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 ...

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)

Yesterday i had time to hunt in Holzmaden. Some may realize that i posted this: http://www.thefossilforum.com/index.php?/topic/69842-last-hunt-in-holzmaden-for-this-year/#comment-732544 Now this is my real last hunt in the quarry Kromer in Holzmaden (Lower Jurassic) ... I worked hard about 3 hours, but i cant find much and the material there doesnt look good. So i only find this item: This tooth looks very special ... Its 0.7 cm long (after prep 1 cm long), so it was difficult to photograph the tooth. It looks very similar to this one or ? http://www.holzmadenfossilien.de/inhalte fossilien/Flugsaurierzahn_001.html Hope somebody can help me ... Thanks !

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

Hi.... Hope everyone is ok and finding some decent fossils.... I'm really struggling identifying what this could be found in lower Jurassic shales from the sinemurian Somerset coast.... It's such a distinct shape I would of thought it might ring a bell to someone.... I'm thinking a carapace segment or bony fish armour plates perhaps... Any help appreciated.... Thanks....

These are four Ichthyosaur paddle bones from the lower Jurassic from the quarry Kromer near Holzmaden. The prep was very difficult because the stone was kinda hard. I gave it up several times but now its finally finished. I hitted the bones a few times so its not the nicest piece. Maybe I will try to prep it from the other side one day. Some more pictures: -

These are four Ichthyosaur paddle bones and another Ichthyosaur bone from the lower Jurassic from the quarry Kromer near Holzmaden. The Ichthyosaur paddle bones are about 5 cm big so not too small. There are also a lot of belemnites on the plate. Because of them the prep work was kinda time intensive. It took about six hours to reveal everything. Here are some more pictures:-

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:-

Here is a little (about 1 cm long) Ichthyosaur tooth from the lower Jurassic from the quarry Kromer near Holzmaden (Germany). -
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

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.

This picture shows associated Ichthysaur bones from the quarry Kromer near Holzmaden (Lower Jurassic). It was found by me last year and was prepped by Roger (@Ludwigia). The prep work took about 10 hours. The associated vertebrae are around 13 cm long and at the maximum the piece is 20 cm long. Beside those vertebrae there are also Ichthyosaur ribs and Ichthyosaur paddle bones on the stone. Maybe it was a small Stenopterygius or a young one from another species. The vertebrae: The vertebrae and the ribs: The paddle bones: Some more detailed pictures: This piece is the best one in my collection until now and the vertebrate find of August 2017 !- 7 comments

Last Sunday I was able to find a piece with some jaw bones and teeth of an Ichthyosaur in the quarry Kromer near Holzmaden. I was very pleased with that find because the situation in the quarry is not the best. There is only a kinda small pile of stones where you are allowed to search (and where you can find marine reptile fossils, in the other regions of the quarry its very unlikely to find a bone or a teeth of a marine reptile). And this pile consists at the moment only out of very small rocks because they were laying until the beginning of the year there. So many collectors already searched there. And it's very likely that they don't get new material in this summer... Here is a bad picture of the quarry: And here are some pictures of the jaw bone with the teeth: The prep work took about 5 hours. It's a pity that I lost that missing part in the quarry. I searched about 1 hour for it but couldn't find it. But at that time I didn't know that its a jaw bone (no teeth were visible). Now about 65 small Ichthyosaur teeth are visible. They are from a very small Ichthyosaur, maybe even from a juvenile!

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:
