Spriggina is a genus of early animals whose relationship to living animals is unclear. Fossils of Spriggina are known from the late Ediacaran period in what is now South Australia. Spriggina floundersi is the official fossil emblem of South Australia; [2] it has been found nowhere else.

Spriggina floundersi is the oldest fossil organism to be described with a "head". The fossil was originally described as a polychaete worm (commonly referred to as bristle worms), where subjective conclusions about its worm-like morphology were drawn from the fossil impressions.

†Spriggina floundersi. Glaessner, 1958. Genera See text. Sprigginidae is an extinct family of cephalozoans characterized by having a greater number of isomers than its sister taxon, Yorgiidae. They lived approximately 635 million years ago, in the Ediacaran period. Distribution.

Spriggina is known only from beds of Ediacaran age. Fossils from the Vindyhan, reliably dated to around 1200|million years ago, have been classified as Spriggina, but in all likelihood represent microbial artifacts.

Jul 20, 2011 · Spriggina (sprig-EE-nuh) is an odd genus of animal from the Ediacaran Period (about 600 million years ago). No one really knows what kind of animal Spriggina really was--if it was an annelid, arthropod, sea pen, or maybe even something else.

Spriggina floundersi is an extinct segmented organism from the Ediacaran period (635 - 542 Mya). It grew up to 60mm in length and was one of the earliest complex multi-cellular organisms to appear on Earth.

Spriggina floundersi was the only generally accepted species of the genus, with the name floundersi referring to amateur South Australian fossil hunter Ben Flounders. Spriggina has been found nowhere else but the Flinders Ranges.

Metaspriggina – from the Greek meta, “in company with, or later in time,” and the morphologically similar Ediacaran organism Spriggina (which is no longer thought to be related). Spriggina honours Reg Sprigg, discoverer of the Precambrian fossils of the Ediacara Hills in Australia.
