It was related to the [[Siberia]]n ''[[Markuelia]]''. Most ''Olivooides'' fossils are in a late embryonic stage, having died before hatching.<ref>{{cite journal|last1=Bengtson, S.|title=Fossilized [[Metazoan]] Embryos from the Earliest Cambrian|doi=10.1126/science.277.5332.1645 | volume=277|journal=Science|year=1997|issue=5332|pages=1645–1648}}</ref> Some show a hatched animal, conical with a star-shape surface, and stellae. They are pertural in the peak. There is an addition of striated tissue that indicates growth. ==References== {{reflist}} [[Category:Jellyfish]] [[Category:Cambrian]] {{biology-stub}}
