Dear Guys,

 

I noticed many different forms of Lungfish dental plates in my collection, especially from Late Famennian dolomites from the Zagare quarry. 

Please help to identify genera of these teeth, if you cannot do it then please help to find a specialist on this type and age of remains if you could. :) 

 

Best Regards

Domas

I see a few toothplates that are consistent with something vaguely Chirodipterus-like, as well as several toothplates that I'd be comfortable calling cf. Andreyevichthys. Some are kind of uncertain but would probably represent something vaguely Rhinodipterus-like. This is a neat little collection.

Dear jdp, thank you! :) 

Which toothplates to which of three types do you determine? 

As I would say Chirodipterus like are 1st, 3rd, 5th and 6th pictures, Rhinodipterus like- maybe 2nd? picture, Andreyevichthys like would be 4th, 7th and 12th? :)

Please explain me which finds belong to that taxa, it is important to my scientific articles. :D 

 

Regards

And also one question- is Chirodipterus rare genus in Europe? :)

That is why You should number the pieces when You post several specimens.

It gives the replier a reference to the comment.

Ok, now I am going to number and write opinions about each of them. :) 

 

1. Possible chirodipterid, Late Famennian.

8. I do not know what it is but even similar to Protopterid or Ceratodontid (??), Late Famennian.

9. Maybe Chirodipterid or Andreyevichys but it is only 2 mm length... Late Famennian.

Maybe Rhinodipterus like lower plate? Late Famennian.

15. I would say Dipterus or Andreyevichthys. Late Devonian, probably Frasnian but can be also Early Famennian...

And the new one from Late Famennian- Tournaisian. Maybe you have seen it earlier, 

I think it could be Sagenodontidae indet. but not sure... :)
