The Ordovician System: From overlapping unit stratotypes to Global Boundary Stratotype Sections and Points [PDF]
For nearly a century the Ordovician System was hidden as Murchison and Sedgwick tussled over the overlapping ground between their Silurian and Cambrian systems.

Paleoceanography and dinoflagellate cyst stratigraphy across the Lower–Middle Pleistocene Subseries (Calabrian–Chibanian Stage) boundary at the Chiba composite section, Japan [PDF]
A dinoflagellate cyst record from the highly resolved Chiba composite section in Japan has been used to reconstruct sea-surface paleoceanographic changes across the Lower–Middle Pleistocene Subseries (Calabrian–Chibanian Stage) boundary at the global ...

In search of the Palaeogene-Neogene Boundary Stratotype
In publishing the first results of its research works (Giornale di Geologia, vol. XLIV, fasc. l-Il, 1981 ) the Palaeogene/Neogene Boundary Working Group, while not having defined any final object yet, has nonetheless enabled us to: a) recall attention to

Ice-volume-forced erosion of the Chinese Loess Plateau global Quaternary stratotype site [PDF]
A basic requirement for reconstructing past environmental change is accurate understanding of sediment age. Here, the authors show that the interpretation of a benchmark archive in China has been inaccurate, and that ice volume primarily controls desert ...

The Aptian Marls of La Tuilière (Luberon UNESCO Global Geopark, France), a Historical Stratotype [PDF]
The historical stratotype of the Aptian Stage (Cretaceous) was defined in the Luberon UNESCO global geopark in the middle of the 19th century. Due to excessive urbanization launched in the early sixties, the best outcropping conditions are those found at

A short history of the Ordovician System: from overlapping unit stratotypes to global stratotype sections and points [PDF]
Abstract The Ordovician System was introduced by Charles Lapworth as a solution to the overlapping unit stratotypes loosely defined by Adam Sedgwick, for the Cambrian, and Roderick Murchison, for the Silurian. The Ordovician has emerged as one of the longest and most significant of the geological periods.
