HOW BIG IT WAS

Dickinsonia relative size depiction as described below
This fossil of Dickinsonia is about 4 cm long.

Dickinsonia was roughly oval in shape with rib-like segments emerging from a central groove or ridge.  The fossil impressions of Dickinsonia have led some palaeontologists to interpret them as having a ‘quilted’ body structure, similar in some ways to a quilted air mattress. It is not clear which end was the front. Some fossils of Dickinsonia have been interpreted as having traces of possible internal tissue.
