In Sepember 2002 staff members from the Iron Age Department of the State Archaeological Museum Warsaw carried out sondage excavation of site 6 at Przeradowo, comm. Szelków, distr. Maków Maz., woj. mazowieckie. The site lies on the flood terrace of river Orzyc, right-hand tributary of the Narew river, some 100–200 m west of the river, about 200–300 m north-east of the village. Excavation identified the remains of a Przeworsk culture cemetery and settlement from the close of the Late PreRoman and Early Roman Period. There was also some Wielbark culture material, dated to phases B2/C1–D. Of special interest is chronologically the latest find from the site, ie a bronze beak-shaped strap end (Fig. 1). To date, 38 similar specimens known from 33 sites (Fig. 2) used to be treated as forms diagnostic for the later stage of phase D. However, there is evidence to suggest that the dating of the strap end form in question may be extended to phases C3 and D. The earliest beak-shaped specimen is known from the Wielbark culture area (Stary Targ, grave 241). The fact that the same area registers the greatest stylistic diversity of these forms (cf fig. 3:2.9.15.20. 27.28) suggests that beak-shaped strap ends may have emerged and developed in the Wielbark culture environment.
