Niespolo et al. (1) report 230Th/238U “burial ages” for ostrich eggshell fragments from a 3.8-m-thick Middle Stone Age (MSA) sequence at Ysterfontein 1 shelter, west coast of South Africa (2). The ages are in expected stratigraphic order and imply that the entire 3.8-m sequence accumulated in as little as 2,300 y around 115,000 y ago. The authors believe they have identified the oldest firmly dated evidence for systematic human exploitation of coastal resources and that the remarkably rapid rate of deposition means that local MSA people were exploiting coastal resources as intensively as …
