Abstract.  In the South Portuguese Zone, sections located in the Bordeira Antiform (localities Praia de
Murraçâo, Praia das Quebradas, and Rocha da Lagoa) show a Late Viséan faunal succession of goniatites,
which principally resembles that of Northwestern and Central Europe (e. g. the Rhenish Massif).  The fol-
lowing goniatite zones were identified in Southwest Portugal: Goniatites hudsoni Zone, Goniatites spiri-
fer Zone, and the zones between the Arnsbergites gracilis Zone and the Lyrogoniatites liethensis Zone.  On
the basis of goniatites, a proposal for a subdivision of the Late Viséan into the three substages Late Viséan
A, B and C is given.
