context_page_description: Armillifera is an Ediacaran marine animal, that existed on Earth about 555 million years ago. It was first described by the author Mikhail Fedonkin in 1980. Its fossils were discovered in the White Sea area, Arkhangelsk Region, Russia. The fossils of Armillifera were restricted to almost the same stratigraphic range as Kimberella, but was very rarely found.
context_section_description: Armillifera is bilaterally symmetric, oval shaped. It's convex in the center with a flattened surrounding band, and its surface is covered by numerous tubercles fused on the band to form rounded ridges. The surface of its central region possesses deep hook-shaped depressions, that are arranged accordingly to glide reflection symmetry.
