  1. Found this hiking yesterday

    Found this yesterday near Delaware Water Gap. At first I thought maybe a moth. However the shape and texture appears to be more feather like. Could this be from a small bird?
  2. Nittany Mineralogical Society Monthly Meeting

    http://www.nittanymineral.org/index.htm Geode Night with Jeff Smith The Geode Guy
  3. Can't remember what this is

    I know I've been told in the past what this is. I found this one today in a new (to me) spot - Old Port/Onandaga Formation, Devonian.
  4. Good start for the New Year

    Went out yesterday and found a few kind of neat things. Big plate of brachs, and what I think are Crinoid Calyx.
  5. Unknown Find

    Found here in Blair County PA - Tonoloway Formation, Devonian/Surilian. I'm not sure what this might by any ideas?
  6. A winter hunt

    In Late December, Minnesota is a land impossible to hunt fossils in. So when I took a trip to Ohio this Christmas, I was hoping mother nature would be kind to me and allow me to peak under a few rocks. While visiting my sister in NW Ohio, I convinced her to run up to Paulding with me to check out the Lafarge Quarry. Have seen postings about trilobites from there. We left Lima with no signs of snow on the ground. Two miles from our destination, the ground turned white, and snow was about 4 inches deep. Now I remember why I hated lake effect snow growing up in Ohio!! As long as we drove this far, we decided to travel on just to see the place. Fortunately, there had been a brisk wind that night and the tops of the rock piles were blown fairly clean of snow. Good enough for me. My sister thought I was nuts and remained in the vehicle. Here are the results of my short venture. Would love to visit this place in better conditions. I know how darctooth felt when he posted about his winter, snow covered excursion last week.
  7. Last Trip before Snow!

    Went out to one of my favorite roadside collecting spots shortly after I moved back to the Altoona, Blair County, PA, USA area. Cold, drizzly day but a bad day of rockhounding beats the best day of work! Here's a pic of a cleaned sample (approx. 3inx4in) of Crinoidal limestone (Shriver Formation - late Surilian/early Devonian). I've included a link {http://fcopg.org/wp-content/uploads/2014/06/68th2003.pdf } to a detailed description of the site. Hopefully this spring I'll be able to figure out where the trilobites are hiding.
  8. Help With ID Please

    Hi all, Would you be so kind as to help with an ID please. Found washed up on the shore of Lake Erie. Thanks! Pic 1 of 3
  9. ID help, Devonain, maybe coral?

    I'm new to the site, first post, great forum. My son and I found these in Devonian shale in Eastern PA. We also found Brachiopods. I thought maybe some type of coral? Scale is inches. Thanks for your help!
  10. Mt Pleasant Mills (PA) fossils

    These pictures are part of a large slab from the quarry at Mt. Pleasant Mills, PA. What is the fossil below the quarter in the first picture? Any idea what brachiopod is in the second pix? Thank you, Mike
  11. Seven Stars, Pa Fossils 10/13/16

    Found in Seven Stars, Pa. 1st pic is a Trilobite body, right? And could the 2nd pic be a rolled Trilobite? Thanks!
  12. This item was found in Lawrence County, PA at the edge of Slippery Rock Creek just below Alpha Pass (Falls). I've never found anything I deemed worthy of researching but this was interesting enough for me to want to find out. Any suggestions or insight would be appreciated, thanks!

  14. The Route Less Traveled

    We made a couple trips to Beltzville State Park in PA this past week. We had heard about brachiopods on the lake's beach from Robert Beard's Rockhounding Pennsylvania and New Jersey guide. The park is the site of dam and an artificial lake build by the Army Corps of Engineers with a stony bottom. A small, sandy beach sits along part of the lake with rocks get scattered from water action. The rest of the lake shore is red, orange, brown and gray mississippian sedimentary rock. I wasn't expecting much as it is a well-known spot in a state park that permits collecting and even provides ID sheets. Figured it would be pretty well picked-over. But, we went to investigate. You never know until you look, right? The first time out was a short, spur-of-the-moment trip with my husband to poke around while we waited for something we were planning to do later in the day. We walked over to the beach and found our first crinoid in about 5 minutes. Another hour of poking around revealed crinoid stems, brachiopods, bryozoans, corals, and bits of trilobites scattered along the shore for easy pickings. The water was crystal clear as deep as I dared wade in the sundress I'd worn for the planned, cleaner agenda for the day. I picked up a couple lying at my feet in the warm, still water. I decided then and there that it would be great fun to go snorkeling for fossils here. A week later, over Labor Day weekend, we returned with the kids. We walked as far towards the dam as the beach would allow, and discovered the real spot for fossil finds. Probably one pebble in four had something in it. Not all of it was worth taking home, but there was plenty to examine. My first glance down at the pebbles at land's end, I spotted a beautiful brachiopod. I picked it up and tossed it carefully to my daughter, parked a couple feet away and already holding a fistful. She caught it, admired it and tossed it back. I fumbled it, dropped it on the beach and lost it forever. Doh! So, if you see a lovely, round brachiopod on Beltzville's shore, think of me! There was more where that came from though, and we looked for a couple hours. When my daughter had had enough, I donned my swim suit and snorkel mask and went exploring in the area less traveled: under water! I only swam at a depth of arm's length. The boats and jet skis in the center of the lake that day stirred the water so that any deeper it was impossible to see the bottom. At this depth I could see the texture of the muck-coated rocks. The undersides of the rocks were clean, so turning the stones over carefully made for even better viewing. I turned up a pair of trilobites in only a few minutes! Unfortunately, that was about the only thing I found that way worth taking home. But, the fish were fun to watch. I expect that on a quieter day, when when the water is clearer, I may have better luck. All told, we brought home some nice shell impressions, crinoids, colony and solitary corals, bryozoans, and a couple that I did not recognize and were not on the sheet. The adventure will have to continue on the the ID forum. For now, though, here are a few scenes from the week:

  17. 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
  18. 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?

  23. Some gastropod specimens I collected in Western PA. in December in calcareous shale (Ames Limestone- Pennsylvanian) . Can you help with the genus IDs? Thanks.
  24. 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?
