Pterosaur tooth?

[Vieira]

Hello,

 

I need help to identify this tooth, found by me in a Jurassic formation in Portugal. My first thought it's Pterosaur. I wait for your opinions.

 

The tooth have 1cm.

 

 

Thanks,

 

Filipe

Yes Troodon.

 

What you think? Pterosaur?

[Troodon]

I don't know, there are no pterosaurs that I'm aware of described from that fauna however Rhamphorhynchid type teeth have been found.  The only paper I have  shows an indeterminate photo (b) of one. (Scale bar is 10mm)  Is the base of your tooth round or oval.

Ok Troodon.

 

Thanks

I think it's round but I will check tonight.

If it's oval it looks a lot like the Pterosaur teeth you see from the Kem Kem.  Are there marine deposits where  you collect, I'm not aware of any.

Yes, are marine deposits there. In most formations there the deposits are terrestrial and marine...mixed. You can find a theropod tooth and a fish tooth or scale in the same place.

Marine not being fresh water but ocean.  When I relooked at your tooth it appears to have a cutting edge is that correct?

Sorry Troodon, you right.

I'm not certain but I think so. Tonight I will see better those details....

[Troodon]

Could be croc if the cutting edge is present and the base round

Hello!
Yes, it's a Rhamphorhynchus Sp. not extremely rare in Lourinhã formation,
What is TRULY rare is the fact that is so complete (mostly are incomplete specimens ) and the extensively presence of  the thin enamel that vanishs from other finds.

Grande achado!
