According to studies, about 65 million years ago, the Earth experienced a major global extinction event that marks the boundary between the Mesozoic and Cenozoic eras and on a finer scale, the Cretaceous and the
Palaeogene.
The
Palaeogene strata of the SFTB represent shallow marine carbonates, shallow and deep marine clastics, providing remarkable opportunities for accurate biostratigraphic correlation (Dungan Formation, Ghazij Formation, Kirthar Formation) (Warraich and Natori, 1997; Warraich and Nishi, 2003; Afzal et al., 2009; Ali et al., 2018).

Cycad genera either diversified in the
Palaeogene (66-23 MYA), and had two diversification rate shifts, or during the Neogene (23-2.6 MYA), with four rate shifts accounting for each of the four richest genera: Cyacas, Zamia, Encephalartos and Macrozamia (Condamine et al., 2015).
Prior to the Quaternary two periods are thought to have been particularly important for the development of karst features (Bosak et al., 1993): extensive depressions and underground drainage systems originated during the early Cretaceous (Bosak et al., 1989) while intensive karstification and weathering occurred during the late Cretaceous and
Palaeogene (Bosak, 1990).
The catchment is mostly composed of limestones from the Cretaceous and
Palaeogene era with some dolomitic parts.

palaeogene excreta.
The Niger Delta has three major depositional prisms: (1) a Cretaceous deltaic complex developed 600 miles inland from the mouth of the Niger Delta, (2) a Late Cretaceous to
Palaeogene "proto Niger" delta complex formed seawards of the earlier delta, and (3) the younger Cenozoic complex built out over newly formed oceanic crust as the South Atlantic opened during the separation of the South American and African tectonic plates.

Palaeogene of the Paris Basin, France.
Among the topics are projected future climate changes in the context of geological and geomorphological hazards, evidence from Sicily's Mount Etna for climate change and collapsing volcanoes, multiple effects of ice load changes and associated stress change on magmatic systems, whether El Nino--southern oscillation influences earthquake activity in the eastern tropical Pacific, high-mountain slope failures and recent and future warm extreme events, and a view from the
Palaeogene on methane hydrate instability.
