An unusually complete specimen although crowns are well known from this location. It has a very short stem consisting of only six or seven columnals, all of which bear cirri. Once thought to be an early comatulid, it is now thought to belong to a separate lineage of nearly stemless pentacrinitids (Hess 2014). References: Simms, M.J. 1989. British Lower Jurassic Crinoids.

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.

Another small ( 1cm long) and bit damaged Ichthyosaur tooth from the quarry Kromer near Holzmaden (lower Jurassic) But the root is nice and well preserved ! Some more images: -
Yesterday I was again in the quarry Kromer near Holzmaden (Lower Jurassic) and I found a really nice tooth ! The tooth is about 2 cm long and 1 cm wide ! I think its one of the biggest tooth I have ever found ! Its a Temnodontosaurus tooth, which is a large Ichthyosaur. In the "Schlacke" (a specific layer) you can sometimes find smaller teeth but such big teeth in a good condition are very rare. I am really happy about this one Especially because there wasnt much material there, so it was a lucky find ! The prep took about 4 hours. - The quarry, where I find this teeth will close during winter so the tooth is also a great completion of this year !

A very nice Temnodontosaurus tooth from the quarry Kromer near Holzmaden (Lower Jurassic). Temnodontosaurus was a huge Ichthyosaur. The tooth is about 2 cm long and 1 cm wide. So its one of my biggest tooth from Holzmaden ! In the "Schlacke" (a specific layer) you can sometimes find smaller teeth but such big teeth in a good condition are very rare. Some more pictures: -
I went on a forage with @Barerootbonsai in the summer. We walked from Charmouth to Stonebarrow and found some great belemnites between Golden Cap and Stonebarrow Hill. They are from the Belemnite marls, Lower Jurassic ,Pliensbachian. I’m thinking there are two species here. Top two are the same and bottom one different. @TqB

A 0.7 cm long Steneosaurus from the quarry Kromer near Holzmaden (Lower Jurassic). The tip is a bit damaged. -
Last week I visited the quarry Kromer near Holzmaden (Lower Jurassic) for about 4 hours and I found many cool things ! Beside of some belemnits I also found some nice teeth. Mainly they are very small but this time I found a nice one. Its a Temnodontosaurus tooth, a large Ichthyosaur, which mainly hunted ammonites. The teeth had robust roots so that they could withstand the stresses of cracking shells without breaking off. The tooth is about 2.1 cm long and I am very happy about this one. In the past I also found some nice Temnodontosaurus teeth but such teeth in a good condition are very rare. You will maybe wonder now about the negative title but as you can see at the pictures the tooth isnt perfect. A part of the root is missing and the surface is a bit damaged. Here are some impressions: Thanks for viewing !

A beautiful and big (2.1 cm long) Temnodontosaurus tooth from the quarry Kromer in Holzmaden (Lower Jurassic). Temnodontosaurus is a very big Ichthyosaur, which mainly hunted ammonites. The teeth had robust roots so that they could withstand the stresses of cracking shells without breaking off. Such big teeth in a good condition are very rare in Holzmaden. Too bad that a part of the root is missing and that the surface is a bit damaged. Some more pictures: -

Yesterday a packet arrived at my place ... It doesnt look spectacular .... But it contains my prepped Ichtyosaur vertebrae ! About two weeks ago I sent Roger Furze (ludwigia) three Ichthyosaur vertebrae for preparation. And he really did a great job !! All of them are from Holzmaden (Lower Jurassic) and were found in the last or in this year. Enjoy: The first one is a very good preserved Ichthyosaur vertebra. Here is the unprepared condition: And here is it prepared: It is about 3 cm long and I found it last year in Holzmaden. There is a bit pyrite on it, which is very nice !

A beautiful and well preserved belemnite (Acrocoelites gracilis) from Dormettingen. Dormettingen is a city "near" Holzmaden, where you can also find fossils from the lower Jurassic. The belemnite is about 17 cm long ! It seems to have a small pathology on the tip. -

A small but well preserved Ichthyosaur tooth from Holzmaden (lower Jurassic). The tooth is about 0,6 cm long. Because of the small size its not sure that its an Ichthyosaur tooth. It could be also a fish tooth. From another angle: -
