“…Unlike some orders (e.g., Orthida, Productida, and Spiriferida) that went extinct during the crisis, the Rhynchonellida survived the P/Tr mass extinction and became the second most diverse order (after the Terebratulida) in the Mesozoic and Cenozoic (Lee 2008;Carlson 2016); they, however, were generally a more minor component of brachiopod communities during the Paleozoic (Carlson 2016). When compared with the relatively better-known, cladistically based phylogenies of other orders within the Brachiopoda (Carlson 1991a(Carlson ,b, 1993(Carlson , 1995Alvarez et al 1998;Carlson and Leighton 2001;Jaecks and Carlson 2001;Carlson and Fitzgerald 2008;Harnik et al 2014;Congreve et al 2015;Lee and Shi 2016;Guo et al 2020b), the phylogenetic evolution of this successful group across the P/Tr transition still remains poorly understood. Xu (1990) published the first cladistic analysis of some Triassic genera, based on relatively few characters, and subsequent research confirmed that morphology-based phylogeny is a powerful tool revealing the evolution of this and other groups (Carlson 1991a(Carlson ,b, 1993(Carlson , 1995Carlson and Fitzgerald 2008;Congreve et al 2015;Sclafani et al 2018;Guo et al 2020b).…”

The Rhynchonellida is a major group of brachiopods that survived the “big five” mass extinctions and flourished after the Permian/Triassic (P/Tr) crisis. However, phylogenetic and character evolution in the Rhynchonellida across the P/Tr transition is poorly understood. In view of the widespread homoplasy across this order, we employ a tip-dated Bayesian analysis to reconstruct phylogenetic relationships for late Permian–Triassic rhynchonellides. The same data were also analyzed using three other methods: undated Bayesian, equal-weighting, and implied-weighting parsimony. Compared with trees generated by other methods, those constructed by tip-dating best account for the homoplasy in this group and are closer to previous assumptions on the evolution of this order. Based on the analyses of multiple trees, the major increase in lineage richness occurred in the Early and early Middle Triassic. Also, richness in the Anisian almost reached the highest level seen in the Triassic. According to fossil records, a pronounced reduction in shell size and in the development of ornamentation occurred after the P/Tr extinction, which is largely due to the loss of large and highly sculptured genera and the diversification of small-sized and weakly ornamented genera. Ancestral-state estimation of shell size and development of ornamentation, coupled with comparisons of other characters, indicate that the Early–Middle Triassic mature “small-sized taxa” may have characters displayed by juveniles of their ancestors. This suggests that for these genera, paedomorphosis was possibly a strategy to survive and diversify in the harsh environment after the P/Tr extinction.

Antitropicality and convergent evolution: a case study of Permian neospiriferine brachiopods

Antitropical distribution is a biogeographical pattern characterized by natural occurrences of the same species or members of the same clade in the middle-or middle-to-high-latitudinal habitats of both hemispheres, either on land or in marine environments, without appearing in the intervening tropical environments. For most of the noted examples of Permian antitropical distribution, particularly in marine invertebrates, the causes of disjunctions have been mainly linked to either dispersal or vicariance models. Little attention has been paid to other possible mechanisms. This study investigated the antitropicality of some Permian neospiriferine brachiopods through detailed taxonomic revision, comparison of palaeobiogeographical distribution, and a phylogenetic analysis. Several species, previously assigned to Kaninospirifer, are here reassigned to other genera, especially to Fasciculatia in the northern hemisphere and to Quadrospira in the southern hemisphere during the Permian. Both Kaninospirifer and Fasciculatia appear to have been restricted to north-western Pangea and north-eastern Asia during the Permian, but
