Abstract
Chitinozoans bracket the geological age of the Soom Shale at the base of the Cedarberg Formation of South Africa as Lower Silurian to Upper Ordovician whereby the oldest age is the more probable.
On account of the organic cemetamorphism the most likely maximum depth of burial of the Soom Shale was slightly in excess of 5000 meters.
