Coronacollina acula
Species of sponge (fossil)
From Wikipedia, the free encyclopedia
Coronacollina acula is an extinct species of multicellular organism from the Ediacaran period resembling the Cambrian 'sponge' Choia. The organism comprised a raised, tri-radially-symmetrical central mound with a central depression and resistant spicules (up to four in articulated fossils), which were resistant — either chitinous or biomineralized — and grew to be 37 cm long.[1]
