markhero Posted January 17, 2017 Share Posted January 17, 2017 Please help me with the below.. I found this pectenoid fossil and many more in the rumbles of an old mine in Attika area af Greece. Usually the terestrial fossils near the beach are of Pliocene or Pleistocene age. But this fossil comes from the digged earth of a mine and looks totally different than the Pliocene shells. It has Black color and the shape is also different.. It reminds me of Neithea species?? But Neithea were Jurassic era fossils... Could it be??? Size 3cm X 3cm.. Thank you very much in advance...!

There are plenty of Cretaceous Neithea, and I think the range of the genus was into the Paleocene. 1 "I am glad I shall never be young without wild country to be young in.

The beds above the mine are Pliocene age, but this does not look similar to any Pliocene shells that I know.. Do you have any idea?? Link to comment Share on other sites More sharing options...

If this is really a Neithea, which it certainly appears to be, then it cannot be recent, since they went extinct in the early Paleocene. Greetings from the Lake of Constance.

abyssunder Posted January 21, 2017 Share Posted January 21, 2017 " The subfamily Neitheinae forms a well-delimited group of Cretaceous Pectinidae, occurring both in Lower and Upper-Cretaceous. After the Maastrichtian no more Neithea-species are found. They die out before the Danian. " - as stated in Annie V. DHONDT.SYSTEMATIC REVISION OF THE SUBFAMILY NEITHEINAE (PECTINIDAE, BIVALVIA, MOLLUSCA) OF THE EUROPEAN CRETACEOUS. INSTITUT ROYAL DES SCIENCES NATURELLES DE BELGIQUE MÉMOIRE N° 176 — 1973 Although there is a very good revision of the Neitheniae subfamily of Europe, there's no mentioning of Greece specimens, at least till the end of 1973. I don't know if it helps or not, but I'll put up the plates from the document mentioned, also, I would not rule out the possibility of Neithea. 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.

markhero Posted January 23, 2017 Author Share Posted January 23, 2017 abyssunder thank you very much for the informative reply. I also know that Neithea species were not discovered in this area ,that is why it is so important for me to be sure, it could be a great discovery.. But in this particular area, the sediments are : Pliocene on top of Cenomanian... These 2 layers are located on top of each other and they are both limestone. The Cenomanian cediment in this area usually consists only of rudists and orbitolina that means only deep ocean finds, nothing like shallow water Neitheas.. In the same bed with the suspected Neithea, I found gastropods and Cardium sp, indicating towards the Pliocene era... I am trying to figure if the specific shell is a new species? or maybe a common scallop with deformed shape?!? Link to comment Share on other sites More sharing options...
