Fishing history of the East Baltic during the Holocene according to underwater multiperiod riverine site Kaltanėnai, northeastern Lithuania

Abstract

In 2015, professional diver and amateur archaeologist A. Matiukas discovered an extraordinarily rich and well-preserved underwater multiperiod archaeological site, Kaltanėnai, at the point where the Žeimenys Lake feeds into the Žeimena River in East Lithuania. Over the duration of 3 years of multiple diving expeditions, he collected ca. 800 archaeological finds made of wood, bone, antler, flint, stone, iron and glass. Moreover, in eroded places of the river bed, he observed numerous wooden piles of potential constructions. These initial finds attested the newly discovered site’s great scientific value and potential, and therefore a scientific investigation of the site was initiated. This paper presents the first results of underwater survey at this site and analyses of its various finds. These include the site’s plan with a mapping of stationary fishing gear, a geological profile made from boreholes, 23 14C dates of various artefacts and wooden constructions, wood and animal taxa determinations including ZooMS, and traceological analysis of osseous tools. Our research demonstrates that the site was intensively used for fishing via various methods starting from the Late Mesolithic to the modern era, while most of the finds date to the Subneolithic and the Bronze Age. Further research at the site, including underwater excavations of stratified archaeological layers, will shed even more light onto the history of inland fishing in the East Baltic.
