From 13 million to 25 million years ago

Usage examples of miocene.

The scraper of the Esquimaux and the Andaman islanders is but an enlarged and improved edition of the Miocene scraper.

The Origin of Species, many scientists found incised and broken bones indicating a human presence in the Pliocene, Miocene, and earlier periods.

The Miocene deposits found within twelve degrees, or a little more than seven hundred miles, of the north pole, and fairly within the realm of lowest temperature which now exists on the earth, show by the plant remains which they contain that the conditions permitted the growth of forests, the plants having a tolerably close resemblance to those which now freely develop in the southern portion of the Mississippi Valley.

For example, there is an almost total absence of fossils linking the Miocene apes such as Dryopithecus with the Pliocene ancestors of modern apes and humans, especially within the span of time between 4 and 8 million years ago.

Even if anatomically modern humans were found to have lived a million years ago, 4 million years after the Late Miocene disappearance of Dryopithecus, that would be enough to throw out the current accounts of the origin of humankind.

Even if we were to propose that some primitive creature like Homo habilis made the Miocene tool, that would still raise big questions.

The Silurian period follows the Ordovician, and the Miocene epoch follows the Oligocene as surely as Wednesday follows Tuesday.

At one point in the history of paleoanthropology, several scientists who believed in evolution actually accepted the Thenay Miocene tools, but attributed them to a precursor of the human type.

Dyals, huge birds closely resembling the Phororhacos, the Patagonian giant of the Miocene, remains of which have been found on the outer crust.

The first fossil evidence of a brain of even vaguely human aspects dates back to eighteen million years to the Miocene Period, when an anthropoid ape which we call Proconsul or Dryo-pithecus appeared.

We saw the huge Miocene pig Dinohyus, as tall as a man and almost as massive as a hippopotamus, the largest of land-dwelling swine.

This was my first word of the discovery, and it told of the identification of early shells, bones of ganoids and placoderms, remnants of labyrinthodonts and thecodonts, great mosasaur skull fragments, dinosaur vertebrae and armor plates, pterodactyl teeth and wing bones, Archaeopteryx debris, Miocene sharks’ teeth, primitive bird skulls, and other bones of archaic mammals such as palaeotheres, Xiphodons, Eohippi, Oreodons, and titanotheres.

Finally, VIII and IX, the Oligocene and Miocene Epochs of the Tertiary Period, mark the emergence of man's earliest ancestors.

From the flora and fauna on the tapes, she would have placed Klairos somewhere in the late Tertiary period on the Terran-based geological time scale: late Miocene or early Pliocene.
