Tucked deep within a West Texas cave, archaeologists discovered what is likely the oldest intact weapon system ever found in North America. The roughly 6,500-year-old pieces include spear shafts, dart tips, and a lethal boomerang. A collection of 6,500-year-old wooden dart tips found deep within a Texas cave were likely, at one point in their usage, destined to be tinged with poison. Those darts were just part of an ancient hunting kit discovered by archaeologists—likely the oldest intact weapons stash ever found in North America. “We quickly found out that it’s really, really, really deep in that part of the site,” Schroeder told the New York Times.
