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.

PAST PROJECTS

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.

Results: Ecker, M., Kelley, D. & Sato, H. Modelling the effects of CO2 on C3 and C4 grass competition during the mid-Pleistocene transition in South Africa. Sci Rep 10, 16234 (2020). https://www.nature.com/articles/s41598-020-72614-2

Excavations at Pniel, lower Vaal River, South Africa 2017-2019

Principal Investigators: Michaela Ecker & David Morris.

Funded by the Quaternary Research Association (QRA) Quaternary Research Fund; Rust Family Foundation & The Palaeontological Scientific Trust (PAST), Johannesburg, South Africa.

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.
