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.

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)

A 1.2 cm long Ichthyosaur caudal vertebra from the quarry Kromer in Holzmaden (Posidionia shale, Lower Jurassic). Some more pictures: The prep took about 1 hour and I used an air pen and a sandblasting machine. -
This piece was found by me two years ago in the Kromer Quarry near Holzmaden and was prepped by Roger Furze ( @Ludwigia ). On the piece you can see a disarticulated Ichthyosaur skull with some ribs and vertebrae. You can see one eyehole very good, although the eye itself isn't preserved. Isolated bones are not that rare in Holzmaden but such pieces are very rare! It could be a skull of a juvenile.

This fossil was found by me two years ago in the visitor quarry Kromer near Holzmaden and was prepped by Roger Furze ( @Ludwigia ). Thanks again On the piece you can see a disarticulated Ichthyosaur skull with some ribs and vertebrae. You can see one eyehole very good, although the eye itself isnt preserved. Isolated bones are not that rare in Holzmaden but such pieces are very rare ! At the maximum the piece is about 24 cm long. Unprepped: Prepped: The eyehole is very good visible: (Probably my favourite part ) The other eyehole: Some more bones: A vertebra: This one could be from a juvenile which is very rare! -

A 1.2 cm long Steneosaurs (crocodile) tooth from the quarry Kromer near Holzmaden (Lower Jurassic). Because the tooth is that filigree I didnt prep it further. Another image: -

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 bit damaged but nevertheless a nice Dactylioceras commune with a length of 14 cm. I found it in the quarry Kromer near Holzmaden (Lower Jurassic). -

A not so bad 1.5 cm long Steneosaurus tooth from the quarry Kromer near Holzmaden. The prep work was very hard because the tooth is quite fragile. Another picture: -
I was given that ammonite and the only information i have is it is from the lower jurassic, that it comes from north africa and that it could be a Dactyloceras. Each square is half a centimeter. What do you think ?

A 10 cm long unidentified bone from the lower Jurassic from Holzmaden. I think that its a part of a rib, but I am not sure. -
Now, i found this when i was seven or eight years old, on the cut down to the beach at Kilve in Somerset, South West England. It was buried in a band of blue/ grey clay in the Psiloceras planorbis zone of the Blue Lias , Lower Jurassic. Although i'd found many lovely fossils before this was my first exceptional, "WOW!" find. I still don't know what it is and that was 45 years ago. A colonial coral colony yes, but i don't think it can be Liassic? A derived fossil from the Devonian or Carboniferous seems likely, but which one? And it shows very little signs of having been transported huge distances, as it's quite a way to the nearest relevant outcrops of those ages. Here it is :

Hildoceras bifrons Ammonite SITE LOCATION: Somerset Shire, Great Britain TIME PERIOD: Lower Jurassic (170 Million Years Ago) Hildoceras is a genus of ammonite from the Jurassic era in the family Hildoceratidae. The shells are characterized by a narrow discoidal evolute shape, keeled venter, concave ribs along the outer flanks, and a shallow spiral goove running along smooth inner flanks. Whorls slightly overlap, cross sections are compressed. The ventral keel is bordered on either side by a shallow groove. The genus was named by Alpheus Hyatt after Saint Hilda in 1876. Hildoceras bifrons is an extinct species of ammonite in the family Hildoceratidae. It dates from about 175 million years ago in the Early Jurassic when it was both widespread and common. Fossils have been found in North Africa and Europe, including several regions of England. Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Order: †Ammonitida Family: †Hildoceratidae Genus: †Hildoceras Species: †bifrons
