Özet
The Guneyce Formation is well exposed in the Lake District of southwestern Turkey. It was deposited in the early Miocene in the Neotethys ocean and contains a large variety of trace fossils. The following ichnotaxa were recognized: Chondrites intricatus, C. targionii, ?Cosmorhaphe isp., Helminthopsis isp., Helminthorhaphe flexuosa, Lorenzinia isp., Naviculichnium marginatum, ?Nereites isp., Ophiomorpha rudis, ?Phycosiphon incertum, Planolites beverleyensis, cf. Rhizocorallium isp. and Thalassinoides suevicus. There is a lateral trend from proximal turbiditic successions to distal low-oxygen shaly mudstone. Ophiomorpha rudis ichnosubfacies, Paleodictyon ichnosubfacies of the Nereites ichnofacies and Zoophycos ichnofacies were identified.
