    Isotelus gigas

    From the album: Swatara Gap

  6. Today I went to visit a friend of mine who purchased a flat of swatara gap material recently from an old collection. After hanging out and chatting for a bit he mentioned he had something to show me. He revealed a flat of incredible material to say the least, Two Acidaspis, a nearly perfect 3 inch Isotelus, and a massive Taeniaster flanked by two carpoids. The other specimens in the box were more common but impressively complete. I made an offer on the spot, after negotiating for a little we made a deal and I went home with the collection I knew most of the specimens had been collected by my g

    Swatara Gap PS Starfish

    I've been collecting at the actual Swatara Gap site since I was a kid and over the years collected most of the trilobites and starfish that were found there. However, there are some starfish that I would like to verify. I've tried literature searches and know there is a 1989 paper on them , but I cannot find it on-line. Hopefully, one of you guys can help with identifying these specimens. Any help would be appreciated/
  8. Hey everyone, Thought I’d share a recent acquisition of mine with you all! This is an extremely rare odontopleurid called Diacanthaspis sp. from the closed Ordovician locality at Swatara gap. These trilobites were not often found at the trilobite beds at Swatara Gap but rather in the echinoderm beds. One publications states that in 100 hours of digging one could expect one articulated specimen. It is probably the 7th 8th most rare trilobite species at Swatara behind Proteus and Platylichas.
  9. Hello everyone! Today I acquired a specimen that is of a rarity that's nearly unparalleled. The specimen in question is the cuticle of a Eurypterid from the famous, classic, and closed Ordovician locality at Swatara Gap. I believe it is undescribed and I can tell its a eurypterid for sure by the scaling pattern on the cuticle. Eurypterids aren't unheard of at Swatara Gap but I have never seen a specimen or even known about a specimen other then the one I have. They are extremely rare and were probably over looked by collectors due to not knowing what they were. I acquired the eury

    Michelinoceras Soft Tissue?????

    Hi everyone! I may be wrong the way I was with trilobite gender, but is this soft tissue????? It might just be a stain on the rock, but it is inside a Michelinoceras body chamber, and looks similar to pictures of cephalopod soft tissue fossils (ex. the squid and octopus from Lebanon). Is this just a false alarm or am I really on to something here?
  15. Bringing Fossils to Life


    Hi everyone! I was going through my Swatara Gap fossils when I came across this specimen, which I had originally thought to be coral. However, it looks similar to pictures of Spyroceras I've seen. Can anyone help? The first picture shows the texture, the second picture is a cross section, and the third picture is an imprint on the other side of the rock that looks cephalopody.

    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.
  17. As I learn more and more about this hobby of fossil collecting and study I'm unfortunately also finding out more about those once great fossil collecting sites that have been destroyed or we no longer have access to; ones like Swatara Gap, Linton, Ohio, Eighteen Mile Creek, Centerfield, just to name a few. There are also others like Inversand, NJ and St Clair, PA which are threatened with closure. I would like to invite the membership to share their thoughts and (feelings) about what could possibly be done to possibly reopen some of the closed sites and to keep those that are endangered open.
