Spinosaurus or crocodile tooth?

[Kurvinosaurus]

Hello! I bought this tooth from a gift shop. It was labeled a spinosaurus tooth. I’m just wondering if it most likely is a spinosaurus tooth, or a crocodile or something else? Thank you!

Looks like the tip of a Spinosaurus tooth.

Im leaning more towards croq. The enamel is different, and notice the clear vertical lines on the last picture. Shape is also what I would expect to be croq, lets see what others might think of it :-)

Thanks for all your replies. I was watching a video of a spinosaurus presentation by a paleontologist, and he said many of the spinosaurus teeth being sold are actually crocodile because it’s extremely difficult to tell them apart because they are so similar. I guess it could go either way.
