  1. Hi all, I have fossils from Singapore's Jurong Formation, aged from late Triassic to early Jurassic (235 - 175 mya). Some were found over 10 years ago by a fossil-digger while others were dug up recently by the two of us. Several specimens have been handed over to our local museum. However, no one really knows what family or genus these bivalves belong to. I was hoping you guys could help. Specimen 0A Specimen 0B Specimen 0B alt view Specimen 0B alt view
  2. ID gastropods

    These are 2 of the largest gastropods that I have come across while digging fossils out of these sandstone boulders. I'm not sure but I think the first one is maybe a solariella maculate. I can find photos of what looks like the second one but I can't seem to place a name to it. Location, near Palmdale, Ca., most likely from the Pliocene period.
  3. Hi Eveyrone! I know that ID'ing bivalve steinkerns is difficult if not impossible. But these are such an unusual shape. I have not found anything in my hunting - and I've found a LOT o bivalves. These are from Blanco TX - Glen Rose formation. They look like a bit like Trigonia (or pterotrigonia) in shape but not quite so "fortune cookie" curved , but have the really dramatic "underside" of something like an Artica. I do not have the Houston Gem and Mineral Society book on Bivalves, so if anyone does...would you mind seeing if you can find this one? It is really intriguing me! Thanks!!
  4. ID thck bivalve with spines

    I have been told by a scientist that this belongs to a cockle but I'm having a very hard time seeing it as one. I have found several bivalves on line that have spines but can't find an exact match for the pattern on this thing. The thick section is a little over 5mm and the thin section is about 2mm. It does not slope down to 2mm it has steps in it, which I can't find on any bivalves on line. Also, the spines on all bivalves I've seen appear to fan out as they move from the rear (hinge area) to the thinner forward area but these spines are coming together at what appears to be the thinner area and fanning out at the thick section. Has anyone ever seen anything like this???
  5. Hi all! I managed to go on 3 large fossil hunting trips this weekend and pulled in easily the BIGGEST haul so far with the most variety as well! The first two pictures were from Mimico creek and the rest were a mix of Humber river and a separate section of Mimico creek. I managed to pull in my second trilobite from the area so that was very exciting! Also pulled a bunch of stuff that I was not able to identify: /\ This was the haul from last Friday night /\ This is the trilobite I found!!! Very excited to have a second one - its been a while since the last one I found /\ This was the full haul for the weekend trip at Mimico and Humber /\ Some Orthoconic Nautiloids as usual. Although it seems that this isn't just the same species I usually find as some of the patterns were much smoother than what I usually find A couple decent looking Crinoid stalks /\ /\ Lots of different shells this time, with a nice range of lined shells as well as 'mussel' looking shells (don't know the scientific names for these ones yet - sorry :/) /\ A close-up of the real nicely defined deathbed of TONS of shells! Unfortunately the hammer I used for cracking bounced off this rock and mashed my thumb in so that wasn't very fun. But its healing up nicely so I'd say it was worth it haha /\ Variety different sizes of coral (if you guys could help me identify which type that would be sweet!) /\ These were the weird ones. I'm not even sure if these are even fossils but I figured I might as well take em just in case - better safe than sorry!! (I am posting these two in identification later!) I was very proud of this haul! Lots of diversity compared to the usual hunt which is nice because I'm kind of getting a little tired of the mountains of Nautiloids we have piling up in the collection Let me know what you guys think of these ones!!! -Em
  6. Runswick & Kettleness finds

    Had a walk from Runswick Bay to Kettleness and here’s a few of our finds
  7. Unknown from Penn Dixie

    Hi all, here is another find from Penn Dixie not sure what it is maybe a bivalve or brachiopod. Also the outer layer used to be a very thin calcite, most flaked off but a bit is still left. Thank you.

  9. Cole Hill Invertebrates

    I went with the Delaware Valley Paleontological Society to a few spots in Central New York last month. Cole Hill Rd. in Hubbardsville has several outcrops on private land where the owners are willing to share with fossil hunters. We scrabbled up and down the scree - Whee- and found our fill of trilo-bits, including one Dipleura cephalon covered with druse calcite, plus oodles of brachiopods, nautiloids, straight-shelled cephalopods, gastropods of all different shapes, and bivalves. I learned a tough lesson that afternoon. Always wrap your specimens as you go. Not only will they keep from breaking, but they are easier to find when your bucket tips and tumbles down the hillside across countless tons of scree There were lots of pained faces around me as I hunted down the things I'd already found.. It took me half an hour to recover everything I could, but the best ones managed to make it home. Dilpeura trilobite cephalon Another trilobite cephalon, found by someone else in the group. This one is covered in sparkling calcite. Crinoid holdfast? with Ptomatis rudis gastropod unknown, probably nautiloid Cornellites fasculata bivalve Palaeozygopleura sp. misc. unknown brachiopods If anyone has any ideas, I'd like to hear them. This spine-shaped object is about 6 inches long. I'd discount it as variations in the rock color, but the left end is curved outward from the matrix. Worm trace fossil. They made carpets of these on the sea floor.
  10. I have no idea whatsoever

    This is roughly 2 1/2 inch in length. At its widest point 1 1/2 in and a 1/4 in thick. Any help identifying it would be much appreciated
  11. SW Florida Pearl Fossils?

    Hi everybody. I'm hoping someone on here can identify these. Last Saturday I was digging in the yard here in Alva to plant some citrus trees. At about two feet down in this area it's all coral and i found this conglomeration wedged under a cypress root. the tree is over 4 ft in diameter. i thought these were lizard eggs but after gently brushing the shells out with a soft toothbrush and dawn soap, i think these might be pearls. two of them actually did separate as you can see they're on the desk. we're seventeen miles from the ocean and this property was a cypress swamp prior to our house being built in 1974. Any thoughts on these ? My wife wants me to encase them in resin because they're unusual looking . Thanks.
  12. Ooops, sorry, I meant to post my request for fossil ID in this forum but I’ve never been on a forum before and ended up posting it in the wrong one. Please can you have a look at my post in Member Introductions. Thanks everyone. Doh!
  13. No idea about this one, is it the inside of a scallop-like shell or is it worm tubes or maybe coral? Found near Bath (I think, as it looks like it’s in limestone). Any ideas for me? This is the “inside” view, I’ll post some other views after, (pic files too big)
  14. Pododesmus sp.

  15. What could it be?

    Hello, please could you help me to Id this fossil? I do not know were it come from, I bought it in Milan. Thanks
  16. Interesting Yorktown Bivalve

    I found this bivalve in a clump of matrix that was attached to one of my other finds on a recent trip to the Tar River with @MikeR and @AshHendrick. I have never found one of these before nor seen one. Pliocene Yorktown Formation Rushmere Member. My best guess on this one is Pododesmus sp. It is 1.53 inch long (39 mm) and 1.42 inch wide (36.3 mm)
  17. Cool microfossils

    Hello all, I believe that one of these is a foraminifera, not too sure if that tiny bivalve and snail would be considered one or not. Anyone have any ideal what period these may be from? Was digging some old bivalves and gastropods out of some sandstone and came across a boulder that had hundreds of microfossils mixed in it's debris. The size range from what you see here to less than 0.50mm. Some if this stuff is really cool looking.
  18. So, I have two more fossils (I think), that I could really use help with.... Both found in same location(s) and formation(s) as my prior posts. The first, looks like the impression of a mollusk/shell to me (about 3/4' in diameter) ??? The second, I cant even begin to guess as I would probably be wrong anyway. lol Its corkscrew in shape and about 3/4' long. It left a mirrored impression of itself on the opposing rock. Any thoughts???!!! Thanks in advance. :0)
  19. Wilkingia Sp.?

    Not my best photos, but a quick dimensional Wilkingia that I found over the weekend. Identification is likely but not solid.
  20. 2nd fossilized pearlescent shell found underneath what I think may be a California mussel?
  21. bivalve that looks like a "toe"?

    Hi, All. I don't have a clue what these are, but I'm guessing a bivalve of some kind? They came from the desert sand near Agadez, Niger, but that's all I know. The street merchant I got them from thought they were dino toes, but I'm guessing not.... The thing that confuses me the most (other than the fact that I haven't been able to find any pictures of bivalves that look like this) is that it doesn't look like the "shell" would actually close like a clam or mussel. Any and all help in identifying these would be most appreciated! Rob
  22. I've been busy whacking concretions today (ok not so much whacking as gently knocking around and around until they give way), and this is the first one where it contained something that I suspect can be identified. Anyone know what bivalve this is? It's from the middle of the formation, so I think that means Lower Zemorrian? At least that's what it was called in the 1960s when the relevant report was published, I dunno if it's been standardized to some other designation since then. The shell measures 3cm across.
