Abstract

By combining palaeobotanical and sedimentological data, several plant taphofacies are recognised and a taphofacies model envisaged, the most significant taphonomic constraint on palaeoecological studies being the stratinomic partitioning of vegetation prior to burial by fluvial hydraulic sorting. Plant material is restricted to channel elements with low preservational potential, therefore the extent of phytoterrestrialisation and soil productivity may have previously been underestimated. Indirect evidence for significant soil productivity, which may have increased chemical weathering, potentially altering atmospheric CO2 levels, is calculated from the stable carbon isotopic values of pedogenic carbonate nodules.
