The four eras this timeline exposes

  1. Before 1880 — the naming era. Words and traditions accumulate (bahnyip 1812, Selma 1750, Storsjöodjuret 1635, the annals 1345). No institutions, no investigations; the animals live in language, not in files.
  2. 1880–1950 — the colonial and museum era. Real animals arrive through empire and museums (okapi 1901, mountain gorilla 1902, Komodo 1912, coelacanth 1938) — and so do the great hoaxes and photographs (de Loys 1920/29, Surgeon's photograph 1934, Trunko 1924). Nobody can yet test a claim.
  3. 1950–1990 — the state looks, briefly. Nepal regulates Yeti permits (1959); the Soviet Academy convenes a snowman commission (1950s); China sends state expeditions for the yeren (1976–81); the FBI runs hair through a forensics lab (1976–77); Sweden legislates a lake monster into an endangered species (1986); the FBI, Whitehall and the FBI's successors all write files. Every one of these programmes ends in the same place: a known animal or no animal.
  4. 1990–2026 — the test era and the tourism era, running together. Genetic and genomic methods arrive (chupacabra DNA 2007, yeti 2017, Ata 2018, Loch Ness eDNA 2019, thylacine modelling 2023) and they keep naming bears, coyotes and eels. Simultaneously the cryptid becomes an economic asset: sanctuaries, coat-of-arms serpents, municipal bounties, 7–6 authentication votes, a register with 1,165 entries and three sightings in a year. The evidence has never been better and the incentive to resolve nothing has never been stronger.
