  1. Seed Cone

    From the album Plants of the Lewellyn Formation

    Early Conifer Fruit/Seed Body about 4" long Pennsylvanian Age (308-300 MY) Lewellyn Formation Columbia County, PA The impression is coated in white iron oxide left from original plant material during fossilization.
  2. Inspired by a post last week by @I_gotta_rock, I decided to take a bit of an impromptu trek out to Centralia to add some of the famous white fern plates of the Lewellyn formation to my collection. I say impromptu because I was told I needed some pretty good rock climbing gear to be safe at the site, I ordered some pretty nice rock climbing gear too, still decided to go take a peek before everything arrived leading to one heck of an adventure that still has me smiling from ear to ear. We got our stuff ready to head out bright and early when I immediately hit my first snag, last week's adventure to the C&D canal left me with an absolutely lovely set of scars above my ankles from the thickets of exactly-the-height-of-my-ankles thorn burrs that had overgrown the spoil piles. Given that the scars were still healing, I decided to forego my normal high cuff desert boots that would surely rub against them all day for my trusty pair of low cut boat shoes. I'm pretty good on my feet right it'll be just fine yep. Off we went, excited to check out the mystery 'burning town' and the fossils said to be found there, a decent bit into our drive down 61 I noticed a billboard for 'Deer Lake Pub & Restaurant'. I thought to myself "wait didn't some guy find trilobites behind some bar in Deer Lake?" oh he sure did, queue "Hey hun, wanna have dinner at that nice little pub on the way back? maybe check out the rocks around the random excavator they have in the parking lot?". I got the go-ahead and gave a silent fist pump, two birds with one stone! We had barely any trouble finding the site out in Centralia, thanks to excellent directions from @I_gotta_rock and an encounter with a man and woman on the path out as we were headed in. He held a gigantic slab of black shale as triumphantly as any athlete with a trophy and she followed behind hefting a yellow 5-gallon bucket. Few words were exchanged but I do hope they browse this forum. Not too shortly after we arrived at the slope of scree and made our way to the top to survey the site. The view was breathtaking, overlying the subtle thought of "hold up it didn't look this steep in her photos" - though an adventure we came for an adventure we were going to have. We spent the afternoon slipping and sliding across the scree, maintaining a low center of gravity (butt-scooting) as we clambered up and down the slope. To say the site was plentiful would be an understatement, we were literally walking over layers of fossils. I decided to focus primarily on collecting small/medium sized specimens as the shale was quite fragile and dragging a 15lb chunk of rock up that slope would've brought me too close to my own mortality for comfort. We wrapped up our time in Centralia after collecting our fill and emptying my shoes of scree for the 10th time, leaving enough time for a short drive down 61 to Deer Lake. As the sun was setting we pulled into the parking lot at Deer Lake Pub & Restaurant, parking a stone's throw away from a freshly made cut into the Mahantango beneath a nicely perched excavator. We took a short look around the site, primarily shale/scree with plenty of good looking rocks to hit with a pick. Hoping for a trilobite we lost the race against the sun going down but did make out with a small bounty of brachiopods and a crinoid stem. All told, I couldn't be happier with the day's haul having just finished basic prep work at 10PM. I'd say the finds of the day were a mystery specimen from Centralia that i'm hoping is some sort of seed, a clean/closed clam like brachipod from Deer Lake and numerous well defined small to medium sized fern plates.

  3. I found this nice specimen while hunting for 'white fern' plates out in Centralia, PA. Based off of the size, shape and definition, I'm curious if its a seed of some sort? I left the seed un-prepped with the white silicate mix still present, would love help with an ID
  4. Trigonocarpus?

    I recently collected this plate out of a block of shale full of Alethopteris fronds from the spoils of a coal mine in Pennsylvania. You can see some of the Alethopteris on this piece. My initial impression is that these are seeds, with Trigonocarpus serving as the kinda catch-all for Pennsylvanian fern seeds. However, I have never seen an example of Trigonocarpus that has these markings. Both of these fossils have little, golf ball-like dents on them. The fossils measure 4cm and 2.5cm respectively. Has anyone seen something like this before? Do these markings mean that these are something different than Trigonocarpus? Any help is greatly appreciated. Thanks!
  5. Pennsylvanian Lepidodendron Mystery

    I recently collected this piece with these two articulated fossils at an exposure of the Llewellyn Formation in Pennsylvania. They are respectively 14cm and 16cm in length. Based on an image in a book I initially thought they were Lepidostrobus (the cone of Lepidodendron) but now I am having my doubts. Examples of Lepidostrobus that I have seen on the Internet include the scales that come off the cone and these fossils clearly do not have these scales. On the other hand, these fossils have the typical diamond pattern that is characteristic of the bark of Lepidodendron, leading me to believe that these are examples of its branches. Yet they don't really look very branch-like with how thin they are and how much they bend. Does anyone know what these could be? Any help would be greatly appreciated.
  6. Mahantango formation clam or armored fish?

    Could it be Zascinaspis heensi or just a clam?
  7. Hello everyone, I am currently looking for any PDFs that list the Palaeozoic fossils of the North Eastern United States, I am especially interested in the Devonian of New York and Pennsylvania as this is the most familiar to me. I have had the Linsley PDF for a while now and it has been very helpful but it does not go into much detail about echinoderms, corals, or non-brachiopod lophophorates like bryozoans found in NY which I would like to learn more about. Thank you for any help, Misha
  8. PA Ordovician Unknowns - ID Help

    I recently collected these three fossils on a trip to the Salona Formation in Pennsylvania. I was able to identify everything I found except these three. Any help would be greatly appreciated. #1 - initial thoughts were Cryptolithus genal spine but it seems very large for Cryptolithus and I did not immediately see the pits that are normally associated with Cryptolithus #2- perhaps some type of sea plant? #3- no idea. It reminds me a little bit of Tentaculites. It measures about 1 cm in length.
  9. PA Ordovician Starfish

    For Father's Day Weekend my dad and I drove into Pennsylvania yesterday to collect Ordovician fossils at a location I read about with access to the Salona Formation. With rain in the forecast I was a little worried the trip would be a total wash. Instead, we experienced beating sun, and, having left our hats at home, we quickly began to overheat. My dad also found two snakes while overturning some large rocks. To say the least my dad was ready to leave after an hour. Luckily I was able to convince him that if he wanted to stop he should at least let me poke around for another 30 minutes. While I was poking around my dad decided that it would be safer for him to remove and examine new material than to work in the talus. We worked for another hour before calling it a day. When we got home I went to work washing off the many hash plates my dad exposed while removing new material. The plates were covered in a fine layer of dust so it was incredible to see what they fully held after washing them off. As I was washing one plate I had to stop myself in the middle. I could not believe my eyes. In the bottom corner of one plate there was a rather familiar shape that I was not expecting to see. I immediately knew what it had to be. In all of the literature I have seen no mention of starfish fossils being found at this site. Given that my dad was ready to leave after an hour I consider this find even more lucky. Although I did not have anything to go on, I believe that the starfish is Promopalaester bellulus. It certainly made for an exciting and memorable Father's Day Weekend! Here are some of our other exciting finds: Hash Plates with Bits of Cryptolithus Ventral Ceraurus Cephalon Pygidial Spine of Ceraurus Ventral Isotelus Thorax
  10. Hello, I was wondering where to find PA fern fossils. I've heard of both the Carbondale and St. Clair sites, but I've read these are both closed to collecting. Where else could I find some decent fern fossils? I am from NJ (so this would have to be on the East/Central parts of PA for a day trip).
  11. Pennsylvanian Fern ID

    Several years ago I collected these ferns in central PA. I am currently working back through my collection making sure that everything has an identification. I have most of the identifications down, but could use some help pinpointing or confirming these identifications. Any help is greatly appreciated. Thanks! #1- ???? - I tried to tip it in the light so that it is more visible. It measures about 53mm #2- Neuropteris ovata? #3- Macroneuropteris scheuchzeri? It measures 40mm #4- Neuropteris? #5- Neuropteris on the left? I know that it is Macroneuropteris scheuchzeri on the right #6- Macroneuropteris scheuchzeri? #7- ???? - It looks like a branch with thorns
  12. Plant, Insect?

    Discovered in 1960. From Central PA farm field. Approx. 4" x 8" Was longer but was used as door stop for decades and slowly chipped away. Appears to be sandstone IMG_0344.HEIC IMG_4221.HEIC
  13. I have been slacking in my posts the past couple of trips, so I figured I would catch up. First up are carboniferous plant fossils from McIntyre Mountain, PA:
  14. Starfish ?

    In the fall of 2011 I got of the train in Harrisburg on my way to Red Hill for my first dig with DVPS and waited for the rental car shuttle. The folks there voiced concern that this snow storm might interfere with the dig. Anyway, I dug this from under a snow covered stump up the highway at Swatara State park the next day. Looking at it recently, I noticed this shape that seemed different than the fenestrate bryozoans that were common in the samples. Any chance this is a starfish ?
  15. Road cuts question.

    I have a question on laws and rules on road cuts with nice shale beds. Am I aloud to dig there? What permission is needed?
  16. Hello to everyone, I was trying to put together a plan for a spring or summer trip hunting fossils. I am particularly interested in the animals of mahantango formation and would like to know if anyone is familiar with some public locations that allow people to hunt for the fossils from that formation, or at least do not prohibit this. If anyone can point me in the right direction that would be greatly appreciated, Thank you.
  17. Fern Prep

    My dad and I collected this large fern several months ago in PA and have since contemplated how best to prepare it in order for the fossil to be visible. When the material is dampened, the fossil is visible; but, when the shale dries, the fern kinda disappears back into the material. We read somewhere that coating the material in Butvar may darken the material and may make the fossil more visible; however, we would love to hear the thoughts and suggestions on this group. Any help is greatly appreciated.
  18. what is it?

    Found in Pennsylvania, it is somewhat light but has a little weight to it. It Also shows up on a metal detector.
  19. My dad and I recently took a trip to collect plant fossils at two locales near Centralia, PA. Given that St. Clair is no longer accessible to collecting, we found that this area offered the next best option for collecting similar fossil ferns. We came away with a lot of large samples of Calamites sp., including several pith casts that just fell out of the rock. We also found a fair amount of Annularia, Neuropteris, and Pecopteris. Here are only a few of our best finds. I hope you enjoy. If you disagree on an identification, please let me know; I am still trying to identify everything. Some Neuropteris from Centralia What looks to be the bark of Sigillaria
  20. Fossil ID request

    Wondering what these might be not exactly certain. Poking around in an outcrop of the Mahantango. Thanks!
  21. Pennsylvanian Plant Identification

    I collected at a deposit yesterday near Locust Gap, PA and came back with several plant fossils, including this unknown bark. My initial thought is that it of calamites sp. but the gap between the striations is much larger than what I ordinarily associate with calamites. The first two photos are of the unknown bark and the third photo is of what I know to be calamites. I hope you can see the difference.
  22. What is it?

    Found in Pennsylvania
  23. Is this a Conus nigromaculatus?

  24. wanting to go on a trip

    I'd like to go collecting with someone or a group in July. Anywhere in eastern PA or Northern NJ. Anyone interested?
