OCURRENCE OF LINGULAPHOLIS (CRANIOPSIDAE, BRACHIOPODA) IN THE PIMENTEIRA FORMATION (DEVONIAN, PARNAÍBA BASIN): Registro de Lingulapholis (Craniopsidae, Brachiopoda) na Formação Pimenteira (Devoniano, Bacia de Parnaíba)

The genus Lingulapholis had temporal and spatial restrictions during the Devonian, being found only in Colombia and the United States. In Brazil, its related taxa Craniops is common in the Amazonas, Paraná, and Parnaíba basins. New data from the cities of Picos and Itainópolis, east flank of Parnaíba Basin, led to the discovery of a yet previously undescribed brachiopod genus for this region of Gondwana. The Lingulapholis brachiopod was found associated with plant fragments under conditions of moderate to low hydrodynamic energy as indicated by ichnological assemblage, in proximal expressions of Cruziana ichnofacies alternated to Skolithos ichnofacies. The presence of Lingulapholis suggests that the Parnaíba Basin was inserted in the zone of diffuse faunal mixing during the Middle Devonian.ABSTRACT - The genus Lingulapholis had temporal and spatial restrictions during the Devonian, being found only in Colombia and the United States.

RESUMO - - O gênero Lingulapholis teve restrições temporais e espaciais durante o Devoniano, sendo encontrado apenas na Colômbia e nos Estados Unidos. No Brasil, seu táxon relacionado Craniops é comum nas bacias do Amazonas, Paraná e Parnaíba. Novos dados das cidades de Picos e Itainópolis, flanco leste da Bacia do Parnaíba, levaram à descoberta de um gênero de braquiópode ainda não descrito para esta região do Gondwana. O braquiópode Lingulapholis foi encontrado associado a fragmentos de plantas em condições de moderada a baixa energia hidrodinâmica, conforme indicado pela assembleia icnológica, em expressões próximas de icnofácies Cruziana alternadas a icnofácies Skolithos. A presença de Lingulapholis sugere que a Bacia do Parnaíba esteve inserida na zona de mistura faunística difusa durante o Devoniano Médio

First occurrence of Lingulepis (Brachiopoda-Obolidae) from the Devonian of the Paraná state, Brazil

The brachiopod fauna of the Paraná State Devonian sucession (Neo-Lochkovian – Frasnian) is known for a long time. In the present paper a new species of Brachiopoda, Lingulepis wagoneri sp. nov. (Linguliformea – Lingulata – Obolidae) is recorded and described for the Paraná Basin Devonian. It is the first occurrence of this genus in Brazil. All specimens were preserved in siltstone shale and dark-gray siltstone and were collected in Ponta Grossa and Tibagi outcrops, located in the eastern portion of the Paraná Basin
