Taxonomic study of the tetrahedral, pentagonal and hexagonal spongy spumellarian Radiolaria from the middle Carnian (Late Triassic) of the Köseyahya nappe (Elbistan, SE Turkey) and other Triassic localities

Mono- and dicyrtid Nassellaria (Radiolaria) from the Upper Carnian of the Sorgun Ophiolitic Mélange, Southern Turkey and Kopría Mélange, Rhodes, Greece

“…These similarities prove doubtlessly that both faunas come from the same paleogeographic area. These two faunas have many elements in common with the upper Carnian (Tetraporobrachia haeckeli Zone) fauna from the Köseyahya Nappe in Elbistan (Tekin and Bedi, 2007a, b, Dumitrica et al, 2010, 2013a. In this paper, we continue the taxonomic work of the exceptionally preserved lower Tuvalian radiolarians by the description of several new taxa of Nassellaria from the Sorgun Ophiolitic Mélange and from the Kopría Mélange, Rhodes (Greece).…”

“…4). An equivalent but not so rich radiolarian fauna has been partly described by Dumitrica et al (2010Dumitrica et al ( , 2013a and Dumitrica and Hungerbühler (2007) from cherts of the Zulla Formation, Hawasina Complex, Oman.…”

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

“…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). 6 The illustrated specimens and types are deposited in the collections of the Hungarian Natural History Museum, Budapest, under the numbers INV 2018.1 to INV 2018.31.…”

Middle-Late Triassic radiolarian cherts from the Arkotdağ mélange in northern Turkey: implications for the life span of the northern Neotethyan branch

“…In the Pelitören section, the sample (12-TC-303A) taken from the basal part of the section yielded Spongotortilispinus tortilis ( Figure 6), some of them (P. nazarovi, Nodotetrasphaera cive and Annulotri-assocampe sulovensis) disappear close to the end of middle Carnian based on the recent studies in SE Turkey (Dumitrica, Tekin, & Bedi, 2010, 2013a, 2013bTekin & Bedi, 2007a. Three taxa (Canoptum cucurbita, C. inornatum and C. levis) are crucial to determine the upper limit of the age of the sample ( Figure 6).…”
