Abstract
    Acritarch assemblages are described here for the first time from the Early Ordovician Yinzhubu and Ningkuo formations of the Nanba section (Yiyang region, Hunan province, South China). Independent stratigraphical control is provided by co-occurring late Tremadocian-early Floian (early Arenig) graptolite and chitinozoan biozones. A very diverse association of 33 species attributed to 23 genera is identified, and three acritarch assemblage zones are distinguished. These are comparable to coeval assemblages from several localities worldwide. During the Early Ordovician the Yiyang area was at low latitudes. The acritarch association interestingly shows a mixed character, comprising typical taxa from both cold-water and warm-water paleobioprovinces.
