The geological time scale (GTS) is a system of chronological measurement that relates stratigraphy to time, and is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history. Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The geologic time scale began to take shape in the 1700s. Geologists first used relative age dating principles to chart the chronological order of rocks around the world. It wasn't until the advent of radiometric age dating techniques in the middle 1900s that reliable numerical dates could be assigned to the previously named geologic time.

Calling this span from roughly 66 Myr to 1.8 Myr the Tertiary Period is fairly common in geologic literature. It is sometimes referred to as the "age of mammals". Lutgens & Tarbuck further subdivide this Neogene Period into the Miocene Epoch from 23.8 to 5.3 Myr and the Pliocene Epoch from 5.3 to 1.8 Myr.

The geologic column is a graphic representation of the layers of rock that make up the earth’s crust. By compiling data from local areas, scientists have constructed a composite picture of the earth. Evolutionists would have us believe that this is also a picture of the 4.5 billion year history of the earth. Several geological timescales exist, reflecting the use of differing datasets and methods of interpretation. The BGS Geological Timechart is based on The Geologic Time Scale 2012 (Gradstein et el., 2012), with additions. The result is a composite geological timechart that will be updated as improved timescales become available. Additional.

    We use this magnetic record to establish a Geomagnetic Polarity Time Scale that forms the basis for the Geological Time Scale that quantifies Earth's geological evolution. Jurassic magnetism has been difficult to quantify because of its weak signal in the Pacific leading to its characterization as the Jurassic Quiet Zone with limited polarity.

Figure 7.1.3: The eras (middle row) and periods (bottom row) of the Phanerozoic eon. The Cenozoic era, which represents the past 65.5 Ma, is divided into three periods: Paleogene, Neogene, and Quaternary, and seven epochs (Figure 7.1.4). Dinosaurs became extinct at the start of the Cenozoic, after which birds and mammals radiated to fill the. The following subdivisions and events are included on the time scale, from oldest to youngest. The oldest subdivision of the time scale is the Precambrian (symbolized by PC, X, Y, or Z in the GRI GIS data). The Precambrian is split into three eons: Hadean (4600-4000 MYA), Archean (4000-2500 MYA), and Proterozoic (2500-541 MYA). At the time the Quaternary Fault and Fold database was established (1993), the Quaternary time period was defined as <1.6 Myr in the 1983 Geologic Time Scale, published in 1983. In 1999, it was updated to 1.8 Myr, and in 2009 it was revised to 2.6 Myr. Most recently, in 2018 it was revised again to 2.58 Myr, see GSA Geologic Time Scale. November 14, 2020.

The first people who needed to understand the geological relationships of different rock units were miners.Mining had been of commercial interest since at least the days of the Romans, but it wasn't until the 1500s and 1600s that these efforts produced an interest in local rock relationships. Calling this span from roughly 66 Myr to 1.8 Myr the Tertiary Period is fairly common in geologic literature. It is sometimes referred to as the "age of mammals". Lutgens & Tarbuck further subdivide this Neogene Period into the Miocene Epoch from 23.8 to 5.3 Myr and the Pliocene Epoch from 5.3 to 1.8 Myr. Lab 7: Geologic Time Introduction ago.
