  2. found this the other day looking for arrow heads along the edge of a field in a wash leading to the river. any one know if it's a fossil or am I just out in the sun to long. I appreciate and welcome all comments . have a great day
  3. Clearfield, Pa - Fossil or Not

    Found these rocks off route 80 in Clearfield, Pa. Lots of shale in Clearfield. 1st pic is a piece of shale I split open. The "fossil" is about the size of a golf ball, little bigger. 2nd pic is of 2 spherical pieces that are a red color vs the common slate colored shale. Sizes less than 2" in diameter. Fossils or not?

  8. Some gastropod specimens I collected in Western PA. in December in calcareous shale (Ames Limestone- Pennsylvanian) . Can you help with the genus IDs? Thanks.
  9. This summer I went on a trip to Red Hill, the famous freshwater vertebrate locality in Pennsylvania. The fossils found at the site are from the Duncannon Member of the Catskill formation, which is Famennian stage Devonian in age. I was lucky enough to find an area they had recently used a jackhammer to expose new fossils, in which I found loads of great fossils. I ended up with a lot of unidentified fossils, so I need some help with these. I think this is a fish bone: I'm pretty sure this is a megalichthyidid scale. I like how it is colored! Fish chunks. I don't know if these would be identifiable, but I would at least like to know what sort of fish they're from. Placoderm, maybe?
  10. From the album Carboniferous from PA.

    Lophophyllidium sp.? (rugose corals) Pennsylvanian Ames Limestone Mundys Corner, PA.
  11. Found these, my first Pennsylvanian Age marine fossils in calcareous shale in a road cut in western Pennsylvania on a recent trip. According to the Fossil Collecting in Pennsylvania guide, the formation is the Ames Limestone. Any help with IDs would be greatly appreciated. Thanks. 1.)
  12. U.Devonian Plants

    A plate of stems and branches from the "Red Hill" U.Devonian site near Hyner, Pennsylvania. Catskill formation I believe.
  13. This fossil was found in a stream in Huntingdon County, PA. I think the rock is a shale. I am not very familiar with geology or fossils so any identification help is greatly appreciated. My initial thinking (guessing) is that it is a coral or a fern-like plant. Thanks in advance!
  14. What happens When I get Bored

    My thanksgiving was a bit of a downer so I cheered myself with some fossil hunting in some of my old favorite spots. The trilobite and Shell casts are from a Devonian locality along Pa rt. 150, Howard, Centre County, PA. The gastropds are from a city park in Altoona. All were weathered out and surface collected.
  15. Swatara Gap State Park (1)

    It was a beautiful sunny day here in PA so I took advantage of it by cracking open some rocks I found earlier this year at Swatara Gap State Park. Pics 1 & 2. I'm thinking this is part of a Greenops. Both cast and mold shown. One pic taken in sunlight and one in shade. My question is, is this the head with eyes showing? It's at an angle where I can't quite figure it out.
  16. 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.
  17. 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!
  18. 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!
  19. A Field Trip To Saint Clair, Pa

    First of all, I would like to thank the Reading Anthracite Company for graciously allowing us access to their property near Saint Clair, PA. Our fossil hunt was a blast, and I would also like to thank the two Reading Anthracite employees who showed us how to get there, as well as directed us down the trail to the site itself. My family, as well as some other homeschooling friends, were allowed access to the site for our homeschool field trip. I handed out some pictures of ferns we might find, as well as some other general information about the Pennsylvanian period and PA coal mining, and then we walked down the trail to the site. We poked around some of the broken shale near the entrance, but it wasn't really that great. However, once we walked further into the site we started finding ferns like crazy. We found plenty of Alethopteris, a few Neuropteris pinnules and and a few other plants. We took some of the larger shale chunks from other peoples' old holes and split those, and we got some great ferns. My favorites are probably some of the nice Sphenophyllum stems and leaves I found! They weren't as common as ferns, but I love the look of all the little leaves arranged along the stem like that. We picked up some great ferns from the more weathered stone, but near the end of our fossil hunt I walked to the other end of the fossil site. I was annoyed that I had spent all my time closer to the entrance, because when I walked further in I found a lot better preserved ferns. I grabbed as many as I could carry, walked back to my backpack, but then we had to leave. We had an awesome fossil hunt, and we couldn't have asked for better weather. Hopefully, I taught my friends and family at least something about fossils from this trip It is getting dark now, but tomorrow I'll take some photos of the fossils. For now, here's a pic of the site: I am very glad that they allowed us access to the site. We were allowed access because it was an educational school field trip, but this gives me hope for other closed sites. Maybe, by setting an example of good fossil hunters, these sites may once again be opened. We can only hope!
  20. Wavellite On Gastropods

    Since I'm new I thought I'd share a pic of my prize find - Wavellite (hydrous aluminum phosphate = the green spiky balls) on a base of several gastropods from the Keyser Formation in Snyder County Pennsylvania.
  21. North-Eastern Pa Plant Fossil?

    Hi again Look at what my 6 year old son, a.k.a. fossil hunter found around our PA vacation house! When my husband gently split it, it revealed even more imprints inside. The third, smaller piece was found right next to the larger one. What do you think it is?
  22. Swatara State Park

    Hi...I am new to the group and new to fossil hunting so i can use all the help i can get! My daughter joined science olympiads this year...she has always had an interest in fossils so she competed in the fossil event (she even won a medal!) anyway this has lead to the whole family getting a new hobby. I am taking a road trip from NC to NJ in the next couple weeks. I thought to break up the trip maybe we could look for some fossils along the way. I drive I77 until just into VA then to I81 past harrisburg PA, then I78 into NJ. I found a place called swatara state park in PA...trilobites are my daughters new favorite thing in the world so i thought we could look around there. my questions are: Is it safe? It will be just my daughter and me as my husband cannot get away for the trip so is this a safe area to be in by ourselves? Is there anything left to find there? I saw that it is a .5 mile walk to the site but is there anything to find once we get there? Does anyone have any other suggestions of places to stop...hopefully not to far off the interstates? we went to aurora nc over christmas and brought back some dirt that she is constantly looking through so even something like that...the quality of the finds does not have to be the best, just fun for her to find something. thanks for the help!
  23. Trip To The Montour Preserve

    Yesterday I revisited the awesome Montour Preserve Fossil Pit! The pit is an old borrow pit the Preserve uses to dig gravel for trails and paths. The pit is open to collectors, and collecting is encouraged - a paved parking lot and a sign that says "Montour Fossil Pit" welcome any collectors to the area. When I first arrrived, I walked up and down the hill a little to look for surface finds. I've found some nice fossils using this method. When I was done with that, I searched for the spot I had been digging in last time I visited. I had been digging in a rather fossiliferous section of the hill. When I had found that, I used my chisel and hammer to pry out layers of the shale. It worked fairly well, but I wasn't getting that much shale out with that method. I had noticed some fault lines/fractures in the area I was digging, so I tried using them to my advantage. I hammered my chisel under a large section of shale, then I would use my hammer to lift it out. Using this method, I managed to clear a good section of the hillside. I got lots of trilobite heads, horn corals, brachiopods (huge ones!), and lots of other random bits of stuff. I think I even got a good section of a Greenops trilobite. I'll be air erasing most of these fossils before I post them, but here are a few teasers Trilobite (Eldredgeops rana) head in situ: Horn coral in situ: I had arrived at the pit around 6:00, so by the time I was leaving it was already getting dark: I'll post updates when I've prepped some of these fossils!
  24. Trilobite Fossils From Pennsylvania?

    I recently found this sample in a hill dug out for the construction of a new Walmart. I think the age of the rock is Silurian, but I need to get a more detailed map to double-check. It looks to me like there might be three pieces of trilobites on the rock. One bigger and one smaller at the center, and the other at the top left, kind of out of focus. I am thinking it is may be the anterior margin of the cephalon?
