  1. 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!!
  2. 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
  3. Steneosaurus tooth

  4. 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:
  5. 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
  6. Ichtyosaur rib

    From the album Holzmaden

    A kinda interesting combination out of an ammonite, a belemnite and a partial Ichtyosaur rib. It wasn't very difficult to prep but all in all it took about 3 hours. The belemnite is about 10 cm long and the partial rib is about 11 cm long. I found this one last year in the quarry Kromer near Holzmaden. Some more pictures: And the unprepped rib:

  11. Ichthyosaur ribs

    From the album Holzmaden

    A stone with two ribs, a half vertebra and some rests of some belemnits from the quarry Kromer near Holzmaden (Lower Jurassic). All the bones are Ichthyosaur bones. The story of this one is kinda curious because on the stone was firstly only the damaged vertebra visible. But after a hit with my hammer I saw two cross sections, which belong to Ichthyosaur ribs: After some prep: And some pictures of the result: It was very tough to prep it because the stone is extremely hard and the separation layer between the fossil and stone was bad. I think all in all it took about 5 hours to finish this one. I am not completely satisfied with the result but its okay.
  12. Last Friday and last Sunday I visited the quarry Mistelgau in Bavaria. Its since 2005 abandoned and a very beautiful geotop. But you can still find fossils there! It's possible to find various Jurassic fossils like ammonites, gastropodes, marine reptile bones .... I was mainly interested in finding some Ichthyosaur bones and all in all I was quite successful. Here is a picture of the quarry: Belemnits can be found everywhere ... I found 6 Ichthyosaur vertebrae and 5 paddle bones. The vertebrae: The two associated vertebrae are my favourite ones. Unprepped: And prepped: The preparation wasn't too easy. It took 3 or 4 hours. Some more detailed pictures of vertebrae: Unprepped: Prepped:

  24. In this thread I wanna share some fossils from Holzmaden, which I found partly years ago but prepped recently with my new tools. I will not show only bones but also belemnites and other fossils from Holzmaden. All the finds are from the quarry Kromer. Hopefully I will be able to extend this thread step by step! So for today I want to show three bones from the posidionia shale from Holzmaden. Firstly this 3 cm long Ichthyosaur vertebra. Here is a picture of the unprepped piece: As you can see there was only the cross section visible so it was a kinda hard work. I think until now the prep took about 2 hours and I will probably prep it a bit more... but here is a picture of the current state of the vertebra: I am very satisfied with the result until now! Especially because I didn't lost too much of the fossil material in the areas where I had to glue it.
  25. Some bones from Mistelgau

    Recently I visited a clay pit near Mistelgau in Bavaria. It's a kinda famous quarry because of the "belemnite battle field". Huge plates with hundreds/thousands belemnites come from there. But you can also findother fossils like ammonites and also bones. I already was there a few times and I mainly found ammonites and of course belemnites. But this time I also found some bones in the area of the Belemnite battle field. They were just laying therebut it was kinda difficult to find them because they are round, Belemnites are round etc. so I more or less crawled through the quarry So here are two picture of the quarry: The typical ground there: Lots of belemnites, some ammonites and very rare other fossils like bones. I found two types of bones. Firstly Ichthyosaur paddle bones: Here is a picture of all the paddle bones I found (unprepped): Mostly they were kinda small but I was able to find a nice one with a length of 3 cm: And here is another detailed picture of a small one (1cm)
