1. Period

   A geologic period is a time unit subdivision of geologic time defined as a span of years into which the larger era time units are divided into smaller timeframes, as Era's divide the Eon. In the Earth Sciences rocks and especially the sequences of rocks called stratum arrayed in an ordered "rock column" occurring during a timespan are the focus of study so the time units are paired with corresponding Rock strata units whose characteristics define such points elsewhere that occurred concurrently as the local rock layers were laid down as sediments. For the Geological Period the paired rock strata term, a geologic stage is used to denote the corresponding rock layers of both the geologic record and the fossil record; thus the rocks of the Devonian System were laid down during the Devonian Period, and such equivalent units exist at each level of refinement of geological chronology and biogeological or stratigraphic classification. Each unit of strata, no matter how interrupted the record recorded in the local rock column, is mapped into the overall geologic record and classified carefully into chronological units of geologic time based on world wide efforts of the International Commission on Stratigraphy working to correlate the world's local stratigraphic record into one uniform planet wide benchmarked system, in a steady effort ongoing since 1974. While paleontologists often refer to faunal stages rather than geologic periods, they are often used in popular presentations of paleontology or plate reconstructions.

4. Matija Cuk:

   But that fact allows us to use computer simulations to tease out the history of Saturn’s inner moons, doing so, we find that they were most likely born during the most recent 2 percent of the planet’s history. Related : Saturn's largest moon Titan is bursting with color Researchers had long thought Saturn’s rings were as old as the planet itself. But that thinking changed in 2012, when French astronomers found that tidal effects – the gravitational interaction of the inner moons with fluids deep in Saturn’s interior – are causing them to spiral to larger orbital radii comparatively quickly. The implication, given their present positions, is that these moons, and presumably the rings, are not so old. That still did n’t answer exactly when they were born. Cuk and his team turned to results from NASA’s Cassini mission, which has observed ice geysers on Saturn’s moon Enceladus. Assuming that the energy powering these geysers comes directly from tidal interactions and that Enceladus ’ level of geothermal activity is more or less constant, then the tides within Saturn are quite strong. According to the team’s analysis, these would move the satellite by the small amount indicated by the simulations in only about 100 million years. Related : Cassini probe takes' cosmic bulls-eye' of Saturn moons Enceladus, Tethys This would date the formation of the major moons of Saturn, with the exception of more distant Titan and Iapetus, to the relatively recent Cretaceous Period, the era of the dinosaurs.
