Such gigantism may have originally evolved in response to the environment, which was increasingly arid as the Pleistocene epoch
The finding suggests that a giant iron asteroid smashed into what is today a glacier during the last ice age, an era known as the Pleistocene Epoch
that started 2.6 million years ago.
Geology buffs can also explore glacial features along Wisconsin's 1,200-mile-long Ice Age Trail or avoid them altogether in the Driftless Area, a region mysteriously untouched by the massive ice sheets of the Pleistocene Epoch
. Profusely illustrated, impressively informative, thoroughly 'reader friendly' in organization and presentation, "Wisconsin Rocks!" is a 'must' for all Wisconsin school and community library collections.
Even when I was training back in the Pleistocene epoch
, old Doc Greenberg was a throwback.
'Our excavations at Kalinga and the numeric dating results clearly provide securely dated evidence for human colonialization of the Philippines by the early Middle Pleistocene epoch
(777,000 to 631,000 years ago), and long before the appearance of modern humans in both the local context and wider Island Southeast Asia region,' his report read.
in the Pleistocene epoch
and herd them into special nature reserves." The enterprise was a disaster, its only achievement being "a small pride of lions, which finally provided the substrate for [a far more ambitious] experiment: the creation of the Gente," the species that will supplant humanity.
The study claimed the prints were proof that humans managed to navigate waters and make their way to Canada's coast at the tail end of the Pleistocene epoch
, or the last time large parts of the planet were frozen over.
In our investigations, layers deeper than 1 meter, which are in the permafrost state for a long time, were of great interest, with the accumulation of soil organic matter (SOM) occurring not only in the active layer, in the present stage of soil formation, but also in the permafrost sequences of the Pleistocene epoch
, which may include significant archaic quantities of OC, N, and other components of SOM.
The ranger followed this up with an informative lecture in which I learned that these limestone caves were already growing and ancient by the end of the Pleistocene epoch
, perhaps one hundred thousand years ago, carved by sedimentary and metamorphosed (marble) limestone being dissolved by ground water of high mineral content (carbonic Acid).
Davis narrates the history of the Gulf of Mexico from its origins in the Pleistocene epoch
and its flourishing aboriginal cultures--still evident in burial and ceremonial mounds.
Modern humans emerged during the Pleistocene Epoch
about 200,000 years ago, though the rise of civilization took place during the Holocene.
