A peculiar structure found in the Archaean limestones of Canada and other regions: According to some geologists, eozoon is believed to be a species of gigantic "Foraminifera", but others consider it a concretion, without organic structure.

Many of them have perforated walls, whence the name. Some species are covered with sand.
