Using fossils to tell geological time, biostratigraphy balances biology with geology. In modern geochronology - meaning timescale-building and making correlations between oceans, continents and hemispheres - the microfossil record of speciations and extinctions is integrated with numerical dates from radioactive decay, geomagnetic reversals through ...

Systematic biostratigraphy: A solution to problematic classification systems in biostratigraphy
Palaeoworld, 2014Abstract Systematic biostratigraphy is based on the exclusive use of monophyletic marker taxa. Non-monophyletic, or artificial, marker taxa have been shown to change biostratigraphic correlations, a situation that can be rectified by using systematics to ensure that marker taxa are monophyletic or natural.

Micropaleontology and Biostratigraphy
2021To stratify six sediment cores, we applied the calcareous plankton biostratigraphy of the upper sediment cover based on the foraminiferal and nannofossil zonations suggested in Chap. 3 for the Ioffe Drift area. Datum levels (first and last appearances) of zonal index species in individual cores were used to denote zonal boundaries. The oldest recovered

Paleozoic Ammonoid Biostratigraphy
2015Introduction: The research field of Paleozoic ammonoid biostratigraphy has undergone major changes in the last few decades. In early attempts at ammonoid biostratigraphy in the 1980s, research efforts mainly focused on the stratigraphical subdivision of the rock succession and the correlation of time equivalent assemblages with the aim of a uniform ...
