“…Based on studies of Ito et al (), Xia et al (), and L. Zhang et al (), the basal part of this zone is marked by the absence of Follicucullus monacanthus and the presence of Follicucullus scholasticus/Follicucullus porrectus . Sample Cik‐4 in the Cikrik section consists of Follicucullus scholasticus in addition to Latentifistularia (Table ) and is assigned to this zone.…”

“…Similar to this assemblage, sample Kar‐SW‐22, Kar‐SW‐24, and Kar‐SW‐25 in the Karincali‐Southwest section (Table ) contains some Latentifistularia in addition to F. monacanthus (Figure (32,33)). These assemblages are best correlative to the Follicucullus monacanthus Zone indicating roughly middle Guadalupian age (Ishiga, , ; Ito, Feng, & Matsuoka, ; Ito et al, ; Kuwahara et al, ; Y. J. Wang et al, , , ; A. Yao & Kuwahara, ). Recent work (Ma, Feng, Caridroit, Danelian, & Zhang, ; Xia et al, ; L. Zhang et al, ) from southern China reports that the age of this zone is Wordian based on the correlation of radiolarian assemblages to the conodont assemblages (Figure ).…”

Integrated Radiolaria, benthic foraminifera and conodont biochronology of the pelagic Permian blocks/tectonic slices and geochemistry of associated volcanic rocks from the Mersin Mélange, southern Turkey: Implications for the Permian evolution of the northern Neotethys

et al. 2018

Blocks and tectonic slices within the Mersin Mélange (southern Turkey), which are of Northern Neotethyan origin (Izmir–Ankara–Erzincan Ocean (IAE)), were studied in detail by using radiolarian, conodont, and foraminiferal assemblages on six different stratigraphic sections with well‐preserved Permian succesions. The basal part of the Permian sequence, composed of alternating chert and mudstone with basic volcanics, is assigned to the late Asselian (Early Permian) based on radiolarians. The next basaltic interval in the sequence is dated as Kungurian. The highly alkaline basic volcanics in the sequence are extremely enriched, similar to kimberlitic/lamprophyric magmas generated at continental intraplate settings. Trace element systematics suggest that these lavas were generated in a continental margin involving a metasomatized subcontinental lithospheric mantle source (SCLM). The middle part of the Permian sequences, dated by benthic foraminifera and conodont assemblages, includes detrital limestones with chert interlayers and neptunian dykes of middle Wordian to earliest Wuchiapingian age. Higher in the sequence, detrital limestones are overlain by alternating chert and mudstone with intermittent microbrecciated beds of early Wuchiapingian to middle Changhsingian (Late Permian) age based on the radiolarians. A large negative shift at the base of the Lopingian at the upper part of section is correlated to negative shifts at the Guadalupian/Lopingian boundary associated with the end‐Guadalupian mass extinction event. All these findings indicate that a continental rift system associated with a possible mantle plume existed during the late Early to Late Permian period. This event was responsible for the rupturing of the northern Gondwanan margin related to the opening of the IAE Ocean. When the deep basinal features of the Early Permian volcano‐sedimentary sequence are considered, the proto IAE oceanic crust formed possibly before the end of the Permian. This, in turn, suggests that the opening of the IAE Ocean dates back to as early as the Permian.

Some taxa of the order Albaillellaria (radiolaria) are dimorphic with normal and swollen types. This study observed and biometrically analyzed the normal and swollen types of Albaillella sinuata Ishiga and Watase from a red chert bed of the Waji section of Ie Island, Okinawa Prefecture, Japan. The distribution of the slimness of the shell body of A. sinuata is bimodal, indicating that the normal and swollen types are clearly dividable. The observational and biometric results indicate that the swollen‐type A. sinuata is characterized by a swollen apical portion and a shorter overall height compared to the normal‐type A. sinuata. Meanwhile, there is no clear difference in the width of the basal part of the shell between the normal and swollen types. Dimorphism composed of the normal and swollen types is recognized within several lineages of the Albaillellaria by a compilation of previous reports of the swollen‐type occurrences in the Permian. Therefore, the dimorphism is a common phenomenon that extends beyond the families within the Permian Albaillellaria.
