Pentaradial eukaryote suggests expansion of suspension feeding in White Sea-aged Ediacaran communities

Abstract Suspension feeding is a key ecological strategy in modern oceans that provides a link between pelagic and benthic systems. Establishing when suspension feeding first became widespread is thus a crucial research area in ecology and evolution, with implications for understanding the origins o...
