Topic: Palaeos: Time: Geological Timescale

Introduction. Although (as explained in the parent unit (more inclusive unit) of this topic) there are many possible timescales (which range from the very long (billions of years) to the very short) , Geological time, which deals in millions or tens of millions of years, is the main focus here at Palaeos. Therefore this page provides the starting point for an overview of Earth history.

Scientists: Geological evidence shows the Great Sphinx is. “The problem of dating the Great Egyptian Sphinx construction is still valid, despite of the long-term history of its research. Geological approach in connection to other scientific-natural methods permits to answer the question about the relative age of the Sphinx.

How Fossils are Dated, by Glen Kuban - Paleo The age of a fossil may be specified in both relative terms (how old it is in relation to other fossils or rock units) and in absolute terms (approximately how many years old it is). One principle of relative dating is called superposition, which holds that in any one place, the lower rock layers (and fossils in them) are older than higher ones, unless there is evidence that the layers have.

The Institute for Creation Research Twentieth-century geologists taught the familiar maxim: 'The present is the key to the past.' But now that catastrophic processes are widely employed to describe the strata record, twenty-first century geologists are wondering whether 'marine flood sedimentation is the key to the past.' Geological.

STRATA Terminology correlative conformity. forced regression. hiatus. sequence. sequence boundary. type 1 sequence boundary. type 2 sequence boundary. A surface of erosion or non-deposition separating younger strata from older rocks, along which there is evidence of subaerial erosional truncation (and, in some areas, correlative submarine erosion) or subaerial exposure, with a significant hiatus indicated.
