Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed.
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
Discovered at an oil sands mine north of Fort McMurray, Alberta, the specimen is remarkable for being among the best-preserved dinosaur fossils of its size ever found. It preserved not only the armor ( osteoderms ) in their life positions, but also remains of their keratin sheaths, overlying skin, and stomach contents from the animal's last meal.
New research shows that Homo sapiens traveled from Africa to East Asia and toward Australia up to 86,000 years ago.
A fossil jawbone found by a British girl and her father on a beach in Somerset, England belongs to a gigantic marine reptile dating to 202 million years ago that appears to have been among the ...
The 3.48 Ga Dresser formation hosts microfossils of prokaryotic filaments in silica veins, the earliest fossil evidence of life on Earth, [70] but their origins may be volcanic. [ 71 ] 3.465-billion-year-old Australian Apex chert rocks may once have contained microorganisms , [ 72 ] [ 5 ] although the validity of these findings has been contested.
The remains examined in the new study include a fragment of a humerus — the lower half of the upper arm bone — and two teeth discovered at a site known as Mata Menge, one of only two places on ...
Sue [a] (stylized: SUE), officially designated FMNH PR 2081, is one of the largest, [b] most extensive, and best preserved Tyrannosaurus rex fossils ever found, at over 90 percent recovered by bulk. [4] FMNH PR 2081 was discovered on August 12, 1990, [5] by American explorer and fossil collector Sue Hendrickson, after whom it is named
