  1. 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.
  2. Four Triassic teeth

    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
  3. 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
  4. Pterosaur claw?

    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.
  5. Unknown tooth from Morocco

    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?
  6. 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.
  7. 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.
  8. 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
  9. 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/
  10. For those of you that thought you had identified your Kem Kem pterosaur beak here is another one to consider. This paper describes the new species Apatorhamphus gyrostega which brings the number of named Kem Kem azhdarchids to three, and the number of named Kem Kem pterosaurs to five. More to come or do some of these Azhdarchids actually reflect sexual dimorphism time will tell. Just keep that eraser handy... Sorry once again its PAAAAAAAywalled https://www.sciencedirect.com/science/article/pii/S019566711930374X?via%3Dihub snip-it photos from the paper @msantix @LordTrilobite
  11. 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
  12. 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...
  13. Tooth or claw kem kem

    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
  14. 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.
  15. 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.

  17. Quite a while ago, I made a post talking about Kem Kem Pterosaurs, well since then I got more information, and new Information has been published. I specifically want to talk about Teeth. Now, the only toothed Pterosaurs we are aware off in Kem Kem are Ornithocheiraens, the clade that includes Ornithocheirids (not in all Versions though), Targaryendraconids, Cimoliopterids, Anhanguerids and Hamipterids. All of these besides Hamipterids and Cimoliopterids are possibly present in Kem Kem. So in my last post I claimed that the Teeth you can find should be labelled as Coloborhynchinae indet. based on the fact that Sirrocopteryx, and Coloborhynchus fluviferox are the only known Ornithicheiraens from Kem Kem, this was wrong. There are 5, or possibly 6 Taxa of Ornithocheiraen present in the Kem Kem Beds, I can only go into detail with 4. Sirrocopteryx: Now Sirrocopteryx is an interesting case, I have heard claims of it being an Anhanguerid, but as of now, I cant confidently say this to be true, so I will stay with the identification of it being a Coloborhynchine Ornithocheirid. Now, what Ornithocheirids have Teeth we can reference? Ferrodraco and Mythunga. (Image 1 in order) We can see roughly triangular very robust teeth in Mythunga, or rather long conical teeth that are still very robust. Image 2 is a Pterosaur Tooth which was sold on FossilEra, and it may most likely reflect Sirrocopteryx, but.... Coloborhynchus fluviferox: This is another Coloborhynchine from the Kem Kem Beds, it also is the largest Ornithocheiraen in Kem Kem, due to it's existence it's probably better to identify your Teeth of this Morphotype as Coloborhynchinae indet. Anhangueridae: Wellnhofer and Buffetaut, 1999 describe a very interesting Pterosaur tooth, "The teeth of morphotype IV are very ro- bust, large and recurved. In cross-section the teeth are rounded lingually, but flattened labially. A carina is de- veloped only along the posterior edge. The enamel pat- tern varies, but, in general, appears to be similar to the pattern of the other morphotypes. The surface of the enamel is smooth. The flattened labial surface of the den- tine is slightly wrinkled. The rounded surface of the lingual side is sculptured by fine, parallel, longitudinal striae and wrinkles. The length of the teeth preserved ranges from 28 to 39 mm." (Image 3) Wellnhofer claims these Teeth could be tentatively reffered to Anhanguera, but Anhangueridae indet. is preffered here. Targaryendraconidae: In (Pêgas et al. 2019) the Taxon Targaryendraco got described, which formed the basis of a new pterosaur family, Targaryendraconidae, in the same paper they describe "[...] are several isolated teeth that are elongate, striated, slightly recurved and elliptical in cross-section; including specimens from the Kem-Kem Beds, Cenomanian of Morocco" (Image 4) This is it, till the other new Taxa get published I cant say anything more, but I hope this post was useful to some.

  18. A couple of days ago a new Azhdarchid Pterosaur was described from Transylvania in Romania. Named Albadraco Tharmisensis, it is know from a couple of beak fragments and a cervical vertebra & the abstract is linked below with a picture of the fossils. https://www.sciencedirect.com/science/article/pii/S0195667119301016
  19. A new pterosaur-related paper is available online: Rodrigo V. Pêgas, Borja Holgado & Maria Eduarda C. Leal (2019). On Targaryendraco wiedenrothi gen. nov. (Pterodactyloidea, Pteranodontoidea, Lanceodontia) and recognition of a new cosmopolitan lineage of Cretaceous toothed pterodactyloids, Historical Biology, DOI: 10.1080/08912963.2019.1690482 Targaryendraco constitutes a distinct form of Anhanguera-like pterosaur, being united with Aetodactylus, Aussiedraco, Barbosania, Camposipterus, and Cimoliopterus in the new clade Targaryendraconia. It's quite ironic that Targaryendraco was originally assigned to Ornithocheirus based on comparisons with Lonchodectes compressirostris (formerly erroneously regarded by some as the type species of Ornithocheirus), because its holotype doesn't overlap with that of Ornithocheirus simus. The genus name is also tongue-twisting because it honors a fictional character from Game of Thrones. By the way, is there a copy of the Targaryendraco paper I could look at?
  20. Pteranodon wing display

    From the album Dinosaurs & flying reptiles

    Pteranodon Sp. Logan County, Kansas Niobrara form. Smokey Hill chalk Santonian-Campanian, late Cretaceous Im not exactly sure which bones they are, and I’d appreciate any input about it, but based on the significant difference between the 2 connecting bones, I’d imagine it’s one of the metacarpals and the connecting 1st phalanx. (I’m very proud of the display/storage box I made for it. Removed box innards and carved tightly fitted slots in padding from an old crystal wine glass box. Who says having random stuff sitting around for decades is a bad thing!?)

  25. Hi all, I was recently offered this tooth from late Cretaceous of Orensburg, Russia. Most likely Gaisky City District. I can't figure out if it's a Polycotylid plesiosaur or Pterosaur tooth. The overall shape is closer to pterosaur than plesiosaur. However, I am not aware of pterosaur having wrinkling like that, nor do I know of pterosaur teeth being found there. What are your thoughts on this? Thank you.
