“…It is noteworthy that two novel types of delthyrial cover plate that were never present in the Paleozoic spiriferids occurred in the Triassic spiriferiformis. Neocyrtina developed a peculiar delthyrial cover plate that consisted of two parts: imbricating plates near the hingeline and irregular solid nodules apically, and it was thought to have lived with the ventral umbo attached to the substrate (Yang and Xu 1966; Chen et al 2018). Several Triassic taxa, for example, Thecocyrtelloidea tubulosa and Bittnerula zitteli , embraced special deltidia ornamented with “tubular spines.” These spiriferinids may possess “pedicle fibers” extending from fine tubes to support the shell above the sediment (Yang and Xu 1966) or may have solid and tubular spines that project downward into the sediment, acting as attachment or stabilizing structures (Cowen and Rudwick 1970).…”

The Order Spiriferinida spanning the latest Ordovician to Early Jurassic is a small group of brachiopods overshadowed by other taxon-rich clades during the Paleozoic. It diversified significantly after the end-Permian extinction and became one of the four major clades of Triassic brachiopods. However, the phylogeny and recovery dynamics of this clade during the Triassic still remain unknown. Here, we present a higher-level parsimony-based phylogenetic analysis of Mesozoic spiriferinids to reveal their evolutionary relationships. Ecologically related characters are analyzed to indicate the variances in ecomorphospace occupation and disparity of spiriferinids through the Permian–Triassic (P-Tr) transition. For comparison with potential competitors of the spiriferinids, the pre-extinction spiriferids are also included in the analysis. Phylogenetic trees demonstrate that about half of the Mesozoic families appeared during the Anisian, indicating the greatest phylogenetic diversification at that time. Triassic spiriferinids reoccupied a large part of the ecomorphospace released by its competitor spiriferids during the end-Permian extinction; they also fully exploited the cyrtiniform region and developed novel lifestyles. Ecomorphologic disparity of the spiriferinids dropped greatly in the Early Triassic, but it rebounded rapidly and reached the level attained by the pre-extinction spiriferids in the Late Triassic. The replacement in ecomorphospace occupation between spiriferids and spiriferinids during the P-Tr transition clearly indicates that the empty ecomorphospace released by the extinction of Permian spiriferids was one of the important drivers for the diversification of the Triassic spiriferinids. The Spiriferinida took over the empty ecomorphospace and had the opportunity to flourish.

“…Of these, the Qingyan section of Guizhou Province, southwestern China is one of the most classic and important Anisian (early Middle Triassic) fossil localities, worldwide. A total of more than 300 species belonging to 17 fossil groups: bivalves, brachiopods, gastropods, ammonoids, corals, crinoids, echinoids, nautiloids, ostracods, scaphopods, annelids, bryozoans, cnidarians, foraminifers, conodonts, sponges, and calcareous algae have been described from this locality since the 1900s (Koken 1900;Hsu & Chen 1943;Wang 1955a, b;Wang et al 1964;Feng & Jiang 1978;Gan & Yin 1978;Liao 1978;Kristan-Tollmann 1983a, b;Yin & Yochelson 1983a, b, c;Deng & Kong 1984, 2005He 1984;Qi 1984;Qi & Stanley 1989;Stiller 1995Stiller , 1997Stiller , 1998Stiller , 1999Stiller , 2000Stiller , 2001aKomatsu et al 2004;Yao et al 2004;Deng 2006;Stiller & Bucher 2008;Wu et al 2008;Ji et al 2011;Song et al 2015;Chen et al 2018). The Qingyan fauna has become an important window on the recovery of marine ecosystems (Chen et al , 2019Chen & Benton 2012;Dineen et al 2015).…”

“…Later, several brachiopod species have been briefly described or listed in the literature (Hsu & Chen 1943;Wang 1955a, b;Wang et al 1964). The Qingyan brachiopods were not systematically described until 1966 when Yang & Xu described 29 species (and subspecies) assigned to 23 genera from the Qingyan area (Chen et al 2018). However, the taxonomy of the Qingyan brachiopod with thin marls to argillaceous limestone (Stiller 1997;).…”

“…However, the causes for this catastrophe remain controversial. The previous studies on shallow‐sea facies successions around the Palaeo‐Tethyan regions suggested that extreme global warming and an eruption of the massive Siberian flood basalts may have caused biotic mass extinction in the end of the Permian (Burgess, Muirhead, & Bowring, 2017; Chen et al, 2013; Chen, Zhao, Wang, Luo, & Guo, 2018; Grasby et al, 2017; Joachimski et al, 2012; Romano et al, 2013; Sun et al, 2012; Wang et al, 2018). On the other hand, the deep‐sea sedimentary rocks in the superocean Panthalassa are presumed to record a mass extinction associated with a deep‐sea anoxic event near the Permian–Triassic (P–Tr) transition (Isozaki, 1997).…”

We examined the lithostratigraphy and deformation structures of the accreted pelagic rocks in Lake Hamana area, Central Japan, based on a detailed field mapping and the radiolarian ages. The constructed lithostratigraphy is composed of Lopingian (Upper Permian) grey chert, black chert, black claystone with a high carbon content of 4.85-6.78 wt%, siliceous claystone, black chert, and Anisian (Middle Triassic) grey chert, in the ascending order. The symmetry in the lithostratigraphy and the change in the radiolarian ages with respect to black carbonaceous claystone are presumed to represent a deep-sea anoxic event that occurred across the Permian-Triassic (P-Tr) boundary. The P-Tr boundary black carbonaceous claystone suffered from an intense shear, resulting in blocks of siliceous claystone in the scaly black claystone matrix. In places, the sheared terrigenous rocks composed of sandstone blocks in the mudstone matrix are intercalated into the pelagic rocks, possibly representing complex mélange forming processes during the development of the Jurassic accretionary complex.
