The Pleistocene epoch coincides with the start of the Quaternary period and roughly the start
of glaciation, nearly 2 million years ago, continuing until roughly 12,000 years ago. The term
"Ice Age" is often used to describe the Pleistocene epoch, but the name is somewhat
misleading since ice did not advance and remain in this period; rather, it was a time period
in which there were many glacial advances separated by periods of warmer climates. Also, not all ice
formed in this time period; the Antarctic ice sheet is estimated at 14 million years, far before
glaciation on the continents. Study of data from ice sheets found correlation between when glaciers
advanced or retreated and geometry details of Earth's orbit (eccentricity of orbit and precession of
the Earth's rotation axis). The data suggest that temperature could be further affected by
concentrations of greenhouse gases (carbon dioxide, methane). For the past 10,000 years or so, the
average temperature recorded in the ice hasn't varied more than a degree or so, but in the
Pleistocene epoch, average temperatures could be as much as 8 degrees lower with much greater variance.
The elements in this necklace and bracelet represent life emerging following the cooler periods of
glaciation and rough hewn wheels and irregular silver nuggets represent early work of humans.
Unfortunately, I had my epochs mixed, and it wouldn't be until the Holocene epoch that use of
wheels and tool-making become evident. Still, it's a great set that features an unusual material (ruby
fuchsite) with some terrific Hill Tribe silver focal pieces.
