Humans and North American megafauna coexisted in the northeastern United States for approximately 1,000 years.
Notes on verification
Confirmed by peer-reviewed study (Boulanger and Lyman 2014, Quaternary Science Reviews) and corroborated by an independent secondary source (Science.org). Some researchers dispute the dating assumptions based on other regional sites, but the core finding for the northeastern US specifically is well-supported by multiple independent sources.
