Ongoing controversies surrounding the end-Triassic extinction highlight the need for identifying a causal mechanism leading to extinction. Bivalve data from Lombardia (Italy), Northern Calcareous Alps (Austria and Germany), and northwest Europe (England and Wales) provide the biologic signal of selective extinction to compare two competing extinction hypotheses: (1) sea-level change and associa...

The Triassic was a turning in the history of biodiversity: bracketed by two major biotic crises, characterised biotic, climatic and tectonic events, it saw transition from Palaeozoic to Modern evolutionary faunas. Herein, we propose first synthetic analysis diversity marine brackish-water ostracods over entire Triassic, light palaeoecological, palaeoenvironmental palaeogeographical contexts. Al...

Claraia Bittner, 1901 is a prominent extinct bivalve genus of the Permian-Triassic transition (Newell and Boyd, 1995). Although it first appeared in Wuchiapingian (Late Permian; Fang Zong-Jie, 2010), its massive proliferation immediate wake end-Permian mass extinction makes archetype cosmopolitan eurytopic disaster species hallmark base Triassic (e.g., Schubert Bottjer, Diener (1923, p. 38) fix...

The Mesozoic lacustrine revolution (MLR) represents a major evolutionary event in the continental realm (Cohen 2003 ). The decline in taxic diversity at the family level in lacustrine environments that took place during the late Paleozoic–Middle Triassic was reversed later in the Mesozoic, with diversifi cation seeming to have continued to the Quaternary, although potential biases may have affe...

We describe a new large predatory archosaur, Smok wawelski gen. et sp. nov., from the latest Triassic (latest Norian–early Rhaetian; approximately 205–200 Ma) of Lisowice (Lipie Śląskie clay−pit) in southern Poland. The length of the recon− structed skeleton is 5–6 m and that of the skull 50–60 cm, making S. wawelski larger than any other known predatory archosaur from the Late Triassic and Ear...
