Professor was right: Mastodon weapon was older than thought, scientists say

Link: Professor was right: Mastodon weapon was older than thought, scientists say

It’s not unusual for an archaeologist to get stuck in the past, but Carl Gustafson may be the only one consumed by events on the Olympic Peninsula in 1977. That summer, while sifting through earth in Sequim, Wash., the young Gustafson uncovered something extraordinary - a mastodon bone with a shaft jammed in it. This appeared to be a weapon that had been thrust into the beast’s ribs, a sign that humans had been around and hunting far earlier than anyone suspected.

Unfortunately for Gustafson, few scientists agreed. He was challenging orthodoxy with less-than-perfect evidence.
