| Summary: | This study aims to determine the age of prehistoric pottery from Karaga Bay coast, northern Kamchatka, Russia. From a typological viewpoint, pottery in this region is divided into four types:Ivashka type, Kavran type, pottery with clay rope ornamentation, and pottery covered by a square/rectangular-shaped impression. The ceramic set is classified into two patterns:a composition solely consisting of Kavran type (“composition-I”) and a composition consisting of various types as well as Kavran type (“composition-II”). According to AMS (acceleratormass spectrometry) radiocarbon dating,thetypological features ofKavran typewere largelyunaltered from the11th to the17th centuryCE. However,ceramiccomposition can bean effectiveindicatorofage;“composition-I”isdated to theolderstagebetween the11th and the13th centuryCE, and “composition-II”can be assigned to the newer stage during the second halfof the15th to thefirst halfofthe17th centuryCE. This chronological schemesuggests that cultural interaction in the newer stage between Karaga Baycoast and adjacent areas is more active than in the older stage.
