Fossil-based estimates of diversity and evolutionary dynamics mainly rely on the study of morphological variation. Unfortunately, organism remains are often altered by post-mortem taphonomic processes
* = pppaNegative estimates of variance components associated with non-significant F-ratios were assigned zero values in keeping with standard practice [26].bDenominator of the F-test is zero.
