 Archaeologists Eszter Istvánovits and Valéria Kulcsár write that no archaeological evidence substantiates the Gepids' presence before around 350.Graves from the which yielded swords, lances and shields with iron boss were unearthed in cemeteries between the rivers Tisza and Körös (in present-day north-eastern Hungary and north-western Romania).Many scholars (including Kurdt Horedt, István Bóna and Coriolan H. Opreanu) attribute those graves to Gepid warriors.
