North Bačka is rich in Avar-age discovery places. The larger discovered settlements' anthropological procession has been made in the most of the cases (Czekus 1985, Cekuš, 1991a, 1991b; Czekus, 1990, 1995, Farkas, 1984). In our work we analyzed the skeletons found in the Avar-age cemetery in Martonos. There were 8 of the grown ups' skeleton which's skull (cranium) (at least in parts) and the longer bones (postcranium) were found, and three of them had only the latter, while only a few longer bone remained of the child-skeletons. Only two of them lived until his old age. Both the skull and the long bones' size are heterogeneous. Their height is average and tall. The epigenetic properties refer to sexual dimorphism.
