Unbelievable pterosaur diversity in this part of North Africa. This paper describes a unique small, long-beaked pterosaur from the Kem Kem Group of Morocco. Does not appear to be named. Paywalled https://www.sciencedirect.com/science/article/abs/pii/S0195667120303293

Saw this pair for sale, now they are sold as Alanqa but, I've seen some Alanqa beak fossils posted on here and they have a triangular shape to them, which makes me think these aren't Alanqa. Anyone able to help and let me know if they are pterosaur and/or which species they might be from, if it's possible to tell? Pictures -1 - 4 are of the first one. It is 1.5 inch Pictures 5 - 8 are of the 2nd is 1.1 inch Many thanks

Hello, Any thoughts on this? Sold as a pterosaur finger bone--repaired in two places. From Kem Kem basin. Seller describes it as being dense but lightweight. 10.3 cm long

Hello! I get this partial pterosaur beak from Kem Kem. Can it be from Alanqa? Thank you!

I recently purchased the two Kem Kem pterosaur teeth shown below. The seller identified both as "Siroccopteryx (Coloborhynchus) moroccensis", but I've learned by now that sellers will apply any remotely plausible name to help a fossil sell, even if it isn't scientifically justified. I read the pinned page on Kem Kem pterosaur ID, but am still confused about the exact species/genus ID of my teeth (if ID to that level is even possible for isolated Kem Kem pterosaur teeth). So: 1. Are these, in fact, both pterosaur teeth? My understanding is that pterosaur teeth are hollow and have enamel only on the tips. Both these teeth are hollow, and while the larger is missing enamel the smaller indeed has enamel only on its tip. These also do resemble photos of other Kem Kem pterosaur teeth online, though the larger is a bit unusual (though it matches the tooth in Figure 7b of the pinned article). 2. Do any of the experts here feel comfortable stating a genus for either tooth? Or do I just need to abandon my hope for ID of isolated reptile teeth to that taxonomic level? Any help is appreciated!

I have a couple riker boxes of a few dinosaur teeth. Nothing super high quality; I enjoy a variety of teeth and was on a budget so I never looked for the highest quality of teeth to buy. I'm happy with a nice representative sample of the animal. I've moved away from buying many specimens now as I'd rather go out and find my own at some point, but I bought these years ago and I'm very happy with the diversity they represent. Plus as I teach geology, they are great teaching specimens for the kids to. First up is my collection of Cretaceous North American teeth from Hell Creek, Lance, and Judith River Formations. Most are dinosaurs, though there are a couple other fauna represented here to. Probably one of my favorite teeth from this box is the acid etched raptor tooth. Though I do really like the JR tyrannosaur tooth as well (I watched that one sell for more than I could hope to purchase, but it was returned as it splintered during shipping. So I bought it as a short prep project for cheap. I never filled in the cracks as I prefer most things unrestored).

These caught my eye. First is Rhamphorhynchus from Solnhofen, Germany. 1cm. Edir: picture order keeps messing up. Its the thin, yellowish ond. 2nd is undetermined pterosaur from Mongolia. 12mm. Says from Monglei, chalk. Edit: picture order keeps messing up. Its the dark fat one. If someone can take a look, let me know what you think. Thanks

I have my doubts--aren't verts with the sort of ball-shaped end like this usually crocodile? It's been sold as a vertebra from Sirrocopterex. 3.5 cm in length. I'm suspecting croc, I'd love to be proved wrong though--a pterosaur vert would be a nice piece. Thanks for the help.

Hello, three teeth that I am interested in. If someone is able to check that they are as described, that would be super! 1st is a pterosaur tooth from the Dockum Group, Scurry County, Texas - 0.9cm 2nd - Dromaeosaurus - 1.1 cm from Judith River 3rd - Theropod from Bissekty Formation - 3/4 inch. Many thanks. It's the pterosaur tooth that most interests me. I don't have any from that formation.

I know where you can find me after lockdown . The delicate jaw fragment was collected by an amateur fossil hunter who spotted it while walking his dog at Sandown Bay, Isle of Wight.

Found these four, if someone can take a look. All from Bull Canyob. 1 - A preondactylus tooth. 5mm. Now, I know this is from Italy, so I'm guessing name is wrong. But is it pterosaur? 2 - Fabrosaurus. 3mm 3 - Prosauropod. 4mm 4 - Eudiomorphodon - 2mm. Another species I thought was from Italy. Many thanks

Hello everyone, So I’ve had an account for a little while now but haven’t done much yet and I never introduced myself so here goes. I’m Benton, amateur fossil enthusiast from around Seattle. My background so far is in archaeology and I’m currently working on my master’s degree in Human Evolution, but my primary passion is fossils and hopefully they will become my PhD. I study in the UK so most of my fossil collection comes from the Yorkshire coast, including my prised dinosaur footprint, but I have an ever-growing collection from everywhere I go and am learning to prepare some. My primary fossil passions are with early life of the Cambrian and Ediacaran (I’ll have to share my Burgess story soon) and pterosaurs, but this is by no means the full extent of my fascination. I also love fossil endocasts (but haven’t found one yet) and am hoping to study the brains of pterosaurs for my PhD. Some of my favourite specimens form my collection so far, The aforementioned dinosaur footprint A knightia mass mortality slab found last summer A hybodont shark spine from Aust which I hope to prep soon A small flower from Clarkia (my photo) which I don’t know the genus for yet Thank you all for having me and for your input into how to keep my rocks from falling apart. Benton

I've always been fascinated by the Cretaceous sea and its myriad of terrifying carnivores, many that would've made Jaws look meek. After watching BBC's Sea Monsters, I made it my goal to compile a box of sea monster fossils. I started this journey 10 years ago, and finally completed the box recently. Allow me to present my Predators of the Cretaceous Sea collection, and take you on a journey to the most dangerous sea of all times. The box measures 20.25 inches long. Inside are 24 unique predator fossils. I will introduce them from left to right, top to bottom: Rhombodus binkhorsti Age: 70.6 - 66 mya | late Cretaceous Formation: Severn Formation Locality: Bowie, Maryland, USA Size: 1 meters Diet: Molluscs and crustaceans art by Nobu Tamura --------------- Polyptychodon interruptus Age: 105.3 - 94.3 mya | Cretaceous Formation: Stoilensky Quarry stratigraphic unit Locality: Stary-Oskol, Belgorod Oblast, Russia Size: Maybe 7 meters (This is a tooth taxon so size is not confirmed) Diet: Anything it could catch Note: If you consider Polytychodon a nomen dubium, then this is a Pliosauridae indet. art by Mark Witton ----------------- Prognathodon giganteus Age: 70.6 - 66 mya | late Cretaceous Formation: Ouled Abdoun Basin Locality: Khouribga Phosphate Deposits, Morocco Size: 10-14 meters Diet: Everything art by SYSTEM(ZBrushCentral) --------------- Coloborhynchinae indet. Age: 99.7 - 94.3 mya | late Cretaceous Formation: Kem Kem Beds Locality: Southeast Morocco Size: 7 meters (high estimate) Diet: Fish and cephalopods

Hello, I saw this for sale labelled as Siroccopterex claw. But, a google search of similar claws shows up the usual curved claw shape. Is this just a different pterosaur claw than usual or something else? It looks familiar to me, I've seen similar before but cant think where.

I recently bought three teeth with the following description; Description Dinosaur Teeth - set of 3 - Spinosaurus, Deltadromeus & Siroccopteryx - 33×10×9 mm Cretaceous, Cenomanian, Kem Kem Fm. - Morocco Well preserved teeth of different dinosaur species: Spinosaurus maroccanus, Deltadromeus agilis and Siroccopteryx moroccoensis. No restoration, no reparation. Age: Cretaceous, Cenomanian, Kem Kem Fm. Locality: El Bega, Morocco Spinosaurus tooth size: 33 x 10 x 9 mm Deltadromeus tooth size: 16 x 7 x 3 mm Siroccopteryx tooth size: 12 x 3 x 2 mm Total weight: 5 g But I don’t have a lot of confidence in the ID, especially the ‘siroccopteryx’ It has been suggested that it may be a Pterosaur or even a fish. What are your thoughts?

For sale is a large bone (50cm or 20 inches) from the Ouled Abdoun Basin in Morocco (phosphate mines). It is listed as a Pterosaur wing bone and i think the id is correct, however i have seen bones from the Ouled Abdoun Basin that have appeared labelled as from the psuedotooth birds (generally Odontopteryx Gigas), and i am not sure how to tell the difference. The biggest problem is that the seller who purchased it from someone else, has the locality listed as the Kem Kem - which is certainly incorrect and because of the incorrect fossil site, i can't know for sure if the fossil came from the Maastrichtian layers of the Ouled Abdoun Basin and i believe the Pterosaurs described from these layers are known primarily from Couche 3. So i guess based on the pictures provided, does anyone familiar with fossils from the locality know if it likely to be Pterosaur. Thanks in advance.

I recently purchased a small lot of Bull Canyon Formation, New Mexico teeth, most of which were Phytosaurid. Then i noticed this tooth and how eerily similar it is too Pterosaur teeth from Morocco. From what i've read, there have been documented Eudimorphodon fossils collected from the Chinle Group, however i cannot find pictures for comparison. The closest teeth i can find from New Mexico are Preondactylus and Peteinosaurus teeth that have been put up for sale on multiple websites, though the information provided with them is unhelpful. I've included a photo of the "front", "back" and a side profile of the tooth. If clearer photos are needed to assist with identification, i can get some taken and uploaded.

Not sure if this has been discussed before on the forum but here is an article talking about a Pterosaur species named Ornithocheirus wiedenrothi that has recently been renamed in it's own genus as Targaryendraco wiedenrothi. The holotype fossils were originally found in Northern Germany back in 1984 but recently it has been concluded that this species belongs to it's own genus and as such the authors chose to name it in honour of the dragons in the book series "Game of Thrones". The Pterosaur itself lived about 130mya. https://www.theguardian.com/books/2020/feb/26/game-of-thrones-honoured-in-new-classification-of-pterosaur And the scientific paper can be found here https://www.tandfonline.com/doi/abs/10.1080/08912963.2019.1690482?scroll=top&needAccess=true&journalCode=ghbi20

Footprints of early Pterosaurs showed that they were good walkers
msantix posted a topic in Fossil News
An article describes some rare finds of non-pterodactyloid pterosaur footprints. It was thought that earlier Pterosaurs (long tailed Pterosaurs) were poor walkers since footprints of these early Pterosaurs were rarely found compared to some later Pterosaur. However these new discoveries have shown that the earlier Pterosaurs were quadruple and had five toes on their hind feet (compared to four for the later Pterosaurs), and the researchers believe that this is evidence that they were also good walkers and not clumsy on the ground. https://www.scientificamerican.com/article/footprint-find-could-be-a-holy-grail-of-pterosaur-research/- 2 replies

A new Azhdarchoid Pterosaur has been described from the Kem Kem Beds in Morocco. Unfortunately i can only link access to the abstract not the full paper. Anyway the new Pterosaur is named Apatorhamphus gyrostega and the researchers believe it to most likely be a Chaoyangopterid Pterosaur based on a partial rostrum. This is the third Azhdarchoid named from the Kem Kem (along with Alanqa & Xericeps). https://www.sciencedirect.com/science/article/pii/S019566711930374X?via%3Dihub

Likely Xericeps Pterosaur jaw fragment from the Kem Kem Beds
msantix posted a topic in Member Collections
Recently i asked an expert about a Pterosaur beak fragment i bought a couple of years ago (along with other Kem Kem bones) and i sort of assumed originally that it was a rare jaw fragment of Alanqa Saharica, but after asking i was told it most likely belong to Xericeps - the other described Azhdarchoid Pterosaur from the Kem Kem Beds. I wanted to show it because i think it is a cool piece that is worth showing and is basically a highlight of my collection. It isn't perfect and it isn't complete (it is 8.5cm long) but it is a nice fossil and one i am very happy to have! Who knows, maybe it might help anyone else in the identification of Kem Kem Pterosaur jaws. Here is the holotype jaw of Xericeps that i have been comparing the fossil to....thumb.jpg.08ee1b296755daf4ab44a9e22f770470.jpg)

Hello together, there is a type of fossil from kem kem I have seen several times now under different descriptions in the net: It is either called a pterosaur wing claw, or an undescribed pharyngeal fish tooth. At least to my eye they look like the same structure. The number of specimens lets me think its rather fish than pterosaur, but I´d like to hear your opinions please. Here is an example: Thanks, J

as a connoisseur of Pterosaurs, I wanted to ask the Community here to show me it's pterosaur fossils from the Kem Kem Formation. After seeing a rare Tapejarid Premaxilla recently get sold on a Fossil Dealing site (labeled incorrectly as Alanqa), I wondered what treasures could be present in Private Collections in this Community. Teeth are just as welcome as Bones are.

So, apparently I started an account on this site back in 2015 but never posted anything. Not sure why? I guess I was in college and working and didn't have time to post. Anyway. I'm here and definitely want to start posting about my own collection and whatnot. I am still and always have been into fossils and really anything science. Biology and comparative anatomy was my first love. I do have some questions about some of my fossils and want to share my enthusiasm for paleontology. Thanks

Teeth like this confuse me - i believe it is either a Plesiosaur or Pterosaur tooth (listed as Pterosaur from the seller) and it comes from the cretaceous sediments of Stariy Oskol, Belgorod region in Russia according to the description. It is 4cm in length. Any idea what this tooth most likely is? Thanks.
