terapoza Posted December 21, 2017 Share Posted December 21, 2017 I would say Cyclolites if it would be Cretaceous. 1 Link to comment Share on other sites More sharing options...
abyssunder Posted December 21, 2017 Share Posted December 21, 2017 The sediments of the Dhruma formation are Middle Jurassic - Bathonian in age. Are you sure you're not hunting in the Upper Cretaceous? 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

terapoza Posted December 21, 2017 Share Posted December 21, 2017 I found article about Dhruma formation. Jurassic rocks are followed by Cretaceous marls and limestones. Link to comment Share on other sites More sharing options...
abyssunder Posted December 21, 2017 Share Posted December 21, 2017 The specimen in question looks close to Cunnolites. Here are described and illustrated eight species of the genus from the Maastrichtian of Central Saudi Arabia: M.A.Ghalib El-Asa'ad. 1990. Maastrichtian species of the coral genus Cunnolites from Saudi Arabia. Journal of African Earth Sciences, Vol. 10, No. 4, pp. 633-642 Hope this helps. 2 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

HansTheLoser Posted December 22, 2017 Share Posted December 22, 2017 Cyclolites is a solitary coral. Cunnolites is a junior synonym. The depicted fossil could be Aspidastraea. Same family, but colonial. Known range: Upper Campanian to Maastrichtian. 3 Link to comment Share on other sites More sharing options...

Pachy Posted December 24, 2017 Share Posted December 24, 2017 Cyclolites and Aspidastraea are from the same family, yes. But of the Cyclolitidae family. 1 Link to comment Share on other sites More sharing options...
HansTheLoser Posted December 31, 2017 Share Posted December 31, 2017 corallosphere = mix of good and bad data, not very trustworthy since you never know which quality has a specified item. Link to comment Share on other sites More sharing options...

But if you know how to choose the good there is good information there. For example, in this case there are images of the type specimen of Aspidastraea. It's just a matter of knowing how to choose. Take advantage of the good and undo the bad. As in life itself. You have easy access to this kind of thing, I have to get them out of here and there with a lot of work and knowing how to choose.

abyssunder Posted December 31, 2017 Share Posted December 31, 2017 You can contact the editor if you would like to contribute to the diagnosis of this taxon, eventually change the family name Cunnolitidae to Cyclolitidae.
