'''''Ikaria wariootia''''' adalah contoh awal organisme [[bilateria]] yang mirip cacing dengan panjang 2–7 mm (0,1–0,3 in). Fosilnya ditemukan di [[Australia Selatan]] yang diperkirakan berusia 555 juta tahun. Itu terjadi dalam periode [[Ediakara]], sekitar 14 juta tahun sebelum [[Kambrium]], ketika [[Letusan Kambrium|ledakan Kambrium]] terjadi, dengan bilateria menjadi sangat luas.<ref name="guardian2">{{Cite news|last1=Davis|first1=Nicola|date=23 March 2020|title=Fossil hunters find evidence of 555m-year-old human relative|url=https://www.theguardian.com/science/2020/mar/23/fossil-ikaria-wariootia-bilateral-organism-human-relative|newspaper=The Guardian}}</ref><ref name="Mphys2">{{cite web|date=March 23, 2020|title=Ancestor of all animals identified in Australian fossils|url=https://m.phys.org/news/2020-03-ancestor-animals-australian-fossils.html?fbclid=IwAR358oTBl7yey2S_W4deZ-83BwYgvfUsvVo4G4o3v7Nk6jtQq7huYBGl6m8|publisher=m.phys.org}}</ref><ref name="ehgehl2">{{cite journal|last1=Evans|first1=Scott D.|last2=Hughes|first2=Ian V.|last3=Gehling|first3=James G.|last4=Droser|first4=Mary L.|date=23 March 2020|title=Discovery of the oldest bilaterian from the Ediacaran of South Australia|journal=Proceedings of the National Academy of Sciences|volume=117|issue=14|pages=7845–7850|doi=10.1073/pnas.2001045117|pmc=7149385|pmid=32205432}}</ref>
