A model of the global biogeochemical cycles coupled to a energy-balance climate model
(the COMBINE model) is used to identify the causes of two large δ13C value excursions …

Conodonts, microfossils composed of carbonate-fluor apatite, are abundant in Palaeozoic–
Triassic sediments and have a high potential to preserve primary oxygen isotope signals. In …

The evolution of Earth's biota is intimately linked to the oxygenation of the oceans and
atmosphere. We use the isotopic composition and concentration of molybdenum (Mo) in …

This chapter is primarily concerned with the documentation of the record of land plants from
their earliest occurrences in the Ordovician to the end of the Lochkovian in the Lower …

Million year-scale (3rd-order) depositional sequences (few 10s to~ 100 m-thick) are
common in the Devonian marine record and are correlated between sedimentary basins …

The fossil record of wetlands documents unique and long-persistent floras and faunas with
wetland habitats spawning or at least preserving novel evolutionary characteristics and, at …

Among the most intriguing and significant aspects of the marine stratigraphic record are
patterns of temporal change in fossil assemblages and paleocommunities. Understanding …

The Lower Devonian plant-and arthropod-bearing cherts of the Rhynie area of
Aberdeenshire, NE Scotland, were deposited from silica-rich waters emanating from the hot …

A positive carbon isotope excursion is reported for the global Hangenberg Event near the
Devonian–Carboniferous boundary, one of the most significant Phanerozoic mass extinction …

A model (GEOCARB) of the long–term, or multimillion year, carbon cycle has been
constructed which includes quantitative treatment of (1) uptake of atmospheric CO2 by the …
