Dickinsonia menneri

Dickinsonia menneri is a species in the genus Dickinsonia. Like other proarticulata, it has a bilaterally symmetric body made up of isomers.

This species is small, with a small number of isomers and a well-marked head. Because of this, it resembles juvenile Dickinsonia costata, though it is slightly elongated compared to them.

Preserved Dickinsonia menneri are found in the White Sea and Ediacaran assemblage.

Mode of Life
Dickinsonia menneri lives on the seafloor, unmoving but also unattached. It feeds by absorbing nutrients from the seawater.

Time Period
Dickinsonia menneri lived between 558 and 555 million years ago, in the Ediacaran 3 Age of the Ediacaran Period.
