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

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: -

A tiny 10 cm long Ichthyosaur rib from the lower Jurassic of the quarry Kromer near Holzmaden. At first you could only see the cross section. The prep work took about 2 hours (I was slow ) One more picture: -

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: -

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: -

Last Sunday I was for about 6 hours in the quarry Kromer (Lower Jurassic) near Holzmaden (Germany) and I was kinda successful there. Besides several teeth I found a beautiful piece with croc bones. At first only a cross section of a bone was visible but during the preparation some more bones got visible. I am not finished yet but I prepped about 4 hours until now. This is a picture of the unprepped stone: And after 1.5 hours: I will post a picture of the current state today... I am very excited about this find because crocodile material is much rarer than Ichthyosaur material in Holzmaden. And I never found such a croc bone until now. I am really not sure what type of bone it is. Maybe from the pelvis or from the shoulder?

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.

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!!

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.

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: -
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

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: -

This is a kinda funny combination out of a fish bone and a very rare pterosaur bone. The fish bone is the bigger one (5 cm long) and is lying on the top of the pterosaur bone. The piece comes from the quarry Kromer near Holzmaden (Lower Jurassic). As these are marine deposits you can imagine how rare the pterosaur bone is Some very bad detailed pictures: (sorry for the bad quality but my camera is not good enough) -

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: -
