|This stamp issue focuses on the world's first animals - multicellular organisms, some probably relatede to worms, jellyfish, and snails, dating back some 560 million years.|
Known as Ediacaran fossils, predating dinosaurs by million of years, these creatures have a particular connection to Australia. They are named after the Ediacaran Hills of the world heritage Flinders Ranges in South Australia. This is one of the four best places in the world where fossils on these first animals can be found.
Of the 100 to 150 different species which have been discovered worldwide, between 30 and 40 are found in the Flinders Ranges. In 1946, an Australian mining geologist named Reginald C. Sprigg found fossilised imprints. The name "Ediacaran" comes from an Aboriginal world meaning "veinlike spring" of water.
