Repair on carcharodontosaurus tooth?
Per Christian posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello all, I'm thinking of buying this carcharodontosaurus tooth, it's 78 mm long, but it looks a little restored in my unprofessional eyes. What do people here think?
-
Hi all. I have this tooth that i think is either an abelisaurid tooth or a carcharodontosaurus premax. Does anyone here have an idea which it could be? The tooth is a bit over 2 inches in length. It's from the Kemkem i think

Hi everybody Newbie from Belgium here. Been collecting, trading, swapping fossils for over a year now. Nice little amateur collection, bit of preparation-trails,... I've been wondering if there are specific techniques in the final preparation of teeth? Most of the high value teeth I see on *insert auctionsite* seem to have this shine/luster/gloss to them which makes them very pleasing to the eye. The photos of the Carcharodontosaurus-tooth show what I mean. I have about 10 of these (+7cm), but in no way as "shiny". Has there been any coatingproces to the original tooth to get this effect? Completely new to this specific field of knowledge - so I rather ask "the experts" on this forum.

Rooted carcharodontosaurus teeth
Fotsirk posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi . I got some rooted teeth. I heard they are harder to find because it means the dinosaur died. So are these good Thanks

Along with the debate on how many Spinosaurids are there in the Kem Kem we have a similar one on Carcharodontosaurids. Attached find paleontologist Andrea Cau blog on this subject. He analyzes the arguments brought by Ibrahim et al. (2020) and offers his rebuttal: http://theropoda.blogspot.com/2020/10/sauroniops-non-e-carcharodontosaurus.html His Conclusions "1) The front of Sauroniops is not 60% of that of Carcharodontosaurus , but of comparable size (and proportionately more stocky and broad, and both extend over 19 cm above the skull). 2) The position of the prefrontal facet of Sauroniops is not homologous to that of Carcharodontosaurus (anteromedial in the first, posterolateral in the second). 3) Sauroniops does not present diagnostic characters of Carcharodontosaurus at the level of the temporal fossa and the interorbital septum. 4) Carcharodontosaurus does not show the diagnostic character of the expanded dome at the level of the preorbital area, nor the deep separation of the nasal branches, diagnostic of Sauroniops . Therefore, there is no reason to consider the two taxa as synonyms ( contra Ibrahim et al. 2020)." Hopefully we will see something similar on Sigilmassasaurus from the authors with papers on this genus.

Repaired Carch tooth?
BonuFrailman posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone, I was looking around for carch teeth and this one caught my eye. It’s in rough shape but I don’t mind. Only issue is, to me the tooth looks like it has some glue and possibly composite on it. I want to know what you guys think so please let me know! Does it look like a low quality tooth, or a bad repair job? Tooth measures 4 inches long and comes from the Kem Kem Basin
-
hi, the tooth in question was found in the Kem Kem basin. the dealer sold it to me under the name Deltadromeus agilis. after looking at it, I am more of the opinion that it is a Carcharodontosaurus tooth. what do you all mean? (measures 5 cm) best regards
-
Hello ! i bought this tooth for quite a while for a very (i mean very very ) good price and i think this tooth may belong to baby carcharodontosaurus ? wound love to see you guy 's opinion ! kind regard.

The theropod landscape of the Kem Kem deposits continue to be more muddled with new discoveries and research but that should not surprise anyone. I've made several post about multiple Spinosaurid and Carcharodontosaurid in the Kem Kem and it continues to be supported by recent publications. The attached paper describes a femur that supports the concept that Abelisaurid's were in the Kem Kem. We are seeing teeth...so that's good. The paper however looks at the region: Figure 2 below, included in that paper, identifies the main theropod fauna of the region. The abbreviation KKCA under Morocco stands for Kem Kem Compound Assemblage. Please note that under KKCA there are two Spinosaurids mentioned Sigilmassasaurus and Spinosaurus indet. The paper concludes that there is to much ambiguity in the material studied to assign it to Spinosaurus aegyptiacus and further reevaluation is needed. Boy that sure puts an arrow through Ibrahim's Spino redesign. It also states that Kemkemia auditorei, paper attached, may be a crocodyliform or like the paper suggest a spinosaurid. The figure also shows two Carcharodontosaurid: Carcharodontosaurus and Sauroniops. Also Rugops is shown exclusive to Niger. More changes will come and hopfully in some lifetime we will have answers. So if you want to follow proper convention all Spino and Carch material should be identified has indeterminate but if you have that need to have a species name that's okay no one will know.

I have had this carcharodontosaurid tooth from the Kem Kem Beds of Morocco since Christmas 2011 and it is still among my most prized fossils. I took a photo of the cross section today and noticed that it's a rather fat tooth. There are other old pictures of it in my Gallery but does anyone know what tooth position such a fat Carch tooth could be? Premax, maxilla, dentary? The tooth is 7 centimeters long. Thanks in advance.

I had found this tooth for sale while looking in a antique mall in Virginia. The tooth appears to be in good condition, which is apparent due to the serrations still being present. And thanks to some members from this forum, it’s likely that the tooth was a tooth that would be set and ready to take a place of another tooth if it ever fell off. The tooth is also likely to have belonged to a younger animal, juvenile or sub adult is probably where the age is somewhere around.

Hi, I saw this large 8.9cm (3.5 inch) Kem Kem claw for sale. It is labelled as a Carcharodontosaurus (or Carcharodontosaurid) foot claw. I wanted to ask if the identification looks likely - i don't believe it is Spinosaurid and not sure of other large theropods the claw could be from. I should also ask if it looks genuine - the seller states that there are a few breaks but no restoration done on it. Thank you.

Hi all, I'm interested in finally purchasing some (theropod) dinosaur teeth for my collection. I'm just not sure where to start. I've been eyeing up some reasonably-priced stuff from a website. The material comes from the Kem-Kem beds in Morocco. Of course, I understand that going into the realm of dinosaur teeth (especially those from the Kem-Kem beds) and expecting any sort of accurate I.D. would be a poor idea. However, I'd at least like to know if they're even theropod teeth before I drop money on them. (Again, they are very reasonably priced.) There are a couple of items I'm considering: Labeled as "Abelisaur teeth" Labeled as "Carcharodontosaurus teeth" I can post more pics; the seller has a few for each. On one hand, the "carcharodontosaurus" stuff is better documented in the region which is always nice. However the "abelisaur" items are kind of in better shape. I guess my main questions are: Are they actually "dinosaurian" ? (I would be happy just being able to call them "theropod indet." but of course if the given labels are accurate that would be nice.) Would they be bad purchases? What would you purchase, if anything? I apologize in advance for my ignorance and I hope to learn something.

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 everyone!! I’ve just added a new tooth to my collection that puts my t rex tooth to shame and I wanted to get everyone’s opinion on if this is in fact a 5 inch carcharodontosaurus tooth? I’ve done some research and I’m kind of confident that it is. Kind Regards Dylan Macnish

So when I was taking a better look at my spinosaurus teeth I noticed that in the enamel part there are lines coming out from bottom to top, are these created by minerals or it was some kind of blood vessels or veins from when the animal was alive? Thanks.

Carcharodontosaurus tooth.
anastasis008 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I bought it from online that's why I'm a bit suspicious.

Going really basic here being new on the fossil game i wanted to know how a fossil gets created because i have read that the bone gets replaced by rock or sediments and they take its original form but if that's the case then we are not holding teeth, we are holding rocks in the form of teeth when holding a fossilized tooth for example. I don't really know so if someone could please explain to me if the fossil is actual tooth like it was back then or it becomes rock and the general process it would be much appreciated.
-
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.

Fake Carcharodontosaurus tooth
paulyb135 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Last year when I was still a rookie in the dinosaur tooth collecting hobby I acquired a rooted Carcharodontosaurus in a trade. I was advised shortly after receiving it by a few people that it looks pretty fake. I have only just got the time to look in to this properly and my findings astounded me! Attached is a before and after image. The root is completely fake and the crown is made up of at least two different carch teeth and then glued together and painted. I have now thrown this tooth in the bin. My advice for all collectors so they don’t make the same errors as me and others I’m sure is to get second and third opinions before buying or trading!

Hello! I received this claw today Do you know what dinosaur it can be? The seller assures that the claw is not restored. Foot claw and toe bone (posible from other dinosaur) from Kem Kem (Morocco) 0% restoration, ¿Carcharodontosaurus? Size: claw 6cm, bone 3,5cm Thank you so much!

Hello together, I am new to this forum and am starting to build my collection of dinosaur teeth. Because I want to do it properly, I am cataloguing the teeth I already own (unfortunately there aren't many yet). While taking pictures for my database I stumbled upon one tooth I bought two years ago on a fossil fair here in Germany. According to the seller it is supposed to be a Carcharodontosaurus sp. from the Kem Kem formation in Morocco. Bit it looks completely different from my second Carcharodontosaurus sp. I bought last year (picture 2) and which shows the classical serration. A first search for similar teeth on the internet remained without any results... So here is my hope that you can help my with the identification. Thanks in advance and please excuse my English...
