Abstract. High-resolution sampling was performed on four Permian sections in Guangxi Province, South China (Gujingling, Sanpaoling, Guoyuan and Yutouling sections). We report abundant and well-preserved Guadalupian–Lopingian radiolarian assemblages, with 25 species belonging to three genera of the order Albaillellaria. Among them, the most abundant genus is Follicucullus with 17 species: F. bipartitus, F. charveti, F. sp. cf. F. charveti, F. dilatatus, F. falx, F. sp. cf. F. falx, F. guangxiensis, F. hamatus, F. monacanthus, F. sp. cf. F. monacanthus, F. orthogonus, F. sp. cf. F. orthogonus, F. porrectus, F. scholasticus, F. sp. cf. F. scholasticus, F. ventricosus and F. sp. cf. F. ventricosus. On the basis of composite stratigraphic ranges, this study suggests four Interval Zones in ascending order, namely F. monacanthus, F. porrectus, F. scholasticus and F. charveti Interval Zones. We provide a phylogenetic model for Follicucullus based on their morphological affinities and stratigraphic distribution. The genus Follicucullus originated from Pseudoalbaillella fusiformis, with F. monacanthus as the forerunner species from which two contemporary species then radiated: F. dilatatus and F. porrectus. Follicucullus porrectus is a long-lasting species, it is abundant in our material and several Follicucullus lineages originated from it. In terms of evolution it is considered to be the ancestor of a number of Follicucullus species.

High-resolution Holocene marine sediment records are limited, which hampers our understanding of paleomonsoon evolution. Continental shelf sediment records are derived mainly from terrestrial weathering products and are thus often sensitive to paleoclimate variations. In this study, the grain size and magnetic mineral composition of a well-dated sediment core (YJ Core) from the northern inner shelf of the South China Sea (SCS) were analyzed to provide a high-resolution record of the Holocene evolution of the East Asian summer monsoon (EASM). These magnetic and grain size records indicate that EASM intensity followed a general declining trend between approximately 6800 and 2000 cal yr BP. This general pattern is synchronous with other geologic archives from monsoon regions, and can be attributed to solar radiation forcing in the Northern Hemisphere. On centennial timescales, a weak EASM closely coincides with periods of weak solar activity. In addition, spectral analysis of clays reveals five prominent cycles, with periodicities of approximately 364, 202, 158, 119, and 104 years, which correspond to solar activity cycles. The similarities between the cyclicities of the Asian monsoon signal in sedimentary records and those of solar activity demonstrate that solar forcing has a relatively large influence on the centennial-scale variability of the EASM.
