Resum

The new divisions from the global scale for the Ordovician System, except for the Tremadocian and Hirnantian stages, are difficult to correlate in the Iberian Ordovician, because their GSSPs involve deep-water facies and faunas not recorded in the shallow, high-paleolatitudinal settings of the peri-Gondwanan area. Previously to the Global scale, the British-Avalonian regional scale had been widely adopted in the Iberian Ordovician during all the 20th Century, but there are serious correlation problems due to the former’s conceptual evolution and variable criteria used for the British type areas during the last 40 years. However, the use of the Bohemo-Iberian scale instead, provides better precision to Iberian correlations, because it is based in some local biostratigraphical and biochronological markers, widely recorded over an extensive area of the European and North African peri-Gondwanan margin. The Bohemo-Iberian scale shows episodic links with other regional scales, which will provide indirect correlations also with the global Ordovician scale.
