Spriggina

Spriggina floundersi, life restoration at MUSE - Science Museum in Trento

Fossils of Spriggina are known from the Ediacaran period, around 550 million years ago. The segmented organism reached about 3–5 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.
