Bergaueria

From Wikipedia, the free encyclopedia

Bergaueria
Temporal range: Ediacaran – Ludlow
Bergaueria radiata
Trace fossil classification Edit this classification
Ichnogenus: †Bergaueria
Prantl, 1946

Bergaueria is an Ediacaran–Silurian[1] trace fossil believed to represent the dwelling trace of Cnidarians (Actinia – sea anemones).[2] It likely caused mixing and fluid exchange into the sediment (bioirrigation).[3] Similar traces (Cheiichnus) can be made by rotational movement of arthropods.[4]
