A startling discovery in Oregon is now challenging the very timeline of human origins. Archaeologists uncovered ancient fossilized footprints that appear to push back the arrival of humans in the Americas by thousands of years, far earlier than long-held scientific models permitted.

In 2008, researchers reported finding fossilized human feces in a cave in southern Oregon dating to roughly 14,300 years ago. The finding challenged the long-held scientific consensus that humans first arrived in the Americas around 13,000 years ago. The material was found in the Paisley Five Mile Point Caves in Lake County, a series of shallow openings in a volcanic ridge near the dried bed of Su…

Archaeologists excavating beneath a California highway stumbled upon a find they say could rewrite human history. The discovery, buried deep under layers of soil and asphalt, appears to predate known settlement timelines by thousands of years.

During a routine highway expansion project in California, construction crews uncovered a deposit that was not identified in any prior geological or archaeological assessment of the corridor. The discovery halted work, brought in teams of archaeologists, and produced dating results that have since presented a significant challenge to established thinking about when humans first arrived in the Ameri…
