- Abstract
The article presents information on a new geological time scale invented by a team of authors. According to the authors, there are three basic components of such a timescale. The first of these is based on relative time intervals, standardized by international agreement, and involving units such as the Jurassic or the "Harpoceras falciferum" ammonite zone. The second one is a "continuous clicking clock" measured in years before present, in geological terms a matter for discovery or estimation. In the new timescale, the Precambrian and Neogene, at opposite ends of the scale, have been subjected to different approaches for entirely different reasons.
