The oldest human skeletal remains are the 40ky old Lake Mungo remains in New South Wales, but human ornaments discovered at Devil's Lair in Western Australia have been dated to 48 kya and artifacts at Madjedbebe in Northern Territory are dated to at least 50 kya, and to 62.1 ± 2.9 ka in one 2017 study.

One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains. This is a radiometric technique since it is based on radioactive decay. Cosmic radiation entering Earth's atmosphere produces carbon-14, and plants take in carbon-14 as they fix carbon dioxide ...
A fragment of a jawbone with eight teeth found at Misliya Cave has been dated to around 185,000 years ago. Layers dating from between 250,000 and 140,000 years ago in the same cave contained tools of the Levallois type which could put the date of the first migration even earlier if the tools can be associated with the modern human jawbone finds.
Map of the Americas showing pre-Clovis settlements. Historically, researchers believed a single theory explained the peopling of the Americas, focusing on findings from Blackwater Draw New Mexico, where human artifacts dated from the last ice age were found alongside the remains of extinct animals in 1930s [31] This led to the widespread belief in the "Clovis-first model," proposing that the ...
Researchers working at a cave in southern Spain have found evidence that the skeletal remains of ancient humans buried there were dug up, modified and even used as tools by subsequent generations.
Their investigation of the site was prompted by the finding of several bear remains (Ursus deningeri) since the early 20th century by amateur cavers (which consequently destroyed some of the human remains in that section). By 1990, about 600 human remains were reported, and by 2004 the number had increased to roughly 4,000.
The human fossils found in the layers of sediment were originally difficult to date. Between Laotian laws protecting the remains and contaminating charcoal that had washed into the cave, several ...
Scientists say they have recovered the oldest known Homo sapiens DNA from human remains found in Europe, and the information is helping to reveal our species’ shared history with Neanderthals ...
