Summary

Descripción general del contenido del recurso.

Impression fossils of ovuliferous fructifi cations from the Permian La Golondrina Formation in Santa Cruz, Argentina, are described, their affi nities compared, and fi nally, assigned to the Arberiaceae (Glossopteridales). Based on morphological differences from the genera in Arberiaceae, a new taxon is established for some specimens, whereas others are allocated to Arberia madagascariensis (Appert) Anderson & Anderson. This is the fi rst record of Arberiaceae from the La Golondrina Basin. The biostratigraphic implications of the occurrence of this family in this unit are discussed, and suggest that more evidence other than that provided by the megafl oral elements is needed to resolve the age of the constituent members of the La Golondrina Formation. São descritos impressões fósseis de fruti fi cações femininas provenientes da Formação La Golondrina, Permiano de Santa Cruz (Argentina), atribuídas a Arberiaceae (Glossopteridales), segundo a comparação de suas a fi nidades. Com base nas diferenças morfológicas dos gêneros da Família Arberiaceae, um novo táxon é proposto, enquanto as outras amostras são alocadas em Arberia madagascariensis (Appert) Anderson & Anderson. Este é o primeiro registro de Arberiaceae na bacia do La Golondrina. As implicações bioestratigrá fi cas fornecidas pela presença deste grupo, nesta unidade, são discutidas e sugere-se que mais provas, além das fornecidas pelos elementos mega fl orísticos, são necessárias para restringir os limites de idade do membro da Formação La Golondrina.
