From the album: Fossils from the Plattenkalke of the Altmühl Valley
insect are not common in this region, they are not easy to be seen and to identify. A rare and hugh one is the water bug Mesobelostonum deperditum, this is around 3 cm© fossils worldwide

This is Aeger spinipes in "normal size", around 11 cm. Very often the antennae are not preserved or only in parts© fossils worldwide

this is the huge 18 cm Aeger spinipes I showed before as UV-Light-pic. You see..., its easier to prep with blue light© fossils worldwide

From the album: Fossils from the Plattenkalke of the Altmühl Valley
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

I bought this piece online and it just looks too good to be true, especially for the price.

From the album: Fossils from the Plattenkalke of the Altmühl Valley
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. -
Fossils Solnhofen, Germany. Need identification if possible
AnyArthropod posted a topic in Fossil ID
Hello everyone, I went to a fossil deposit in Solnhofen, Germany a few years ago. I never got all of my finds IDed however. I would appreciate your help if you have time. Thanks for your intrest, -AnyArthropod

Ammonite - Indeterminate species Jurassic, Tithonian Solnhofen Limestone, Altmuhltal Formation Bavaria, Germany -
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.

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.

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.

Rhizostomites admirandus Häckel, 1866 Upper Jurassic Lower Tithonian Solnhofen Germany -
Anaethalion has a strikingly spindle-shaped body and a large caudal fin that is deeply split with equally large lobes. The large dorsal fin is behind the middle of the body, the fish has a large anal fin. The pelvic fin is located slightly behind the middle of the body. It is a fast, small predator, which reaches body sizes up to about 20 cm.

Hello, my name is Schmirgele, collecting fossils since more than 50 years (yes, You can calculate my age over 50). Meanwhile my core collection consists of Bajoc and Bathonium Ammonites, added by a huge number of late jurassic fossils from Solnhofen limestone (rare sharks, other different fishes, crustaceae, insects). Thank You for beeing part of this community. By the way : end of January 2020 I will do a short stay in Chicago: is there any collector (jurassic ?) interested for a short meeting ? See You, Schmirgele

Pholidophorus macrocephalus Late Jurassic Solnhofen Bavaria Germany Length 32cm -
Diagnosis by Kietzmann & Bressan, 2019: Lumbricaria with elongate, bending strings showing overlapping of different parts throughout its length. Cylindrical cross-section. Locally, short segments can appear straight (based on the description emended by Janicke 1970). Lumbricaria is a trace fossil which is interpreted as the fossilized excrement (coprolite) of cephalopods. This trace genus (Ichnogenus) occurs in the Solnhofen plate limestones and various other similar plate lime occurrences. In the Solnhofen plate limestones, it belongs to the relatively frequent fossils.

New Upper Jurassic Thylacocephala species
oilshale posted a topic in Partners in Paleontology - Member Contributions to Science
I donated this Thylacocephala from the Upper Jurassic lithographic limestones of Solnhofen to Prof. Haug, LMU Munich. So far, three species of Thylacocephala have been described from the Altmühltal Formation (“Solnhofen lithographic limestones”),: Clausocaris lithographica, Dollocaris michelorum and Mayrocaris bucculata. Now a fourth new genus and species has been added: Falcatacaris bastelbergeri (Prof. Haug was so kind and named the species after me). https://bioone.org/journals/Palaeodiversity/volume-12/issue-1/pale.v12.a6/A-new-thylacocephalan-crustacean-from-the-Upper-Jurassic-lithographic-limestones/10.18476/pale.v12.a6.full?tab=ArticleLinkFigureTable
