The local paleoenvironment of Kalavan‐2 based on small‐vertebrate remains and its implications for human‐environment‐dynamics between 60 and 35 ka in the Armenian Highlands

open access: yesJournal of Quaternary Science, Volume 41, Issue 1, Page 153-177, January 2026.
ABSTRACT Kalavan‐2, a high‐altitude (∼1640 m a.s.l.) open‐air site in Armenia, preserves stratified Middle Paleolithic occupations with a rich small‐vertebrate record. Luminescence dating has placed site formation between ~60 and 45 ka, but without independent chronological control of the microvertebrate accumulation.
