Strange China fossil/battered tooth

[FF7_Yuffie]

So, the fellow who I get some of my China pterosaur teeth from has offered me this fossil among a few other worn/battered/partial teeth. 

 

He can't place it--says it is possibly a tooth of some kind.

 

It is Jurassic age, from GuangYian City, SiChuan Province. Unfortunately, he doesn;'t know which of the two formations from there it is from. There are two--Shaximiao which is a terrestrial formation and Zhenzhuchong which is mainly marine but has had prosauropod (Lufengosaurus found there). 

 

Unfortunately it is in quite a poor condition--but I am hoping someone may recognise it at least similar to others, so I can get an idea if it is a hadrosaur, prosauropod etc. I am wondering if it could be a worn and battered ornithopod tooth--there are a few from Shaximiao.

Might not be a tooth. Crab claw is a possibility.

I would also question if its a tooth but cannot add any more to its ID.. It does not look like Massospondylid type tooth.

Thanks. Seller himself wasnt sure if it was tooth or not. Crab claw would fit--one of the possible formations was marine, and the other teeth he offered today were from the marine deposits.

 

It is one I will pass on.

 

Thanks
