Abstract
Abstract The Dinwoody Formation of the western United States represents an important archive of Early Triassic ecosystems in the immediate aftermath of the end-Permian mass extinction. We present a systematic description and a quantitative paleoecological analysis of its benthic faunas in order to reconstruct benthic associations and to explore the temporal and spatial variations of diversity, ecological structure and taxonomic composition throughout the earliest Triassic of the western United States. A total of 15 bivalve species, two gastropod species, and two brachiopod species are recognized in the study area. The paleoecological analysis shows that the oldest Dinwoody communities are characterized by low diversity, low ecological complexity and high dominance of few species. We suggest that this low diversity most likely reflects the consequences of the mass extinction in the first place and not necessarily the persistence of environmental stress. Whereas this diversity pattern persists into younger ...

The recovery from the end-Permian mass extinction event was a key interval in the history of life, but few modern studies provide systematic data on benthic marine faunas from the epoch immediately following the crisis. Here, the bivalve fauna from the early Spathian (Olenekian, late Early Triassic) Virgin Limestone Member of the Moenkopi Formation is comprehensively documented for the first time. The new genus Sementiconcha (Myophoricardiidae), type species Sementiconcha recuperator sp. nov., a...

Based on newly collected material from the uppermost Smithian and lower to middle Spathian (Oleneki- an, Lower Triassic) of the Salt Range and Surghar Range (Pakistan), 15 bivalve species belonging to 11 genera are described, including two new genera, Eobuchia and Dimor- phoconcha , and one new species, Palaeoneilo ? fortistriata . Eo- buchia gen. nov. is placed in a new subfamily, the Eobuchiinae, which differs from the Buchiinae in having an almost planar and only moderately inclined or offset...

Patterns of taxonomic and ecologic selectivity are the most direct record of processes infl uencing survival during background and mass extinctions. The Guadalupian (Capitanian) and end-Permian (Changhsingian) extinctions have both been linked to environmental degradation from eruption of large fl ood basalts; however, the extent to which taxonomic selectivity conforms to the expected stresses remains incompletely understood because many of the relevant biological traits are mutually correlated....

Abstract New ichnological data from the Lower Triassic Werfen Formation (Dolomites, Italy) revealed an unexpectedly diverse and complex ichnofauna in mixed siliclastic–carbonate shelf sediments of the western tropical Tethys shortly after the end-Permian mass extinction event. Common elements are Thalassinoides , Palaeophycus and Planolites . Other associated ichnogenera include Spongeliomorpha , Rhizocorallium , Lockeia , Catenichnus , Helminthopsis , and Taenidium . One structure is tentativel...

Abstract The bilaterally symmetrical gastropods grouped in the extinct superfamily Bellerophontoidea are considered as a typical Early Triassic example of Dead Clade Walking. They survived the Permian–Triassic extinction but disappeared in the Early Triassic. We analysed all Triassic occurrences of bellerophontoideans known from the literature and revised their taxonomic assignment and stratigraphic occurrence. We confirm eight Early Triassic species of Bellerophontoidea representing three gener...

A well-preserved ammonoid fauna of Early Dienerian age has long been known from the lower portion of the Candelaria Formation in the old Candelaria silver mining district in Mineral and Esmeralda Counties, Nevada, but for a number of reasons, this fauna has never been studied in detail nor illustrated. Previous authors assigned this ammonoid fauna to the Early Dienerian Proptychites candidus Zone of Canada. In reality, it more closely resembles the Tethyan faunas than the higher palaeolatitude C...

Abstract Studies aimed at understanding the recovery from the end-Permian mass extinction have focused on the distribution of faunas, trace fossils, and microbialites across depositional environments, but few have examined how these individual ecologic components relate to one another, especially the latter relationship between microbialites and trace fossils, which appear to be mutually exclusive. Microbialites occur throughout Lower Triassic strata primarily in two different forms depending on...

A single carbonate coquinoid lens from the Griesbachian (Early Triassic) of Shanggan, South China, yielded 11 bivalve species described in this study in addition to four gastropod and one ammonoid species reported elsewhere. This makes the Shanggan fauna one of the richest mollusc faunas from the early post-extinction interval after the end-Permian mass extinction event. Four of the present genera are long-term survivors, five are holdovers that went extinct at the end of the Griesbachian or lat...

The Dapingian to Darriwilian Kanosh Formation is one of the most fossiliferous units of the Pogonip Group (Great Basin, western US). It records a critical phase of the so-called Great Ordovician Biodiversification Event (GOBE) during which many marine clades diversified on lower systematic levels. However, a comprehensive palaeoecological analysis has not been presented for this unit so far. Based on newly collected material from three sections in the type area at Ibex, we reconstruct benthic ma...

Abstract Research on the Permian-Triassic boundary (PTB) along the northern margins of Pangaea (exposed today in the Arctic region) has been heavily reliant on field observations, where data resolution was consequently determined by outcrop condition and accessibility. Core drilling in central Spitsbergen allowed for a near-complete recovery of two ~90 m cores through the PTB. Analyses of the core and nearby outcrops include stratigraphic logging and sampling, XRF scanning, petrography, biostrat...

Abstract Mass extinction events are characterized by major losses in faunal diversity and are associated with several other ecological effects, e.g., reductions in tiering, selective losses of ecological lifestyles, and body size reductions. The latter has received considerable attention and debate, as to whether the reduced size of post-extinction organisms is due to the selective extinction of large species, absence of large species as a stochastic effect of low-diversity faunas (the Gulliver ...

Abstract The discovery of a Permian-Triassic boundary section in northeastern Utah provided an opportunity to study the chemistry and geology associated with this event that led to one of the greatest mass extinctions on the planet. From 83% to 97% of the species living on the planet went extinct during this relatively short interval of geological time that defines the major geological boundary between the Paleozoic and Mesozoic Eras. The cause and resulting sequence of events that led to this e...

Abstract Widespread Lower Triassic microbial carbonates occur after the end-Permian mass extinction (EPME) and are commonly attributed to reduced metazoan competition after the EPME, or to paleoceanographic conditions that suppressed metazoan abundance and increased ocean carbonate saturation. Testing these hypotheses requires direct spatial (versus temporal) linkages between Lower Triassic microbial deposits and lithologic or geochemical proxy evidence for environmental perturbations. This stud...

Abstract Immediately after the latest Permian mass extinction, bivalve faunas colonized the Permian-Triassic Transitional Beds (PTTB), especially in littoral clastic facies of South China. The Permian-Triassic (P-Tr) transitional bivalve fauna is composed of holdovers, long-term survivors and newly evolved taxa, and characterized by moderate diversity and high dominance. However, the taxonomy and ecology of this bivalve fauna of littoral clastic facies have not been well understood, especially i...

The Schlern and Seiser Alm area (South Tyrol, Italy) is a classical locality for studies of Middle Triassic platform to basin transitions, yet details of the palaeoecology of the rich benthic faunas of this area have been insufficiently known. We present herein a detailed palaeoecological study of the fauna from the Schlernplateau beds (Late Ladinian to Early Carnian) and the more or less time-equivalent Pachycardientuffe (Late Ladinian), which is based on quantitative faunal data. Both the pala...
