Early Ordovician provincialism in acritarch distribution

Review of Palaeobotany and Palynology, 1997
Abstract Palynological evidence on the distribution of fossil marine microplankton corroborates presumed provincialism during the late Early Ordovician. Closely similar acritarch assemblages and other palynomorphs, namely cryptospores, were recovered from coeval sedimentary sequences within a sedimentary belt rimming the northern margin of Gondwana ...
