Modern vertebrate track taphonomy at Lake Manyara, Tanzania

Studies modern tracks at Lake Manyara, to document the environmental and taphonomic controls on track preservation. This closed basin, saline lake closely resembles the depositional setting of many ancient track-bearing strata. It is shown that preburial track survivorship can be modelled as the interaction between three variables: 1) strain susceptibility of a substrate prior to track formation; 2) track loading stress; and 3) secondary reworking rate. -from Authors
