A Highly Diverse Olenekian Brachiopod Fauna from the Nanpanjiang Basin, South China, and Its Implications for the Early Triassic Biotic Recovery [PDF]
Biology, 2023 As one of the predominant benthic organisms in the Palaeozoic, brachiopod was largely eliminated in the Permian–Triassic boundary mass extinction, and then highly diversified in the Middle Triassic.

Early Triassic marine biotic recovery: the predators' perspective. [PDF]
PLoS ONE, 2014 Examining the geological past of our planet allows us to study periods of severe climatic and biological crises and recoveries, biotic and abiotic ecosystem fluctuations, and faunal and floral turnovers through time. Furthermore, the recovery dynamics of

Mercury anomalies and the timing of biotic recovery following the end-Triassic mass extinction [PDF]
Nature Communications, 2016 The association between Central Atlantic Magmatic Province (CAMP) eruption volatiles and the end-Triassic mass extinction remains ambiguous. Here, the authors present mercury and palaeontological evidence from the same archive and show that significant ...

Recurrent and Long-Term Oceanic Anoxia Contributed to Aborted Biotic Recovery Following the Permian–Triassic Crisis [PDF]
BiologyThe influence of ocean chemistry on Early Triassic biotic recovery is poorly understood in the Chaohu Area. Here, we evaluate the influence of ocean chemistry following the Permian–Triassic crisis using pyrite content, δ13Corg, and S isotopic composition

Negative resistance and resilience: biotic mechanisms underpin delayed biological recovery in stream restoration [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2021 Traditionally, resistance and resilience are associated with good ecological health, often underpinning restoration goals. However, degraded ecosystems can also be highly resistant and resilient, making restoration difficult: degraded communities often become dominated by hyper-tolerant species, preventing recolonization and resulting in low ...

Dynamics of the Largest Carbon Isotope Excursion During the Early Triassic Biotic Recovery [PDF]
Frontiers in Earth Science, 2020 The dynamics of the carbon cycle across different timescales is crucial for understanding past and present global climate changes. Following the Permian–Triassic boundary mass extinction (PTBME), the carbon cycle changed profoundly during the following 5.

Nature and timing of biotic recovery in Antarctic benthic marine ecosystems following the Cretaceous–Palaeogene mass extinction [PDF]
Palaeontology, 2019 AbstractTaxonomic and ecological recovery from the Cretaceous–Palaeogene (K–Pg) mass extinction 66 million years ago shaped the composition and structure of modern ecosystems. The timing and nature of recovery has been linked to many factors including palaeolatitude, geographical range, the ecology of survivors, incumbency and palaeoenvironmental ...

Comptes Rendus Palevol, 2005 Abstract Microgastropod-dominated shell beds formed during the aftermath of the end-Permian mass extinction comprise a characteristic Early Triassic biofacies. The identification of this biofacies is significant: (1) no other episode in the geologic record is characterized by the lack of larger gastropods and abundant, conspicuous microgastropod ...

A new perleidid neopterygian fish from the Early Triassic (Dienerian, Induan) of South China, with a reassessment of the relationships of Perleidiformes [PDF]
PeerJ, 2022 Neopterygii is the largest clade of ray-finned fishes, including Teleostei, Holostei, and their closely related fossil taxa. This clade was first documented in the Early Carboniferous and underwent rapid evolutionary radiation during the Early to Middle ...
