Hi tff I can’t see this can be anything other than a pterosaur limb bone? when I first saw it I thought it may be a burrow, and checked in case there was a crustacean sat inside. early Cretaceous, bexhill uk, floodplain. About 20cm apologies photos aren’t great

Hello fossil lovers, I buy recently this partial (?upper) beak and this bone of a pterosaur (maybe a ?humerus). I need a confirmation of my identification and a help for a more precise id, to maybe determine the family or even better the specie.

I found this small bone (about 5cm) in marine cretaceous material from NW Queensland, it is very thin and fragile. It looks very different from the common turtle bones i usually find in this location .Anyone else have thoughts?I have added some close up photos of the structure the total bone thickness is only about 1mm in the middle. Is this possibly pterosaur?

How does one reliably differentiate Moroccan Pterosaur teeth from similarly elongated fish teeth? Are there any grooves, striations etc I should be looking out for under a loupe? (Image credit: AJ Plai, http://www.thefossilforum.com/index.php...)

Hi there, I’d like to get the expert opinion of you all. Could these be pterosaur ribs? i just know they’re from Whitney, Yorkshire. As you can see, they’re hollow, and all I know of, that would have little hollow ribs like that are pterosaurs, and avian dinosaurs, but I'd imagine it was very uncommon for articulated ribs from a raptor to make it to, and “survive” an aquatic deposit, intact and untouched, although I know pterosaur bones are sometimes found in aquatic fossil deposits, at least from coastal areas. I'm not sure what else would be found there with hollow ribs, and these also seem like maybe they’re too long for ribs of that size/width, so I'm at a total loss now, and wanted to ask for help in figuring out what these could be from. I'm also interested in what the large flat bone might be, and any others too, of course, if anyone can recognize what it/they might be.

Hello, I have been offered a Chinese pterosaur tooth--from Yixian Formation, Liaoning, China. There are a lot of toothed pterosaurs from there, so I guess narrowing down an actual species will be difficult. But I wish to make sure that it looks pterosaur rather than being something else. Unfortunately the matrix was split and reglued, so it has a repair down the middle. It is 2cm long. Seller is in Taiwan, so export of the fossil is ok.

Hello, any thoughts on this? It is sold as pterosaur remains--jaw pieces and a vertebra, from Ouled Abdoun Basin, Morocco. From the Cretaceous--unfortunately from an old German collection, so the information is limited. 240mm x 105mm Now, I think it is misidentified and is actually a bird--possibly Dasornis because on the first pic, the jaw has a long tooth and then a few of the smaller mini "teeth" which matches a drawing I found in a paper of similar birds, which I've also attached. If it's Dasornis or a bird, then that would mean it isn't Cretaceous in age? The preservation seems odd to me though---Most bird fossils I see from Ouled Abdoun, the bones are much lighter in color. Any thoughts would be great. Thanks

Extinct Gaits: How Did Pterosaurs and Synapsids Run?
Sightreader posted a topic in Questions & Answers
Howdy folks, me again with more silly beginner questions... I saw this video of a vampire bat running and wondered if pterosaurs - with their crutch-like folded wings - might have moved in a similar manner? Youtube: Vampire Bat on Treadmill I also saw this video of a Panda cub running. Might synapsids like Dinocephalians or Gorgonopsids - with those weird, “inturned” arms - have moved in a similar fashion? Youtube: Panda Bear Cub Running I’m guessing the answers to both of these questions is probably “no” - I would think that even a slight difference in a single joint or in the spine or hips would totally change an animal’s gait - but I really don’t know how the anatomy of such creatures compare. Are there extant species similar to either of these extinct animals that might give us an idea of how they moved? Thanks a ton for your patience! -
Good evening everyone, Does anyone have an explanation why there are so many theropod teeth from Kem Kem available (Carcharodontosaur, Spinosaur) while there aren't way as many herbivore teeth being offered from that area? Shouldn't herbivores have outnumbered the theropods by a lot?
-
Hello, many years ago a bought this small tooth in a shop, at the time they told me it was a dino tooth, that it came from kem kem, and the child me was happy. Now after all these years I clearly know that this isn't a dino tooth, but anyone can help me identifying it? Maybe it's croc or pterosaur

Professional fossil repair/restoration services?
Opabinia Blues posted a topic in Fossil Preparation
I’m currently in search of a fossil preparator who can repair/restore a broken pterosaur tooth. The other day I accidentally knocked a box of small fossils off of a shelf and several items broke. I’ve been able to glue most of the stuff back together with PaleoBond, with the exception of a ~2.5 cm pterosaur tooth (Kem Kem Beds, Morocco) that broke into two pieces, and the two piece don’t fit back together perfectly, Repair of the tooth would require filling relatively substantial cracks as well as painting. This is beyond my skill level, especially with such a small fossil, so I’m willing to pay someone with experience to restore to tooth, ideally so that the fact it was broken is barely noticeable. I’ve seen pretty convincing tooth composites from the Kem Kem Beds before, so I’m hopefully these results are attainable if done by a preparator with experience. Does anybody have any recommendations to who I could approach to perform such a repair? Or, better yet, does anyone reading this have any experience with this type of fossil repair/restoration? I apologize greatly if this type of post is not usual for this category, I know that it’s essentially an ISO ad. But I’ve tried Google looking for people who offer fossil repair services and had very little luck, and I know The Fossil Forum is full of experienced and knowledgeable people and thought this was my best bet for locating help. -
Hello! I have collected a large amount of material on marine reptiles. Origin - Cenomanian of Ukraine (phosphorite layer). After sorting through the material, I can offer 4 lots for trading. The first three are approximately the similar lots (small bones in phosphorites). 4th lot - also the bones of the Cenomanian, but mostly bony fish. If you are interested in such material, please contact me in PM. Have a nice evening -
Hello all, Here is a rooted pterosaur tooth from the kemkem. It's 6.5 cm long and is from the Kemkem. Does anyone know if an exact species can be determined for this tooth?

Any idea on this tooth, labelled as pterosaur? No bigger pics available because of its small size. It is sold as a pterosaur tooth from the Solnhofen formation. It is only 3mm in length---much smaller than other teeth I see there and smaller than the tooth I have from there. Most pterosaur from there seem to be curved, whereas this is quite straight, which makes me think it's probably not a pterosaur. It's a really tiny tooth---3mm. Even smaller than the Bull Canyon pterosaur teeth, could be from a rarer type of pterosaur there? Most are sold as Rhmphorhynchus, but I see there are a lot of pterosaurs from that location--incluiding the quite small pterodactylus and the tiny aerodactylus Thanks

Quite interested in this pterosaur humerus. It is described as Alcione -- From Morocco. The piece measures 16cm x 10cm The shape does seem to match another I saw posted here, but a more knowledgable view would be great. Many thanks

Any pterosaur experts able to ID an old Mongolian tooth? I've been looking into it and believe it could be Noripterus, going by the description of Noripterus been cone-shaped teeth and, the fish-based diet of Noripterus also fits conical teeth. It's an old collection tooth and seller doesn't have the formation, unfortunately, other than it being early cretaceous. I believe it might be from Tsagaantsav Formation which is one of the few formations I could find which fits the early Cretaceous age and has pterosaur remains found. Now, I personally haven't seen any teeth which resemble this one. The closest is Lyme Regis ichthyosaur, but I don't think Ichthyosaur has been found in Mongolia, I don't think it's a marine formation and there are no striations on the tooth. The base doesn't have a great photo, but it is oval in shape--matching the one pic I could find of Noripterus jaw. I haven't heard anything back from a couple I've emailed it too, except for one paleontologist who didn't recognise it. It's a very small tooth. 12mm in length. If someone is able to take a look, that would be great.

Help With A Privately Owned Opal Specimen!!
Australian Paleontology posted a topic in General Fossil Discussion
Hello everyone, after browsing the internet i came across a very interesting private opalised fossil collection (http://andrestucki.blogspot.com/). In this collection there is various fossil specimens, however it has most notably AN OPALISED PTEROSAUR SPECIMEN!!! This specimen is the most complete opalised pterosaur i have ever seen as it includes a fibula and tibia, tooth, partial skull fragments as well as a possible wing imprint and internal details in the fossils. This specimen is beyond beyond rare and as you could imagine is extremely scientifically valuable. As of now i am trying everything in my power to contact the owner but all i can do is leave comments on his posts. If anyone has any clue how to contact him directly or possible ways to, please please let me know!! Ps here is a video about only the Tibia And Fibula of the Specimen as well as a photograph, Thank you

Hi, Wanted to ask if these two wing bones on matrix are Pterosaur if anyone can help confirm? It is from the Ouled Abdoun Basin in Morocco (I don't know if it is from the Maastrichtian deposits) and I am a bit unsure if they are Pterosaur or bird. One bone is 33cm in length & the other larger one is 43cm in length. If they are Pterosaur, do they look like it could be from an Azhdarchid Pterosaur due to the size? Thanks.

Hello, I found this bone in the marine deposits of the Boulonnais, France. Upper Jurassic. I assumed it is a part of the jaw (snout) of a toothless ophthalmosaurus, which are abundant there (mainly vertebrae). However, this week I read the article about a toothless pterosaur jaw from the UK and saw some resemblance. https://www.bbc.com/news/uk-england-cambridgeshire-54891483 I added the pictures of the bone, the pterosaur and an ophthalmosaurus for comparison. I am curious about your thoughts. Regards, Niels

Hi all This may have been discussed before so let me know if it has but I was interested to know if anyone had read this paper: Frey, Eberhard & Martill, David & Buchy, M.-C. (2003). A new crested ornithocheirid from the Lower Cretaceous of northeastern Brazil and the unusual death of an unusual pterosaur. Geological Society, London, Special Publications. 217. 55-63. 10.1144/GSL.SP.2003.217.01.05. And what their opinions were on it? Was the pterosaur death directly linked to the leaf or was the leaf an added biproduct during the fossilisation process?

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.

Here is something from last week's virtual SVP conference... my colleague and I made the news, and not for our use of banned words. https://www.livescience.com/pterosaurs-walked-in-rain.html?fbclid=IwAR0fn9ovHHOHdCcuc0P0tdYJNi0E7D_KULlPv7ajP2KngC-Yc4LMHaJ3asg- 27 replies

I've been doing a lot of exploration in the Grayson Formation (Lower Cretaceous) exposures south of Waco lately, and so last week I was doing some hunting on a nice marly slope in the South Bosque River. I picked up lots of pyritized heteromorph ammonites and some turritella, but what really caught my eye was this tiny piece of fossilized bone. I know that vertebrate material can be found in the Grayson - I've even found some nice Cretolamna and Ptychodus teeth myself - but this doesn't seem to be fish or shark. The walls of the inner cavity are extremely thin when you look at the cross section where it is broken which is what's leading me in the pterosaur direction. Maybe a metatarsal? Or a fragment of a larger bone from a much smaller species? Any help would be appreciated.
