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.

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 ...

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 ...

Biostratigraphy of Triassic Ammonoids
2015The Triassic is a turning point in the evolutionary history of ammonoids, characterized by the flourishing Ceratitida and the appearance of the first heteromorphs. Following the end-Permian mass extinction, ammonoids were among the first groups to rediversify by producing many new taxa.

The Biostratigraphy of Permian Palynofloras
Proceedings of the Annual Meeting. American Association of Stratigraphic Palynologists, 1970Abstract Classical paleobotanical theory separates the floras of the Permian Period into four distinctive provinces: (1) the Gondwanian; (2) the Angaran; (3) the Ca‐thaysian; and (4) the Euramerican. These floras are based on the stem and leaf remains which are the chief preservable macroscopic parts of plants.

Geological Society of America Bulletin, 1983
The stratigraphic record is punctuated by episodes of mass extinction; these must be accounted for by major changes in the evolution of the Earth. Three groups of forces have acted on the Earth through time and may be adduced as the ultimate causes of many geological phenomena—including extinctions.

Microfossils and Geological Time gives a terrific review of the principles and development of dating rocks using the fossils that they contain (i.e. biostratigraphy). Although Brian McGoran concentrates on foraminifers, the book is worth reading for an understanding of the role of ...
