 The Wonderkrater platinum spike is in marked contrast to the almost constant low Pt concentrations in adjacent levels.It is consistent with the Younger Dryas Impact Hypothesis and is the first of its kind in Africa, supplementing evidence for platinum anomalies at more than 25 other sites in the world.The platinum spike at the South African site has been interpreted in terms of global dispersal of platinum-rich dust at the time of the hypothesized asteroid impact, potentially associated with a crater of the kind found beneath the Hiawatha Glacier in Greenland.
