Sedimentological and micropaleontological (conodont) analysis of the succession of the Middle Triassic (Ladinian) strata was performed. The succession is located by the road section Mišji Dol – Gradišče in the Sava Hills. The beds are deformed by folds and partially covered, so the section was divided into shorter parts, some of them were recorded in detail and other were only listed. Microfacial analysis was performed on 49 sedimentological thin sections. A total of 69 samples were taken for sedimentological and conodont analyses, each weighted approximately 1.5-2.5 kg. 12 microfacies were identified and described: radiolarian-fillament-peloid packstone; bioclastic-intraclastic grainstone; microbreccia, bio-litoclastic grainstone, in places packstone; mudstone; radiolarian-fillament wackestone-packstone; crystalline dolomite; dolomitized bioclastic-intraclastic-peloid grainstone with terrigenous component; calcilutite; tuff sandstone; quartz sandstone; bioclastic-intraclastic rudstone and silty supported sand breccia. In conodont assemblage occur species such as Budurovignathus gabrielae Kozur, Budurovignathus sp., Cratognathodus kochi (Huckriede), Gladigondolella malayensis Nogami, Gladigondolella tethydis Nogami, Gladigondolella sp., Neogondolella balkanica Budurov & Stefanov, Neogondolella cf. excentrica Budurov & Stefanov, Neogondolella constricta (Mosher & Clark), Neogondolella cornuta Budurov & Stefanov, Neogondolella sp., Paragondolella excelsa Mosher, Paragodnolella liebermani (Kovacs & Kozur), Paragondolella sp., Paragondolella sp. (cf. alpina) (Kozur & Mostler), Paragondolella trammeri (Kozur) and ramiform conodonts. Listed species place researched succession in the Upper Illyrian-Fassanian. Based on lithological composition of the sequence, sedimentation took place in a deep marine environment.
