“…The correlations outlined above suggest that the mid-Zambezi upper Madumabisa Formation palynoflora closely corresponds with that of the Lower Daptocephalus Assemblage Zone (sensu Viglietti et al, 2016) of the main Karoo Basin, which encompasses the lower and middle Balfour Formation, rather than the underlying Cistecephalus AZ. Unfortunately, as productive pollen samples were not obtained from within the Madumabisa Mudstone vertebrate-bearing beds, the individual faunal assemblages cannot be assigned to South African assemblage zones based on palynology.…”

“…However, based on the newly revised stratigraphic ranges in the main Karoo Basin (Viglietti et al, 2016), the upper Madumabisa Formation in the Luangwa Basin can probably be correlated to near the Cistecephalus-Daptocephalus zone boundary or even possibly into the Daptocephalus zone (although this would require later survival of Endothiodon in Zambia). Based on the occurrence of dinocephalians fossils, Sidor et al (2014) suggested that the middle of the Madumabisa Formation in the mid-Zambezi Basin was probably Guadalupian in age.…”

“…The Guodikeng Formation is also noteworthy in recording an overlap in the stratigraphic ranges of the dicynodontoid Jimusaria and Lystrosaurus (e.g., Young, 1939;Cheng, 1993;Lucas, 1993Lucas, , 2001Metcalfe et al, 2009). This relationship resembles the overlapping stratigraphic ranges of Lystrosaurus and the dicynodontoids Dicynodon, Daptocephalus, and Dinanomodon in the latest Permian of the Karoo Basin (e.g., Smith, 1995;Smith and BothaBrink, 2014;Viglietti et al, 2016).…”

“…Angielczyk et al (2014b) correlated the fauna with the Cistecephalus Assemblage Zone of the Karoo Basin. Taking into account the biostratigraphic revision of Viglietti et al (2016), which moved the lower boundary of the Daptocephalus Assemblage Zone of the Karoo Basin downwards, it is now likely that the Upper Madumabisa Mudstone Formation fauna correlates with parts of the Cistecephalus and lower Daptocephalus zones.…”

“…The remaining 1% is subdivided among medium-sized carnivores (cynodonts and biarmosuchians), small-sized fish-eating amphibians (temnospondyls), and neodiapsids (Smith et al, 2012). Smith et al (2012) tabulated data for the then-current Dicynodon Assemblage Zone, which corresponds to the lower Daptocephalus pro parte and upper Daptocephalus Assemblage Zones of Viglietti et al (2016), assigned to late Wuchiapingian to Changhsingian time. This assemblage, in comparison to that of the Cistecephalus Assemblage Zone, has fewer medium-sized herbivores such as dicynodonts (77%), but higher percentages of small and large carnivores such as gorgonopsians (3%); therocephalians (9%), and comparable numbers of large herbivorous parareptilians (3%), and medium-sized carnivorous cynodonts (5%).…”

Keywords:Tetrapoda flora phytoprovinces plant-insect interactions climate endemism latitudinal diversity gradient A B S T R A C TThe late Palaeozoic is a pivotal period for the evolution of terrestrial ecosystems. Generalised warming and aridification trends resulted in profound floral and faunal turnover as well as increased levels of endemism. The patchiness of well-preserved, late Permian terrestrial ecosystems, however, complicates attempts to reconstruct a coherent, global scenario. In this paper, we provide a new reconstruction of the Bletterbach Biota (Southern Alps, NE Italy), which constitutes a unique, low-latitude record of Lopingian life on land. We also integrate floral, faunal (from skeletal and footprint studies), and plant-insect interaction data, as well as global climatic interpretations, to compare the composition of the 14 best-known late Permian ecosystems. The results of this ecosystem-scale analysis provide evidence for a strong correlation between the distribution of the principal clades of tetrapod herbivores (dicynodonts, pareiasaurs, captorhinids), phytoprovinces and climatic latitudinal zonation. We show that terrestrial ecosystems were structured and provincialised at high taxonomic levels by climate regions, and that latitudinal distribution is a key predictor of ecosystem compositional affinity. A latitudinal diversity gradient characterised by decreasing richness towards higher latitudes is apparent: mid-to lowlatitude ecosystems had the greatest amount of high-level taxonomic diversity, whereas those from high latitudes were dominated by small numbers of higher taxa. The high diversities of tropical ecosystems stem from their inclusion of a mixture of late-occurring holdovers from the early Permian, early members of clades that come to prominence in the Triassic, and contemporary taxa that are also represented in higher latitude assemblages. A variety of evidence suggests that the Permian tropics acted as both a cradle (an area with high origination rates) and museum (an area with low extinction rates) for biodiversity.

Biostratigraphic significance and geometric morphometrics of Euestheria gutta (Crustacea: Branchiopoda: Spinicaudata): An index fossil of continental Permian–Triassic transitional beds

The Permian-Triassic mass extinction was the largest biotic extinction event in the Phanerozoic and affected both marine and continental life. Marine Permian-Triassic transitional sequences can be correlated in many regions, but this has proved difficult for continental successions. A growing number of studies show that spinicaudatans are some of the most common fossils in continental strata and can be used as index fossils for continental stratigraphic division and correlation. Here we document the morphology and biostratigraphic significance of Euestheria gutta based on wellpreserved fossils from southwestern China. It shows strong intraspecific morphological variation, while the most important feature is the strongly convex larval valve and significant finely pitted to weakly reticulated ornamentation on the growth bands.Evidence from palaeobotany, charcoal, and organic carbon isotopes indicated that the continental mass extinction in southwestern China was marked by the catastrophic loss of tropical rainforest vegetation, enhanced wildfire and a negative carbon isotope excursion (CIE) during the P-Tr transition. Meanwhile, abundant E. gutta first appeared at the onset of the negative CIE and just above the horizon of the loss of macroflora. Based on the global geographic distribution of E. gutta and temporal correlation, we conclude that this species existed from the latest Permian to the earliest Triassic, and the occurrence of E. gutta could be used as an index fossil of the continental mass extinction interval or P-Tr transitional beds.
