Notes On The Early Devonian Brachiopod Leptaena Ouralensis De Verneuil, 1845, Anthony J. Wright

Anthony Wright

On the basis of the type material, an attempt is made to review the widely reported brachiopod Leptaena ouralensis de Verneuil, 1845, much more commonly known as Megastrophia uralensis (de Verneuil, 1845). Assignment of this species to Megastrophia is still tentative, and many reports of the species, especially those based on crack-out material, must remain doubtful. The species has an established narrow geographic and stratigraphic range to the upper Emsian (upper Lower Devonian) of mostly Siberia, Mongolia and China.
