The segmented organism reached about 3 cm in length and may have been predatory. Its bottom is covered with two rows of tough interlocking plates, while one row covered its top; its front few segments fused to form a head, which may have borne eyes and antennae. Spriggina's affinity is currently unknown; it has been classified as an annelid worm, a rangeomorph-like frond, and an arthropod, perhaps related to the trilobites. Lack of known segmented legs or limbs tends to make an arthropod classification premature."@en . . . . "#"@en . "Spriggina floundensi"@en . . "Glaessner, 1958"@en .
