This paper reviews identification of the auroch ( Bos primigenius) during the Holocene in Romania based on data from 190 archaeological sites, corresponding to Neolithic (including Chalcolithic), Bronze Age, Iron Age, Antiquity and the Middle Ages. The assemblages were analysed according to the geographical and historical regionalisation of the Romanian territory (i.e. Moldavia, Dobrudja, Wallachia, Banat, and Transylvania). The data reveal the rather low contribution of hunted aurochs to local economies, though with spatial and temporal variations. Although the species is currently extinct, aurochs still appear in the medieval samples from the 14–15th centuries, and the coincidence of the archaeozoological data with those from documentary sources is marked.

The paper presents the chemical composition and mineralogical distribution of the corrosion crust, more so the chemical composition and the texture of the metallic core on three silver coins dating from the seventeenth century, discovered in various tombs in the necropolis belonging to the former Stratenia Church from Iasi. These were examined by the corroboration of optical microscopy, electron microscopy coupled with X-ray diffraction (SEM-EDX) and the micro-FTIR techniques. The data allowed to establish the main alloy and of the evolutionary contexts during the laying period, based on the texture of the metallic core and on the layout of corrosion products.
