 The single, 1 cm-long fragment of "P. newmani "depicts small paranota (keels) high on the body, long, slender legs.The dorsal portion of each body segment is ornamented with a horizontal bar and three rows of roughly hexagonal bosses (bumps).The fossil is important because its cuticle contains openings which are interpreted as spiracles, part of a gas exchange system that would only work in air.
