D.N.FossilmanLithuania posted a topic in Fossil IDGood morning everyone. This summer I was in Klaipeda district (Western Lithuania) for several days and found some interesting brachiopod fossils in dolomite boulders that probably date back to Carboniferous- Permian times. Please help to identify genera of these brachiopod specimens, it would help much to know the precise age of each boulder. The largest brachiopod specimens are up to 3 cm length, the smallest rhynchonellid is 5 mm length.
D.N.FossilmanLithuania posted a topic in General Fossil DiscussionDear Guys, During the last several years i detected unknown truth talking about Lithuanian boulders- the Carboniferous and Permian marine rocks are very numerous and their age is various- there can be found almost each stage of Carboniferous and Permian. The main rock types are three- dolomite and limestone with masses of brachiopods that is various in color, stromatolite limestone with mollusks and unidentified cephalon like fossils, and the last- lacustrine limestone with coelacanth scales and possible plant remains (Carboniferous rhabdodermatids are very numerous). Carboniferous period and Early- Middle Permian was not known in Lithuanian glacial boulders so I very need the strong expert, especially who works on Carboniferous- Permian brachiopods. If my age determinations are correct then I will write the scientific book about this discovery and i think there is huge possibility that many of these boulders could be transported by someone glaciation from Northwestern Russia (or Northern Ural) because there are big areas of Devonian, Carboniferous, Permian and Triassic rocks near surface and Northern mountains potentially could be the cold center at some glaciation period in the Pleistocene. I will show all the pictures with fossil identifications and size, maybe someone will tell the opinion about the taxon and age possibilities. Any contact detail or other important information is very welcome! First image- Angiospirifer (Late Carboniferous), 1.1 cm length Second image- Anthracospirifer (Middle- Late Carboniferous), 1.8 cm length third image- Archaeocidaridae sea urchin plates (Carboniferous), 5- 8 mm diameter Fourth image- unidentified brachiopod species from Carboniferous- Early Permian (8 mm- 1 cm length) Fifth image- Atomodesma? bivalves from Kungurian boulder with Waagenoconcha brachiopod (1.7- 2.3 cm length)
Dear Guys, Few weeks ago I found these brachiopod remains in Klaipeda district (Western Lithuania) and I don't know which genera they belong to. I think the age should be Late Devonian or Early Carboniferous. Please help to identify these remains. Best Regards Domas
