Extinction Selectivity

Three Timer Sampling Completeness of the Marine Invertebrate Fossil Record (calculated using equations from Alroy, J. (2008). Dynamics of origination and extinction in the marine fossil record. Proceedings of the National Academy of Sciences105(Supplement 1), 11536-11542.)

Extinction Selectivity

Extinction selectivity studies use ecological and physiological traits to analyze patterns of extinction during background and mass extinction intervals. Such studies require occurrence data in time and space of fossils. For my first year MSc project, I am attempting to quantify uncertainties in the first and last appearances dates of taxa (FADs and LADs) as a result of the Signor-Lipps Effect. I hope to re-assess extinction selectivity measures on marine invertebrates by integrating temporal sampling completeness, taxon specific sampling completeness, and size biases, through capture-mark-recapture methods.
