Pre-Clovis Megafaunal Hunters

The Manis Mastodon site, reported in Science today, is throwing (yet another) curve ball into what scholars understand about the founding populations of North America.

You can clearly see the bone point that penetrates into the rib. It has been sharpened to a point. The tip of the point broke off after impact and rotated a bit. You can also see how some of the bone point failed and scissored. Image courtesy of Center for the Study of the First Americans, Texas A&M University

Until about 15 years ago, the mainstream archaeological community largely agreed that the first people who occupied North America were big-game hunters called Clovis people, who crossed the Bering Strait from northeastern Asia no earlier than 11,200 years ago. In 1977, the Monte Verde site at the tip of the South American continent was discovered: a site predating all Clovis sites by some two thousand years, and some 15,000 kilometers south of Bering Strait.

Since that time, many other sites older than Clovis (now called "pre-Clovis", for want of a better term) have been identified in both North and South America. We still believe, more or less, that the entry way was across the Bering Strait, but the living strategies of pre-Clovis have turned out to be far more diverse than simply big game hunters. Pre-Clovis people were hunter-gatherer-fishers, meaning that they ate game, fish and plants, as the occasion warranted.

Manis Mastodon is a site on the Pacific Coastline of Washington State, and it is one of a handful of sites that suggest that the omniverous pre-Clovis also dabbled in megafaunal hunting strategies. Ayer Pond, in Washington State very near Manis, is a pre-clovis site where workmen discovered a butchered bison. Fenske, Mud Lake, Schaefer and Hebior are four sites in Wisconsin that represent woolly mammoth hunting/butchering at pre-clovis dates.
