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;
