Abstract

Famatinorthis cf. F. turneri Levy and Nullo, 1973, is an abundant component of a poorly preserved brachiopod assemblage in volcaniclastic rocks at one locality in the Arenig-age Shin Brook Formation in northeastern Maine. The brachiopod assemblage of the Shin Brook Formation has been classed as a Celtic biogeographic assemblage that is interpreted to have lived in cool water at mid- to high peri-Gondwanan latitudes. Famatinorthis turneri sensu stricto is one of the six brachiopod species known from coeval volcanicsrich rocks of continental margin affinities in the Famatina Range of northwestern Argentina; the presence of its congener in Maine supports the Celtic affinities of the Famatina assemblage, but its Ordovician location remains cryptic.
