... following mats under thin sands, they actively scavenged buried Dickinsonia , Aspidella , Funisia and other elements of the Ediacara Biota. These traces of opportunistic scavengers of dead animals from the Ediacaran of South Australia represent a fundamental ecological innovation and a possible pathway...

... including total-group poriferans and total-group cnidarians, first appear in the terminal Ediacaran, ∼550 Ma. This is followed by a substantial increase in abundance, diversity and mineralogy during the early Cambrian. The biological relationship of Ediacaran to early Cambrian skeletal biota is unclear...

... that a putative rise in oxygen levels may have provided the necessary environments for the diversification of complex body plans and energetically demanding ecologies. The potential loss of organisms with relatively high oxygen requirements in the latest Ediacaran coupled with an apparent return to low oxygen...

... and δ 18 O values reveal when five supercontinents formed through orogenic collision (vertical grey bars), leading to greatly increased reworking of sediment during magmatism [ 35 ]. ( B ) The zircon Hf [ 36 ] and seawater Sr isotope [ 37 ] records anti-correlate, confirming that the Ediacaran–Cambrian...

...Timothy W. Lyons; Mary L. Droser; Kimberly V. Lau; Susannah M. Porter; Chao Li; Meng Cheng; Maoyan Zhu; Timothy W. Lyons It is generally agreed that early diversification of animals and significant rise of atmospheric and oceanic oxygen (O 2 ) levels occurred in the Ediacaran (635–541 million years...
