Evidence and cases
Sourced entries. A listing is not a confirmed animal.
- Patterson-Gimlin film (Oct 20, 1967, Bluff Creek, CA) — The most famous footage; subject of many authentication and debunking attempts.
- Skookum cast (2000, near Mount Adams, WA) — A plaster cast of a body imprint in a mud wallow. Proponents argue for Bigfoot; scientific analysis says most likely an elk.
- Sykes et al. 2014, hair-sample DNA survey (Proc. R. Soc. B) — The first systematic genetic survey, covering 30 hair samples attributed to anomalous primates. All 18 US samples (AZ, CA, MN, OR, TX, WA) matched known species: black bear 5, wolf/coyote/dog 4, cow 3, and one each of raccoon, sheep, porcupine, deer, horse and human.
- Minnesota Iceman — A 1960s-70s sideshow 'missing link' frozen in ice. It is now considered an elaborate hoax; it was sold on eBay in 2013.
- Bigfoot trap (1974, Rogue River-Siskiyou NF, OR) — A cabin-sized trap built in 1974 that caught no Bigfoot and was abandoned in the early 1980s. It is now a trail destination.
- Gigantopithecus blacki extinction study (Nature, 2024) — Dates the demise of the largest known ape in southern China to roughly 295,000-215,000 years ago. Often invoked, and disputed, as a Bigfoot ancestor.
