Interpreting MSA sequences from open-air sites is challenging in tropical environments. We advocate using sedimentology, micromorphology, OSL and phytolith analyses to analyze site taphonomy. Lake proxy data, phytoliths and micromorphology show variable mildly xeric to pluvial ecosystems. Chaminade-II has MSA activity from >47 to >17ka on a slowly aggraded, partially eroded alluvial fan. Post-depositional effects must be considered to accurately reconstruct site histories.
