RomanK Posted June 22, 2009 Share Posted June 22, 2009 Last hunting I have found some strange specimens - huge amount prints looked like seeds. I can't ID ones, and even not sure whether they are plant fossils or small shells, cause I never found something like this. Has somebody any idea?

moonmoth Posted June 22, 2009 Share Posted June 22, 2009 hi romank, my guess would be non marine bivalves, i could easily be wrong tho Link to comment Share on other sites More sharing options...
Auspex Posted June 22, 2009 Share Posted June 22, 2009 There's something of a concentric structure on some of them (last picture especially) that makes me think they might be clams?

RomanK Posted June 22, 2009 Author Share Posted June 22, 2009 a wee bit like these ? I don't think so, it's a bit different thing. On your pic you can see clams clearly. Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...
RomanK Posted June 22, 2009 Author Share Posted June 22, 2009 There's something of a concentric structure on some of them (last picture especially) that makes me think they might be clams? May be yes, not sure. This is tipical multilayered dead rock like clay with thouthands very thin layers. It's very fragile rock which easily brakes in your fingers.

docdutronc Posted June 22, 2009 Share Posted June 22, 2009 Hi Roman no problem ,I can tell you non marine bivalvia ,likely : Anthraconauta or Anthraconaia ,very nice ..... congratulations bruno Link to comment Share on other sites More sharing options...

Did you note that the scale is very different for diff. pics, not only 1 cm, but up to 4 or 5. This is my first lacustrine (fresh water) finding. I'm happy.

Shamalama Posted June 22, 2009 Share Posted June 22, 2009 Very cool looking. There must have been a short term rise in the level of the swamp that allowed the bivalves to colonize. Makes for a nice example of the constantly fluctuating sea level. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Terry Dactyll Posted June 23, 2009 Share Posted June 23, 2009 RomanK..... we have an identical layer over here in the North West of England...... the 'less shelly stuff' of the same layer has produced fish fossils if you split it down.... probably from a slightly deeper area of the delta where the bivalves could been crushed and eaten by fish.... ive found ' fish or shark regurgitates' containing these small shells.... I know they give these coal seams many names, but with geological faults and such ...many are probably the same layer.... Varying in thickness as they would naturally do through erosion and varying levels of deposition of plant material....Ive noticed it in situ and it sits right above a coal seam.... so right after the area was heavily forested for a period to create the peat & coal.... It was a shallow muddy lagoon or river.... ideal for theses bivalves to flourish.... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...

And a lot of small concretions, possibly around the shells. Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...

docdutronc Posted June 23, 2009 Share Posted June 23, 2009 Hi Roman These levels limnic fauna (freshwater) are conducive to the discovery of the fauna . So in the aera of LIEVIN in northern France in shales with anthraconauta and anthraconia ,euestheria sometimes contain arthropod kind Euproops , made carefully and be vigilant in your levels of fauna you might find similar animals , perhaps one day you will be happy to find a Valloisella( my limule ) ,because this small animal has a cosmopolitan distribution in Europe, it was found by an amateur in Poland (Silesia).... best regards bruno Link to comment Share on other sites More sharing options...
docdutronc Posted June 23, 2009 Share Posted June 23, 2009 the specimen in Poland: valloisella it is exceptional we can see the 'coxa', it is in a ventral position .....I wish you much luck Roman , and I encourage you to continue searching in these shales .......

Bruno, I'm very happy to discuss with you al my last findings. This is very specific case. That specs are not from conical coal tip, they are from separate heaps placed after the mine was closed.
