LT2012 m. gegužės mėnesį vykdyti Kapitoniškių pilkapių vietos (UK 25174) (Kaišiadorių r., Rumšiškių sen.) žvalgomieji tyrimai. Kapitoniškių pilkapių vieta yra dešiniajame Kauno marių krante. Tai dalis archeologinių paminklų, išsidėsčiusių tarp Dovainonių ir Kapitoniškių, komplekso. Šiuo metu jį sudaro Dovainonių (Kapitoniškių) pilkapynai I–V, Dovainonių (Kapitoniškių) piliakalnis ir Kapitoniškių pilkapių vieta. Šiuos saugomus archeologinius paminklus jungia bendras vizualinis apsaugos zonos pozonis. Be to, apie 100 m į PV nuo Kapitoniškių pilkapių vietos yra į KVR neįtraukta Kapitoniškių palivarko vieta. Praeityje netoli būta ir daugiau paminklų: apie 1–1,1 į Š nuo Dovainonių (Kapitoniškių) pilkapynų buvo pilkapynas, anksčiau vadintas Dovainonių pilkapynu II. Dabar čia pilkapių jau nėra išlikę. Į R nuo Kapitoniškių pilkapių vietos, dabar Kauno marių bent dalinai užlietoje teritorijoje buvo Kapitoniškių pilkapynas. Be to, įvairiose vietose praktiškai visame aptariamame mikroregione aptikta akmens–geležies amžiaus radinių: titnaginių dirbinių ir titnago nuoskalų, akmeninių kirvių, brūkšniuotosios bei grublėtosios keramikos šukių, geležies šlako ir gargažių ir kt. Radimviečių teritorijos nėra nustatytos, jos neįtrauktos į NKVR, daugelis šių radinių aptikta tyrinėjant kitus paminklus. [...] [p. 86-87].
ENIn 2012, an evaluation was conducted at the Kapitoniškės barrow site (Rumšiškės eldership, Kaišiadorys district). This site is part of an archaeological complex situated between Dovainonys and Kapitoniškės villages. On the 3280 m2 plot, seven 10–66 m2 trenches and one 4 m2 test pit (a total of 164 m2) were excavated. A geophysical survey using georadar was conducted and five 5 GPR profiles were made. Trench 1 (6x3 m) contained a bronze brooch or decoration, probably from the 19th–20th centuries, trench 2 (6x3 m) a potsherdwith a rough surface, and trench 3 (6x2 m) a partially melted fragment of a bronze twisted wire neck-ring, that dates to the late iron age and probably found its way there from a destroyed burial; several nails; a horseshoe nail, part of a bit fastener, and part of a knife tang. In trench 3 two grey clay loam stains and the contour of black charcoally soil (the remains of a pyre site of unclear chronology) were found. The only find in trench 4 (10x2 m) was a sherd from a hand thrown, brown glazed vessel. No finds were discovered in trench 5 (9x2 m). Trench 6 (22x3 m) yielded the best results. A 5–18 cm thick layer of yellowish grey sand, which contained burnt bones, split and unsplit stones, and flint finds (a stone age cultural layer), was unearthed at a depth of 42–50 cm in its SW part. In it was found an irregularly shaped contour that was 2–3 m in diameter, 10–12 cm deep, oriented E–W, and filled with greyish sand with sparse quantities of small pieces of charcoal-the remains of a sunken building (?) (object 4). Flint flakes and fragments of small burnt bones were discovered in it. Based on a flake from a ground flint axe, object 4 can be dated to the late neolithic.At a depth of 40–50 cm in the middle of trench 6 was the roughly 3.5x1.5 m oval contour of a stain of grey charcoally sand: object 1. It was set 10–25 cm into sterile soil. The stain contained burnt split stones, charcoal, and 41 finds (sherds of pottery with rough surfaces, a flake from a stone axe or hoe, pieces of daub, flint flakes, and small fragments of animal bones). Another contour of grey charcoally sand (object 2) was unearthed beside object 1 at a depth of 40–50 cm. It was an irregular strip about 1.65 m long and 30–60 cm wide. The object was set 10–22 cm into sterile soil. It contained burnt and split stones, charcoal, and 18 sherds of pottery with rough surfaces and a burnt flint flake. Object 3 was a stain of light grey sand with small pieces of charcoal that was uncovered after excavating through object 1 down to a depth of 56 cm. The stain was 60x58 cm in diameter and set 22 cm into sterile soil. Fragments of burnt animal bones and a potsherd with a rough surface were found in the object. Samples were taken from this object for radiocarbon dating. Unfortunately the obtained date: Vs 2270: 3910±340 BP (σ1 2880–1970 cal BC) must be deemed unreliable. Objects 1–3 can be considered mid 1st millennium pyre sites. A fragment of a horse mandible that perhaps found its way there from a destroyed horse burial was found in trench 7 (5x2 m). A band of grey gravelly sand, a former stream bed, was recorded in 2x2 m test pit 1. The only find in it was a retouched flint flake. Six new find spots, where 38 flint and pottery finds dating to the mesolithic-modern age were collected on the ground’s surface, were discovered on the grounds of the Kapitoniškės barrow site and in its vicinity.
