  1. Hey everyone! This will be my first attempt at a trade in the TFF. Im offering a variety of fossils from the Price Creek Formation of Humboldt County, Northern California. This formation has been dated to late Miocene early Pliocene. As far as to what I’m looking for in this trade, I love all things Mollusca! Gastropods, Bivalves, Ammonites, Belemnites or Brachiopods, I’ll take them all. Invertebrates of any kind will strike my fancy though. The weirder the better. I’ve seen some Ram’s Horn Oysters that are awesome! I have no qualms about trading for these as a whole set, however shipping would be cheaper. I’m willing to ship anywhere in the United States, if your international I’m afraid that you’ll have to absorb that cost. I really appreciate all the knowledge that members have been forthcoming with sharing. Please pm me if your interested. -Nick
  2. March 17th, 2020 Peace River

    I've spent the last few trips Socially separating on the Peace at Zolfo Springs. Yesterday I found some pretty interesting stuff. I've switched back to a 1/4 " screen for a while because the 1/2" and the extended shovel handle was killing me. As a result, I've gotten a ton more small shark teeth, but have been able to process a lot less material. This was the total take for Tuesday. The invertebrates are the most interesting I think. In the lower left corner is a juvenile Abertella aberti with some minor damage but an intact perimeter. I've got a question about the sea biscuit though. It is clearly a Ryncholampas sp., but which one? This is Hawthorne group, not Suwannee, so should I assume it's R. chipolanus? Close up pictures follow.
  3. Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA
  4. Echinoid?

    Is this an echinoid?
  5. Heteraster?

    From the album Fossil Collection

  6. Pinnules and echinoid spine?

    Hello again, I find these crinoid parts (I think) all the time and just want another opinion on what it is. I think number 1 is crinoid pinnules. Number two is the first and only one of these I've found so far here.(Mississippian redwall limestone, Mooney member). It's about 1/4 inch long and I'm guessing perhaps an echinoid spine? I appreciate any input you guys might offer. Thank you Bob
  7. Moroccan echinoids

    I have these as Goniopygus menardi. These are from Morrocco. No stratigraphic info or specific location. Does that look correct? Scale in mm. I have these as Asterocidaris spines. Also from Morocco. Thanks for any help.
  8. It's a New Year! Time for New Fossils Finds! i enoyed a post on the FB Fossil Forum of what are your "dream fossils". So this is a New Years version....what are the fossils you HOPE to find this year? I know for me, it's that danged Big Echinoid Cidarid that has been eluding me. Also, a psudodiadema echinoid. I have partials of both but really want a whole one! So, Universe, or whatever Omnipresence is Available, that's what I want to find this year! What are YOU on the hunt for? We want to know! Cidarid: (I "borrowed" the image off the internet....ya'll might recognize it from a post here in the forum) ! Pseudodiadema:
  9. ID confirmation request

    Good morning. I have a fossil Echinoid that I would like to verify. The information I have is Eupatagus antillarum, Pliocene. It's from the Caloosahatchee Formation, Lafayette County, Florida. Comments please.
  10. Echinoid ID

    Found recently in Split, Croatia, near Adriatic sea, on hill called Marjan Location If someone can tell the species? Thanks
  11. An Echinoid from Morocco?

    These were in one of those sets of mixed fossils you can get. Must've first got them over 10 years ago. Anyway, since most of them were from Morocco I assume this echinoid is too, as it has a similar looking matrix to the others. All the label says is it's an Echinoid from the Cretaceous, but as some of the other labels in the set were clearly wrong it could be from another period. Its one of the last fossils from this set I've been unable to identify, so I'm hoping one of you guys has one or knows the genus and where it is indeed from.
  12. Again, thank goodness for cameras and closeups!! I thougth this was a large orbitolina when I found it, but noticed that there was an odd pattern on the underside. I just figured it had some strange mishape. But then I was looking through @Uncle Siphuncle's Fossil collecting reports and ran across something that looked very similar - floating crinoid Peocilocrinus but they were from the Paw Paw formation in North Texas and this is from the lower Glen Rose in Central Texas. So I realized i needed to get a better picture and lo and behold....it has interesting pattern on the backside!! I remembered a picture I had seen of a starfish dermal plate or something that had these same striations on it. Can anyone help me ID? @erose or @JohnJ? Thanks for your time!! close up
  13. North Texas Ammonites

    Finally got some time to do some fossil hunting during my travels. This was as I was going through North Texas. Found some beautiful partial ammonites with sutures showing, and one (my favorite) ended up having three echinoids still in it. I plan on leaving them in there, of course. This guy was like 50 pounds Before cleaning with a brass brush After cleaning The whole view Too big to bring home. Maybe I'll grab it next time. I'm so sad I lost this little ammonite on the way back to the car See if you can find the echinoid I missed, but found afterwards while looking at this picture
  14. Hello all! Went a hunting in the Glen Rose Formation yesterday and found a few nice salenia texanas...I think. The first one, has the rounded cap, the next one is a bit more "indented" But the last one has a very different looking "cap". Is it perhaps something else? Also found this tiny spiral, I am thinking its a worm, but never seen one do this perfect spiral. It's so tiny and poorly preserved, unfortunately, pictures are hard to get. Any help will be appreciated!
  15. Cool road find

    While working on a gravel road I found this beside my truck. I thought it was a piece of broken pottery at first.
  16. A recent acquisition that I bought just because it's beautiful. Impressions of cidarids crop up quite often in Cretaceous flint but I've never been lucky enough to find one (and I live in the wrong area). Probably Temnocidaris sp., Upper Cretaceous, Santonian, Kent coast, southern England. Test fragment 13mm across

  21. Jurassic Echinoid

    From the album Fossil Collection

  22. The first week of June I managed to break away from a European excursion with my wife to do a couple hours of collecting in northern Switzerland! We found a boatload of late-Jurassic (Birmenstorf-Member) ammonites and one nice echinoid which should be awesome with some prep! Funny part, on the drive back my wife mentions finding an ammonite that looked like there were nipples on it. Not until we get back to the apartment and start cleaning things off do I discover it was the echinoid she was talking about! *shes a rookie I could use some help with ID confirmation and IDs in general. Taramelliceras callicerum Ochetoceras canaliculatum Paracidaris blumenbachii Trimarginites arolicus (easy because of the grooves on the keel) These have fine ribs, are super thick relative to size but have goniatite type 'sutures' thoughts? (I dont think the far right one is equivalent, i have some other pictures of that one) Assumedly all of these are Perisphinctes, but I cannot tell the difference between all of those ribbed ones to save my life. They may need some prep to help determine Fatter, round keel. Glochiceras? There are quite a few that look like Trimarginites but have smooth keels. Thoughts? Are they just more weathered potentially hiding the grooves on the keel? These, from the paper most closely resemble Glochiceras crenatum but I dont feel like that specimen is closely enough related. I would think those spines along the keep would be easy to ID. One more, its a bid weathered but I figured someone might recognize it. Has some decent sized spines along the edge of the keel (arrows) Euaspidoceras oegir, maybe? Thanks for any help!
  23. I was at the chalk cliffs at Seaford in April this year hunting for echinoids. However, I only found time to clean and prep these fossils this week, using a safety pin, a brush and water (Very low-tech, I know!). UKfossils.co.uk states the rocks here are Cretaceous, 89-86 million years old. I found a fist-sized chunk of chalk that yielded two enchinoderm plates (picture 4) and a very small, unknown fossil. Pictures 1-3 show the unknown fossil. 1 division on the ruler is 1mm. It is perfectly spherical, with a diameter of about 4mm and has raised dimples covering its surface. There are at least two holes, but they are not opposite each other, and I am unsure if these are biological features or just preservational artifacts. My thoughts are this is either a bryozoan or a small echinoid, but I am not sure.
  24. Aristotle's lantern ?

    Hi, I found this crushed echinoid in an Upper Campanian/Lower Maastrichtian stage of the Pyrenees. "Not much of a piece", I tought (likely a Micropsis or a Phymosomatoid). But I wonder if this can be its crushed Aristotle's lantern: Close-up: The other side:
