For the symbol used to mark a taxon as extinct, see Dagger (mark).
The extinction symbol with an X-shaped pictogram of an hourglass. The letter X stands for the first syllable of the word "extinction"Flag with the extinction symbol
The extinction symbol represents the threat of holocene extinction on Earth; a circle represents the planet and a stylised hourglass is a warning that time is running out for many species.[1][2] The symbol dates to at least 2012 and has been attributed to anonymous East London artist Goldfrog ESP.[1][3][2] The symbol has been called "this generation's peace sign".[1] It is used by environmental protesters, and has been incorporated in works by artists and designers such as Banksy.[4][5] In 2019, the Victoria and Albert Museum acquired a digital copy of the symbol, and other artifacts featuring the symbol, for its permanent collection.[6][7][8]
