Discovery of a long-term refuge for ostracods (Crustacea) after the end-Permian extinction: a unique Carnian (Late Triassic) fauna from the Mersin Mélange, southern Turkey

Carnian (Late Triassic) ostracods from the Sorgun Ophiolitic Mélange (Southern Turkey): Taxonomy, palaeoenvironment, and evidence of predation

“…These new conclusions suggest a shallowing upward trend at the Tavusçayiri Block, which is reported for the first time here. The ostra-cod assemblage from the sample G11 also differs significantly from the older assemblage of the Tavusçayiri Block (Tetraporobrachia haeckeli radiolarian Zone assemblage; Forel et al, 2017) by the absence of deep-water and typical Palaeozoic taxa. This pattern might either be due to the final disappearance of deep-sea Palaeozoic taxa during this interval, marking the end of the transitional interval following the end-Permian extinction, or to the survival of such taxa only in deeper water.…”

“…The stars indicate the position of the ostracod-bearing sample studied here (Spongotortilispinus moixi radiolarian. Zone) and ostracod fauna from the Kilek section (Tetraporobrachia haeckeli radiolarian Zone; Forel et al, 2017). Ammonoid zonation after Gallet et al (1994) and Hornung et al (2007); conodont zonation after Mostler (1994, 1996) and Kozur (2003); radiolarian zonation after Kozur (2003), Moix et al (2007) and Dumitrica et al (2013).…”

“…Diversity patterns through space and time during this interval are pivotal to reconstruct the rate and mechanisms of biotic recovery and transition. In this discussion, ostracods, micro-crustaceans known from the Ordovician to present-day in all types of marine waters, recently provided challenging data which demonstrate the retention of primitive characteristics up to the Julian (Early Carnian), and thus reveal the protracted transitional interval following the end-Permian crisis in deep-waters (Forel et al, 2017). This stimulating discovery was made in the Mersin Ophiolitic Complex (MOC) in southern Turkey, which appears as a key area for the study of the Triassic biotic dynamics in marine environments.…”

Integrated Radiolaria, benthic foraminifera and conodont biochronology of the pelagic Permian blocks/tectonic slices and geochemistry of associated volcanic rocks from the Mersin Mélange, southern Turkey: Implications for the Permian evolution of the northern Neotethys

“…Previously, some researchers (e.g. Forel et al, in press; H. W. Kozur, Moix, & Ozsvart, , , , ; Moix et al, , ; Ozsvart, Dumitrica, Hungerbühler, & Moix, ; Ozsvart, Dumitrica, & Moix, ; Ozsvart, Moix, & Kozur, ; Tekin, Bedi, Okuyucu, Göncüoglu, & Sayit, ; Tekin, Bedi, Okuyucu, Göncüoglu, Sayit et al, ) have carried out detailed paleontological studies on blocks/tectonic slices in the Mersin Mélange to clarify the radiolarian, foraminiferal and ostracod assemblages. Among these studies, Moix et al () investigated the limestone and chert blocks within the Mersin Mélange and report a chert‐detrital limestone association (‘Karinkali Block’) near the Karincali‐Southwest section in this study (Figure ).…”
