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.

Key Species

Late Wenlock and Ludlow transition graptolites are better developed and more diverse in the Yulin region of Guangxi Province, South China, than elsewhere in China. The upper Homerian (upper Wenlock) graptolites, while moderately diverse, are not amenable to a zonal subdivision because key species such as Colonograptus praedeubeli, Colonograptus deubeli, and Colonograptus ludensis are found to completely overlap in their occurrences. Ludlow graptolites, all probably assignable to the lowest Ludlow nilssoni–colonus Biozone, include Lobograptus progenitor, Colonograptus colonus, Colonograptus gerhardi, and Bohemograptus bohemicus (sensu lato). The single occurrence of Monograptus cf. rectiformis Príbyl is the only species suggestive of Pridoli-age strata. The overall faunal assemblages are composed predominately of cosmopolitan species, but two species, Colonograptus gerhardi and Monograptus cf. rectiformis, provide minor support for the suggestion that the Yunkai Block in which the Yulin region is situated was originally part of Gondwanaland.
