From: Centimeter-wide worm-like fossils from the lowest Cambrian of South China
Vittatusivermis annularius gen. et sp. nov. from the lowest Cambrian of the Baideng section, Anning, Yunnan, South China, showing folding structures and differentiation of both sides of the flattened body. (a) L1070410, folded lengthwise, resulting in a folded edge proximately perpendicular to the body length, the overlapping body part curved and showing a constriction in body width probably originated from a fold along the body length. (b) L1070389, folded obliquely, the folded edge intersecting the body length in a obtuse angle.
