LTKompleksą sudaro Sudotos akmens amžiaus gyvenvietė II (IP-2421/A), Sudotos senovės gyvenvietė-kaimavietė (AV–2301) ir Sudotos pilkapynas IV (IP–3004/A). Tyrimai vykdyti komplekso ŠR-R dalyje, geležinkelio sankasos V pusėje, ties Žeimenos ardomu skardžiu (XXb, XXI ir XXII plotai - apie 250 m²), taip pat geležinkelio sankasos R pusėje, ties pilkapio 8 liekanomis, kuris gerokai suardytas statant geležinkelį, mineralizuojant priešgaisrines linijas, tiesiant elektros liniją ir kelią bei klojant kabelius (70 m²). Taigi iš viso 2005 m. buvo ištirtas apie 320 m² dydžio plotas. Dalį tyrimų finansavo KVAD pagal „Apsaugos tikslais tiriamų archeologinių vietų programą" [p. 18].
ENThe Sudota archaeological complex consists of a Stone Age settlement, a barrow cemetery and a village site. In 2005 an area of about 320 m² was investigated. During the investigation cultural layers of three different archaeological objects were discovered: an up to 40 cm thick layer of a brownish-yellow sand represented the Stone Age settlement cultural layer; a 10 to 30 cm thick layer of a grey and bluish charred turf fill layer representing the basement of an eroded barrow and/or the cultural layer of an ancient village of the Late Middle Ages and remains of 3 barrows. 284 flint, 11 stone, 41 pottery and 2 iron artefacts were found. Besides that, about 20 tiny charred bones were collected; most of them must have originated from the burials of the eroded barrows and dated to the 4th-5th century. The flint and other stone artefacts dated from the Late Palaeolithic to the early Bronze Age and were attributable to the Swiderian, Kunda and Narva cultures, whereas the hand-made pottery dated to the Neolithic Period and the Middle Iron Age. The wheelmade pottery was attributable to the village of the 18th - mid 19th century.
