Planolites is an ichnogenus found throughout the Ediacaran and the Phanerozoic that is made during the feeding process of worm-like animals. The traces are generally small, 1–5 mm (0.039–0.197 in), unlined, and rarely branched, with fill that differs from the host rock.[1]
Distribution
Planolites fossils have been found in Africa, Asia, Europe, Antarctica, and the Americas (with most specimens found in North America).[2][3]
