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 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.

A small and a bit damaged 1.2 cm long Steneosaurus (crocodile) tooth from the Posidonia Shale from the quarry Kromer near 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!!

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

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

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:- 2 comments

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.- 2 comments

Formerly identified as D. punctatum. Quote from Thies et Hauff, 2011: "Specimens of Dapedium from the Posidonia Shale identified as D. punctatum by Q UENSTEDT (1858) were already suspected of not being conspecifi c with D. punctatum AGASSIZ, 1835 from the Lower Liassic (Sinemurian) of England by WAGNER as early as 1860."
