  1. Ammonite hunt in Northern France

    We are back from a very windy fieldtrip to Cap blanc Nez in France. The wind covered a lot of the rocks with sand and sea foam ( https://en.wikipedia.org/wiki/Sea_foam ) which made fossil hunting rather difficult. We were helped by a local collector in the morning who guided us through the Turonian deposits of this site where we rarely colect, here we got 2 big ammonites. One of them was a Mamites nodosoides, this species as been on my wishlist for a while, so I am very happy with it In the afternoon we prospected the Cenomanian side. her we found the usual Mantelliceras and Scloenbachia ammonites. The prospecting site: ( we did see the coast of the UK on the other side of the channel ) Some of the ammonites we found: The Mammites: pictures of the prepped specimens will follow during the next week.
  2. Rudist ?

    Hi, a friend of mine told me he found some Placentyceras in a place where the geologic ages go from the Albian to the Turonian-Santonian, but most of the stratas of that place are Cenomanian. I believe this fossil is not an ammonite, but rather an Oyster or a rudist. I mostly think about Requienia or Toucasia. The geologic file mention the name of Toncasia bayleia. Do you know if Toncasia is a synonym of Toucasia and do you think i'm right thinking this is a rudist ? Lenght : 7 centimeters.
  3. on the last fieldtrip from this saturday I got a new batch of ammonites to prepp: the first one was realy easy to prepp, it was a small but well preserved Schloenbachia varians. next up is a Mantelliceras, I broke it in 3 pieces when extracting it from the chalk. I let the specimen dry at home and glued the pieces back together, I then prepped the specimen. After this step I grinded the some matrix residue left from the matrix and mixed it with a little bit of water and PVA glue, I used this mixture to fill and restaur the gaps in the ammonite. once dry I gave the ammonite a Paraloid B72 treatment for consolidation. I'm very pleased with the results
  4. This saturday the tides were ideal for a whole day of prospection at the foot of the chalk cliffs near Calais. We got there early in the morning when the water was going away from the cliffs. At the parking we were greeted by a veteran collector from this location, he took us along to the northern part of the site in search of big Turonian ammonites. A first for us since we've only collected more to the south in the cenomanian deposits. With his help we did find a couple of ammonites including a big specimen. around 1pm after lunch we parted ways and we went to the southern part of the site in search of cenomanian fossils, most of the beach was covered in sand, making it harder to find some decent boulders on the beach to break open. but the usual Schloenbachia and Mantelliceras ammonites did show up. we ended the day with dinner in a local tavern before heading back home whit a new load of fossils to clean and prepp. A Lewisceras Ammonite: A large Ammonite, I still have to prepp and Id it propperly: the extraction of the large ammonite: A nice find from Natalie: under the sand on the beach Albian deposits are present, but not visible, from time to time som fossils from those banks are washed out deeper in the sea and washed ashore. She found a nice Hoplites ammonite lying around on the beach: more pictures of the area: Schloenbachia varians: Mantelliceras specimens in situ: part of the fossils that made it back home: Pictures of prepped specimens will follow later
  5. Kem Kem fossil

    Hello All I prepped this fossil today. First decent prep job so I am extremely happy I could do this. The fossil is from the Kem Kem beds and is nearly completely hollow. Before I prepped it it didn't look this hollow, so I tough it would be a vertebra. Now I think it's a skull part. I have no idea from what or from what part this is. What do you all think? It's not that big, about 10 cm. @LordTrilobite, @Troodon, @Haravex Thanks already for your help. Greetings.
  6. this evening part 2 of the preppwork on the ammonites we found this weekend: Next up is a Schloenbachia varians of the Cenomanian of Cap blanc Nez in France: work in progres: the end result: the 2nd one of the evening was a Mantelliceras saxbii found by Natalie from the same location: The specimen is a little compressed and I thought that the center wasn't preserved, I was wrong. Work in progres: the end result: both specimens:
  7. The compressor is fixed (more or less ) so I prepped 2 of the ammonites we found this weekend. First one was the Hypoturrilites sp. : work in progress : the end result 2nd one is the Mantelliceras mantelli with inoceramus found by Natalie81 work in progress: the end result: both specimens, ready to go in the display cabinets
  8. How to prep Kem Kem fossils?

    Hello all At a fossil fair last sunday, I obtained a lot of Kem Kem fossils. Some look very interesting (skull parts, turtle carapace...) but I can't ID them very well since they are still covered in matrix. Now this matrix actually exists out of cristals that resemble aragonite. I have no idea how to prep these without damaging the specimens. I have about 10 specimens I want to get cleaned up, but unless this is very easy, I don't dare this. Any place where I can get these fossils prepped? Greetings Thijs
  9. This Saturday Natalie and I hit the road towards the jurassic and cretaceous clifs in the North of France. This is a 2h trip from where we live, so we left early to make most of the use of the favorible tides on those beaches. the 1st stop were the Titonian deposits near Wimereux, not the most easy place to find fossils, but with patience some nice fossils can be found. Th big problem although on this trip was the wind... this made it relatively hard to search for fossils. we did manage to find a couple of jurassic ammonites, one of them was more than 30cm in diameter but needs a lot of cleaning. In the afternoon we went to the beaches at the cretaceous clifs near Calais. here again the wind gave us a hard time blowing a lot of sand in the air. Although the harsh conditions we did find a few decent cenomanian ammonites, including a nice heteromorph turrilites sp. pictures of the Titonian deposits and finds: pics of the ammonites of the cretaceous site:
  10. Buda formation crabs

    I thought I would check out a small exposure of what I think is Buda formation, I wasn't expecting much but I thought maybe I might get lucky, boy did I. The most interesting finds were two crab carapaces IDed as graptocarcinus texanus, (thanks Dan) enough talking, pictures!
  11. Cretaceous Halysites?

    Is this a chain coral between the sutures of the ammonite Metoicoceras? About 4mm long (photo taken thru microscope). From the Cretaceous (Cenomanian) Tropic Shale in Utah.
  12. Pseudoscorpion

    Burmese amber is around 99.6 mya. There are various other inclusions in this piece. Edit: According to Danilo Harms from the University of Hamburg, this is a juvenile Chernetidae member.

  16. Fairly recent bit of opal fossil research

    After learning about Weewarrasaurus, I thought it'd be nice to report the 'lesser-known' recent bit of research about the opalised fossil site Lightning Ridge (New South Wales, Australia) It's basically the most up-to-date paper dealing with the geology - including age, stratigraphy and lithology - and vertebrate paleontology. The paper provides many new details about the Griman Creek Formation (GCF), a Cenomanian (mid-Cretaceous) formation which crops out in the area around Lightning Ridge. The GCF is a formation especially known for its diverse vertebrate paleo-ecosystem; of which many species are represented by quite a few opalised fossils The paper is also rather neat as it contains a nice overview of all the vertebrate groups represented at the GCF - an overview complete with a comprehensive (and up-to-date) list of vertebrate taxa, and several nice pictures of opalised vertebrate fossils Finally, the paper also indicates that a new ornithopod genus (Fostoria) from the GCF is soon going to be published Bell, P. R., Fanti, F., Hart, L. J., Milan, L. A., Craven, S. J., Brougham, T., & Smith, E. (2018). Revised geology, age, and vertebrate diversity of the dinosaur-bearing Griman Creek Formation (Cenomanian), Lightning Ridge, New South Wales, Australia. Palaeogeography, Palaeoclimatology, Palaeoecology. Abstract: The mid-Cretaceous Griman Creek Formation (GCF), which crops out near the town of Lightning Ridge in the Surat Basin of north-central New South Wales, Australia, is noteworthy for its opalised vertebrate fauna. The fossil assemblage comprises remains of aspidorhynchid teleosts, lamniform chondrichthyans, dipnoans, chelid and possible meiolaniform turtles, leptocleidid-like and possible elasmosaurid plesiosaurians, anhanguerian pterosaurs, titanosauriform sauropods, megaraptoran theropods, ankylosaurians, several forms of non-iguano- dontian and iguanodontian ornithopods, crocodylomorphs, enantiornithine birds, and stem and true mono- tremes, making it one of the most diverse mid-Cretaceous terrestrial vertebrate faunas in Australia. A detailed stratigraphic survey of twenty subterranean opal mines provides new information on the geology, age and pa- laeoenvironment of the main fossil-bearing beds. Vertebrate remains derive from the ‘Finch Clay facies’, lat- erally-extensive but discontinuous lenses of claystone that likely accumulated relatively rapidly in near-coastal but freshwater embayments (i.e. lagoonal conditions), and probably represent a single, roughly con- temporaneous fauna. U-Pb age dating of detrital zircons extracted from a distinct layer of volcanogenic claystone immediately overlying one of the opalised fossil-bearing layers yields a maximum depositional age of 100.2–96.6 Ma. These new dates confirm an early to mid-Cenomanian age for the fauna, rather than Albian, as has been reported previously. The GCF at Lightning Ridge is therefore equivalent to the middle part of the Winton Formation (Queensland) and several million years older than the sauropod-dominated fauna at Winton. For those who want the paper, PM me your email address and I'll send it to you -Christian
  17. Aboral view. Collected on C level. Adoral view. Collected on C level. It is from a different specimen due to matrix on the original and was added for identification purposes.
  18. I need help with this scale pattern. Snake or lizard? Cenomanian cretaceous
  19. On the surface this looks like a feather but i don't know if there are any plants that look like this. Here are the pics. Piece extracted from the cenomanian clay pits. Dated by argon from volcanic crystals on strata to cenomanian age late cretaceous.
  20. Goniopygus menardi (DESMAREST, 1825)

    Collected on D level. Matrix length: 14 cm. Test diameter: 2,5 cm. With some spines.
  21. Although lizards are prime material for fakers, i think this tail is authentic. It is an unusial cast fossil. Kind of like a ghost form. It seems that the tail became detached. Much like they do today. This is cenomanian age amber. From Myanmar kachin state.
