The methods the geologists used when they first developed the geologic time scale. Were studying rock layers and index fossils worldwide. By Patrick
The discovery of plagioclase is not attributed to a single individual, as it is a common mineral found in various geologic settings. It was likely first observed and identified by multiple geologists and mineralogists over the years.
Precambrian time
Geologists use several methods to understand Earth's history, including radiometric dating, which measures the decay of isotopes in rocks to determine their age. They analyze rock layers and fossils through stratigraphy to reconstruct past environments and life forms. Additionally, plate tectonics theory helps explain the movement of Earth's crust and its impact on geological features over time. Finally, studying meteorite impacts and geological formations provides insights into significant events in Earth's history.
Most geologic periods are named for the location where rock formations were first found that contained fossils from that period, some others (e.g. Carboniferous) were named for materials associated with the fossils.

Penguins first appeared during the Paleocene epoch, which is part of the Cenozoic era in the geologic time scale. This period lasted from about 66 to 56 million years ago.
Historical geologists divide the history of the earth into for units of time called Eras. The first one that began when the earth formed---- 4.6 billion years ago---- was called the Precambrian Time. The next--- after the PT--- was known as the Paleozoic Era. The third--- when dinos roamed--- was called the Mesozoic Era. The on we live in is called the Cenozoic era.
Abundant and diverse fossils first appeared in the Cambrian era, although there is fossil evidence throughout much of the Precambrian.
Geologists use seismographs. They try to see when an earthquake is going to occur.
