Bomakellia kelleri is a species of poorly understood Ediacaran fossil organism represented by only one specimen discovered in the Ust'-Pinega Formation of the Syuzma River (in Arkhangelsk Oblast, Russia) from rocks dated 555 million years old. Bomakellia was originally interpreted as an early Arthropod.[1] A study by B. M. Waggoner even concluded that the organism was a primitive anomalocarid and erroneously identified the ridges of supposed Cephalon as being eyes making Bomakellia the oldest known animal with vision.[2] But this hypothesis has not reached acceptance, nor acknowledgement.[3][4]
A closer examination of the specimen has identified a tetraradial symmetry in the body, and a frond-like morphology which closely resembles that of Rangea – the current interpretation of Bomakellia is as a rangeomorph frond, which could possibly mean that it's closely related to the Chinese Paracharnia.[5]
