Wonderwerk Cave Project, South Africa 2013 – ongoing

Wonderwerk Cave currently has the oldest evidence for hominin use of cave sites in the world as well as evidence for use of fire by hominins c. 1 million years ago. Its archaeological layers span almost two million years, resulting in an unique archaeological and sedimentological repository in this arid region.

Michaela Ecker joined the project in 2013 as field director with the main responsibility of setting up of a digital survey system in the cave and database creation and management in addition to her doctorate work in stable isotope biogeochemistry at Wonderwerk. The Wonderwerk Cave research project is lead since 2004 by Michael Chazan (University of Toronto), Liora Horwitz (The Hebrew University Jerusalem) and includes c. 30 international researchers.

Modelling of climatic drivers in the summer rainfall zone of southern Africa during the Mid-Pleistocene 2016-2020

Together with Hiromitsu Sato (University of Toronto, Canada) and Douglas Kelley (Centre for Ecology and Hydrology, UK) we are exploring the possible drivers (Co2, rainfall seasonality, fire) leading to the signals we see in palaeoenvironmental records using climate models.

Ostrich eggshell: preservation, dating and environmental analyses

Ostrich eggshell is abundant in archaeological sites in southern Africa. It is easily recognisable and can be used for palaeoenvironmental analsyis as well as for dating by various methods.
