  3. Almost micro

    Hi everyone! Oxfordian again This time it's the turn of small shells from Peski Quarry, located some 80 km south-east of Moscow. It's something like the Moscow region's Jurassic gastropod heaven. For some geologic reasons, ammonites do not get preserved there while little gastropods and bivalves do. It's also the only place dinosaurs were found in the Moscow region. As of today the continental sediments are depleted, but the marine ones are stil abundant. The quarry extracts Carboniferous limestone, removing Callovian marl and Oxfordian clay. The clay is then discharged in open piles - small shells of exceptional quality are washed up during rains. Below are pictures from two trips: one in winter (with snow) and one recently. To get to the Jurassic part of the quarry fastest you have to go through woods along a small river:

  5. Verrucocoelia

  6. Porospongia marginata

  7. Hi all! A bit of development to the Frozen fossils topic. It's the same Moskva river Bronnitsy Oxfordian, but some 5km upstream, where you can find a bit younger layer of Amoeboceras serratum ammonites (earlier it was Amoeboceras alternoides layer/zone). The difference is mainly in the keel, it's less pronounced. The layer is accessible only in winter. Dont expect it to be breathtaking, the preservation is unfortunately worse and the fossils are more scarce. The shore:
  8. Hi there, I'm working at the moment on cataloguing my collection. 98% or so has been self collected over the years. Lately i've cataloguing my fossils from "les Vaches noires" cliffs in normandy / France. Im not finished yet, but i think i should share. So heres my flickr galery "les Vaches Noires " : https://flic.kr/s/aHsmKUCQse i hope you will enjoy.
  9. Polish Ammonites

    Looking for assistance with the identification of these ammonites from Poland (either Niegowoniec or Odrodzieniec). Age is late Jurassic; Oxfordian. Orthosphinctes? Perisphinctes? The best that I can tell, the ribs on the big one are only bifurcate. Anyone have an idea from which formation they may have come? @Ludwigia
  10. Frozen Fossils

    Hello, everybody! Today I will present you an unusual way of fossil hunting, popular in Moscow - digging ammonites from under the snow! You'd expect that, wouldn't you? Well, it doesnt always involve snow (but often does), especially this year when we don't have it yet, but the site I will be talking about is available only in winter. The Moskva river level is intentionally dropped for "winter navigation" which typically happens at the end of November. Places located underwater become available which is also the case for Markovo foreshore situated some 40km to the south-east of Moscow. The site is famous for Oxfordian ammonites of great preservation quality. Descent to the river. In summer the water level is hiigh enough to reach the pier.
  11. Swiss Ammonite ID needed

    Hey guys, So a month ago I went on a hike at 3000m of altitude to this fossilferous site near Plaine-Morte, Switzerland. There I found mostly ammonite fragments including : Sowerbiceras, Perisphinctes( Properisphinctes?), Deshayites and a few belemnites (Hibolites?) I contacted a fossil expert on fossils and that knew a lot about fossils from Switzerland and he indicated me the genuses above as well as the age : Upper Jurassic, Oxfordian ( 163-157 mya ) I went back to the same site where I found this almost complete ammonite. I have no idea what it is and don’t really want to disturb this expert again since he is very busy. Do you guys have any idea on what it could be??? It is very interesting indeed, one side is still covered In matrix. Thank you for all imput and don’t hesitate to ask me for more info! Kind regards.
  12. Hey all, I thought I would make a thread to show some of my shark teeth that I have collected from the Oxford Clay formation (mainly the Peterborough Member), feel free to comment if I have misidentified anything! Pre-Apologies, some of them are quite small.. Cheers, Jacob.
  13. Help identifyng these ammonite species

    Hi, I found these ammonite specimens in the Oxfordian Ammonitico Rosso facies from the Baleriac Islands, Spain. I know that the preservation state is quite poor but I would like to get some help identifyng the genus and species. I am not familiar with ammonite description but here you have a very basic description of what I see: Specimen 1: No ribs, oxycone/discocone, involut, carinate? Specimen 2 (Taramelliceras sp?): two pair of ribs (primary and secondary), oxycone/discocone, involut Specimen 3: No ribs, discocone, carinate? Specimen 1

  18. Ammonites, Poland ID

    2 more Ammonites of Zalas, Poland, Oxfordian Jurassic. did someone come back to determine them? Thanks a lot to everyone.
  19. Ammonites, POLAND

    Ammonites of Zalas, Poland, Oxfordian Jurassic. Can Glochiceras cornutum Ziegler 1958 be? Thanks for your help.
  20. This Christmas I spent 4 days of fossil hunting with my girlfriend on the French coast. The planning was 2 days in Normandy at the "Vaches Noires" cliffs in villers sur mer and one day at Cap blanc Nez near Calais ( we finally extended the trip with one extra day near Boulogne sur mer ) Day 1: The first day we got at Villers sur mer after a 4h drive from home. Once at the cliffs we had to wait a little while since the tide wasn't low enough, but the beginning of the cliffs were already accessible. The fossil fauna was very variable, we found echinoid spines, echinoids, gastropods, bivalves ( lots of oysters like rastellum ) , ammonites ( mostly fragments ), brachiopods... Our best find of the day was a complete Cardioceras sp. Day 2 started with a visit to the local museum. in the afternoon we got back to the beach. Natalie found 2 ammonites, one of them was a really nice Euaspidoceras. On day 3 we went back North to Boulogne sur mer, here we looked through late Jurassic deposits. Day 4: The last day of our field trip, we visited the late cretaceous of "Cap Blanc Nez"
