The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these g

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).

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 near the top of the Windom exposure, a few feet below the Genundewa Limestone at Penn-Dixie Quarry in Hamburg, NY. Distinguished from Ambocoelia umbonata by the hinge width; the hinge of A. umbonata spans the width of the valve, while that of E. praeumbona is narrower. E. praeumbona also shows a convex profile to the brachial valve, and grew to a larger size. E. praeumbona is common in the Hamilton Group only within the upper layers of the Windom Member. Originally designated Orthis praeumbona, later assigned to Ambocoelia, then reassigned to Ema
