What if linguistic anthropological studies of sensory evaluation began not with wine connoisseurship but with scat identification? Focusing on Sino-Tibetan community-science collaborations on the Tibetan Plateau, this paper examines wildlife scat—a crucial indicator for Indigenous experts and conservation biologists. In everyday life, Tibetans and Han Chinese rarely agree on shit; yet, collaborative scat identification sustains a scientific chronotope that suspends macro-level ethnonational frictions. Analyzing an English-language scatological manual alongside a Mandarin-Amdo Tibetan interactional transcript, I investigate the specialized linguistic repertoire used to calibrate scat observation. By examining how speakers simultaneously describe perception (“sensation”) and judge species origin (“ontology”), I argue that adjectival predicates function as dynamic interactional operators—a phenomenon I term adjectival deixis. Ultimately, this paper delineates two core functions of adjectival deixis: chronotope projection and referent configuration. In doing so, it reveals how referential practice drives intersubjective sensory calibration and rapport-making, co-constituting language-use and materiality.
