  1. Tips on a few finds

    Hi everyone, I'm looking for a bit of help with 3 finds from this weekend that I have 0 idea where to start with (bear in mind short of crinoids, trilobites, ammonites and belemnites I've not seen very much). All of these come from Warden Point on the Isle of Sheppey, UK. Lower eocene, London Clay formation. The first was recovered from the shorefront, the last two were found in-situ in the cliff face (loose, no hammering was required to remove them). This first one looks really exciting to me and for some reasons when I saw it I thought "turtle" but truth is I have no idea where to place this. The second one looked like a tooth to me, just an irregular shape I guess. As a piece broke off I can now see the interior structure and there is a clear layer of mineral/crystalline deposit on the surface, but beyond that I can't distinguish anything. This is likely to be nothing, but still I'd prefer to hear it from someone that has a better idea. The last one is probably the most exciting and puzzling of all as it is quite large. The curved shape and striated structure of this drew my attention to it and I decided to remove it from the clay and take it home for a closer look. Turns out I was right as there is definitely a hollow structure that I was able to reveal. As to what this may be, I could only guess as a large gastropod perhaps? Your mind races to stuff like dinosaur claws/horns/etc with some of these (very mature of me, I know), but it would be really interesting to hear any guesses that might fit the location. More importantly I would really like some advice on how I could extract the fossil from its matrix as it still has quite a lot of hardened clay around it and after going at it for an hour with a toothbrush and very tentatively with a small knife trying to pry off the clay, I decided to leave it alone for fear of damaging it. Thank you in advance for your patience and any questions that might help with suggestions I will try to answer as quickly as I can (if I can :))
  2. Claw from the Eocene of Virginia

    I just found this 7mm by 3mm claw searching matrix that I collected years ago from an Eocene site in Virginia. The site was a near shore, marine environment. I found a good number of turtle and croc fossils at the site in addition to fish, shark and ray fossils. However, I also found close to 100 bird bones of different species and several terrestrial mammal specimens. Unfortunately the specimen is not in the greatest condition. I've found lots of crab claws at the site but it is definitely not crab. Out of the possibilities of reptile, bird and mammal the claw looks like it is from a bird to me based upon the curve. What do you think? Marco Sr.
  3. Odontaspis or Jaeckelotodontid???

    From the album Eocene vertebrates of Ukraine

    Unidentified lamnoid anterior
  4. Asineops squamifrons

    The information on Asineops is scarce so I thought I'd do some research and make it publicly available. Asineops squamifrons is a Eocene fish and an incertae sedis. They are rare and are most commonly found in a fragile layer of the green river formation at smith hollow quarry. They can be found in fossil lake or lake gosiute. Fossil lake ones are bigger but rarer. I don't know the maximum size on these but I would guess 7-12 inches. Their scales a very distinctive in shape. According to Rosen and Patterson (1969) it may represent a intermediate between acanthopterygians and paracanthopterygians (which looking at a phylogenetic chart is confusing to me) , meaning their closest living relatives would be the troutperch and its allies (percopsiformes). Its relations to other fish are confusing and not understood but it bears some affinity to Nardoichthys (a Italian late Cretaceous fish which seems to be closely related to troutperchess) and prolates (couldn't find much info on this guy). Diagnostic features include the following: long premaxillary ascending process six branchiostegals unforked caudal fin with 14 principal rays (12 branched) cycloid scales full nueral spine on PU2 two epurals free second ural centrum two anal spines two supranuerals unserrated preopercular Pelvis girdle and cleithrum do not touch unfused lower hypurals sources: Wikipedia Enigmatic fish Oilshales topic @FossilDudeCO Fossil lake Specimens from top to bottom: @oilshale Fossil lake If you have anything to add, or a specimen to show off, I encourage you to do so! Thanks for reading!
  5. From the album Some of my best Sheppey fossils

    This is a beautiful calcite cast of the centre of a cimomia imperialis nautilus. You can clearly see the septa and siphuncle detail.
  6. Eocoelopoma fish skull

    From the album Some of my best Sheppey fossils

    The newest addition to my fish family. This is another beautiful example of the fish Eocoelopoma.
  7. The two specimens below are from the Eocene of Virginia. I’ve collected this site for many years and not found anything similar. They look like they are pieces of an echinoid. I’ve never found an echinoid, echinoid spines or pieces of echinoids from this site or any other site in Virginia before. EDIT: I should have put this information in the original post. These specimens are from a marine formation. They are very thin, almost paper thin. Yet they are hard and not flexible. Specimen 1 6mm x 5mm Specimen 2 5mm x 2mm Marco Sr.
  8. Glyphityreus Wetherelli crab nodule

    From the album Some of my best Sheppey fossils

    This is one of the better crabs in my collection. Both claws, the carapace and parts of most of the legs are contained in this tiny nodule.
  9. Hoploparia lobster

    From the album Some of my best Sheppey fossils

    This is an excellent example of a hoploparia lobster with its huge claw still attached attached.
  10. Xanthilites bowerbanki crab

    From the album Some of my best Sheppey fossils

    This is a fine specimen of the xantilites bowerbanki crab. Quite rarely found in such good condition this is one of my favourites!
  11. Basinotopus carapace

    From the album Some of my best Sheppey fossils

    This is a beautiful little crab, unfortunately it is encased in a very hard nodule making any further prep very difficult.
  12. Striatolamia intermediate tooth

    Intermediate tooth of S. macrota.
  13. Striatolamia intermediates

    From the album Eocene vertebrates of Ukraine

    3 intermediates, most likely from Striatolamia macrota.

  21. New species or genetic mutation?

    I have been blessed this summer to have some amazing finds up in Green River. A couple of them come in the form of strange pathologies on a common fish. The Priscacara (or Cockerellites as it is now known) Is quite a common fish to find in multiple layers of the Green River Formation. The Cockerellites is closely related to modern perch, and is a highly prized fish due to it's unique appearance! I know there was a paper recently written (I believe in 2010) by John Whitlock, but I cannot seem to find it on any open access sites. Part of his debate for a new genus is fueled by the fact that serrata and liops have differing numbers of dorsal and anal spines. I present to you today 2 of my more uncommon finds from Green River showing variations of these animals. 99%+ of the Cockerellites found have just 10 dorsal spines, I present today my 2 unique finds from this past dig season! Fish number 1 was discovered on July 29, 2017 Fish number 2 was discovered on September 23, 2017 The first picture shows a Cockerellites liops with 11 dorsal spines. this second photos shows an even more perplexing mutation. This Cockerellites liops has 12 dorsal spines!! While multiple fish have been found with 11 dorsal spines, I am unsure if anyone has ever found a fish with 12 dorsal spines. This is a very unique occurrence and should this fish be a new variant it will be donated to Fossil Butte National Monument! Even though he is missing most of his anal fins, this fish could still be a very important specimen to show mutations. So, do you think these 2 fish could represent new species within the Genus? Or are they simply mutations?
  22. Dear Friends, This time i'd like to show something very rare ( for Baltic Amber ) Neuroptera ( Dustywing ) Coniopterygidae Archiconiocompsa prisca (Enderlein) ID found with help of scientists from Germany Size of the body - 2.5mm, max - 5 mm First Dustywing in my career, they are very very rare, especially in condition like this buddy from the pictures. Enjoy ! Artur
