Ichnological and archaeological evidence from Gombore II OAM, Melka Kunture, Ethiopia: An integrated approach to reconstruct local environments and biological presences between 1.2 and 0.85 Ma

Abstract

New ichnological data are available at the prehistoric site of Melka Kunture, Upper Awash Valley in Ethiopia. Excavation of new test pits enabled us to explore the volcanic and fluvio-lacustrine sequence at the Gombore II Open Air Museum archaeological site (ca. 0.85 Ma). This has allowed a detailed reconstruction of the palaeoenvironment and of the fauna present in the time interval between 1.2 and 0.85 Ma. Various-sized mammals, birds, molluscs as well as hominins left tracks throughout the sequence, and document a varied fauna and associated behaviours. Most of the hominin tracks were made by young individuals on the basis of size and are some of the earlier child tracks to be reported. The mollusc traces document the presence and orientation of water streams which, according to the associated vertebrate traces, were visited by hominins, mammals and birds. Most of these traces were found within levels traditionally considered barren for archaeology, yet they all document life activity and are always in situ. This confirms the potential of the ichnological research as an important complementary tool for archaeological investigations.
