sometimes the best way to prepare Solnhofen-Fossils is to do it under blue light. This works perfect with nearly all crustaceans, vertebrate-fossils and some more. This one is fresh from the prep and needs finshing, huge Aeger spinipes (around 18 cm) from Eichstaett© fossils worldwide

the "Floating Crinoidd", Comaturella pinnata GOLDFUSS 1886. In the slab limestones you can find many free-swimming crinoids, Saccocoma pectinata. These are small and cover entire strata. Rare are other crinoids, such as this beautiful comatulid "Comaturella pinnata" with a height of over 13 cm. Comaturella lived suspended in the water column and could actively change direction. Complete specimens are rare© fossils worldwide

Fossil jellyfish are rarities. They are soft, consist almost only of water and have no substance that fossilises well. They are very rare in the Plattenkalken, but some have been found over the centuries. Even rarer than jellyfish are medusae. One of these specimens, which is rarer than a pterosaur, is shown here. An almost complete specimen of Hydrocraspedota mayri, about 18 cm in diameter. Found in Pfalzpaint© fossils worldwide

Manganese and Iron Dendrites
oilshale posted a fossil in *Pseudofossils ( Inorganic objects , markings, or impressions that resemble fossils.)
Dendrites are moss- or tree-like pseudofossils on the margins of rock fissures and fossils, usually on the bedding surfaces of platy limestones and sandstones. Mineral-rich water with high concentrations of iron and manganese has penetrated microscopic cavities between limestone layers, and diffusion-limited growth has created these brown iron and black manganese dendrites, which are often mistaken for fossil ferns or fossil moss.. This slab with manganese and iron dendrites comes from the lithographic limestones of Solnhofen. -
After my visit last week (http://www.thefossilforum.com/index.php?/topic/86063-my-little-trip-to-solnhofen/) This time I was at the visitor quarry in Solnhofen. It was very hard work and it was too hot but the finds arent too bad Its a pity that I couldnt find a fish but nevertheless I found some interesting things! Two pictures of the quarry: A beautiful 4 cm long Laevaptychus: A cuttlefish remain: with nice details (6 cm long): And my finds of the day: Two teeth Teeth arent that common in Solnhofen I assume, so I must had some serious luck The first one is 1.5 cm long and it seems to be a crocodile tooth. I think its a Steneosaurus tooth: I like the root The second isnt that big with a length of 0.7 cm. I cant determine this one... Maybe also a crocodile tooth? Maybe someone can help me a bit with determining? Thanks for your help! Hope you enjoyed the pictures!

To mark the occasion of this new sub forum for museums. I would like you show you some wonderful stuff in Teylers Museum in Haarlem, Netherlands. This is actually the oldest museum in the Netherlands and thus also has some really cool history attached to it and it's specimens. http://www.teylersmuseum.nl/en Besides fossils this museum also holds an art and science collection. The museum is just as beautiful as the specimens in it and a true time capsule. While it is quite a small museum, it's charm is worth the trip alone. Even the cabinets are pretty. It even has a few world firsts, such as Archaeopteryx and Mosasaurus. Now on to fossils! One of the most important specimens on display here is one of the Archaeopteryx specimens. This is actually the first Archaeopteryx as it was found before the feather and the London specimen were found. But for a long time it was labeled as a Pterodactylus. Only later was it found that it was in fact an Archaeopteryx. While very incomplete it is one of the larger animals of the genus (the third largest I think). the specimen consists of slab and counter slab. If you look close you can still see the vague impression of the flight feathers on the wings. It also very nicely shows the keratinous sheaths of the claws. Archaeopteryx lithographica Along with Archaeopteryx Teylers also has a very nice collection of the Jurassic of Solnhofen in Bavaria. They have a number of Rhamphorhynchus skeletons, lizards, fish, crustaceans and squids complete with tentacles and inksacs. Rhamphorhynchus Various fish Homocosaurus maximiliani Various critters

Taxonomy according to fossilworks.org. Diagnosis for the genus according to Bartram, 1977 (p. 140, excerpts): "Large, elongate macrosemiid fishes; skull roof free from ganoine; supratemporals greatly reduced; cephalic division of main lateral line and supratemporal commisure exposed by fenestrae; vomers bearing a transverse row of stout pointed teeth and a pair of large blunt teeth; ventral parts of anterior three infraorbitals expanded and overlapping the maxilla; gape very small, the quadrate articulation lying in front of the orbit ... dorsal fin single, extending from the occiput to the base of caudal fin, with between 32 and 39 rays each bearing denticles, leading ray proceeded by two basal fulcra, fringing fulcra absent; region immediately on either side of dorsal fin devoid of scales; scales rhomboid, secondary transverse rows intervening between primary rows above the lateral line, scales below lateral line forming a pattern of rectangles." Line drawing from Bartram, 1977, p. 141. Identified by oilshale using Bartram, 1977. Macrosemius is easily recognized among the fishes of Solnhofen by the continuous dorsal fin.

Caturidae non det. Upper Jurassic Tithonian (Malm zeta) Solnhofen Germany Length 33cm / 13" -
Crustaceans are a large, diverse group of anthropods which includes the crabs, prawns, lobsters, barnacles and other shelled animals. Perhaps owing to their hard shells and marine lifestyles, crustaceans have a rich and extensive fossil record, extending up to the Cambrian, though they do not appear in abundance until the Carboniferous. They make for attractive and familiar fossils, and are one of my favorite groups to collect. Allow me to present my humble collection.

The first pereiopod is strongly elongated, was used to catch prey, and was more calcified than the rest of the body. Mecochirus was probably a bottom-dwelling reef inhabitant. On the plate are also several specimens of the swimming crinoid Saccocoma tenella GOLDFUSS, 1831. Line drawing: References: C. E. Schweitzer, R. M. Feldmann, A. Garassino, H. Karasawa, and G.

I saw this tooth for sale recently, labeled as Pterosaur from Solnhofen, the tooth seems way too thick to be pterosaur, any thoughts? I'm thinking it might be fish, but I have no idea.

Emended species diagnosis from Grande & Bemis 1998, p. 493: "Amiopsis lepidota differs from other species of the genus by the following adult characters A through D (note there is a range of overlap between some species for characters B, C, and D). (A) The opercle is wider than in other species of the genus (0.96-1.00 compared to 0.77-0.83 in †A. woodwardi, 0.91-0.92 in †A. damoni, 0.82 in †A. dolloi, and an estimated 0.80 in †A. prisca, based on our study sample). (B) There are seven to nine procurrent epaxial caudal rays (versus five or six in †A. damoni, and three in †A. dolloi; the count in †A. prisca is unknown, and the count of †A. woodwardi is within the range of †A. lepidota). (C) There are 61-65 total centra and 48-52 total vertebrae in post-juvenile stages (versus 58-61 centra and 45-48 vertebrae in †A. woodwardi, 59-60 centra and 47 vertebrae in †A. damoni, 56-57 centra and 46 vertebrae in †A. dolloi, and 70-74 centra and 55-56 vertebrae in †A. prisca). (D) There are 17-19 dorsal proximal radials (versus 14-16 in †A. woodwardi, and 15-17 in †A. dolloi; †A. damoni and †A. prisca are within the range of †A. lepidota).

Hi all, I was playing with my poop a while back, as one does, and discovered a hidden treasure. I prepped out what I think is a nice little floating crinoid. It looks beefier than the Saccocoma in my collection. Can anyone verify that is what this is? Thanks a bunch!

Hello all My friend recently got this tooth from the famous Solnhofen Plattenkalk, and he really wants to know what the tooth belonged to. He is hoping for something like Archaeopteryx or Compsognathus. I personally don't think it belongs to either of those (although I love this tooth, it's very beautifel), but can't really tell which it is. I've heard everything ranging from dinosaur to fish for this one. Could any of you help? Specifics of the tooth: Size: 9mm Age: Thitonian (Late Jurassic) Seems to be unserrated Has some kind of 'ditch' similar to what you see on teeth of Acheroraptor temertyorum. These two pictures are all I have, got them from my friend and they are the same the seller used.
