Folk memory is a term sometimes used to describe stories, folklore or myths about past events that have been passed orally from generation to generation. The events described by the memories may date back hundreds, thousands, or even tens of thousands of years and often have a local significance. They may explain physical features in the local environment, provide reasons for cultural traditions or give etymologies for the names of local places.
with its large talons. The Haast's eagle is believed to be the subject of many Māori legends
Species
Place names have been used to reconstruct the past frequency and distribution of the wolf and beaver in Great Britain, where such species are no longer present.
Māori legends of a man eating bird, known variously as the Pouakai, Hokioi, or Hakawai are commonly believed to recount Haast's eagle, a giant predatory bird that became extinct with the moa only 600 years ago. Opposing claims have been made that associate the Hokioi and Hakawai with the extirpatedCoenocorypha snipe.
Mapinguari legends of a giant sloth-like creature that corresponds with the Mylodon, which has been extinct for 10,000 years.
Legends of the bunyip within Australian Aboriginal mythology have been associated with extinct marsupial megafauna such as Zygomaturus or Palorchestes. When shown fossil remains, Aborigines identify them as those of the bunyip.
Legends throughout Eurasia describing creatures such as the unicorn may have been based upon Elasmotherium, a rhinoceros-like creature believed to have been extinct for up to 50,000 years.
The Ebu Gogo myths of the people of Flores have been hypothesised to represent Homo floresiensis, which perhaps became extinct around 10,000 BCE.
Legends from dozens of Native American tribes have been interpreted by some as indicative of Woolly Mammoth. One example is from the Kaska tribe from northern British Columbia; in 1917 an ethnologist recorded their tradition of: “A very large kind of animal which roamed the country a long time ago. It corresponded somewhat to white men's pictures of elephants. It was of huge size, in build like an elephant, had tusks, and was hairy. These animals were seen not so very long ago, it is said, generally singly, but none have been seen now for several generations. Indians come across their bones occasionally. The narrator said he and some others, a few years ago, came on a shoulder-blade... as wide as a table.” However, the animal in this story was predatory and carnivorous, suggesting the memory of the proboscideans had become conflated with that of other megafauna, such as bears and sabertooths.
Even more so than is ordinary for the study of history, the plausible historical connections listed above could be inaccurate due to the difficulty of piecing together prehistoric or preliterate fragments of evidence into a meaningful understanding. They must rely on more speculation to fill in evidence gaps than would be acceptable in another context that provided more rigorous verifiability of the records available.
