Pterosaurs of the Kem Kem Beds, more than just Coloborhynchus and Alanqa.
Sassy PaleoNerd posted a topic in General Fossil Discussion
Pterosaur Fossils are a rarity, and few ever are on the public market, but the Pterosaurs from the Kem Kem Beds are seen most commonly on the market, this is rather not due to an unusally high Pterosaur abundance, but rather because almost every Fossil is being collected at this locality. Currently, there are 4 named species from the Kem Kem Beds, but the actual number is far higher. The Named Taxa are Alanqa saharica, Xericeps curvirostris, Sirrocopteryx morrocanus and Coloborhynchus fluviferox. Some unnamed ones im allowed to talk about are the Kem Kem Tapejarid, a small Chaoyangopterid species and a 3rd Ornithocheirid. The small Chaoyangopterid originally was identified as a Pteranodontid, but it is a Chaoyangopterid. There are up to 4 more Pterosaurs from this Locality, but I am not allowed to talk about them, all of them Azhdarchoids though. The 3rd Ornithocheirid wont affect the identification of any of the Ornithocheirid teeth, but that's all I can say. Sirrocopteryx and Coloborhynchus The Identification of Pterosaur Teeth from Kem Kem has recently become impossible to the genus level, for the most part that. C. fluviferox is a gigantic Ornithocheirid, and any Teeth of greater size might be referable to it, cf. Coloborhynchus fluviferox. Another thing notable is that the Identification can be restricted to a subfamily, Coloborhynchinae indet. instead of Ornithocheiridae/Anhangueridae indet., although this is rather Nitpicky. Alanqa and Xericeps Both of these Taxa are primarily known from Mandible and Rostral Tips, identification of these is rather easy, with the one of Alanqa being triangular in crossection, and the ones of Xericeps curving upward. Loads of Postcrania is also often refered the either of the two, referal is inconclusive though, especially considering there are more than just those two. The Chaoyangopterid and Tapejarid I have never seen either two on sale, but I will be mentioning them further too. The Tapejarid is a large Taxon related to Sinopterus, it's the first image. But there is more Material I cant mention. The small Chaoyangopterid is just a mandible fragment, but it has a rather deep crest. What about the Dsungaripterid? The Material of the Dsungaripterid most likely represents Xericeps. -
Croc jaw from Kemkem fabricated?
Abstraktum posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everybody So this fossil here bothers me for some time now because I'm still not sure what to make of it. I'm especially asking for the roots in the jaw and if they are a composite. Also this one tooth growing out of the root of the root looks odd to me. Is this a genuine fossil or are these roots / tooth put in the jaw? I'm used to these fake teeth put on jaws as a composite form Morocco but with this one I'm still not sure what am I looking at. On one side you can actually see the root in the jaw. Would something like this be fabricated as well? And is the ID correct? It's described as a partial maxillary of an Elosuchus sp. from the Ifezouane Formation, KemKem from Taouz/Morocco. No word about any restoration/fabrication or what so ever. Size is 3.48 in (8,84 cm). -
Hello, This is my latest acquisition. A tooth of carcharodontosaurus sp (impossible to certify that it is saharicus I think?). How do you find it? Is it a nice piece ? There is a lot of restoration or red flag ? Thanks !
-
Hello, so I was thinking about buying this piece but i would love it if I could remove the matrix from it to make it look better. Is this possible? Thanks-

Hello, so i was thinking about buying this tooth, what do you think of it? is it real? Thanks. -
Carcharodontosaurus tooth.

I bought it from online that's why I'm a bit suspicious. -
Baltic amber and spinosaurus tooth.
anastasis008 posted a topic in Is It Real? How to Recognize Fossil Fabrications
So I recently got this Baltic amber and I found out that there is a test that includes water and salt and if the amber sinks then it's fake but if it floats, it's real and mine sank but I'm not sure could you please examine it yourself? And also the spino tooth if you can. Thanks -
Hello so could someone please explain the situation with sigilmassasaurus and spinosaurus was it the same dinosaur? was sigilmassasaurus bigger? Thanks

So i have a small fossil collection and i want to learn how to study teeth and their anatomy the teeth i already have are from spinosaurus, mosasaur, carcharodontosaurus and megalodon if anyone could help me learn how to do it i would be really thankful. Thanks.
-
So having a small fossil collection i have thought of the possibility of studying the fossils especially the dinosaur teeth but the problem is im not a scientist so i don't know how to study them so if someone could tell me if cheap fossils like these could be studied and how it would be largely appreciated. (Collection includes 2 spinosaurus teeth, a meg tooth, 2 mosasaur teeth, mammoth hair, carcharodontosaurus tooth) Thanks.

So after following nizaar ibrahim's study in 2014 I learned that spinosaurus walked on four legs and it spend a lot of time in water being a good swimmer. But recently I saw that some new studies have been published and then some others and I have lost track so if someone could please inform me about the latest discoveries and tell me if spinosaurus was a good swimmer and if he walked on four it would be much appreciated.

Hey y'all, I have some part, probably, Mawsonia. I think the third thing in the top is an angular. The last thing, i think, is the top part of a skull but not from mawsonia but another fish like. Can someone tell me if I am looking in the right direction? Oh, the distance between the 4 linea is 1 cm each. Thank you

Hello everybody This here is my little story about bad fabrications and red flags and what to make the most of it. I got my hands on a 8 cm (3.15 in) Carcharodontosaurid indet. tooth from KemKem. It all started with the breaking of the tip while handling the tooth. It fell out of my hand on the table. Maybe just 3-4 cm falling, but that was enough to break the tip. I asked Matt ( @Haravex ) what to do with it and he suggested to use super glue but also mentioned the hight amount of bad glue and other junk on the tooth. His idea was to work with Acetone and see what is real and what is just junk attached to the tooth. And oh boy this tooth was REALLY bad... This was after a first cleaning with Acentone... you already see the unrelated stuff way better, especially at the tip. So I threw the whole tooth in Acetone for several hours. Then it started to really fall apart. Here you can see the glue between the pieces. It was really bad and so much glue all over it and in between. After a night in Acetone here are the pieces I could recover. They are now without any glue, matrix or other stuff. The tip definetly doesn't belong to the tooth, because off the different color. And this was the bottom, I big pile of glue and god knows what other stuff.... After a lot of puzzeling I managed to restore most of the bottom. So this is the final result. No glue, no matrix, no junk, no unrelated bone/tooth parts. I used very very strong super glue. Only a few tiny drops where enough to hold it together. Glue is only in between the pieces and not on the surface. As the tip definetly doesn't belong to this tooth I decieded to not attach it. This is the actual tooth measuring at around 6,3 cm (2.48 in). Again a BIG thank you to Matt @Haravex for helping me with this tooth. Without him this would not be possible. It was the first time I actually restored a fossil and for what it is I'm pritty happy. I learned at lot about fabrications and red flags with this tooth. Way more than you could ever learn from just reading online. In the end you have to make your own experiences with this. See this stuff with your own eyes and work with the material. In the future I will know now better on what to look for.

i got this fossil recently on a fossil fair and to me it kin da looks like a piece of jawbone. there are however no teeth or tooth sockets visible. personally i was thinking maybe sauropod or pterosaur. anyway here are some pictures. please let me know what you guys think!

Hello ! I received 2 dinosaur teeth, from Kem Kem (cenomanian or albian). We can not accurately identify the species (if it is possible to identify them?). We think of a species of Abelisauridae, or maybe Dromaeosaurid (Deltadromeus agili?) (For the smallest)? Ideas? Teeth one (smallest): Second teeth :

I've bee looking around at different vertebrae but cannot seem to find a match any ideas? A rough guide in the right direction as to what it looks like it could be from? ventral to dorsal measurment are 12mm anterior to posterior is 15mm and lateral left to right side is 21mm Thanks in advance.

Listed as dinosaur vert from Kem Kem Beds...is it dinosaur or reptile? If it is dinosaur, can it be narrowed down to theropod, etc.? Thanks
-
Hi, I am looking at this bone from the kem kem and i was wondering how do you tell the difference between a theropod bone and a crocodilian bone?. The bone is hollow but only a bit (the hollow part still has matrix in it), does the morphology of this bone suggest theropod? Thanks.

This tooth was picked up on fieldwork in Morocco in a mining village called Begaa. So it's provenance is certain. It is very very strange. I have shown it to many experts in the field, and all have come back with 'i don't know'. The root-crown boundary is just at the start of the orange discolouration. I am thinking crocodile or sauropod? But any input or ideas would be great! It is not fabricated in anyway. I have soaked it in acetone and looked at it down a microscope to see any joins... there aren't any! And it's completely free of matrix. So it is definitely real... just really frickin' weird! each square = 2mm, so specimen is about ~2mm in height

Hello to everybody! I'm kinda new here, but before I start I must say I really love this forum! It has really great vibes and you instantly can tell that this is a good and friendly community! So, I am ziggycardon, I live in Belgium, close to the border of the Netherlands and when we start speaking geologically, I live on the same cretaceous sediments as where the first major Mosasaurus discoveries where done! Unfortunatly I have never been on a fossil hunt myself and everything currently in my collection was bought or given to me. But I hope to change that soon, as I am dying to go hunting myself. Maybe the Chalk sediments 3 km from my home would be a good place to start! For the rest, my job, my major hobby and my other main interest besides fossils are living animals. I currently work as the head of terrarium & aquarium in 3 different pet stores and I have quite a collection of reptiles, amphibians, invertebrates and tropic fish myself. In my spare time I often take my own living animals along with my fossils and other educational natural history material to schools so I can teach kids about nature and it's history and hidden mechanics. For the rest are my other hobbies mainly based around movies and televisions as I collect a lot of stuff drom my favorite franchises like "Lord or the Rings" & "The Hobbit", "Game of Thrones, "Pirates of the Caribbean", ... And I also attent a lot of comic cons and other events related to those franchises. But then this topic! In this topic I will show my collection of fossils (and also minerals, stones and meteorites) as it is right now and then I will highlight each group of fossils bit by bit. I am currently starting with a own specialized fossil room, so ofcourse the progress and end result will also be posted here! And ofcourse when something get's added to my collection, I'll show it here as well. Sometimes a photo of my "special" pets or taxidermy specimens might pop up, but this topic will mainly be about the fossil room and my fossil collection. For the rest, if you have any comments or questions about the collection or about me or about anything, feel free to ask! I'd love to reply!

More Moroccan ID Listing Help
Masp posted a topic in Is It Real? How to Recognize Fossil Fabrications
Some more Moroccan fossil listings. Wondering if any are worth looking into. Trying to properly ID. #1 Partial unidentified dino limb bone or Croc? -
So far I have only 2 Spinosaurus teeth in my collection. Their not very impressive by the fact that they’re small with lots of feeding wear on their tips. Hopefully, I can collect more impressive specimens in the future. I added a drawing of the animal to give you a sense of what it looks like. This drawing is also on my Deviantart gallery. One thing I have is that the tooth on the left feels to me more crocodilian like in appearance.
