The taxonomic diversity dynamics of pterygote insects in the Permian and Triassic at the family/age level are considered. Different metrics of taxonomic diversity are compared. Biogeographic and taphonomic aspects of changes in the composition of insect faunas in the Permian and about the P-T transition are discussed. Some changes in the Permian insect faunas are of a biogeographic nature and do not indicate global changes in diversity. Insects with aquatic immatures were rather common in the… 
Insect recovery after the Permian/Triassic crisis
Three main stages of insect fauna development in the Triassic are outlined: Early Triassic survival (‘post-Paleozoic’); Anisian–Carnian acme (‘Triassic sensu genuino’); Carnian–norian rise of the
The Lopingian of Australasia: a review of biostratigraphy, correlations, palaeogeography and palaeobiogeography
This paper presents an overview of the space and time distributions of Lopingian strata and biotas in Australia, New Zealand, Timor and New Caledonia. Based on this review, we propose a new schematic
Insects from a new Ufimian locality of Troitsa in the Perm Region, Russia
It is shown that, among Ufimian insect assemblages of the Perm Region, Troitza is more similar to the later Vorkuta locality than to Tyul’kino, which is of the same age as Troitsa.
New Blattinopsidae (Insecta: Blattinopsida) in the Permian of the Pechora Basin (Komi Republic, Russia) in the Context of Landscape and Vegetation Evolution
Permian Blattinopsida in the Vorkuta Group of the Pechora Basin (Komi Republic, northern Russia) are reviewed and the taxonomic composition of plants in the Kungurian-Ufimian interval is analyzed.
Insects during the time around the Permian—Triassic crisis
Dramatic changes in ancient biotas usually interpreted as ecological crises or mass extinctions are treated in many publications of every sort, and yet our notions about such events remain
Floral Assemblages and Patterns of Insect Herbivory during the Permian to Triassic of Northeastern Italy
Generalized-to-specialized ratios show minimal change through the interval, although herbivore component community structure (herbivore species feeding on a single plant-host species) increasingly was partitioned from Wuchiapingian to Ladinian.
Latest Permian insects from Wapadsberg Pass, southern Karoo Basin, South Africa
The regional insect fauna preserved close to the Permian–Triassic boundary at Wapadsberg Pass, southern Karoo Basin of South Africa, is described, which provides a rare glimpse into insect life immediately before this global crisis.
New mayfly genera from the Middle Triassic of Poland and their evolutionary and paleogeographic implications (Ephemerida: Litophlebiidae, Vogesonymphidae).
The presence of a mayfly nymph in the last instar stage suggests not only that the Pałęgi deposit represents a fluvial environment with well-oxygenated and limpid water but also that these conditions lasted long enough to allow for such development.
New austrolimulid from Russia supports role of Early Triassic horseshoe crabs as opportunistic taxa
It is suggested that the hypertrophy or reduction in exoskeletal sections illustrate how species within the Austrolimulids family evolved as opportunistic taxa after the end-Permian extinction.


Permian Faunas of Homoptera (Hemiptera) in Relation to Phytogeography and the Permo-Triassic Crisis
Their diversification, faunal composition, geographic distribution and possible host plant associations in the Permian (including the Permo-Triassic transition) are analyzed at the family level and some peculiarities of thePermian crisis are discussed.
Insect recovery after the Permian/Triassic crisis
Three main stages of insect fauna development in the Triassic are outlined: Early Triassic survival (‘post-Paleozoic’); Anisian–Carnian acme (‘Triassic sensu genuino’); Carnian–norian rise of the
Triassic Floras Of Eurasia
Accurate knowledge of the Triassic floras is essential for the reconstruction of the history of life on the Earth. They are important for progress in geological surveys and research because petroleum
Narrow-armored Chroniosuchians (Amphibia, Anthracosauromorpha) from the Late Permian of Eastern Europe
The Permian and Triassic chroniosuchians are revised and the morphology of the dorsal armor scutes is discussed in detail. The first narrow-armored chroniosuchid Uralerpeton tverdochlebovae from the
Vyazniki biotic assemblage of the terminal Permian
A new unique and diverse biotic assemblage of the terminal Permian has recently been discovered in the town of Vyazniki (Central Russia). The Vyazniki terrestrial community is transitional between
Permian Insects of the Vorkuta Group in the Pechora Basin, and Their Stratigraphic Implications
The results are inconsistent with the hypothesis of considerable age difference between parts of the Vorkuta Group section, although they do not help with dating the deposits within the Kungurian through Kazanian interval.
Permian insects from the Beaufort Group of Natal, South Africa
The Odonata and Trichoptera are reported for the first time; specimens are assigned to three known genera not previously recorded in South Africa; eight new species are descriptionbed, two in new genera.
Changes in terrestrial biota before the Permian-Triassic ecological crisis
The period around the Permian-Triassic boundary was marked by one of the most important and interesting events in the evolution of life. The diversity of both marine and continental biotas decreased.
Insect origination and extinction in the Phanerozoic
Abstract Insects (Superclass Hexapoda) are the most successful group of living terrestrial arthropods and the richness of their fossil record is only just beginning to be realized with the recent
The geological setting and palaeoenvironmental and palaeoecological reconstructions of the Upper Permian insect beds at Belmont, New South Wales, Australia
The entomofauna of the Tatarian insect beds within the Newcastle Coal Measures at Belmont, north of Sydney, was described many years ago. A new collection contains some undescribed species,
