Can anyone tell me what this is? All I know is it’s from Kem Kem. My best guess is some type of crocodile. What else even has all those nerve channels besides crocs and the spinosaur family? I think the shape(top&bottom view) looks similar to pancake croc jaws, and I’m pretty sure there were a number of others with that type of jaw, but I don’t know when and where they were, sooooo.......does anyone have any thoughts about it?

No volcanic winter in East Africa from ancient Toba eruption.

No volcanic winter in East Africa from ancient Toba eruption. The supereruption 74,000 years ago did not trigger major environmental disruption that caused human populations in East Africa to decline, say geoscientists.

Ancient DNA reveals ‘profoundly different’ human landscape in prehistoric Africa

as a connoisseur of Pterosaurs, I wanted to ask the Community here to show me it's pterosaur fossils from the Kem Kem Formation. After seeing a rare Tapejarid Premaxilla recently get sold on a Fossil Dealing site (labeled incorrectly as Alanqa), I wondered what treasures could be present in Private Collections in this Community. Teeth are just as welcome as Bones are.

Hi everyone, Can you help me identify what animal this may be? It was found in Botswana. It is a semi-arid climate. Any idea if it's carnivorous or not? Any clues are helpful! Thanks.

Pterosaurs of the Kem Kem Beds, more than just Coloborhynchus and Alanqa.
Sassy PaleoNerd posted a topic in General Fossil Discussion
Pterosaur Fossils are a rarity, and few ever are on the public market, but the Pterosaurs from the Kem Kem Beds are seen most commonly on the market, this is rather not due to an unusally high Pterosaur abundance, but rather because almost every Fossil is being collected at this locality. Currently, there are 4 named species from the Kem Kem Beds, but the actual number is far higher. The Named Taxa are Alanqa saharica, Xericeps curvirostris, Sirrocopteryx morrocanus and Coloborhynchus fluviferox. Some unnamed ones im allowed to talk about are the Kem Kem Tapejarid, a small Chaoyang- 6 replies

Hi, All. The best I can do with this is simply put up the pictures and let wiser minds than mine (ie: everybody else!) take a look. I don't know what this is; it has tooth-like qualities, but I just can't get a handle on it. It would have come from the Agadez area of Niger, for what that's worth. Thanks for looking!

Hello so could someone please explain the situation with sigilmassasaurus and spinosaurus was it the same dinosaur? was sigilmassasaurus bigger? Thanks
-
So after following nizaar ibrahim's study in 2014 I learned that spinosaurus walked on four legs and it spend a lot of time in water being a good swimmer. But recently I saw that some new studies have been published and then some others and I have lost track so if someone could please inform me about the latest discoveries and tell me if spinosaurus was a good swimmer and if he walked on four it would be much appreciated.

Hi, All. I came across this yesterday, but couldn't make heads nor tails of it.... I want to think it's not a bone - one side is very smooth, while the other has a tone of small stones attached to it - but the view of the inside has me wondering.... Thanks for looking at it, and telling me what I'm looking at. I seem to have a really long learning curve! Rob @LordTrilobite @Bone guy @Haravex @Troodon

Hi, All. Okay - I'm trying to learn here, so please bear with me! I've been told that many of the teeth I've acquired here in Niger have been croc teeth, and that one of the ways to tell a croc tooth is by a circular base (basil?), while spinosauridae teeth are more oval.... That said, I offer the following two teeth for your informed evaluation! The bigger one is relatively narrow (the side shot with the enamel curving over the top gives you an idea), with the smaller one has a distinct "ridge" on each front/back (I know those aren't the technical terms - sorry!). As always, I

Hi, Folks. Thank you so much for the feedback on my first posting of teeth! Apparently there were more than a few crocodiles in the Agadez area of Niger, back when it wasn't desert! I'll post the next set, and follow that up with a posting of another very large fossil from the same area. I truly appreciate the education I'm getting on here!

Hi, All. Here's another "large" fossil I've acquired. Same origin as the others - Agadez area of the Sahara desert in Niger. Based on the feedback I got on an earlier submission, I'm wondering if this could be from a sauropod and, if so, what part of the skeleton? As you can see, there's a lot of mud on it that I haven't tried to remove yet, as I am a complete neophyte and don't know the proper way to do so. I welcome any and all guidance on that too. Thanks so much for all your replies! Rob @Haravex @LordTrilobite @jpc @Troodon

Hi, All. I finally managed to photograph all my teeth with a scale, and am hoping for someone with a lot more knowledge than me (ie: just about anyone on this site!) to tell me what I've got. I've got them divided into 6 different sets of teeth, and tried to photograph them with a bit of logic (teeth in a row, teeth flipped over to show other side in a row, bottom of teeth displayed one at a time in order, etc.). I'm trying to learn the difference between types of teeth (crocodile vs. spinosaurus vs. m-something, etc.), so if there are any common clues, I'd really appreciate the

Fossils, including Trilobites, in the Cultural Life Of Prehistoric Africa
