  1. Hi all. This is from Swatara State Park in PA (ordovician/devonian). Many shell imprints, which are hard to see the way I took the photo, but my son and I were wondering what the little starfish would be. It's very small, maybe 5mm. Anyone have an ID? Thanks so much!
  2. During a trip today with a friend I found a large flexicalymene meeki. As well as some parts and partials of others. I also found some good gastropods and miscellaneous interesting fossils. The large flexi would be around 2 inches long if stretched out and it is just over an inch wide.

    Conularia sp.?

    It's an Ordovician decalcified mould of a....? Scale bar 5mm. One person told me that it might be arthropodian (for example the backside of an unidentified librigena), but all the others don't have any idea about it. I found on the "Treatise on invertebrate paleontology" (Part F - 1963) at p. F65 a resemblance with Conularia gracilis (first of all because it seems to lack transversal rows), also supported from a few very old pics from Google images. But I didn't find any modern confirmation of the "Conularia gracilis" existence. It could be a Conulariid (only 1 has ever been found in this formation)?

    Horn Coral cleaning?

    Title says it all, this is my only rugosa fossil and its half in a martrix, how would I go about removing my peice from it? What tools would I need, and is it possible? Thanks in advance!
  5. I found this clam buried in mud along Joshua’s Creek in Oakville, near Lake Ontario, the hotspot of Ordovician fossils. Measurements are 7cm by 6cm. I’m particularly intrigued by the growth rings, since they protrude out rather visibly and considering I’ve never seen this in any other kind of fossil or living clam species. Can anyone help with identifying what species of fossil clam this is?

  7. 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.
  8. I went up to Georgian Bay Ontario today to a beach with chunks of Ordovician shale in the hopes of finding a conulariid. Unfortunately it's late in the season and the shale you usually find in early spring is mostly gone by this point. So there were a few small finds here and there, but not much to write home about. I don't know if anyone can see anything in these rocks I missed. Not great pics, I know. Pseudogygites latimarginatus pygidium Some crinoids And finally some Treptoceras nautiloids I think?

    Crinoid Stem or Cephalopod

    I picked this up on my last trip along AA highway in Kentucky. It's about 4cm long. I thought it was a crinoid stem. Recently I saw a YouTube video where someone found a fossil very similar to this and called it a cephalopod. So that left me confused. So I figured I should just post and ask here. (If I need to provide more information or pictures please let me know)

  11. Congrats to @Spongy Joe Joe Botting and associates on this exceptional new discovery! "New fossil sponges from the latest Ordovician (444 Ma) Anji Biota are interpreted as crown-group euplectellids, within the Venus' flower basket morphological group. Two species are described here (one in open nomenclature), with a range of characters limited specifically to the modern group. These new occurrences extend the known record of the family by more than 300 myr from the previous earliest record, in the Cretaceous. The date of the Anji Biota is substantially older even than molecular clock predictions for the origin of the family (Carboniferous/Permian), and indicates a long cryptic history of the group. The deep-water setting of the Anji Biota, combined with previous records of stem-group rossellids, suggests that hexactinellids experienced a long history in the normally unpreservable deep-ocean environrnent that they occupy today. This new discovery thus highlights our lack of knowledge of the early evolution of bathyal to abyssal ecosystems."

  12. Hi folks! I’m kind of stuck on this one. I presume this is a gastropod and not a cephalopod because of its small size (diameter around 2 cm). But what order, family, genus and species? Its found at Mt Billingen in Sweden, in a layer from middle Ordovician (middle to upper Darriwilian).
  13. Visiting family in Kentucky and went to the Maysville Cut for 2 hours yesterday. Found some neat things. I wanted to find a trilobite, but no real luck. I think I may have found a piece of one.

    Weird fossil

    Hello all I was relooking at a piece I obtained many years ago. It has a beautifel cephalon of Trinucleus fimbriatus, which was the reason I bought it. I noticed this weird, rond fossil in the same piece. I was not a member here then and I didn't found it online. I forgot about the object until today. Now I want to know what it is. Does anyone here has an idea? I thought It might be one of the early development stages of a trilobite. It looked like a protaspis but is way to big (online they say protaspis are less than 1 mm, while this piece is 4mm) It's from the middle Ordovician of Builth Wells, Wales. Thanks already.
