The term Anthropocene, proposed and increasingly employed to denote the current interval of anthropogenic global environmental change, may be discussed on stratigraphic grounds. A case can be made for its consideration as a formal epoch in that, since the start of the Industrial Revolution, Earth has endured changes sufficient to leave a global stratigraphic signature distinct from that of the Holocene or of previous Pleistocene interglacial phases, encompassing novel biotic, sedimentary, and geochemical change. These changes, although likely only in their initial phases, are sufficiently distinct and robustly established for suggestions of a Holocene–Anthropocene boundary in the recent historical past to be geologically reasonable. The boundary may be defined either via Global Stratigraphic Section and Point (“golden spike”) locations or by adopting a numerical date. Formal adoption of this term in the near future will largely depend on its utility, particularly to earth scientists working on late Holocene successions. This datum, from the perspective of the far future, will most probably approximate a distinctive stratigraphic boundary.

A unified scale of Cretaceous stages has been generally accepted for a long time. However, the earliest stage, the Berriasian, is often replaced by the Ryazanian, reflecting the particular difficulties of correlating between the Tethyan and the Boreal Realms around the Jurassic-Cretaceous boundary.

Although the Mesozoic sediments of the Cleveland Basin (North Yorkshire) have generally not been strongly faulted, several approximately N–S trending faults have been identified along the coast. New seismic data from adjacent coastal waters has allowed the offshore extension to the fault system to be examined for the first time. The coastal faults from Peak (Ravenscar) to Red Cliff (Cayton Bay) are shown to form part of a linked system defining a narrow graben only some 5 km wide, the Peak Trough. Faulting has been complex, with decollement levels apparently developed in weak layers at various horizons in the Triassic and Permian strata: fault geometries and regional considerations suggest that extension has been dominant. Movement occurred intermittently from Triassic to latest Cretaceous or early Tertiary times.

Each of several regional or local unconformities may have been identified locally as the "late Cimmerian unconformity," a supposed major break at the base of the Valhall Formation (or Roedby Formation). Over most of the North Sea the base of the Valhall Formation is isochronous, and conformable with underlying sediments. It is detected on seismic reflection profiles because it represents a widespread facies change marking the late Ryazanian transgression. Most of the unconformities are of eustatic origin and the effects of eustatic sea level changes were never completely masked by local tectonics. Thus, in the modeling of individual oil fields, the possibility of sedimentary breaks occurring can be predicted in part by reference to regional or eustatic events.--Modified journal abstract.

Delphinites (Family Neocomitidae, Subfamily Platylenticeratinae) is described from Traill Ø and Wollaston Forland in North-East Greenland, where it is represented by two new species of the subgenus Pseudogarnieria: Delphinites (Pseudogarnieria) christenseni n. sp. and Delphinites (Pseudogarnieria) donovani n. sp. The material indicates the presence of equivalents of the Delphinites (Pseudogarnieria) undulatoplicatilis Zone of the Russian Platform, and of the Thurmanniceras pertransiens Zone of South-East France. These Greenland occurrences are therefore correlatable with the lowest biozones of the Valanginian Stage in both the Boreal and the Tethyan realms. The genus was previously known almost exclusively from the Russian Platform, and it has an essentially marginal Boreal distribution.
