Fossil of Spinosaurus arm, real or not

[Cris Tang]

Hi, Thank you so much for helping me last time.

May I know the fossil is real or not, please?

Thank you.

I have not seen anything published on the arm bones of Spinosaurus but if you compare it to the National Geographic reconstruction by Nizar Ibrahim, Paul C. Sereno et al. it does not compare well.

As @Troodon said it does not compare well to a Spinosaur, so I’m thinking it could be a Carcharodontosaurus, but not a lot is published on this topic so it’s just a guess.

Just curious why do you think this may be Carch?

I’m guessing that it’s a Carcharodontosaurus, due to its size showing that it came from a large animal. And it’s length and width, since Carcharodontosaurus had long and skinny arm bones, comparable to this bone.

Crocodile humerus?? Just a guess.

For Kem Kem material since very little is published the best approach its to try compare it to Dino's papers from South America where much more is available.    Check out the Carch Tyrannotitan from Argentina and you would see that this bone would not fit.    I dont believe this bone is dinosaurian and feel like Tim its Croc.

I'm in the croc camp: possible croc humerus....
