  1. I just find some time to post some other finds from my last tour ... Besides this: http://www.thefossilforum.com/index.php?/topic/72771-new-finds-from-mistelgau/#comment-766199 http://www.thefossilforum.com/index.php?/topic/72434-a-very-beautiful-quarry I was also in a quarry near Buttenheim (at the same day). As many of you know its a very famous quarry where you can find nice white ammonites (mostly Pleuroceras) from the lower Jurassic. I didnt spend much time there so my finds arent spectacular ... Here are some of them: The smaller ones: I think nearly all of them are Pleuroceras sp. ... And some detailed pictures: A nice 5 cm big one: Another smaller one (3 cm): A nice 6 cm big spinal
  2. After this post: http://www.thefossilforum.com/index.php?/topic/72434-a-very-beautiful-quarry/#comment-762636 I want to show you other finds from the same day but from another quarry ! After my visit in Ludwag i spend two hours in a quarry near Mistelgau. I already posted a hunt there a while ago: http://www.thefossilforum.com/index.php?/topic/69816-a-visit-in-mistelgau/#comment-732319 Sorry but i dont have in-situ pictures (it was simply too dark). However the quarry didnt change a lot I mostly found again small ammonites which come from the "Jurensismergel formation", so about 182.7 Ma till 174.1 Ma (Toarcian). Here is a picture of all finds: (Not spectacular ) Some detailed pictures of those ammonites: A nice 3.5 cm long Pleydellia sp.: Another Pleydellia from another perspective : The biggest one with a length of 5 cm: (Cotteswoldia ?) Two medium sized (3 cm) ammonites with a nice preservation. I think they are also Cotteswoldia ... And i want to show another nice find: This nice gastropod is one of the best Costatrochus i have found until now ! Its 1.5 cm long and well preserved .... Thanks for viewing ! Hope you enjoy

    Insect non det. Middle Jurassic Daohugou Nei Mongol China
  9. Hello! i have found this rock laying on the surface of a dry saharian river. It is a dark blue hard limestone with some fossils in it. This facies is known here as between upper oxfordian and lower Kimmerijian. I think it's a kind of coral. Is it really? i have put some "vaseline codex" on the rock to make it more bright. Sorry for my poor english. Site: Laghouat, Algeria, north africa.
  10. This coprolite is from a marine creature that swam in the Jurassic seas that once covered this parts of England. The dark inclusions that can be seen on the surface are cephalopod hooks. In April 2016, the University of Minnesota X-ray Computed Tomography Lab scanned the specimen using a X5000 high resolution microCT system with a twin head 225 kV x-ray source and a Dexela area detector (3073 x 3889 pixels). Many of the images shown here are of individual 3D elements/features within the coprolite that were separated/isolated using Blob3D. Aside from the hooks, it is hard to definitively identify the inclusions without damage to the coprolite. Imagery is available for study through the University of Minnesota.

    This is a brief video showing inclusion contained with in a Jurassic marine coprolite thanks to the magic of X-ray computed tomography (aka Micro CT Scan). The coprolite is from the Oxford Clay Formation, Orton Pit, Peterborough, Cambridgeshire, England. Imagery was provided by the University of Minnesota X-ray Computed Tomography Lab.
  13. Hi Apologies if I'm going about this in the wrong way. We found this today at Ogmore beach in the Vale of Glamorgan (UK) which is part of the Jurassic coast. We've been able to identify most of what we found, but this one has stumped us. Any help appreciated.
  14. Hi again, Posting this as it's also very unusual for round these here parts.. Size is 3 inches approx Nearby there are Caloceras Johnstoni Ammonites (a term i picked up from this article here on the forum thank you Seth) Can anyone help out with an id i only have one photo atm All the best in your quests Ben
  15. What do you think of this allosaurus tooth with root ?
  16. Hi all, Location: West Somerset Coast. Length approx 4 inches. Geology is Blue Lias but i was so far out to sea that it may be late triassic 0_o We've had very low tides here of late which have stripped the mud layer and have been exploring the revealed rock beds found a full bed of devils toenails, alongside modern day oysters.. Also found this, which is not like anything encountered down there before. Sorry in advance for the poor images, the specimen remains in situ.. What interests me is (all of it!) .. the apparent uniformity and the small circular depression in the middle at the bottom. ps the geology in the area was subject to considerable tectonic activity during the period of formation Can anyone help? All the best in your quests Ben
  17. Hello everyone, Last year I have found a fossil tooth, which I (at first) thought could be an interesting shark tooth fossil - since shark teeth are very abundant in this locality. It is just about 10 mm long, but as I looked at it later, I thought that it must be marine reptile fossil. At home I took my micro-camera and took some detailed photos with some small maginification. Then I was sure it is not a shark tooth. but something else. I have discussed this finding with Daniel Madzia and his answer was that it possibly belongs to Plesiosauria sp., Ichthyosaurus or Crocodylomorpha. He is teropod expert though and suggested me to ask someone who is into marine reptiles. Could you please help me with identification ? Thank you very much. Lenght: 10mm. Unevenly striated, slightly curved, cone-shaped. Circular cross-section. Age: upper jurassic, oxfordian Site: Brno Hády quarry (Moravia, Czech republic, central Europe)

  19. Hi all! For the holidays, I am enjoying a nice relaxation at my grandparents house in Middelburg (NL). We were planning on hunting at Kaloot for sharkteeth and seashells, unfortunately the bad weather prevented it . My grandma, being a sculptor (Hanneke Beaumont, if you're interested in sculpture you might know her), brought me to her atelier today for me to make something myself. I had already made a few things a few years back, so the material wasn't very new to me. 1) an Euoplocephalus in its habitat 2) an Acrocanthosaurus resting its head on a tree (because its head is too heavy ) Today, I wanted to make something new, so I decided, after a bit of brainstorming, to make a re-creation of what Lyme Regis (UK) looked like 200 million years ago, basing my idea on the fossils from the Blue Lias formation found there (ammonites, belemnites, coral, fish, marine reptiles, etc). I am using this picture for ideas on the background. I am nowhere near finished, as for now I have only worked on it for one morning. I am planning on finishing it though as quickly as possible. This is what I have done till now: Sorry for it being wet, but I had to make it wet so that it wouldn't dry up immediately. The big lumps are meant to represent rocks on the seafloor, and the tubes plus the othe thing are meant to be coral. In the middle lies an ammonite shell half-buried in the sand. Detail on the ammonite: Detail on the corals: I am going to add still a small Dapedium fish, a big ammonite and a big belemnite, then add a few more small details. I will return this afternoon and tomorrow morning, and will of course keep you updated of the progress! I hope the end result will be good! Best regards, Max
