Extensive metazoan reefs from the Ediacaran Nama Group, Namibia: the rise of benthic suspension feeding

, 2015
We describe new, ecologically-complex reef types from the Ediacaran Nama Group, Namibia, dated at ~548 million years ago (Ma), where the earliest known skeletal metazoans, Cloudina riemkeae and Namacalathus formed extensive reefs up to 20 m in height and
