Another Ichthyosaur tooth from the lower Jurassic of Holzmaden / quarry Kromer. Its about 1.3 cm long and has a very nice root ! Some more pictures: -
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

My first Plesiosaur tooth with a length of 1 cm from the quarry Kromer in Holzmaden, Lower Jurassic. -
My daughter is totally obsessed with Ichthyosaurs at the moment and top of her Christmas list is a paddle. I’ve seen full articulated paddles worth thousands so I’ve been trying my best to manage expectations. This popped up on an auction site a little closer to budget so after negotiating a little discount I have snapped it up. It’s from the Posidonia Shale of Holzmaden, Germany (Jurassic) and has been identified as Temnodontosaurus and while I have no reason to doubt this I’d welcome your thoughts on it. My main query is regarding the tooth that can be seen among the paddle bones. Do

A 3.7 cm long Ichthyosaur vertebra from the Posidonia shale from the quarry Kromer near Holzmaden. Here two more pictures: And a bad picture of the unprepped vertebra: The stone was extremely hard so the prep work was very difficult.- 1 comment

A lovely 18" belemnite slab I've bought for my birthday (birthday belemnites are a bit of a tradition!). From the Jurassic Posidonienschiefer (Toarcian, Upper Lias) of Holzmaden - a very interesting and unusual selection of mostly the same species, one with a nice epirostrum. Not quite sure of the actual species, but it's close to Acrocoelites subtenuis and A. gracilis - neither of which usually have epirostra (the squashed bit at the tip of photo 2). It also contains a couple of bonus teeth including a Hybodus type which Sebastian @belemniten tells me is a rarity there. Ap

I've just purchased a fine slab of belemnites from Holzmaden and the stratigraphy is given as Posidonienschifer, Lias epsilon II-102. I know that epsilon is Lower Toarcian but please could anyone enlighten me about the II-102? I particularly want to correlate this accurately with Yorkshire, if possible! @belemniten ? EDIT: I've just checked the seller's other material and one that I'd expect to be from the same beds is given as "II-12" - so @oilshale is almost certainly right with his answer below, and it see

Hey everybody! I had an opportunity to visit the Holzmaden area (fantastic museum) and split some rocks at Schieferbruch Kromer in Germany. There were plenty of ammonites and I even managed a few neat belemnite pieces I'm very happy about. But one find has me a bit stumped. It appears to be very thin, and I have the feeling it is some part of an ammonite but I have no clue where it would fit in since it isn't very spirally. The caliper scale for reference is in mm and inches (it's about an inch long). The last 2 photos are at an angle to show some of the relief. If you've got any suggesti

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 extre

From the album: Holzmaden
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 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? A

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 will soon be visiting Holzmaden in Germany. Does anyone have any advice on how to find fossils there? (Which quarry to go to, where to look for fossils inside off the quarry, etc.) @belemniten @Ludwigia
