The Ediacaran Weng'an biota in South China hosts exceptionally preserved eukaryote fossils, including various acanthomorphic acritarchs, pseudoparenchymatous thalli, tubular microfossils, and spheroidal fossils such as Megasphaera, Helicoforamina, Spiralicellula, and Caveasphaera. Many of these fossils have been interpreted as …BST fossils from the Ediacaran usually fall into two categories: multicellular algae, like seaweed, and fossils that are extremely difficult to classify, often the remains of extinct types of organisms. Consequently, Dornbos said, determining exactly what is preserved in Ediacaran fossil deposits can be hotly contested.This massive diversification of life occurred around 541 million years ago; it's when most of the major animal groups appear in the fossil record.
