  • Description: <jats:p>A new genus <jats:italic>Ibergirhynchia</jats:italic>, a member of the rhynchonellide superfamily Dimerelloidea, is described for the species <jats:italic>Terebratula contraria</jats:italic> Roemer, 1850, from Early Carboniferous deposits of the Harz Mountains, Germany. <jats:italic>Ibergirhynchia contraria</jats:italic> is from a monospecific brachiopod limestone that formed on top of the drowned Devonian Iberg Reef which persisted as a seamount during Famennian and Early Carboniferous times. <jats:italic>Ibergirhynchia contraria</jats:italic> is considered a cold seep-related brachiopod based on this locality. Such seep associations have been observed for Mesozoic representatives of the rhynchonellide superfamily Dimerelloidea. <jats:italic>Ibergirhynchia</jats:italic> is considered the first Paleozoic representative of the family Rhynchonellinidae. <jats:italic>Ibergirhynchia</jats:italic> resembles <jats:italic>Dzieduszyckia</jats:italic> externally and may be derived from this dimerelloid.</jats:p>
