Fully rooted pterosaur tooth?!!!

[DatFossilBoy]

Hi all.

I saw this online and I was amazed.

The fossil is sold as a pterosaur tooth from Kem Kem.

 

Size:  49 x 8 mm 

This species of pterosaurs could reach a wingspan of up to 6 meters ! »

 

Could it really be a fully rooted pterosaur tooth? For me it’s really big for a pterosaur.

What do you think? Never saw a fully rooted one. Rare? Do you think it could be a fake?

Regards.

A fully rooted pterosaur tooth can reach this length. The tip to me looks a bit weird but that could just be me. @Tidgy's Dad and @Troodon will for sure be able to help.

I think it's real, and it looks nice, but I agree with @indominus rex that the tip looks a bit weird. It's not a small tooth,  but I isn't that big either.

Maybe it’s just me but it looks suspiciously like a hybodontid fin spike.

I think you're right. 

Looks like a hybodont shark dorsal fin spine with an odd end fixed on. 

I don't think any of it's pterosaur at all.

Looks more like a Plesiosaur tooth the root is rounded but I don't think they are in the Kem Kem so no idea.  

Here is Pterosaur rooted tooth

I think one of these fins spines with the end missing so they glued something else's tip on the top.

The root is oval not flat so I'm not seeing a spine more like this one that belongs to Andy.  But his is not Kem Kem.  We can all agree it's not pterosaur?

I agree that this fossil in the original post looks quite odd. Doesn't look very much like a pterosaur tooth to me either. I don't think it looks like the typical hybodont spines either as it seems very round. Though they have spines in several places. Maybe a spine from a different area of the shark? I'm not that familiar with sharks so I dunno.

But yeah, I don't think it's pterosaur.

Me neither but maybe pectoral fin?

I totally agree.

Probably not Pterosaur. Not too sure if it’s a shark spine though,they look quite different.I can see a difference between the tip and the tooth. Couldn’t it still be a tooth?

Thanks for the help.

Regards.

Ps: notice that the bottom of the fossil is hollow.
