This paper introduces the excavations in several Paleolithic sites in the Khorramabad Valley, Western Iran. Apart from the two well-known sites of Ghamari Cave and Gar Arjene rock shelter, first excavated by Frank Hole and Kent Flannery in the 1960s, the Gilvaran and Kaldar caves were excavated for the first time. Here we present the stratigraphy of these sites, general data from the lithic assemblages, and the identifications of a small part of the faunal remains. Preliminary results are showing that all of the sites were occupied from the Middle and Upper Paleolithic onward, and therefore provide great potential for the study of the transition between these cultural periods. Our preliminary techno-typological observations show that the lower levels of the Gilvaran and Ghamari sequences may represent an early phase of the Middle Paleolithic.
