Original Carcharodontosaurus teeth?
Marco90 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I'm trying to expand my collection by buying a tooth of Carcharodontosaurus (or rather of Carcharodontosauridae, as far as I understand it is impossible to understand the species with 100% accuracy). So I'm inspecting some sites of reputable and trustworthy sellers, but still I'm always afraid of finding heavily reworked or restored teeth. I'm not convinced by the root: authentic? completely artificial? restored?

Hi everyone! I recently acquired this very large Mosasaur tooth and was hoping to get some help with two questions. The first is help with a species ID since it seems a lot of these are being IDed as this new species (thalassotitan) that was only discovered like a year ago I think? The second is what is going on in that root? There seems to be another Mosasaur tooth AND a Cretolamna shark tooth imbedded within the root. There's still some matrix around the fossils within the root which seems to have a very large cavity that shouldn't be there, so my hypothesis is that the root was broken and while lying on the sea floor matrix and other teeth gathered in the cavity. Either that or someone threw one heck of a party there 70 million years ago and things just got nuts. As usual though with something this weird I'm hoping for a second opinion. Tooth is from the Oled Abdoun Basin Moroccan phosphates. The entire specimen measures about 14.5 cm tall. The crown is 5.142 cm tall and 3.465 cm by 2.788 cm at its base. distal carinae seems to be lightly serrated. So what do you all think? Any insight is appreciated as always!

Hi guys, do you reckon these are all Carinodens or are there a few globidens mixed in? Thanks @Praefectus @pachy-pleuro-whatnot-odon 1. 2. 3. 4. 5. 6.

What kind of dinosaur belongs to this teeth?
Cris Tang posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi. Another seller sent me pictures of Morocco teeth. But I have no idea of the left one. Do you have any idea about it? The seller said he doesn’t know the information of it also. I think it’s probably a Carcharodonsaurus teeth. But I’m not really sure about it. So I would like to ask your opinion. Thank you so much

Hi everyone! I bought a batch of fossils from Tegana Formation, in Morocco. Among the fossils there are those reptile teeth: The seller assures that the five in the top row are Spinosaurus aegyptiacus (or at least Spinosaurid species). The three in the bottom row are reported as Elosuchus cherifiensis. The seller is reliable, however I noticed that the teeth are all very similar to each other. Is there a possibility that they all belong to the Spinosaurus or Elosuchus species? Is there any way to tell the two types of teeth apart? Below I put a few photos of the individual teeth.

Hi guys, wondering if any of these teeth are from carinodens (they are from a seller online so I don’t have more pics) thanks @pachy-pleuro-whatnot-odon

Found this in one of those shark & mosasaur tooth bags from Morocco Looks like it could be bone to me, not sure what is up with the hole in it though.

Good day to all ! I was recently offered (by a Moroccan dealer) 2 heteromorphic ammonites at reasonable prices, and would appreciate any input. Both are around 40cm ( 16 in) in total length, and the details on their proversum, flexus and retroversum seem rather convincing. (see the 1st and 2nd photo) What appeared suspicious are the following: - the 2 ammonites are of non typical colorations (this is due to protective coatings per the vendor) - their remaining matrix seemed too smooth and flat, resembling that of a confirmed plaster casting made in a French museum (see the 3rd photo) It is claimed by the vendor that these Ancyloceras were found in broken pieces and glued back, but were mostly 'originals'. Only their spirals were restored/reconstructed. Similar Ancyloceras Sps from the lower Aptian plurimetric clayey formation of east Paris basin in France are known to be extremely rare (Bersac, 2020), but I have no idea how common these are in similar formations of Morocco. Again, thanks for any input ! reference: https://www.sciencedirect.com/science/article/pii/S0753396919300497 Bersac, 2020

Hi guys I’ve got a few more mosasaur teeth here I think this is the last few! Thanks again for your help @Praefectus @pachy-pleuro-whatnot-odon 1. This one’s in a bit of jaw bone, the striations aren’t so pronounced but maybe still gavialimimus 2. a more posterior or pterygoid gavialimimus? 3. yet another one! This one is a bit more angular though 4. reminds me more of a croc tooth actually!

Hi guys got a few more for idenitification thanks for your help 1. this was broken in shipment and is completely hollow even the root is this normal? The rounded cross section makes me think T.atrox 2. slightly more compressed, eramiasaurus? 3. gavialiminus? 4. another gavialiminus, any idea why both of these are so compressed? Preservation?

Hi guys got a few more mosasaur teeth with unconfirmed identities 1. slightly pathological M,beaugi ? 2. faceted, eramiasaurus?

Hello everyone! I'm here seeking for help with the ID of this Mosasaurus jaw section I recently bought. It comes from Ouled Abdoun, Morocco. I don't know much more, and I'm just becoming crazy reading that there are more than 18 Mosasaurus species from Morocco The seller didn't commented on the ID, but he said it may be an Eremiasaurus. What do you think? Also, do you think that the bone on the bottom left is the left side of the jaw? Thanks in advance!

Tooth of a mosasaur.

This was in a lot of El Mers fossils, but the Moroccan dealer was not sure what this was. It may not be anything, but just in case it's something unusual. It's about 2.6 cm (1.02 inch) in length Boulahfa, Boulemane, Morocco.

I recently picked up 5 Lamniformes teeth from the Kem Kem Beds. 3 are easy ID’s, Leptostyrax. There are 2 that I need a little help with. First one is 2.1 cm. I know both Cenocarcharias and Haimirichia are known from the Kem Kem beds. I have no examples of either in my collection. I didn’t find a lot of examples of Haimirichia so I can really pin it down.

I recently purchased this trilobite for cheap at a local show, genus was named Cephalocrytalus and I didn’t think much of it. However, after doing some research, I cannot find any actual genus of trilobite of this name. Is it possible to track down the true identity of this guy? The vendor claimed it was from Mt. Issimour, Morocco, and is approximately 3” long.

Carcharodontosaur tooth restored?
JorisVV posted a topic in Is It Real? How to Recognize Fossil Fabrications
Came across this supposedly original carcharodontosaur tooth. Claims it is original and I really have my doubts. Only have one picture though. This is not a tooth I bought or anything. Just came across, nothing more

Hola, necesito ayuda para poder determinar la especie de este fósil, procede del sur de Marruecos y está encajado en una pieza de 155cmx 113cm, sabemos que petenece a la familia Mosasauridae pero tenemos dudas con respecto al género y si es un adulto o una cría. (Translation added and post moved...) Hello, I would appreciate your help to identify a fossil, it comes from southern Morocco and is embedded in a bed of clay, its measurements are 155cmx113. We've been told it's a Mosasaurus, but we have some doubts about the genus.

what do you think? Never seen before, a spinosaur-tooth from morocco with unusual structure (grooves), where do this come from? We have seen hundrets or thousands of this teeth from morocco but this is the first one with this structure. Preservation is good, has perhaps a pathology (crown not symmetric) I can do better pics if necessary, did them tonight with my iphone in the cellar after recognizing this grooves so, tooth is "in prep"

Guide to Help Purchase Rooted Moroccan Theropod Teeth
Troodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
We very often see collectors asking if the tooth they are looking to purchase or have in their collection been restored, extended or is fake. Most all the teeth in question come from Morocco and are Spinosaurid (sold as Spinosaurus) and Carchardontosurid (sold as Carcharodontosaurus). Sellers sometimes are aware of what they have and will state the resto and repairs, others may just be clueless, and others may just be deceptive. Bottom line you always need to be very cautious with of any of these purchases. How to avoid disaster 1) Buy high quality teeth, yes it will cost you more, but it may be the only way to insure you are getting what you are looking for. 2) Become educated on what good and bad teeth look like and hopefully this topic may help. 3) Unless you are a real expert post your interest here on the forum before you purchase. 4) When buying anything online make sure it can be returned for a full cash refund 5) No guarantee but purchase from reputable dealers. Avoid auction sites they typically have the most problem teeth. Characteristics of Theropod roots: : Roots are not solid they are typically hollow and thin walled : Although they are all slightly different depending on jaw position they may or may not have a lingual or labial depression which may begin in the crown. Some may have a cavity, resorption pit, where the replacement tooth sits : Roots should have some taper from the lingual to labial side, Spinosaurid roots are not round : Roots may have a sheen depending on preservation. Here are a few in my Collection to see what high quality rooted teeth should look like Juvenile small Spinosaurid tooth What are red flags: : Matrix, matrix and matrix. Moroccan's use it to hide defects, composites or repairs. Avoid avoid ones that cover large areas.. : Colors, Colors and lots of different colors.... : Different surface textures. Look at the examples there is a consistency in color and texture. The surface is homogeneous.. : Teeth with long roots should be priced accordingly. If you are looking at something big and all real it will be expensive. : The transition between Crown and Root should be smooth, no bumps, gaps and areas of fill My Recommendation: Save your money and only purchase teeth that have clean roots. Don't waste your time figuring out if it's been repaired, composited etc. or hoping its good. Photos may not be adequate to see everything. UV lights typically do not work on Moroccan matrix resto. Best to be able to see what you are buying and not rely on guess work. These clean rooted teeth are available you just have to be patient and be willing to pay more. Now the ugly Everything I've mentioned is seen below Extended Fake root Orginal root Extended Seller said this was composite Fake Root, Looks like a Cylinder Fake root, Wrong shape Extended Banana Spino Tooth . Who can say whats going on here Fake Root Fake root, Crown that has repaired/restored??? Composite using matrix fill

I finally made a start with a project I was planning for a while now: drawing the Kem Kem dinosaur fauna! First I will draw each dinosaur individually and then I will combine them all in one big landscape. As you can probably tell, I am not aiming for 100% scientific accurary. I do however try to take into account what I know about these animals and what is known about their skeletons. This is the first one and probably the most iconic of them all: Spinosaurus. I will give regular updates here about this fun project, so stay tuned!

Hi guys I have these 3 similiar mosasaur teeth that I was wondering if it was possible to identify, are they prognathodon thanks! 1. 2. 3.

Please tell me what brachiopods are these? They come from Morocco, Devonian-Carboniferous. Thank you!

Never surprised at what may pop up in the Kem Kem, another twist, we really do know so little. All those collectors that think they have big teeth from Deltadromeus may have to change their thinking. Nothing here is set in stone, we still need a skull to fully describe this dinosaur. Christophe Hendrickx posted this: "According to this abstract, Deltadromeus would no longer be a noasaurid ceratosaur or a neovenaptorid allosauroid but a basal ornithomimosaur! This taxon moves so much along the theropod tree. It really needs a detailed description!" This is an abstract from a talk by Max Kellermann best image I can find
