Ruaridh Alexander, PhD student: Reconstructing the enigmatic Ediacaran organism Namacalathus
The late Ediacaran period (ca. 574-539 million years ago) hosts the rise of animals in the fossil record, including the first skeletal forms, prior to the 'Cambrian Explosion' of life. Recent studies suggest that many Ediacaran fossils may be related to groups that are historically interpreted as having originated in the Cambrian, thus deepening the roots of the 'Cambrian Explosion' and questioning the explosive nature of this evolutionary event. One such fossil is the biomineralising Namacalathus hermanastes, initially described from the Nama Group in Namibia, where recent interpretation of its biological affinities suggests placement within the bilaterians. This talk will discuss recent research into the affinities of Namacalathus and the techniques used to make such interpretations.
