There were researched thousands of archaeological features, the defensive system of the site, the habitation neighborhoods and some other results of the human works (C 403 and C 1878 features) (romanian variante: Luca et al 2017). The archaeological feature C 403 is in area called C (plan 1) (Lazarovici et al 2014, Fig. 2; 28-30.). A part of this sector has been analyzed (ST29) some time ago in an ample article (Lazarovici et al 2014). In fact, in connection with this structure seems to be C 403 (Lazarovici et al 2014, p. 78, 79, 101-102). The feature is filled with black, granular soil (Lazarovici et al 2014, Fig. 28/b). This type of soil is formated, at Turdaș, during the Petrești inhabitation and we called him eneolithic humus (Luca 2001, p. 40). It is obvious that C 403 is – in fact – the rest of a dwelling, which is very poorly preserved and represents a higher deposition level, covering the ruins kept from the dwellings with floor of the upper level, Turdaș III (Lazarovici et al 2014, p. 86). The pottery of the dwelling is – obviously – Petrești (photo 1-2) (Lazarovici et al 2014, Fig. 28/a, c). Few preserved archaeological materials show a technique like in AB phase of culture, as defined by I. Paul (Paul 1992). C 1878 is a feature with a circular shape (column foundation) and is in sector B (plan 2, indicated by a blue arrow). She was partially covered by lateral debris of the C 340 (plan 2 was drawn after removing all the debris that was in secondary poistion; 1 Lucian Blaga University of Sibiu, Brukenthal National Museum Sibiu, sabinadrian.luca@ulbsibiu.ro, sabin.luca@brukenthal.ro 2 Laboratorul RoAMS, Institutul Naţional de Cercetare-Dezvoltare pentru Fizică şi Inginerie Nucleară „Horia Hulubei”, Măgurele-Ilfov 3 Muzeul Național Brukenthal, perianu.florentin@brukenthalmuseum.ro
