1. Nº 33 – The Palaeozoic Ammonoids of the South Portuguese Zone
Resumo: The present publication on the Paleozoic ammonoids of South Portugal represents the end of a long story that concerns almost a century of discontinuous ammonoid research. As wich many other fields of Paleozoic Portuguese geology, it was Nery Delgado who kicked things off at the end of the last century. He provided the faunas that enabled the first determinations to be made by Roemer and Pruvost.
