Good day to all members! I am looking for a nice Spinosaurus aegyptiacus tooth, no smaller than 8cm and as well preserved as possible. I know well that the market is full of composite or fake finds, especially when it comes to larger teeth. And here I am again asking you for advice on these 2 teeth for sale. They both seem genuine to me, but I wanted to ask you for help since I still have a lot to learn. Also regarding the conditions, keeping in mind that the most important thing is to buy the fossil I simply like the most, I would like to ask your opinion on which of the two teeth you consider the best preserved considering that teeth in this size are not cheap. Both are described as natural without restorations. Thanks in advance to anyone who can give me their opinion

I bought this tooth on impulse a few days ago. To me it looks like a fully rooted Plesiosaur tooth. It has all the characteristics of being from the Kem Kem Beds aswell. I've not seen any other rooted teeth to compare it to. So, did I score, or did I buy a crocodile tooth?

Hi, I bought this for [price redacted]. It was labeled as a theropod femur but through research and showing it to others I think it might be crocodile. I'm not sure so if anyone of you has any thoughts about this piece feel free to tell me. Its 97 myo btw.

Crocodylians are some of the most under-appreciated parts of Mesozoic and Cenozoic faunas. While it's a common to assume that they are "living fossils" and barely changed since the Triassic, this is actually false - crocodylians were, and still are, extremely diverse. Systematics of these organisms can be confusing, so in this thread when I say "crocodiles" I mean Crocodylomorphs - a larger clade that includes extant crocodiles and their extinct relatives starting in Triassic. Let's start, of course, with Upper Cretaceous Kem Kem beds in Morocco. Those deposits were home to famous dinosaurs, such as Spinosaurus and Carcharodontosaurus, that ofen overshadow the incredible diversity of local crocodylomorphs. Clade: Crocodylomorpha Clade: Crocodyliformes Clade: Metasuchia Clade: Neosuchia Family: Pholidosauridae Species: Elosuchus cherifiensis Elosuchus was the largest and one of the most common Kem Kem crocodylians. Its taxonomy is debated, but it was most likely a Pholidosaurid, a member of the family of large, aquatic crocodylomorphs that were close to the base of crocodylomorph phylogeny. Another famous member of this family is Nigerien Sarcosuchus imperator, one of the largest crocodylomorphs. Unfortunately I don't have any pictures of its teeth at hand, so feel free to add any of your own! I do have this partial premaxilla. Premaxillae of many pholidosaurids can be easily identified because of their bulbous shape. Elosuchus teeth were large and robust, sometimes with enamel ridges. Family: Stomatosuchidae Species: Laganosuchus maghrebiensis In my experience looking at various commercially available Kem Kem fossils, this species is one of the rarest. Laganosuchus was a stomatosuchid - a family of crocodylomorphs with strongly compressed skulls, earning them the name of "pancake" crocodiles. I have a small dentary section, close to the symphysis - connection between left and right halves. I believe it is a stomatosuchid because of how compressed this section is, considerable distance between tooth sockets (alveoli) and short symphysis, as seen in Elosuchus and many other crocodiles. Here is a similar L. maghrebiensis dentary fragment with a tooth; and a L. thaumastos tooth (Sereno & Larsson, 2009). Here is a lower jaw of L. thaumastos from Niger that displays the "pancake" shape (also Sereno & Larsson, 2009). Clade: Metasuchia Clade: Notosuchia Notosuchians were primarily terrestrial crocodylomorphs, known since the Jurassic but reaching their peak diversity in the Cretaceous. There are a few species known from Kem Kem beds: Hamadasuchus rebouli, Antaeusuchus taouzensis, Araripesuchus rattoides and Lavocatchampsa sigogneaurusselae (unfortunately don't have any specimens from this one). A unique trait of notosuchians is strong heterodonty - differentiation of teeth. Many species had well-defined incisiform, caniniform or molariform teeth, functionally equivalent to incisors, canines and molars in mammals. Family: Peirosauridae Species: Hamadasuchus reboulli Hamadasuchus was one of the two peirosaurids in Kem Kem, the other one being Antaeusuchus. Antaeusuchus was larger than Hamadasuchus, had less ornamented dentary surface and significantly more robust teeth. Here is a dentary from Hamadasuchus, displaying the diagnostic triangular and labio-lingually compressed posterior tooth. You can read more about the differences between these two taxa in Nicholl et al., 2021. Here are a few Hamadasuchus teeth from various tooth positions. Many of these have fine serrations, another characteristic trait of notosuchian teeth. All scalebars are 1 cm. Family: Uruguaysuchidae Species: Araripesuchus rattoides Araripesuchus was a small terrestrial notosuchian with gracile anatomy. It also had clear heterodonty but its teeth were considerably smaller than those of Hamadasuchus. Additionally, the dentary was less apico-basally expanded. I have a dentary and a partial maxilla from different individuals. You can clearly see how heterodont this species was from the size of the alveoli. Teeth of A. wegeneri from Niger: Notosuchia indet.? This is a dentary section that I've been struggling to identify. Its extremely elongated, but certainly not Laganosuchus because it looks like left and right halves were fused along the entire length. Also, alveoli are not spaced enough for Laganosuchus or Elosuchus. The one preserved tooth is strongly compressed and has visible denticles, which points to a notosuchian. However, it could also be Aegisuchus - an aegyptosuchid crocodylomorph, jaws of which are unknown.

I bought this from a store but they or me didnt know what tooth this is so they sold it to me as a herbivore tooth. Any idea what this is? Its 95 - 97 myo. Kem Kem beds, Morocco.

Hi all. Are these pterosaur teeth as I suspect, or could they be something else? Just double checking as I am planning to use them in a project. They are from the Kem Kem beds in Morocco. Thanks!

Hi all! Here are some teeth from the Kem Kem beds in Morocco. Are they all crocodilian, or could they be something else? Number 3 and 6 are from Talsint (Dekkar formation) and are still in matrix, so this is the only angle I could photograph them. I do not really have much doubt about most teeth, except number six (but I would have no idea what else it could be), but would like to double check. Number 6 is approximately 3 cm long. Thanks for your insight!

im guessing the tip isn’t from the same tooth but what about the root? it’s a very nice looking tooth though. thanks in advance

Kem kem bones, supposedly Spinosaur Hello all, i recently got two bones that come from Morrocco, kem kem formation, suposedly belonging to a Spinosaur. They seem quite peculiar and could actually come from anything. Attached are some photo’s, does anyone have an idea what it could be?

Hi, Was wondering what this could be. It is 19cm and I suspect it could possibly be from a theropod, but it might instead be something else. Thanks!

Hello! This is my first post so be gentle I have a vertebrae from Morocco here that i cant seem to figure out. The owner of the collection I'm examining recalls purchasing it from Morocco, but doesn't recall if it comes from the Kem Kem beds or from the High Atlas Mountains. After some dusting and light acetone cleaning was able to determine that it is in fact a vertebra, but I'm not sure of the species, as the piece is slightly deformed and lacks processes. My best guess so far is a sauropod caudal vertebra, possibly Rebbachisaurus, but I'm having difficulty in finding any reputable sources that would confirm this. I could also understand if it came from a large theropod, but has lost its shape due to deformation. Sadly, most of my expertise is with Hell Creek fossils, so I'd really appreciate any help that can be offered Lastly, if the piece is of any significance (undescribed or poorly described species) it will most likely be donated to the local museum! So that would be cool. Thanks again!

Hi all, A friend in North Carolina has this (among many other) box of bones from Morocco that need some sort of ID or general push in the right direction. I haven't been staring at bones long enough to make sense of these, but the tray they're sitting in is 15 inches long. My own personal uneducated guess is that I see some metacarpals and other small hand bones, a metatarsal or two, etc. , but I welcome outside opinion. I have my eye on the one top right, first in the group of 3 so I'm especially curious about that one. Mahalo!

Hello, Can you help me with ID of this tooth? I am not sure whether it could be Carcharodontosaurid or something else? I bought it at a fossil show, Its supposed to be from Morocco, Kem kem group, Taouz. Scale is in cm. Measurements: CH - 2,8cm, CBL - 1,6cm, AL - 3cm and CBW - 0,8cm. Thanks in advance.

I recently saw this tooth for sale identified as a Deltadromeus, but it looks suspiciously similar to teeth sold as "indeterminate Abelisaurid", mine included, so I thought it would be worth checking. The seller has stated the tooth is "17mm x 10mm at the widest points". No other measurements were given. Thanks in advance for any guidance Othniel

I recently saw this sawfish rostral barb up for sale as that of an Onchosaurus, but it looks very similar to those sold as Onchopristis: so which is it? Thanks in advance for any guidance Othniel

Hey, I recently went on a website that sold Spinosaurus tooth and saw that it had the description of from Oued Zem Morocco, I then asked them if it is the same as kem kem and why aren’t there Kem Kem the person then respond with because kem kem fossil are more fragile for transport which I did not believed so I asked them again, this time there was a delay maybe they went to ask someone else? Responding with it’s in Kem Kem just north, I feel like this is accurate since I heard it somewhere but not certain, may someone give me some insight on this, Thanks.

A digital illustrations of two sauropods. One of them represents a titanosaurian, the other a titanosauriform. This is part of a series of illustrations related to my Kem Kem poster.

Hi, This is only photo until the tooth I arrived--I bought it when I saw it because of the low price and the fact it is quite unusual. And this was the only pic on the site. A tooth, sold as crocodile from Kem Kem. 9mm in height. It looks a bit like Hamadasuchus, but with that ridge down the center. A different positional Hamadasuchus tooth? Or a juvenile? cheers I will post more pics when I can.

Hello everyone ! I have these two fossil vertebrae from the Kem Kem formation from Morocco (no exact location) and I can't identify them. Can someone help me please? They are very different from each other. The red vertebra n.1 has an oval shape and has mirrored holes on both sides, while above it has a larger some. I initially thought it was Hybodus or Onchopristis, but I'm not sure, it could be many other shark species. The white vertebra n.2 does not have any type of hole on the edge and is almost perfectly round, I believe it is a completely different species from the first. Thank you.

Hello fellow forum members, some time ago I acquired what I thought of as a theropod ilium from the kem kem . it just crossed my mind that it could be another kind of archosaur alltogether, maybe a crocodylomorph? What do you think? At the moment i can not take more pictures of it easily, but maybe one is enough? Thanks and regards, J
