  1. Unknown coral? Likely Devonian

    This one has had me stumped since 1985. Found it while I was supposed to be harvesting potatoes. Not sure of exact member as was kicked up by the plow. Collected October 1985 by yours truly. Erie County Pennsylvania Summit Township Upper Devonian - Chadakoin Formation (?) Found as is...red is from a wax marking crayon I didn’t realize I had in my pocket when I brought it to work today. Detail photos of conspecifics included.
  2. Dear Members, three years ago I found a small fossil in the Ames Limestone Formation (Pennsylvanian in age) exposed in Frick Park, Pittsburgh, PA. The Ames Limestone preserves a rich assemblage of marine invertebrate fossils (crinoids, corals, etc.). On the other hand vertebrates are much more rare (as far as I know). Originally only the tip was exposed, then I had a fossil preparator work on it, so that the whole specimen is now visible. Close up of the tip at 20X It is definetely fragmentary, but I don't know what it is. I would exclude a fish/shark tooth, because it is too flattened. I think it might be a fish scale, but I really don't know. Do you have any idea? Thank you, Fabio
  3. Rugose Coral? New species?

    Here's some of the odd specimens I've collected and cant identify...please help me, its maddening to have so many of the same thing yet can not ID it...14+yes and counting

  5. Triassic Wing Ribs or Sedimentary Trace?

    Found this piece on a walk near a Triassic outcrop in Pennsylvania, has a pretty exact visual similiarity to the wing rib of a Triassic reptile but is likely just some form of sedimentary trace. It would be great to get some more opinions on this piece to see if its worth holding onto or I would label it to be definitely sedimentary and rid of it, which I feel is the case.
  6. Hi all, I’m not sure if I’ve posted this find before, but I figured I would anyway because I believe it warrants it’s own thread. I found this find a few years back at one of the localities I most consistently collect at, which is a shaly exposure of the Connelsville Sandstone in western PA. It usually preserves plants quite well, and was described by W.C. Darrah back in the 60s. It has also produced some very early examples of Walchia, an early conifer. However, it is not well known for vertebrate fossils, as sandstones don’t seem to be the preferred type of rock where vertebrates are found in the area. If you’ve seen my other posts you’ve probably realized that most of the time vertebrate fossils are restricted to shales and limestones, often closely related to coals. And in the shales especially, concentrations of material are usually lag deposits and do not represent associated remains. Here I have something different. Its a small jumble of bones, with no diagnostic features whatsoever. However I can rule out actinopterygian material because it lacks the thick shiny scales so characteristic of this group. I’m almost certain it’s not tetrapod material as (1) they are incredibly rare and (2) the ribs seem to be too thin. I’m also fairly confident that it represents a single individual as the bones are locally concentrated and I’ve never seen them before from this locality. I’ve found bones like these before in other more characteristic deposits, although they are never articulated. I’m relatively sure that they come from some sort of sarcopterygian, possibly a dipnoan or coelacanth. I would be very happy if anyone could shed some light on the general grouping of this fossil. If not, then just appreciate it as a random jumble of bones from a not very often seen locality. As always, stratigraphy: Connelsville sandstone Casselman Formation Conemaugh Group And age: Late Pennsylvanian (Stephanian/Missourian ~302 MYA)
  7. My Fossil Collection

    I've been collecting fossils since 2011 and have since acquired a substantial number of specimens. The focus of my collection is mostly on fossils from the United States, including from my home state of Pennsylvania. To start things off, I'll show the highlights of my collection of fossils from the Kinzers formation, which runs through Lancaster and York counties in Pennsylvania, not far from where I live. It's known for trilobite and echinoderm fossils and dates back to 512ma, older than the Burgess Shale. I remember seeing trilobites from the Kinzers at a local museum when I was younger, which inspired my interest. Olenellus thompsoni is the most common trilobite of the Kinzers. These are from York (top three) and the Fruitville quarry in Lancaster (bottom). Wanneria walcottana is the other common trilobite of the Kinzer's formation. Both pictured were found in Lancaster. From near Millersville (top) and Brubaker's quarry (bottom). Mesonacis is a very rare trilobite in the Kinzers Formation, found only at Brubaker's quarry. Camptostroma roddyi is the echinoderm that the Kinzers is most known for. The lower one is a mortality plate of ten of them, and some have feeding appendages preserved. Both are from York. This is a very rare species from York. I believe it's some sort of Helicoplacoid. Salterella was an enigmatic animal of an extinct phylum that appears in the Kinzers as well. A plant, also from York: Finally, some sponges from the Donnerville quarry in Lancaster. Both sponges are on opposite sides of the same plate.
  8. Good afternoon, I have submitted photos of this fossil to multiple local groups in hopes of a possible identification to no avail, therefore I have turned to this forum and home to figure this out! I hope it to be a calamite cone fossil but I have been wrong before, so I am asking for a second opinion. Thank you very much! Important information: This fossil was pulled off a shale cliff that is abundant in calamite and fern fossils. The cliff is located near Carnegie, Pennsylvania (Western PA). The specific fossil has both calamite and ferns on the reverse side. Edit 1: The size is about 1.5 inches (3.81 cm). Information that is possibly helpful but may not be: The cliff has a few layers of coal and black colored shale, while the majority of the cliff is a grey colored shale. This rock was pulled off just above a black shale line.
  9. Saturday dawned a bit chilly, but the sun peeped out from lingering clouds to brighten a stellar day of fossil prospecting in the Ordovician bedrock of central Pennsylvania. We strolled along the limestone ground, like beachcombers peering in shallow shore waters, when my relatively newbie friend exclaimed, "That looks like a starfish!" Bingo...Indeed it was an Asteroidea. I'm guessing it's genus Urasterella, and I wonder how rare is this find. The specimen's longest ray is 1.75 inches (4.45 cm). Photos are the rock slab and a closeup of the mostly complete starfish, as found.
  10. My family and I are on short end of season camping trip in Southeastern Pennsylvania and decided to head over to Gettysburg. These have probably been covered here before but I got some pictures of the famous Dinosaur Footprints on the Bridge! My son loved it (I’m gonna pretend more than me ). Anyone know of anywhere I can go searching for some fossils while I’m in the area that’s around the Gettysburg area??
  11. Pennsylvanian Fossil?

    I found this near a small creek in the Casselman Formation right outside of Pittsburgh. It was originally covered in some sort of black matrix, most of which I scraped off. It really looks like a piece of bone (maybe a tibia or a radius?) to me, but I might just be crazy. Thanks!
  12. Stigmaria

    From the album Plants of the Lewellyn Formation

    Root of a Lepidodendron (scale tree) with rootlets radiating out at right angles along both sides. The white powder highlighting the imprint is iron oxide, most likely pyrophyllite, left over from the actual plant. Lewellyn Formation (same formation that runs through St. Claire) Lackawanna County, PA Pennsylvanian age
  13. October Ghost Town Hunting

    Last fall, I drove out to Centralia, PA, the famous burning town. The coal vein below the town caught fire, creating random sinkholes filled with toxic gasses. The town was abandoned. The buildings were bulldozed. Only the most foolish set foot in the town limits. Today, however, the fires have mostly followed the coal vein out of town. I was out once in September, just to check the lay of the place, then returned in October to find fresh "No Trespassing" signs. Darn! Six weeks ago, I got a report that the signs were down. The person making the report said they double-checked with the locals in the next town and were told that yes, it was fine to go fossil hunting out there. So, today my hubby and I went to investigate. The signs were indeed own, replaced two with Keystone State logos. One banned motor vehicles. The other announced that the property owner agreed to allow game hunting but a permit was required. That was it. In we went. The fossil outcrop is part of the Lewellyn Formation, which also runs through the now-closed St. Claire site. Lepidodendron, calamites and cordaites cover almost every inch of the shale. The impressions are coated with shiny, black graphite, white pyrophyllite and kaolinite, plus some bits of other colored iron oxides and even some shiny pyrite. If you go, be warned that the slope is steep and treacherous. I used rock climbing gear so that the scree didn't slide out from under me, sending me sliding fifty feet or more down the hill. The woods at the base are navigable, if a bit tangled in spots, and are littered with everything that weathered off of the slope, including occasional large hash plates.
  14. I enjoyed a productive weekend hunting petrified wood in the Triassic age, approximately 210 mya, Newark Supergroup of Pennsylvania. The first 2 photos show a single specimen's 2 sides, illustrating profuse checking in the wood, and a likely rotten dead limb knot at top. Specimen weighs 19 pounds.
  15. Unknown something

    Really not sure what I have here, it definitely stands out from the surrounding matrix. I found this chunk at the Rockville Quarry site north of Harrisburg PA. There are some brachiopods in the surrounding matrix.
  16. Fossil imprint

    Hi! First time posting here. Curious about a rock that looks like a fossil imprint. Can anyone help me identify what it could be an imprint of? Found many years ago in North East, Pa. thanks in advance for any help!!
  17. Fossil hunted with my college roommate today towards the deer lake region. Here is about 1/2 of my haul, will be excited to clean them and remove some matrix eventually and uncover them more!
  18. Central PA Tips?

    I'm currently planning out some sites to check out in the Central PA area... I'm trying to stay within 1-1.5 hours of Harrisburg if possible. Right now I am considering trying my luck at exploring the Rockville Quarry or what was left of it, as well as just taking a shot in the dark and checking out a few streams in the area. My first official fossil hunt was last Friday (Aug 28) at the Swatara fossil pit. Found a few shells and what I believe to be a partial trilobite exoskeleton or imprint. Definitely going to check that site out again though. Does anyone have any tips/locations for the Central PA area? Right now my holy grail is a complete trilobite but I'm so new to the game that I get excited at any remnant of a previous life.
  19. A few Mahantango finds

    I recently visited a few formations around PA, The Montour preserve pit happened to be on the way and I stopped by, The location was quite picked over as @historianmichael told me, but we did manage to get some nice finds. I will post a trip report later but for now, I want to get some IDs for some of my finds from here and another location. First, is what I thought in the field was a brachiopod but upon closer inspection, I realized that this is probably my first pteriomorph mollusk which is very exciting for me, my question is: Which? I looked through Linsley and multiple look similar, I just don't have enough experience with these to really be able to tell.
  20. Fossil Wood in Southeastern PA?

    Hello again Fossil Forum, Last week I posted a few pictures of what I thought might be fossil wood that I found on my property in Southeastern PA (Montgomery County, just over the Philadelphia County line). It seemed that it was possible that my rocks were fossils, but also maybe not... One helpful user suggested that I might polish some of the ends (hopefully crossections) of a few pieces. So below and in the next few replies I will post some pictures of a few pieces, for the polished parts I used a cabbing machine. I live at the bottom of a relatively steep hill and these pieces were all found within about 50ft of each other. If there seems to be some variety, that is in keeping with what I found after consulting several geological maps of my area: my property appears to lie at the precise intersection of precambrian, lower paleozoic, and cambrian regions and includes both sedimentary and metamorphic rocks. If not fossil wood, possibly stromatolites? ...or just more interesting rocks?? For discussion purposes I'll number the pieces and put them in separate replies. Thank you again for any thoughts, information, and opinions!
  21. Is this a fern?

    Found this back in April on a mountain, still amazed by the detail. Not sure what species it is, the area is mostly Carboniferous.
  22. I found these, endocast impressions of dorsal shields of the jawless fish Americaspis americana, in the Silurian of Pennsylvania. There are 2 1/3 dorsal shields shown. A complete shield measures approximately 2.4 x 1.0 inches (6.10 x 2.54 cm).
  23. petrified wood?

    Hello Fossil Forum! I love rocks and rock hounding (but very amateur) and I look at the ground wherever I go. I picked up these rocks from a few locations in Montgomery County, Pennsylvania. Most collected over the past year, found in hillsides (not streams). I think that they all look somewhat like petrified wood and was curious if anyone else has found similar samples from this area and/or knows anything at all about them. Thank you in advance for any thoughts, information, and opinions!
  24. 19cm long tooth?

    I inherited my grandfather's modest fossil collection, and in it was this 8 cm wide by 19cm long fossil that I need help identifying. It is pointed at one end, has external ridges and an internal hollow at the other--features that look tooth-like to me, but I'm a newbie at this. Unfortunately I have no information on location of discovery or likely age. My hope is that fossils like this are common enough that one of the more educated and experienced here will recognize it right away. I'd be grateful even for best guesses that help me direct further research.
