This is simply some bookkeeping for the blog; nothing new here. This is being done to update the "Geology" section of the blog.

Time Scales
Note: geologic time periods are named differently than archaeological time periods.
A quick reminder:
- Phanerozoic eon
- Paleozoic era
- Mesozoic era (Triassic/Jurassic/Cretaceous periods)
- Cenozoic era (Paleogene/Neogene/Quarternary periods)
- Quarternary period
- Pleistocene / Holocene epochs
- Pleistocene epoch
- spanning the world's most recent period of repeated glaciations.
The end of the Pleistocene corresponds with the end of the last glacial
period and also with the end of the Paleolithic age used in
archaeology.
- Gelasian / Calabrian / Middle / Late ages
- The above, geologic time, in millions of years:
- the previous epoch (the Pleistocene epoch) from about 3 million years to the present epoch (the Holocene epoch);
- the Gelasian age: about 3 million to 2 million years ago
- the Calabrian age: about 2 million to 1 million years ago
- the middle age (Chibanian Age) of the current epoch began about 800,00 years ago;
- the late age (the Tarantian Age, proposed name) of the Pleistocene Epoc began about 130,00 years ago
- The current epoch (the Holocene epoch)
- the earliest age (the officially ratified Greenlandian age) then began about 11,700 years ago
- the middle age (the Northgrippian age)
- the current age (the Meghalayan age): c. 2250 BC to the present
The Historical Ages
The Meghalayan age is now further divided into "historical ages":
Stone Age
Bronze Age: 3300 BC - 1200 BC (ended with the Fall of Troy)
Late Bronze Age: - 1200 BC
Iron Age: 1200 BC - 500 BC (Homer during the mid-to-late Iron Age)
Viking Age: 500 BC -- 800 AD (Pre-Roman, Roman, Germanic)
Pre-Roman: 500 BC - 0
Roman: 0 - 400 AD
Germanic: 400 AD - 800 AD
The Middle Ages: 1100 - 1453 AD
The period of European history from the fall of the Roman Empire in the
West (5th century) to the fall of Constantinople (1453), or, more
narrowly, from c. 1100 to 1453.
Reformations:
16th and 17th centuries.
The Enlightenment:
The Enlightenment – the great 'Age of Reason' – is defined as the period
of rigorous scientific, political and philosophical discourse that
characterised European society during the 'long' 18th century: from the
late 17th century to the ending of the Napoleonic Wars in 1815.
British Romanticism:
1780 -1830
The Age of Shibboliths;
