Praecambridium sigillum ("Sigil of the Precambrian") was a segmented trilobite-like arthropod from either the Late Precambrian or Lower Cambrian of Ediacara Hills, Australia, about 590 to 530 million years ago. This beast is known from 13 specimens. On average, P. sigillum had at least 5 segments, each becoming progressively larger as they approach the cephalon.
