A large assemblage of charred cereal grains was found at the multicultural site Kraków Nowa Huta Mogiła 62 during a rescue excavations performed in the late 1960s. It provided valuable source of material for archaeobotanical and stable isotope studies. Both current botanical analyses of six subsamples and new radiocarbon dates of the top and the bottom of the layer indicated their Middle Neolithic origin (the Funnel Beaker culture). Despite the earlier suspicion that the material was disturbed by the construction work, the field documentation stored in the Archaeological Museum and the new archaeobotanical analyses indicate that the layer with the cereal grains, which was found at the depth of 300–330 cm was in fact, undisturbed. The cereals (mostly emmer with admixture of einkorn) were stored in a form of spikelets (as indicated by proportions of chaff and grains) and the assemblage was a final product of harvest cleaning (as suggested by low number of arable weeds). Values of stable carbon and nitrogen ratios suggest that the storage contained cereals originated from plots of different level of manuring and similar soil moisture, however more isotopic measurements are necessary to confirm that hypothesis. It is also supported by different proportions of taxa in the studied subsamples. Most of the emmer grains were sprouted before charring. We assume the grain was spoilt by excessive humidity of the storage conditions.

Radiocarbon dating of the plant material is important for chronology of archaeological sites. Therefore, a selection of suitable plant samples is an important task. The contribution emphasizes the necessity of taxonomical identification prior to radiocarbon dating as a crucial element of such selection. The benefits and weaknesses of dating of taxonomically undetermined and identified samples will be analysed based on several case studies referring to Neolithic sites from Hungary, Slovakia and Poland. These examples better illustrate the significance of the taxonomical identification since plant materials of the Neolithic age include only a limited number of cultivated species (e.g. hulled wheats) and typically do not contain remains of late arrived plants (e.g. Carpinus betulus and Fagus sylvatica). For more accurate dating results cereal grains, fruits and seeds, which reflect a single vegetative season, are preferred. Among charred wood, fragments of twigs, branches and external rings should mainly be taken into account, while those of trunks belonging to long-lived trees should be avoided. Besides the absolute chronology of archaeological features and artefacts, radiocarbon dating of identified plant remains might significantly contribute to the history of local vegetation and food production systems.

Badania paleobotaniczne na stanowiskach archeologicznych położonych w obrębie dzisiejszego Krakowa rozpoczęto w latach 30. XX wieku, ale ich intensywny rozwój nastąpił po II wojnie światowej. W badaniach tych wyróżniono dwa etapy. W starszym (do 1965 r.) najbogatsze materiały roślinne pozyskano ze wzgórza wawelskiego i z Rynku Głównego. Badania etapu młodszego (rozpoczęte po 2000 r.) związane były z najnowszymi pracami archeologicznymi prowadzonymi m.in. na Rynku Głównym, przy ul. Kanoniczej 17, Krupniczej 7 i w kilku innych punktach Starego Miasta. Najwięcej informacji o dawnej roślinności dostarczyły analizy nawarstwień średniowiecznych. W wielu przypadkach udało się wykazać zmiany intensywności i sposobu użytkowania badanych powierzchni i obiektów. Zarejestrowano duże zróżnicowanie przestrzenne i chronologiczne rozmieszczenia szczątków roślinnych w osadach.

Palaeobotanical studies of archaeological sites situated on the territory of modern Kraków were initiated in the thirties of the 20th century but intensive explorations began after the World War II. The investigations can be divided in two periods. The older one was based on materials collected from archaeological excavations carried out from the late forties to ca. 1965. At that time the richest plant remains were obtained from the Wawel Hill and the Main Market Square (Rynek Główny). The studies of the younger period, which began after 2000, are connected with the new archaeological works carried out in the Main Market Square, at Kanonicza 17 St., Krupnicza 7 St. and in several other places of the Old Town. Most of the data were obtained from the Medieval layers. In a few cases it was possible to indicate changes in the intensity and ways of management of the studied features. Considerable spatial and chronological variation of the distribution of plant remains was observed.
