Prapovijesni arheološki lokalitet Kaptol za sada je najznačajnije željeznodobno nalazište na području sjeverne Hrvatske te je i epomnimni lokalitet istoimene najjužnije skupine halštatskoga kulturnog kompleksa. Nekropola na položaju Čemernica istraživana je od 1965. do 1971. godine, kada je istraženo 14 tumula. Nakon toga u tri su navrata provedena kompleksna revizijska istraživanja: 2007. godine bio je istražen tumul XI – najsjeverniji tumul na nekropoli Čemernica, nakon dvije godine tumul III, te 2016. tumul IV. U ovome radu po prvi puta prezentiramo rezultate arheobotaničkih istraživanja halštatskih tumula III i XI na položaju Kaptol – Čemernica. Flotirane su ukupno 674 litre sedimenta iz tumula III i XI te izdvojeno ukupno 16285 karboniziranih biljnih ostataka. U oba tumula apsolutno su najbrojniji nalazi žitarica (preko 90%). Zbog loše očuvanosti materijala, polovica nalaza žitarica determinirana je kao Cerealia (krupnozrne žitarice), među bolje očuvanim nalazima u oba tumula prevladava pšenica (Triticum), a od izdvojenih tipova pšenica najbrojnija je obična ili krušna pšenica (Triticum aestivum). S obzirom na veliku količinu nalaza, prije svega žitarica, može se zaključiti kako je biljna komponenta grobnih rituala u starijem željeznom dobu imala puno veći značaj nego što se to do sada mislilo. The prehistoric archaeological site of Kaptol is the most significant Iron Age site in northern Croatia discovered to date. It has given its name to the southernmost group within the Hallstatt cultural complex. The necropolis at the location of Čemernica was excavated between 1965 and 1971, with 14 tumuli encompassed by the archaeological investigation. Thereafter, three rounds of complex revision excavations were conducted: in 2007, tumulus XI – the northernmost tumulus in the Čemernica necropolis – was excavated; two years later, tumulus III; and, in 2016, tumulus IV. This is the first presentation of the results of archaeobotanical research of Hallstatt tumuli III and XI at the Kaptol – Čemernica site. In total, 674 litres of sediment from tumuli III and XI were floated, resulting in the recovery of 16.285 carbonized plant remains. The overwhelming majority (more than 90%) of finds from both tumuli are those of cereals. Due to the poor preservation of the plant material, half of the cereals have been identified as Cerealia (large-grained cereals). Wheat (Triticum) is predominant among the better-preserved remains from both tumuli, with common wheat (Triticum aestivum) being the most numerous among the types of wheat identified. In view of the large quantity of plant remains, predominantly cereals, the conclusion can be drawn that the plant component of the Early Iron Age burial ritual was much more important than we thought.
