Is this Spinosaurus tooth real ? (need advice for purchase)

[Niranjan]

Suggest some good sellers from online auction site (preferrably from Europe)

Seller did not provide a scale for measurement

Need suggestion from other websites too, if possible, (no retailers)

[Troodon]

Do you have photos of the other side?  Looks like a Spinosaurid cannot say for sure its Spinosaurus or Sigilmassasaurus

[Niranjan]

These are all that the seller uploaded

If you are looking for a Spinosaurus tooth I would suggest continue searching, as this is a very small and not very well preserved tooth, and perhaps belongs to another spinosaurid kind. A typicall spinosaurus tooth is very common

It looks to be a Kem Kem spinosaurid tooth. I would ask for better pictures of the root, though. The pictures don't show it very clearly and that area is a usual target for extension/fabrication.

This is 100 percent real, the pitting at the bottom of the root suggests its a shed tooth. No way to tell which species it belongs to best labelled as spinosaurini
