A new paper from Aram Kosyan (other spelling Kossian) about the grooved ware in Ishuwa.
Grooved ware is a type of pottery that appears in many sites during the Early Iron Age, thus after 1200BC. Various theories have been proposed about it's origin. Migration from South Caucasus and northern parts of historic Armenia by Sevin and Burney. And local Elazig origin by Muller. Sevin linked it with Mushki tribes.
We don't have aDNA from Iron Age Elazig. But indirect evidence we have is rather supportive of migratory theory.
PS Notice there is an typographic error in the paper. In paragraphs discussing Kura-Araxian culture there should be EBA not EIA.
PPS Garducci use the term Nairi ware for this pottery
