Excavations at an underwater sinkhole in Florida have yielded stone tools and butchered mastodon remains dating back 15,500 years. This discovery provides compelling evidence that humans inhabited North America at least 2,000 years before the Clovis culture, long thought to be the first settlers of the continent.
Researchers utilized sub-aquatic archaeological techniques to recover the artifacts from the sediment. The presence of specialized bifacial tools suggests a high degree of technological adaptation to the unique environment of the late Pleistocene, reshaping our understanding of the first Americans.
