I have here a 3.3" Vertebra from the Kem Kem of Morocco, identified as Carcharodontosaurid. Before I buy it, I'd like to know how accurate that identification might be. I know how tricky verts can be to narrow down. I'm suspicious for that reason. Thank you, Bellamy

I recently bought this Dyrosaurus skull, it appears to be a juvenile. It has some nose damage and 4 teeth showing on each side. Not being an expert paleontologist but an amateur, I was thinking the teeth look a lot like mosasaur teeth. Are they related? Sue

Hi everyone, I have a theropod teeth that I need help identifying. This tooth first came from a reseller from Morocco in 2019 (before Talsint teeth flooded the market). He promises this came from a Boulmane digger, and calls it a Jurassic tooth. Irregardless of whether this is a Jurassic tooth or not, the reseller is reliable when it comes to locality I have tried identifying this tooth but all my best guess is that it's a Megalosauridae indet. Here are its info: CH: 26.1 mm CBL: 13.7 mm CBW: 8 mm Distal denticle count: 13/5mm on mid line Mesial denticle count: 17.5/5mm on mid line Unique trait 1: Well visible transverse undulations Unique trait 2: Mesial carina ends well above the cervix. Even accounting for the worn tip, it's half the length of the distal carina Unique trait 3: Distal denticles significantly larger than mesial ones (DSDI > 1.2) I read "The distribution of dental features in non-avian theropod dinosaurs: Taxonomic potential, degree of homoplasy, and major evolutionary trends" but I am still unable to confidently assign a theropod family to this tooth. The lack of locality data from Boulmane further hurts the ID. Here are some of the relevant pages I highlighted from the paper: Regarding denticle size: Regarding the mesial carina terminating above the cervix: Regarding the transverse undulations: A compilation of features about my tooth and the potential IDs for it: If you have any insight regarding my tooth, I would love to hear it. Thank you

I have here three vertebrae from the Kem Kem of Morocco sold as "Dinosaur or Crocodilian." Is there any way to identify which of these they belong to, and if so, can they be narrowed any further? Thank you, Bellamy First one is 1.5" long and 1.5" wide

I just recieved a box with a random assortment of Kem Kem fossils and I was wondering if some of you might help out with some of the ID's 1) A fish scute, Adrianaichthys (Lepidotes) pankowskii would be my guess. 2) Another Adrianaichthys (Lepidotes) pankowskii scale? 3) A small bone, turtle perhaps? 4) Crocodile osteoderm 5) Crocodile osteoderm 6) I often see similar fossil sold as Kem Kem coprolites 7) base of an Onchopristis numides rostrum tooth 8) A large fish vert, could it be Chondrichthyan like Onchopristis or probably just bony fish? 9) A fish vert? 10) Spinosaurid tooth

A year or so ago a friend of mine was moving to a new job, and he decided to downsize his collection and concentrate on his real interest, elasmobranchs (sharks/rays) and fish. As a result I inherited a number of fossils, including a Moroccan trilobite. It had a few cracks that had been crudely "repaired" with clay. Recently I decided to "restore" it, which means I removed the clay (toothbrush prep) and returned it to it's unaltered state. I initially thought it was one of the common Flexicalymene ouzregui but as I cleaned it up it looked a little bit different from that species, and also a bit familiar. I pulled up a paper (Destombes 1966) that @piranha posted here last year, and discovered that I actually had a Colpocoryphe grandis (Snajdr), a species I did not previously have in my collection. It is a decent size, 81 mm long by 41 mm wide across the free cheeks. Overall this species is similar to Flexicalymene ouzregui. The easiest to see character is the lack of pleural segments on the pygidium. The cephalon is also subtly different. Here is the figure from Destombes (1966) of Colpocoryphe grandis for comparison to my specimen:

Acadoparadoxides authenticity
Nanosaurus posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello All. I am curious as to the groups assessment as to the authenticity of this Acadoparadoxides specimen from Morocco. It measures roughly 13 inches in length (the fossil itself). I see restoration of the right eye (as in right side of the photo) and right portions of the glabella, but beyond that am fairly hopeful/comfortable that the specimen is authentic. It is interesting that an upper thoracic segment is missing, but I am thinking this could be taphonomic or that segment was lost when the rock split. Anyway, I value any thoughts and input. I'm happy to share more photos as well. Thank you.

https://www.moroccoworldnews.com/2021/02/335798/discovery-of-2-5-million-year-old-macaque-fossil-in-morocco/ The macaques, commonly known as the Barbary Ape, though they are monkeys, still live in Morocco's cedar forests and can also be found in Gibraltar, the only monkeys in Europe, allegedly taken there by the Moors during their invasion of Spain in the eighth century. Indeed the name Gibraltar derives from 'Jebel Tariq' or 'Tariq's Mountain' where the Moroccan fleet first put ashore in 711. Azrou, Morocco : Jebel Tariq :

Spinosaurus Restorations
BellamyBlake posted a topic in Is It Real? How to Recognize Fossil Fabrications
I have here a Spinosaurus tooth, 4" in length. It has the repair close to the base. I'd love to know if anyone can spot restorations. I don't see any. Thank you, Bellamy

I posted this one alongside a few other teeth, but it didn't get as much traction as I hoped. It's the one I was most curious about, and extremely unusual to me, so I figured posting it individually would be helpful. This is a Moroccan crocodile tooth from Kem Kem. It is serrated, and dagger-shaped, 1.02" long and 0.32" wide. Out of those I have consulted, Troodon proposed Hamadasuchus, though yielded that the dagger-shape is not consistent with those he had seen with those: I've essentially used all of my leads over these few days. If anyone has a different theory, I would appreciate anything to go on. Thank you, Bellamy

Is this trilobite real?... NOT!
Sjfriend posted a topic in Is It Real? How to Recognize Fossil Fabrications
Is this trilobite real? How often have we seen this question? Since folks are often asking I thought I'd toss in this obvious fake that I got in a bulk rock buy years ago. I'm no pro but I couldn't even find any real parts of this thing. I'll point out what I see and others can add their ideas Here is overall from top Here is closer shot of the front showing a few big problems. 1: the crack running around the side of the trilobite shows where the fake bug is separating from the base. They take a chunk of matrix, carve out a hole then glue on a molded fake. Then glue on powdered rock to cover the glue lines. 2: there are no details on this trilobite. They didn't even try to fake the eyes. The body is painted on. And here you can see the bubble holes from the resin / plaster used to mold the whole thing. And again, no detail what so ever. The fossil is very, very rough. No smooth lines, everything looks chisled in. Another thing to look at, when looking at the matrix overall, there is no repaired crack thru the matrix. These trilobites (like most Moroccan trilobites) are found by breaking chunks of rock looking for the black/brown lines of the trilobite shell. Then the rock is marked where the fossil is and glued back together. They then prep down to the trilobite. So, a repaired crack running thru the fossil is very common. Even though this is a bad fake I'm keeping it to use for showing what to look out for.

Dunkleosteus jaw: Is it real?
Praefectus posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello. I was wondering if I could get some opinions on the authenticity of this Dunkleosteus jaw. The jaw is coming from the Devonian of Morocco. It measures 12" long by 4" tall. The seller indicates that only the tip of the jaw was restored, but I suspect that the restoration may extend further. Thank you for your help. @Mioplosus_Lover24 Care to weigh in? Thanks..thumb.jpg.c41a054f903ffd14f1bde65c75e355fe.jpg)

I have here two teeth identified as Sarcosuchus sp. from Kem Kem, Morocco. They don't look like any Sarcosuchus teeth I've seen. Many here are more knowledgeable than I am about crocodiles. Based on these views, can they be identified as such? These are two different teeth. The first one is 4.2 cm long and nearly 2 cm across the base. The latter is 7 cm and 2.5 cm across the base. Thank you, Bellamy

Is this Fezouata hurdiid fake?
JUAN EMMANUEL posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello guys, so this specimen came up on the internet for sale. It is apparently a Aegirocassis benmoulai from the one and only Fezouata formation in the Draa Valley in Morocco. I am not trained with dealing with these types of specimens but what are the chances it is the real deal/thing??

Heyy, I have this part of a bone. It looks like the proximal half of a femur? It looks a bit to straight to be a femur of a crocodile, anyone agree? Does anyone know to look in what direction? Measurements: 80x29x21mm Kemkem beds Morocco. Gr Yasmin

I have this piece, crocodile?, which I think is a part of a vertebra?. It looks like the are zygapophyses visable and I think the grove should be the neuralcanal. But I am not sure, con someone shine a light on it? Measurements: 70x60x36mm Thank you

A new "T-Rex" tooth just showed up on our favorite site. It is not a Tyrannosaurus rex tooth however but a more common and far cheaper Carch tooth. We know this because of its more blade-like morphology, its slender profile, its shape, its smaller denticles and the sand on the base I already notice multiple bids on it and I have no doubt the price would escalate as many hopeful collectors would try their hands on getting a cheap T-Rex tooth for themselves. For anyone looking to buy a true T. rex tooth, there are several factors to take note of: 1) Thickness - T. rex had crushing teeth, hence the teeth are thick. They are meant to crunch through bone 2) Locality - T. rex teeth in the market commonly comes from the Hell Creek Formation and Lance Formation. These two formations are found in Montana, Dakota and Wyoming. If a tooth originates from Africa or Morocco, it cannot be a T. rex tooth 3) Price - T. rex teeth command a premium price. Even a small tooth an inch long may cost 500 USD or more. A 2.5 inch tooth would easily be 2k USD. While exceptions do occur, if a deal seems too good to be true, then you should be extremely wary 4) Source - Make sure you get your T. rex tooth from a reputable source. By that, I don't mean a seller with a high feedback score or someone who prints you a "cert of authenticity". I mean a seller who has a history of collecting or selling Hell Creek/Lance Formation material. Better yet, get it from someone who digs there 5) Morphology - Educate yourself on the differences between T. rex, Carch, Spino, Daspletosaurus and other large theropod teeth. That way, you can immediately spot inconsistencies such as serrations or colors that does not match a T. rex tooth 6) Cross section - If all else fails, look at the cross section. If the tooth has red sandy matrix or sand, it is most likely not T. rex but is more likely from Morocco Here, I will show an example of a red T. rex tooth that superficially resembles the Carch tooth above. Take a look at the thickness and cross section though and you would quickly realize both teeth have very different morphologies Getting an authentic T. rex tooth isn't cheap, nor will it be easy. But it will be worth it in the end when you finally obtain one. Good luck in your hunt and always feel free to ask TFF if you are unsure of an upcoming purchase

I have a 1" dagger-shaped tooth from the Kem Kem. I bought it as a crocodile tooth. The way it's shaped I assumed it was a fish fang, but the enamel looks pretty much like a crocodile's. Here are the only photographs I have access to for the time; is it identifiable? Thank you, Bellamy
