Abstract
The Pleistocene presence of the genus Homo in continental Southeast Asia is primarily evidenced by a sparse stone tool record and rare human remains. Here we report a Middle Pleistocene hominin specimen from Laos, with the discovery of a molar from the Tam Ngu Hao 2 (Cobra Cave) limestone cave in the Annamite Mountains. The age of the fossil-bearing breccia ranges between 164–131 kyr, based on the Bayesian modelling of luminescence dating of the sedimentary matrix from which it was recovered, U-series dating of an overlying flowstone, and U-series–ESR dating of associated faunal teeth. Analyses of the internal structure of the molar in tandem with palaeoproteomic analyses of the enamel indicate that the tooth derives from a young, likely female, Homo individual. The close morphological affinities with the Xiahe specimen from China indicate that they belong to the same taxon and that Tam Ngu Hao 2 most likely represents a Denisovan.

Funding Information:The team dedicates this work to Mr Thongsa Sayavongkhamdy. We thank the Ministry of Information, Culture and Tourism of Lao PDR for encouraging and supporting our work, marking almost 20 years of collaboration. We thank the authorities of Xon district, Hua Pan Province and the villagers of Long Gua Pa village for their continuous support of our numerous years of fieldwork. We also thank many curators and colleagues who granted access to the comparative fossil and recent hominin specimens for scanning, as well as the online sharing platforms of the Nespos society ( http://www.nespos.org ) and ESRF Paleontological database ( http://paleo.esrf.eu ). We acknowledge A. Mazurier and R. Macchiarelli (University of Poitiers), A. Bravin, C. Nemoz and P. Tafforeau (ESRF Synchrotron), P. Bayle and F. Santos (University of Bordeaux), O. Kullmer and F. Schrenk (Senckenberg Museum), F. Bernardini and C. Tuniz (ICTP Trieste), J. Braga and J. Dumoncel (University of Toulouse) for analytical support, microtomographic scanning and sharing of material. We gratefully acknowledge support from the CNRS/IN2P3 Computing Center (Lyon - France) for providing computing and data-processing resources needed for this work. Our thanks also go to Christine Lefèvre, Joséphine Lesur and Aurélie Verguin (Laboratoire Mammifères et Oiseaux, Anatomie comparée, MNHN, Paris) for access to comparative mammalian collections. Warm thanks to Jeremy Kazan (Taxidermie, MNHN, Paris) for having, as usual, wonderfully casted and reproduced the specimen. M.W.M. thanks George Morgan and Mark Keene at Adelaide Petrographics for expertly making the micromorphology thin sections.
