Geologic Time – Period prior to humans. 4.6 billion to 3 million years ago. (See "prehistoric periods" for more detail into this.) Primatomorphid Era – Period prior to the existence of Primatomorpha; Simian Era – Period prior to the existence of Simiiformes; Hominoid Era – Period prior to the existence of Hominoidea
This list of historical fiction is designed to provide examples of notable works of historical fiction (in literature, film, comics, etc.) organized by time period.. For a more exhaustive list of historical novels by period, see Category:Historical novels by setting, which lists relevant Wikipedia categories; see also the larger List of historical novels, which is organized by country, as well ...
The time covered in individual years covers Renaissance, Baroque and Modern literature, while Medieval literature is resolved by century. Note: List of years in poetry exists specifically for poetry. See Table of years in literature for an overview of all "year in literature" pages. Several attempts have been made to create a list of world ...
The Tonian (from Ancient Greek: τόνος, romanized: tónos, meaning "stretch") is the first geologic period of the Neoproterozoic Era. It lasted from 1000 to 720 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined by the ICS based on radiometric chronometry.
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch / Series . Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago).
Geologic time is the timescale used to calculate dates in the planet's geologic history from its origin (currently estimated to have been some 4,600 million years ago) to the present day. Radiometric dating measures the steady decay of radioactive elements in an object to determine its age. It is used to calculate dates for the older part of ...
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks).
Knowledge of precise climatic events decreases as the record goes further back in time. The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier periods and events come from geology and paleontology.
