Tauţ (Miocene of Romania)

Also known as Taut, Migieşului Valley, Migiesului

Where: Arad, Romania (46.3° N, 21.9° E: paleocoordinates 45.8° N, 21.6° E)

• coordinate based on nearby landmark

When: Sarmatian (12.7 - 11.6 Ma)

• "[...] Volhynian substage of the Sarmatian, which may correspond to the lower part of the Sarmatian (late middle Miocene) (Grigorescu & Kazár 2006). Based on micromammals, Feru et al. (1980) assigned the Tauţ locality to the MN 8 of the European Neogene Mammal zones system (Mein 1975)."

Environment/lithology: lacustrine; unlithified, tuffaceous, green claystone

• "[...] the outcrop of narrow extent consists from tufaceous green clays enclosing rare shells of Planorbis Müller, 1774 and Helix Linnaeus, 1758."

Size classes: macrofossils, mesofossils

Collected by M. Feru, C. Rădulescu, P. Samson in 1979

• "During a survey on the microvertebrate fossils from the collections of the Speleological Institute 'Emil Racoviţă' (ISER), Bucharest, we found a huge amount of herpetological material from Tauţ, collected by M. Feru, C. Rădulescu and P. Samson in 1979. The material has never been mentioned in any papers of the above authors."
