Distribution of δ13Ccarbon source and δ18O values for all taxa in the southeast Asian faunas (Supplementary Annexes S1, S3, S4) from Tam Hay Marklot48, Duoi U'Oi29, Nam Lot49, Tam Hang South29, Coc Muoi29, and Tam Ngu Hao (Cobra) Cave (this paper). All sites were found within a relatively narrow latitudinal belt between 23° and 20° running through the northern regions of Laos and Vietnam (Fig. 1). The sites follow a chronological order from left to right highlighting environmental changes through vegetation cover variation (δ13Ccarbon source) and likely rainfall regimes (δ18O). The outline of the violin plots represents kernel probability density, where the width shows the proportion of the data found there. The boxes from the box and whisker plots inside the violin represent the 25th–75th percentiles, with the median as a bold horizontal line
