  1. Steneosaurus tooth

    From the album Holzmaden

    A 2 cm long Steneosaurus tooth (crocodile) from the lower Jurassic from the quarry Kromer near Holzmaden (Germany). Sadly its a bit damaged. Another picture:
  2.  Saurorhynchus jaw

    From the album Holzmaden

    A 6 cm long Saurorhynchus jaw from the quarry Kromer in Holzmaden (Lower Jurassic, Posidonia Shale).
  3. Acrocoelites

    From the album Holzmaden

    This is a beautiful 15 cm long Acrocoelites (belemnite) from the lower Jurassic from the quarry Kromer near Holzmaden. Its special because of its great preservation and because it has an enlarged furrow, which was probably caused by an infection or a bite. One of my best belemnites until now! Two more pictures: The enlarged furrow:
  4. Here are two of my best belemnites I found this year in the quarry Kromer near Holzmaden (Lower Jurassic, Posidonia Shale) . I found tons of them this year but mostly they aren't that good preserved. The first one is about 15 cm long and is a relatively new find. I finished the prep yesterday. It's really good preserved and not too short. It should be Acrocoelites because I think I can see three apical furrows. Noticeable is that one of the apical furrows is really big. Maybe @TqB can tell a little bit more about this belmnite? And the second one is a 14 cm long belmnite with a crushed epirostrum. It could be Cuspiteuthis tubularis or a Acrocoelites inaequistriatus (thanks again for the ID Tarquin). Sorry the pictures are not the best but I thought some of you are more interested in seeing some invertebrate stuff from that quarry (normally I show the vertebrate material). Thanks for viewing
  5. Here is a piece with four paddle bones and another bone from a rather big Ichthyosaur. I found it about 2 weeks ago in the quarry Kromer near Holzmaden (Lower Jurassic) and finished the prep today. Overall I spent about 6 hours to prep this one. Especially because of the belemnites. The paddle bones are about 5 cm long. Sadly I forgot to take a picture of the unprepped stone but you could only see the cross sections of the bones on both. But here are some pictures of the progress: Finished: And some detailed pictures: I used air scribes and air abrasion to prep it.
  6. pterosaur bone

    From the album Holzmaden

    This is a 11 cm long pterosaur bone (maybe a flight phalanx) from the lower Jurassic from the quarry Kromer near Holzmaden. It was a very luck find as I found it on a stone, which I took with me because of another fossil. So I am very happy with this find although the preservation is not the best.... Two more pictures:
  7. pterosaur bones (perhaps Dorygnathus)

    From the album Holzmaden

    This is probably one of my best find so far from the quarry Kromer near Holzmaden. Its a plate with some pterosaur bones, which is very rare in Holzmaden as these are marine desposits. The bigger bone might be a Humerus. Before I was able to find this piece I only found a few isolated pterosaur bones. Hopefully I can find a complete one one day The prep of this specimen took about 5 hours. Before the prep it was visible that these are pterosaur bones so I was very surprised ... Some more pictures:
  8. Probably Plesiosaur bones

    From the album Holzmaden

    This seems to be a kinda rare find because maybe these are plesiosaur bones. Plesiosaur is the rarest marine reptile in the area of Holzmaden so I am pretty happy with this find On the plate are two ribs, a phalange and an interclavicle. But I am far away from being with the ID although I already showed it too some local experts. Its from the quarry Kromer near Holzmaden (Lower Jurassic, Posidonia Shale). Unprepped: Some more pictures of the prepped specimen:
  9. Crocodile cervical rib

    From the album Holzmaden

    This is a 5.2 cm long cervical rib of a crocodile. Its from the Posidonia Shale (Lower Jurassic) from the quarry Kromer near Holzmaden. Another picture:
  10. I wasnt very active recently so sorry for that. But the last weeks I was several times hunting for fossils in the quarry Kromer in Holzmaden (Germany) and in this thread I want to show you some things I found there. As some of you know may know I am mainly interested in marine reptile fossils so most of the finds are marine reptile bones and teeth ... So firstly some teeth. I actually found a lot of them but these are the best ones I found this year: A 2 cm long Steneosaurus tooth (crocodile): Another Steneosaur tooth with a length of 1,8 cm: And the last 1.2 Steneosaur tooth: I also found some Ichthyosaur teeth. Here is one of the nicest from this year: Besides of several teeth I also found some bones. Ichthyosaur bones are the most common type of bones there so I found mainly Ichthyosaur material. Especially I found many ribs but they are mostly not prepped yet. Here is just one little example: Its about 10 cm long. I didnt found many vertebrae this year but here is a pretty neat one with a length of about 3.5 cm: A bit rarer is this little Steneosaur (crocodile) vert: I am really happy that I can say that I found some pterosaur material this year. As these are marine deposits you may can imagine that pterosaur bones and teeth are very very rare. Here is a little 6 cm long and very worn pterosaur bone: Another pterosaur bone: This one is about 11 cm long. I didnt saw that one in the quarry Kromer but I took the stone with me because of a tooth on the other side of the stone so I was very pleased as I turned the stone around at home The next one is probably my favourite find of the year until now: These are also pterosaur bones (the big one might be a humerus?) Some more pictures of the same piece: And last but not least this find: I am actually not sure what it is. Might be pterosaur bone too ( maybe a Scapula?) or another possibility would be a bone from the skull but its kinda difficult to determine isolated bones ... Still many bones and teeth to prep and the year is still young so lets see what I can find/reveal! I hope you like some of my finds and thanks for watching
  11. Unidentified bone

    From the album Holzmaden

    This is an isolated, unidentified bone from the posidonia shale from the quarry Kromer near Holzmaden. Its very difficult to determine these isolated bones but it might be a part of a skull bone of a marine reptile ... Another picture:

  13. Steneosaur vertebra

    From the album Holzmaden

    A rare crocodile vertebra (Steneosaurus) from the lower Jurassic from the quarry Kromer near Holzmaden. Crocodile material is much in Holzmaden rarer than Ichthyosaur bones ... Some more pictures:
  14. I recently bought this piece from online and am uncertain of its authenticity. (But not very worried - it set me back less than $10!) It looks very much like the Dactylioceras ammonites coming out of the Posidonia Shale that I see online sometimes; however, up close, the shimmer appeared suspiciously similar to glitter nail polish. I tried a little acetone on one of the small back ammonites (third photo) and the gold dusting came off easily. There doesn't seem to be any depth to the positive fossils; where the plate is chipped, there just seems to be shale underneath. There are also tons of tiny ammonite impressions on the front but almost none in back. On the other hand, pieces like these are inexpensive, so would it be really worth the trouble to forge? Dimensions of the piece are about 13cm across, 1cm deep. Thank you for your expertise! I'm learning a lot from this forum. Happy to post more photos if necessary.
  15. Steneosaurus tooth

    From the album Holzmaden

    A 2 cm long Steneosaurus tooth (crocodile) from the lower Jurassic from the quarry Kromer near Holzmaden (Germany). Some more pictures:
  16. Ichthyosaur tooth

    From the album Holzmaden

    A 1.6 cm long Ichthyosaur (perhaps Temnodontosaurus) tooth from the lower Jurassic from the quarry Kromer near Holzmaden (Germany). The prep work was kinda hard because the tooth broke into two pieces. Some more pictures:
  17. Steneosaurus tooth

    From the album Holzmaden

    A 1.2 cm long Steneosaurus (crocodile) tooth from the lower Jurassic from the quarry Kromer near Holzmaden (Germany). Two more pictures:
  18. Crocodile vertebrae

    From the album Holzmaden

    These are two crocodile vertebrae from the lower Jurassic (Posidonia Shale) from the quarry Kromer near Holzmaden. The bigger one is about 8 cm long. Here is a picture of the unprepped fossil: The prep work took about 10 hours. I am very pleased with this find because in general crocodile bones are much rarer than Ichthyosaur bones in Holzmaden. Some more pictures:
  19. Ichthyosaur vertebra

    From the album Holzmaden

    A 2.5 cm long Ichthyosaur vertebra from the quarry Kromer near Holzmaden (Lower Jurassic, Posidonia Shale). Here is a picture of the unprepped cross section: It took about 3 hours to prep this one. Some more pictures:
  20. Steneosaurus tooth

    From the album Holzmaden

    A small and a bit damaged 1.2 cm long Steneosaurus (crocodile) tooth from the Posidonia Shale from the quarry Kromer near Holzmaden.
  21. Last Saturday I was in the quarry Kromer (Posidonia Shale, Lower Jurassic) for the first time of the year. Maybe some of you already noticed this topic: http://www.thefossilforum.com/index.php?/topic/93302-prepping-a-plate-with-some-ichthyosaur-vertebrae/ Beside of this plate I also found some other cool things but firstly here is a picture of the quarry: You are allowed to search in the heaps on the left behind the white car. The material isn't that bad at the moment. I was there about 6 hours and I found about 6 teeth. I already prepped three Stenosaurus (crocodile) teeth: 1 cm long: 1.8 cm long: (the best one) And 1.2 cm long: (damaged) I also found this fish: The cross section is about 5 cm long and it will need very much prep work... I don't think that I will do this one in the near future although a friend and expert said that this is a kinda nice find! My favourite finds were the bones. I found several incomplete ones which I didn't take home but also the plate with the vertebrae and another plate with some bones on it. Here is a picture of one of the visible bones: I think that should be an Ichthyosaur Humerus but I am not entire sure. I will post some more pictures of it tomorrow and after the prep. There are also a couple of ribs on the plate so it could be interesting! And for all the invertebrate fans. Here is a sweet little ammonite: Thanks for watching!!
  22. The quarry Kromer near Holzmaden did open two weeks ago (it was closed during winter). So last Saturday I was there the first time this year and I have to say that I am kinda satisfied with my finds! I found several marine reptile teeth, some mainly incomplete bones and a fish with much potential. In this topic I want to show how I prep/prepped a plate on which originally two Ichthyosaur verts were visible. The verts are all about 4 cm big. Here is a picture of the unprepped plate: (I have the other parts...) The prep work is very difficult because the stone is extremely hard. So I have to use my air pen to remove the stone directly above the verts and then I remove the remaining thin layer with my sandblaster with about 6 bar which is probably too much for the bones but otherwise I wouldnt do any progress ... This is the current situation: Until now I prepped about 4 hours and now you see that there are even more vertebrae on the plate At least 3 and a half.... And here is the one which wasnt visible at first. I damaged it a bit but I think its not too bad. Hopefully the stone is a bit softer around this one: I think I have to work many hours on it so wish me luck @LiamL
  23. Steneosaurus tooth

    From the album Holzmaden

    A very small (a bit less than 1 cm long) Steneosaurus (crocodile) tooth from the Posidonia Shale from the quarry Kromer near Holzmaden. Another picture:
  24. Steneosaurus tooth

    From the album Holzmaden

    A 1.8 cm long Steneosaurus (crocodile) tooth from the Posidonia Shale in the quarry Kromer near Holzmaden. The prep work took about 1 hour with my air pen and my sandblaster. Some more pictures:
  25. Recently I wasnt very active here but I managed to find a couple fossils in the meanwhile. A week ago I planned to visit the Pliensbach near Holzmaden in Germany. The Pliensbach is a type locality for the so called Pliensbachium, a time period in the lower Jurassic. On the way I saw an old pile with some jurassic rocks and stopped there. Luckily I was able to find some fossils there! Here is a picture of the view I had on the top of the pile: Belemnites are very common there but I found two really nice and big ones. Both are about 15 cm long and they seem to be Acrocoelites(?) ( @TqB ). They are one of my best belemnites until! I also found remains of a very rare layer with many sea urchins and sea urchin spines in it. Too bad I wasnt able to find some urchins but I found some cool plates with many spines. At the top of the pile I found some ammonites from the Sinemurian. I like the pyrite on them! The one I am holding is probably an Oxynoticeras and the other one is a Gagaticeras: Here is an overview: And one more detailed picture: Finally I found a piece of Loligosepia aalensis (vampyromorpha) and some fish rests. Here is a picture of the vampyromorpha: Alter my visit at the pile I was at the Pliensbach for a short time but I didn't really found something I can show. Maybe I will post one or two pictures tomorrow. Thanks for watching
