Abstract

Thelodont scales are described from the Silurian Niur Formation in the Derenjal

Silurian stratigraphy of Central Iran – an update

“…In recent years, significant progress has been made in the study of the Silurian sedimentary sequences of the Zagros Basin and Central Iran (Tabas and Kashmar regions) where abundant graptolites, ostracodes, rugose corals, palynomorphs (including acritarchs and chitinozoans) and sporadic fish remains were documented in a number of recent publications (for summary see Ghavidel-Syooki 2001;Hairapetian et al 2008Hairapetian et al , 2011. The Silurian brachiopods and conodonts of Central Iran are currently under extensive study and are partly published (Hairapetian et al 2012;Männik et al 2013Männik et al , 2015Popov and Cocks 2013;Popov et al 2015a).…”

“…The best section in the area is situated c. 1.4 km east of the DahanehKalut valley and 8.3 km north-north-east from the Shirgesht railway station. The profile is composed of outcrops located across three major hills named A, B and C by Hairapetian et al (2008).…”

“…For a long time the rugose and tabulate corals, and stromatoporoids described by Flügel (1969), Flügel and Saleh (1970) and Hubmann (1991) were the only Silurian fossils monographically documented from the area. Recently, rich Silurian faunas, including brachiopods, ostracodes and thelodont fishes, have been discovered and published by Hairapetian et al (2008Hairapetian et al ( , 2011Hairapetian et al ( , 2012) from the section. The distribution of Llandovery to Ludlow conodonts (Männik et al 2013) indicates that the Derenjal Mountains show the most complete Silurian sedimentary succession so far documented in Iran.…”

“…1; see also Ruttner et al 1968;Hairapetian et al 2008). The Silurian deposits crop out relatively widely in the southern and eastern parts of the Derenjal Mountains, on the flanks of a large anticline.…”

Endemic thelodonts (Vertebrata: Thelodonti) from the Lower Silurian of central Asia and southern Siberia

“…However, the name Loganellia was first published by Fredholm (1990, p. 69), who inadvertently cited the article of Turner, which was in press at that time (published as Turner 1991). Therefore, the correct name should be ''Loganellia Fredholm, 1990'' (see Märss et al 2007, p. 49;Hairapetian et al 2008).…”
