In 2020, the construction of a pipeline led to a rescue archaeological excavation at the 130–240 cal AD Roman Iron Age settlement site near Skudeniai. The discovered material from its brief occupation has provided substantial new data on unenclosed settlements in the Late Striated Ware Culture. The distinct posthole accumulations in the surveyed area make it possible to identify building locations and to analyse the settlement’s structure by differentiating between the domestic and economic activity zones. The collection of pottery from Skudeniai’s brief existence provided a better understanding of the differences between the contemporary pottery groups. The first ever application of the petrographic method in the analysis of this culture’s ceramics also yielded important results that led to a new classification system that established distinctions between the three contemporary pottery groups. The archaeobotanical material from Skudeniai is of great importance for understanding the development of agriculture as it is only the second Late Striated Ware Culture archaeobotanical assemblege from a chronologically pure context. The article also analyses issues related to non-ferrous and ferrous metallurgy and trade connections.
