I found this fossil in Gerstetten, Germany. It is late Jurassic, 145 million years old and was found in limestone. Does anybody know what it is?

Hello everyone! As my family was making its way through northern UT this summer on my way to Dinosaur National Monument I realized that there would be some extra time in the afternoon between when we would arrive in Vernal and when we would check into the hotel, so I decided to do the only logical thing and find a place to go fossil hunting for a few hours in the surrounding area. One of the sites I found only talked about finding belemnites, ammonoids and oyster shells on BLM land off of the highway going into vernal. It was supposed to be middle Jurassic Curtis formation (according to the geologic road signs, an interesting feature of this area's highways). I followed the directions given on the website and we reached the area that we believed to be the one mentioned (The Rockhounder: Belmemnite Fossils Near Vernal Utah) we met a young couple and their toddler out hunting for fossils (always nice to see). What we found somewhat disappointed me (however any afternoon spent fossil hunting is automatically better than any not doing so), only brachiopods and not one cephalopod fossil to be found. The main point of posting this in ID is to figure out if these brachiopods are jurassic species or older, as no belemnites were found they couldn't be used as indicators to the true age.

Dimensions: 185mm long Location: Atlas mountains Jurassic outcrops, Morocco I'm having trouble identifying this partial fossil bone. It's only smallish piece with some significant old broken sections but it still has a pretty distinctive blade-like shape and the internal structure visible at the end breaks is interesting. My amateur impression is that it's too straight for a rib, it's asymmetric so not a chevron, so I was thinking maybe a fibula, or perhaps an ischium or scapula. Any input welcome.

Hello, TFF I was recently in Holzmaden, Germany when I found a piece of an octopus. I also recently read a book about octopus intelligence. This made me wonder if some prehistoric creatures might have been intelligent. I am especially interested in tool use, which has been observed in some modern animals. ( Octopuses, Cetaceans, Birds.) Has anyone found some possibly intelligent animals(fossilized?)

This is an Afrovenator tooth from Marraba, Niger (Tiouraren Formation). The fossil is in rough shape, but rare. I’m still working developing an eye for noting the differences, but still difficult for me..Having trouble determining if it is indeed Afrovenator, Carcharodontosaurus sp. , or undescribed theropod. I tried comparing different teeth, but still have issues. Any opinion on this appreciated.

Greetings. I have a lot of photos I’d like to share and get some feedback on, assuming there is not a unanimous agreement that the specimens you see in this photo are purely Geological in origin... I found them, and many more, within the geographical boundaries of a Jurassic age rock formation in Northern California that is listed primarily as meta volcanic rocks. Considering that information, please tell me if you thinking I’m barking up an imaginary tree here... If you are uncertain, let me know, and I will post more pictures... Thanks for your time! -Quinn

Araucaria Leaves from Russia?
Zapsalis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello Fossil Forum, I found a supposed Araucaria fossil leaf from the Russian Federation for a very low price on our favorite site, eBay. The dealer claims that the fossil is an unknown Araucaria species from the Upper Jurassic of Lena River Basin, Markha River, Siberia, Russia. Is this fossil legit and should I buy it?

Carboniferous echinoid from a Jurassic limestone. Lovenechinus, UK
TqB posted a topic in Member Collections
Lovenechinus lacazei (Julien) (most likely this species but I'm not sure if there's really enough diagnostic detail). Lower Carboniferous, probably Tournaisian. Very rare anyway but of especial interest as it is from the Jurassic Doulting Stone (Bajocian, Inferior Oolite) of Somerset, UK. This is a limestone full of Carboniferous detritus, formed when the Jurassic sea was washing up against the Mendip Hills Carboniferous high ground. (Just acquired via a dealer from an old collection that included Carboniferous coral and crinoid fragments from the same location. No other echinoids though!) 2.3cm across

Recently acquired this very nice tooth from Morrison fm, Moffat County, Colorado. I think it is Marshosaurus, am I right? I am afraid to clean it right now because the tooth is very fragile. Total length is ~1.6 cm. Ruler is in inches, so 1 line=1/16 inch=~1.5 mm, so distal serration density looks to be around 4/mm; mesial carina seems to end at bottom ~3/4 of the tooth, as I understand, these are Megalosaurid characteristics. Although I couldn't find any info on other medium-small sized theropods, like Tanycolagreus, Coelurus or Ornitholestes. Thank you for help! @Troodon By the way, took those pictures with AmScope USB microscope, very useful tool for detailed teeth

A very informative journal from the Utah Geological Association that focuses on ornithischian dinosaurs from the Morrison Formation which form only about 15% of the dinosaur specimens recovered. What is key for those familar with this assemblage is that this article demonstrates that Nanosaurus agilis is the senior name for Drinker nisti, Othnielosaurus consors, and Othnielia rex. Four valid genera and six species are present: Fruitadens haagaroum, Nanosaurus agilis, Camptosaurus dispar, C. aphanoecetes, Dryosaurus altus, and D. elderae https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.researchgate.net/publication/327079773_A_photo_documentation_of_bipedal_ornithischian_dinosaurs_from_the_Upper_Jurassic_Morrison_Formation_USA&ved=2ahUKEwi3qsSK6JjuAhVCMH0KHYTRC_0QFjAAegQIARAB&usg=AOvVaw3-BCznH-EsvjYzvPuTZabh For tooth lovers
