Howdy all, I'm interested in this Afrovenator abakensis tooth and am curious if it's legit. It was found in the Middle Jurassic Irhazer Shale of Agadez, Niger and is 1.3" long.

I recently purchased Niger fossils, and as expected, provenance was poor. I know it's ill-advised to buy fossils without good provenance, but I decided to take a gamble here. There was a sliver of hope in getting provenance as the seller could contact their source in Niger, but alas, outside Agadez is the best they got. The first fossil was sold as possible Kryptops, and 2nd just Theropod. I also got fish fossils from the same group. Elrhaz, Irhazer II, and Tiouraren appear to be the 3 formations in that region, and most fossils from Niger you often see for sale are supposedly from one of the 3. Not 100% sure if there are other formations to consider in the Agadez area. I know the white-ish fossils are typically the fossils attributed to the Tiouraren fm., but I don't think the darker or even solid black colored fossils are necessarily excluded. If Theropoda indet. is the best ID, that's fine. They're also not complete which is already bad in of itself. 9/10 times fossils from Niger have poor provenance, or none at all, so it's just on par for course. Tooth A - I think the denticle shape and density is wrong, and it might to be too big to be Kryptops. Distal Serration: 11/5mm Mesial Serration: 11/5mm Tooth B - Serrations appear to be worn under a scope. Distal Serration: 10/5mm Towards Tip - 11/5mm Towards Base Mesial Serration: 10-11/5mm Fish - Not really expecting ID from fish chunks. But maybe something about them might give away age . . . probably not. The group of specimens here are stuff I didn't buy, but belong to the same group. I saved pictures of all of them to possibly narrow down a formation or locale, though I'm assuming the diggers in Niger just pile up all their findings into one pot regardless of where they dug them up similar to the stuff from the Atlas Mountains in Morocco. I think the sauropods suggest Jurassic, but again, everything could have been piled up in one lot.
