British Cambrian acritarchs — A preliminary account
Review of Palaeobotany and Palynology, 1974Abstract A brief characterization of acritarch assemblages from sequences of known Cambrian age is presented. Cambrian acritarch assemblages have great potential for zonation and long-range correlations.

The Ordovician Arkonia-Striatotheca acritarch plexus
Review of Palaeobotany and Palynology, 1997Abstract The original diagnoses, stratigraphical ranges and geographical distribution of all infrageneric taxa attributed to the genera Arkonia Burmann 1970 and Striatotheca Burmann 1970, are critically evaluated in a review of published literature supplemented by studies of new material from Belgium and Germany, including sections from type ...

Tremadocian acritarchs from northwestern Argentina
Review of Palaeobotany and Palynology, 1997Abstract A Tremadocian acritarch assemblage is described from the Santa Rosita Formation, Cordillera Oriental, Salta Province, northwestern Argentina. The microplankton corresponds to trilobite-bearing strata assigned to the lower to upper Tremadocian from the middle part of the Santa Rosita Formation.

Early Ordovician provincialism in acritarch distribution
Review of Palaeobotany and Palynology, 1997Abstract 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 ...
