A non-archaeopterygid avialan theropod from the Late Jurassic of southern Germany Exciting news from Munich and the famous Solnhofen area Everybody is familiar with Archaeopteryx, but according to a new paper published by the University in Munich, it had a brother who lived at the same time in the same area: Alcmonavis poeschli The Late Jurassic ‘Solnhofen Limestones’ are famous for their exceptionally preserved fossils, including the urvogel Archaeopteryx, which has played a pivotal role in the discussion of bird origins. Here we describe a new, non-archaeopterygid avialan from the Lower Tithonian Mörnsheim Formation of the Solnhofen Archipelago, Alcmonavis poeschli gen. et sp. nov. Represented by a right wing, Alcmonavis shows several derived characters, including a pronounced attachment for the pectoralis muscle, a pronounced tuberculum bicipitale radii, and a robust second manual digit, indicating that it is a more derived avialan than Archaeopteryx. Several modifications, especially in muscle attachments of muscles that in modern birds are related to the downstroke of the wing, indicate an increased adaptation of the forelimb for active flapping flight in the early evolution of birds. This discovery indicates higher avialan diversity in the Late Jurassic than previously recognized.

Pholidophorus sp. Late Jurassic Tithonian Solnhofen Germany -
Dear all Would be great if someone could help me with this Fossil. The seller told me that it‘s from Solnhofen, and it was for a long time in a private collection. The only similar fossil I found, is a Mesosaurus from Brazil... Thank you in advance!! Megadiente

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).

Found this small piece in Solnhofen. First thought it was just a fish bone but after prepping I don't know anymore. It has some structure on it that I have not seen before on fish bone although the material looks like fish bone. It is rather thin, just about 1 mm thick.

Hello everybody Here are some fish all directly from Solnhofen. I bought these many years ago at the local fossil store in Solnhofen. No idea about species, I just can assure these fish are all from there Looking for any Dino teeth material (except Spino and Abelisauridae from Morocco) or rooted Mosasaur teeth (maybe even with a small jaw fragment?). I can trade more fish for one tooth If you want these fish, but feel your tooth is worth more, maybe we can still make a deal. Let us talk about it Be aware that I live in Germany, however shipping to the US or other parts of the world is no problem. Will check this once I know the destination, because of the weight. I can provide more close up pictures, no problem My pocket rule only has CM, sorry! Fish 1 Fish 2 Fish 3 Fish 4 Fish 5

Hello everybody, so right now I'm on my holiday and today I was on a trip to Solnhofen/Bavaria. Most famous for its fossils from the Tethys Ocean during the Jurassic period. I won't post photos of the Museum since there is alread a Topic with good pictures. (But there will be pictures from the museums in Munich and Berlin next week by me). But anyway: You can go and hunt there for fossils by yourself. It's pritty easy to crack these Limestones and you can find lots of Ammonoidea there. I was with a group there and basically everybody found a little Ammonoidea or a part of it. But I got lucky and was the only one finding a fish. Well just the severed head of a fish. Length of the head is around 2 cm (= 0.79 in). In the Solnhofen Museum is a big fossil with lots of little Leptolepides sprattiformis. There where some Leptolepides with missing bodys as well. The explanation was, that a predator was eating the fish but left only the heads. Since the length would fit and Leptolepides where really really common in the area and time period my best guess is a Leptolepides indet. (I really can't tell the diffrence between the two species, since they both lived in the same area). But Orthogonikleithrus indet. is also a suitable candidate. They look similar. Hard to tell the difference since there is no body. Any help is welcome

So I was browsing through the Archaeopteryx lithographica records on FossilWorks; and in one of the three records (from Workerszell, Eichstätt), I notice the mention of an 'unclassified' reptile taxon "Rhacehosaurus gracilis". The only further information that was provided was the age range (150.8 to 145.5 Ma) and the geographical distribution. I looked elsewhere online (google scholar, ResearchGate...) for any other mention of the genus "Rhacehosaurus", and nothing else turns up. Do you people know about this enigmatic taxon? Is it some kind of invalid synonym or something? I'd love to know more about this..

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!

Last weekend I used my free time to visit two locations in the area of Solnhofen. Solnhofen is quite a famous fossil location, so many of you will probably know it. During the Late Jurassic, this area was an archipelago at the edge of the Tethys Sea and it preserves a rare assemblage of fossilized organisms. The most famous fossil from there is the Archaeopteryx. At the beginning I was very unsure if it really make sense to visit that location, because I often heard bad things like that its very hard to find something there . And I have to say that it was indeed very hard to find something but nonetheless I found a few fossils and it was much fun. I was firstly for about 3 hours in the visitor quarry Blumenberg. Here is the quarry: It makes sense to bring a shovel with you because you firstly have to put away all the debris before you can extract larger plates. The most common fossil there is the crinoid Saccocoma. Here are some examples: (about 2 cm big) Another very common fossil are coprolites from fishes/ammonites. They are called Lumbricaria: (3-4 cm long)

Caturus furcatus AGASSIZ, 1834 Upper Jurassic Schernfeld Bavaria Germany Length 18cm So far unprepped -
The Caturidae are represented in the Solnhofen Formation by at least four species: Caturus furcatus Agassiz 1834, Caturus giganteus Wagner, 1851, Caturus pachyurus Agassiz, 1833 (all from Solnhofen) and Caturus bellicianus Thiollière 1852 from Solnhofen, Germany and Cerin, France. The last two species were transferred to the revived sister genus Amblysemius (now Amblysemius pachyurus and Amblysemius bellicianus). C. furcatus was clearly a predator as evidenced by its mouth full of sharp teeth. It was a notable fast swimmer possessing an elongated, somewhat thickset body with slender head. Together with its only sister genus Amblysemius, Caturus was a member of the extinct Halecomorpha family Caturidae. It appears that the halecomorph Liodesmus, known from Solnhofen only, is related to the Caturids, rather than the Amiiforms, as has been usually surmised. Caturus possessed ganoid scales that are more cycloid in nature and as a member of the holosteans a bony skeleton with a partially ossified vertebral column. The head is short an equipped with powerfully toothed jaws. The dorsal fin is pointed and attached just posterior to the body's midpoint. anal fin is attached somewhat more to the rear. The caudal fin is large and deeply divided. Juvenile species.

So most of the Christmas decorations--at least the outside ones are down! and I got sidetracked again when I went into the garage to put the decorations away. Started to move fossil boxes around and found myself looking in the dang things...I was thinking some of this stuff needs to go in a case and started to photograph some of it and make sure the labels were with them. I've still got some work to do but thought I'd show you much of it...could be a few pieces on the other side of the garage but here's the bulk of what I have from Germany... This collection started many years ago and as I've never been there to collect personally my distant relatives immigrated from there and another good friend influenced me with her German collections so thru Gifts, trades and purchases here you go. Hoping there is something in here you havent seen before. File names have Genus and location. Some small vertebrates... An amphibian and similar sized small fish. Most of a dragonfly Some crustaceans from Solnhofen Some plants Some belemnites

Pleuropholis laevissima Agassiz, 1834 Upper Jurassic Tithonian Solnhofen Germany Unspectacular looking fish, but very rare. -
Juvenile Allothrissops salmoneus. In the lithographic limestone of Germany, there are two Allothrissops species: A. salmoneus from the Solnhofen lithgraphic limestones in Bavaria and A. mesogaster from the slightly older deposits in Nusplingen, Baden-Württemberg. The small dorsal fin is located behind the anal fin. Taxonomy from Fossilworks.org. References: Blainville, H. de (1818) Sur les ichthyolites ou les poissons fossiles.

From Wikipedia: "Members of the order are distinguished by possessing two dorsal fins, an anal fin, five gill slits, eyes without nicititating membranes, and a mouth extending behind the eyes. Also, unlike other sharks, they maintain a higher body temperature than the surrounding water".

Hi folks, i hope, this is the correct forum for this kind of issue.. A colleague from the german "steinkern-forum" asked me to share this topic. Last weekend, at the fossil fair in Leinfelden-Echterdingen, Germany (formerly know as petrefacta), a rare and precious fossil has been stolen. It´s a fossil fish (Turbomesodon relegans) from the jurassic of Solnhofen, it measures about 48 mm in length. If you see this fossil on ebay, a fossil fair or somewhere else, please send me a pm. If you're connected with facebook, please contact haufwerk.com Thanks, Nils
