Caverat Posted March 9, 2021 Share Posted March 9, 2021 We recently had limestone tile flooring installed and selected a sample labeled "Fossil Tile". The wrapped packages indicated country of origin as Turkey. I have studied numerous features in the tile and believe they include belemnites or cephalopods, but there are irregular masses with bumpy linings that I'm unsure about. I'm interested in learning what region the stone may have come from, the geologic age and especially, the identification or possible identity of the "fossils". I've inspected broken tile edges for surface features that might tell more than the polished cross-sections, but found nothing thus far. Link to comment Share on other sites More sharing options...
jpc Posted March 9, 2021 Share Posted March 9, 2021 cool. The 6th photo down is a brachiopod in cross section. Link to comment Share on other sites More sharing options...

No one else has offered any thoughts on the irregular masses that are so common in the tile... And no thoughts on the Turkey quarries or possible limestone age.

fifbrindacier Posted March 13, 2021 Share Posted March 13, 2021 On the net i found a quarry of marble fossils, Akdag Creamsa in the Sivas basin in eastern Anatolia with three layers : Oligo-Miocene, Eocene and Maestritchian.

Thanks! Your web searching is definitely superior to mine. All I was finding was ads to sell tile with no background information. With your keywords, I should be able to research some more. Thanks again! Link to comment Share on other sites More sharing options...
abyssunder Posted March 13, 2021 Share Posted March 13, 2021 First three pictures remind me of rudist colony in transverse section if the geological time is Cretacious.

If the source is Turkey, the quarries appear to be in the Eocene to early Miocene. I looked at rudist colonies at your suggestion and I will keep that possibility in mind. Thanks!

pachy-pleuro-whatnot-odon Posted March 13, 2021 Share Posted March 13, 2021 From what I understand from @fifbrindacier's search results, it could also concern Maastrichtian sediments, which would make the fossils Cretaceous in age. This would seem more logical of an assumption if the tiles indeed contain belemnites, as these went extinct after the Cretaceous. And while I realise this is circular reasoning, the presence of rudists, supported by the presence of belemnites, might actually not just give you an identification of the embedded fossils, but also of their (Late Cretaceous) age. This should help you narrow down where the tiles could have come from. I'd advocate this approach, rather than doing it the other way around by first determining where they may have come from to then see what fossils the outlines may match...

I will continue to pursue this and another proposal I received on the Fossil Forum Facebook site and that was microbialites or microbial crusts. There is a probable cross-section of a brachiopod (image #6) and it has the clotty or bumpy appearance on the inside... Also, I see some features have a very smooth inner region and other have the bumpy surface inside... Link to comment Share on other sites More sharing options...
