New palynomorph biostratigraphy determined the age of the unit as Llandovery and therefore synchronous with the glaciomarine record of adjacent intracratonic basins of South America. Early Silurian glaciation in South America supports the small ice-sheet hypothesis and the isotopic evidence for glaciation-related short-term climatic changes in the Early Silurian.
