Changes to SAHRIS!

The South African Heritage Resources Information System (SAHRIS) has undergone a generational upgrade and restructure. These changes to the site include, but are not limited to:

  • A new & modernised look and layout
  • Improved site usage flows with respect to applications and content creation
  • Improved site performance and stability

Launch for the new version of SAHRIS occurred on Monday the 30th of October 2023.

ProposalDescription: 

The aim is to establish a comprehensive series of dates for the Drimolen fossil deposits (Keyser et al., 2000; Rovinsky et al., 2015; Adams et al., 2016). Provisional analysis of sediment samples sent to me in 2010 established the occurrence of magnetic reversals at the site. The aim is now to establish the complete nature of these magnetic reversals by more detailed sampling as well as combined electron spin resonance and cosmogenic burial dating.The site is in the Cradle of Humankind in Gauteng Province.

Expanded_Motivation: 

The aim is to undertake a comprehensive sampling of fossil teeth located within inset breccia for electron spin resonance analysis to be carried out by a PhD student in the Dept. of Archaeology at La Trobe University. Similarly, palaeomagnetic analysis will be conducted here by a PhD student. Cosmogenic burial dating on non-artifactual quartz will be conducted at the Australian Institute of Nuclear Science and Technology Organisation. The combination of these three methods along with uranium-lead dating of calcite will create a comprehensive series of ages for the various deposits and associated hominin (Paranthropus and early Homo) and other mammalian fossils. These methods have been shown to be effective at other sites but have rarely been used together as part of the same comprehensive study (Herries et al., 2009; Dirks et al., 2017).
