Ribeiria pholadiformis Sharpe in Ribeiro (Rostroconchia): história do estudo, localidade e unidade-tipo e a coleção topotípica inédita do Museu Geológico de Portugal
No full textABSTRACT: Ribeiria pholadiformis Sharpe in Ribeiro, the type-species of Ribeirioida (Rostroconcha), was erected almost 170 years ago, based on portuguese fossils from the Middle Ordovician of the Buçaco Syncline. In this paper, we review the history of the study of this species and clarify the type-locality and unit for this taxon: the Cácemes Group (Darriwilian) in the Palheiros stream section (Penacova). The reconstitution of Sharpe’s original label led to discover that one of the paralectotypes is the external mould of the lectotype, being this specimen now divided between the Geological Survey Museum, Keyworth (the latter) and the Natural History Museum, London (the former). Furthermore, we report an unpublished collection of 25 specimens of topotypic material, gathered during the 19th century under the guidance of Nery Delgado, deposited in the Geological Museum of Portugal. Its study will allow assessing the morphological variability of the species for the first time.RESUMO: Ribeiria pholadiformis Sharpe in Ribeiro, a espécie-tipo de Ribeirioida (Rostroconcha), foi definida há quase 170 anos com base em fósseis portugueses do Ordovícico Médio do Sinclinal de Buçaco. Neste
artigo revemos a história do estudo desta espécie e esclarecemos qual a localidade e unidade-tipo: o Grupo Cácemes (Darriwiliano) no setor da ribeira de Palheiros (Penacova). A reconstituição da etiqueta original de
Sharpe permitiu descobrir que um dos paralectótipos é o molde externo do lectótipo, estando este espécime agora dividido entre duas instituições: o Natural History Museum, Londres (o primeiro) e o Geological Survey
Museum, Keyworth (o segundo). Adicionalmente, damos a conhecer a constituição da coleção inédita de material topotípico de R. pholadiformis do Museu Geológico de Portugal, constituída por 25 exemplares recolhidos durante a segunda metade do século XIX sob a orientação de Nery Delgado. O seu estudo permitirá avaliar a variabilidade morfológica da espécie pela primeira vez.info:eu-repo/semantics/publishedVersio
