plentiful shell fossils of numerous species that I haven’t identified yet, including, in one instance, a very small shell fossil trace embedded on the mystery fossil above. Burns’s book doesn’t appear to discuss this fossil in his chapter on the same locality, and I haven’t had any success even using Index Fossils of North America. From some photos online, my best guess is that it may be a crinoid segment, although they all seem to lay perfectly flat, and I wonder if it may be a holdfast of some sort. Any help would be appreciated. Thanks, Alex
  21. Mahantango Trilobite Cephalon?

    Is this a Phacops or Dipleura cephalon? Or another type of trilobite? Am I looking at it right by calling the crease on the lower part it's "lip"? I included the top and back side. It seems out of proportion when I think about where the eyes should be. Maybe someone could take a guess at how wide this one would be if it were whole? As always, thank you for sharing your knowledge! Found in Seven Stars, Pa.
  22. Mahantango Fossil ID - Crystallized Coral?

    I spent today in Seven Stars with my 2 (crazy & wonderful) sisters collecting fossils. (Middleburg, Pa) This is the most unique thing we found. It just doesn't seem to fit in with all the other fossils we have found there. It appears to be a piece of plant life by the way it branches out into nodes. (?) It's really hard to tell in the pics but all of the insides are crystallized in a smokey colored quartz/crystals. Of course I forgot to put a coin beside it when I snapped the pics, sorry. It is about 1" long by about 3/4" wide. Any ideas?
  23. Mahantango Fossil ID (5)

    More fossil ID's please! Found at Seven Stars location. Devonian I presume. 1 & 2 are of some sort of ball or spherical rock/fossil? Front & back. More to come.
  24. Mahantango Fossil ID (4)

    Found at Seven Stars, Pa location. Pics show top view with rippled circular area, bottom/looking into textured area (it almost looks like a smooth shell was lodged into the center) and last pic of the back of the matrix.(the lighter area on back is where I was trying to chip away but then decided to leave well enough alone) Size is 1" in diameter. TIA for your help!
  25. Mahantango Fossil ID (3)

    Found at Seven Stars, Pa location. Both fossil face & matrix back shown. Size is 2 1/4" long x 1 1/2" wide. TIA for your help!
