New Carboniferous- Permian brachiopods from Klaipeda district Western Lithuania
D.N.FossilmanLithuania posted a topic in Fossil ID
Good 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. -
Carboniferous and Permian boulders in Lithuania- discovery needs confirmation!
D.N.FossilmanLithuania posted a topic in General Fossil Discussion
Dear 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). Carbon- 16 replies

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

Found as surface float on the scree pile at the Windom exposure. A very common fossil in Hamilton group sediments. Similar to Emanuella praeumbona, distinguished from E. praeumbona by the hinge width; the hinge of A. umbonata spans the width of the valve, while that of E. praeumbona is narrower. A. umbonata has a nearly flat brachial valve, while that of E. praeumbona shows a convex profile. Full-sized specimens of A. umbonata are also not as large as E. praeumbona. References: Wilson, K.
