A Triceratops brow horn discovered in Dawson County, Montana, has been controversially dated to around 33,500 years, challenging the view that dinosaurs died out around 65 million years ago.
The finding radically suggests that early humans may have once walked the earth with the fearsome reptiles thousands of years ago.
Obviously, this works only for things which were once living.
This was a joint event of the American Geophysical Union (AGU) and the Asia Oceania Geosciences Society (AOGS).
One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.
Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.It appears that the researchers approached the matter with considerable professionalism, including taking great pains to eliminate contamination with modern carbon as a source of the C signal in the bones.The lead presenter was Dr Thomas Seiler, a German physicist whose Ph D is from the Technical University of Munich.Radiometric dating remains a reliable scientific method.For articles on the RATE project, see the Rate Index.However, scientists from the Paleochronology Group, who perform research relating to “anomalies of science”, maintain that dinosaurs did not die out millions of years ago and that there is substantial evidence that they were still alive as recently as 23,000 years ago.
