gigantoraptor Posted January 5, 2019 Share Posted January 5, 2019 Hello all I found these two fossils in 2014 during a trip in Vierves-sur-Viroin. These are Devonian in age and were found together with trilobites, brachiopods... First one is some piece of coral I guess, no idea what kind. About 3 mm in diameter. Second is a mystery. I have no idea if these are fish vertebrates (which would be rare since it is Devonian) or crinoid parts (never seen any that look like these from the Devonian of Belgium, but I might be wrong) or something entirely else? I see at least 6 of them in the matrix. It's 3D and I don't dare to prep it any further untill I know if it's rare or common. Thanks already.

Tidgy's Dad Posted January 5, 2019 Share Posted January 5, 2019 Yes, a button coral like Microcyclus, I should think. And the others look like crinoid bits to me. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I am not sure yet if the first one is indeed Microcyclus but there are indeed some similarities. While searching for those I found these online. They look nearly identical to the second one, altough these are younger (carboniferous) and bigger. They are labbeled as trace fossils. Do you guys know anyone I can contact to get certain? Are there any palaeontologist specialised in these? Link to comment Share on other sites More sharing options...

I would be more inclined to trust either of these guys than the person who labeled these trace fossils. To be fair I can't see them well enough to tell if they are the same as what you have though. 1 Link to comment Share on other sites More sharing options...
fifbrindacier Posted January 6, 2019 Share Posted January 6, 2019 I agree that on your third photo there is a crinoid stem.

abyssunder Posted January 6, 2019 Share Posted January 6, 2019 Microcyclus might be a good ID, but can we have a more focused image of it? 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.

Are there any palaeontologist specialised in these? I agree both these and your second specimens may not be crinoids but there's not enough detail to characterise them for sure. So it's hard to know what sort of specialist you'd need - anyone know an ichnologist? Tarquin Link to comment Share on other sites More sharing options...
abyssunder Posted January 6, 2019 Share Posted January 6, 2019 They could be even lower sides of Microcyclus, but the image is far too blurry to understand the features of what is presented there.

Manticocerasman Posted January 8, 2019 Share Posted January 8, 2019 those rocks are early givetian ( Hannonet formation ) this might help to get you on track for determinations , there are a lot of papers and publications on the Belgian devonian. ( although lots of old publications ) growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...
