It's nothing particularly exciting, but I just wanted to share what is possibly the prettiest looking Spinosauridae tooth I've ever seen. The enamel patterning on it is gorgeous, and very different to what I've come across on run-of-the-mill Spino teeth before. Both carinae and tip are also beautifully preserved. There is a pretty smooth enamel texture and no fluting, plus it's even sporting an offset, short mesial carina for an extra bit of personality. (51mm) Anyone else want to share their favourite colourful teeth?

I know specimens from the Kem Kem are some of the most common things found on the market, but with so much undescribed material, it's a favourite location of mine for finding those fossils that are just a bit odd and often overlooked. So here are some of my theropod teeth from the locality to date, that don't quite fit the usual Spinosaurid & Carcharodontosaurid profiles: To start with, a theropod indet. tooth with a very unusual profile, and unique (for the locality) mesial carina that ends naturally above the midline.

Genuine theropod dinosaur egg?
MohammadAAK posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello all, I saw one seller online listing this piece for auction. I'm interested in bidding but the fact the seller is from Taiwan worries me. Other than that, the egg looks nice. Seller says it might be a small tyrannosaurus or large therapod egg. Locality is noted as "East Asia", which I assume is china. And the description says this is from an old Chinese collection exported in the 80s. Cretaceous of East Asia. Best wishes -
Hi, does anyone know if theropod bones are completely hollow. I saw this for sale and was wondering whether it was theropod or just float because it wasn't fully hollow but had gaps and holes, the website wouldn't allow me to copy the image though.

So I've just added another new theropod tooth to the collection from the Kem Kem. I'm going to go out on a limb and say it's another contender for a potential dromaeosaurid tooth? • Very laterally compressed • "Pinched" to small degree at base • Mesial carina terminates well above the base • Slight twist to mesial carina • Mesial serration count (midline): 6 or 7 per 1mm • Distal serration count (midline): 3 or 4 per 1mm There are also interdental succuli present between distal denticles; not something I've particularly noticed on other dromaeosaurids, so I'm not sure if that has any impact on tentative ID? Lingual side?: Lateral side?: Cross section: Mesial face: Distal face: Pinch at base: Close-ups:

Would like to get some opinions on this kem kem tooth. It's just under 1.5", would be a hair longer but the tip is missing (faked with matrix). There are 4-5 serrations per mm on the mesial edge and about 2-3 serrations per mm on the distal edge. Opinions?

Hello, I have purchased this interesting fossil tooth from Kem Kem Beds, but I don´t know about the ID, it looks like Spinosaur or fish, but I´m not sure. Can you help me with the ID? The tooth is 1.1 inch (2,8cm) in lenght. Best regards!

Hi, There is this claw i have been looking at and i would like to know from the claw experts whether this looks genuine? The seller does state it has some fractures that have been glued and filled and the preservation plus the look of the overall shape leads me to believe that it is genuine. However most (or at least a decent amount of) large claws are probably fabricated to some extent and this claw is 10cm in length (4 inches). Part of the base of the claw looks to have a different colouration from one side so i don't if that is normal or not. Thanks in advance!

Hi all, I recently acquired this tooth labeled as Tyrannosaurid indet. It is 0.5 inch (1,27cm) in length and was found in the Judith River Fm, Wheatstone Co., Montana. The a-typical placement of the mesial carina led me to purchase it thinking it could be a Dromaeosaurus albertensis premaxillary tooth. Serration count over 5mm is 16 mesial and 15 distal. What do you guys think?

I found this theropod premaxillary tooth on my last day in North Dakota this past summer and since then I've wondered about what it is and if it had and diagnostic features of an particular theropod group. It's just over a centimeter long and has no serrations.

Who thinks this Wealden claw (my fossil) is Oviraptorid? What are the diagnostic features, anyone know....Henry?? Looks like it could be either to me - Dromaeosaurid/Oviraptorid. It is interesting that we also have maniraptoran confirmed at this locality, so this is another one to consider when identifying small elements like this. I am finding very small theropod dinosaur bones and claws that could belong to these animals. Currently Oviraptorids are only known from the late Cretaceous! And only in Asia. Yet some forum members have identified this as Oviraptorid...a big deal if they are correct....but are they?! The Wealden claw Dromaeosaurid claw Oviraptorid claw

Hi guys, I have recently acquired this tooth. It was sold as a Tyrannosauridae indet tooth from Bissekty Formation. I thought it could be Timurlengia, but i was not sure. From what I read, not much Timurlengia material has been found.. The tooth is about 2 inch long, and it is a little bit worn out. Its serrations are quite small. The serration density is about 12 denticles per 5mm. I am hoping someone can confirm the species for me?

I need some advice. I was able to obtain a nice 1.5 inch tarbo tooth that had been in a collection for over 15 years. It was obtained from someone who had direct access to the person who collected it in the field. As such, it was never prepped. I have it exactly as they found it w the dirt, matrix and even plant roots. Should I prep it or leave it “au naturale”. I kinda think it’s cool that way.

I've been browsing online, and come across this tooth. It's listed as Carch, but the serrations look completely wrong to me. The profile of the tooth doesn't particularly scream Carcharodontosaurid or Abelisaurid (though the distal margin does look quite straight) as far as I can judge. Any ideas, anyone? These are the best photos provided... Mesial margin: Distal margin: Distal denticles:
