我閱讀過Mistaken Point 生物群的文章後，有些地方好像有點混亂，文章提及Mistaken Point 是最早的多細胞生物群，但其實埃迪卡拉動物群Ediacaran fauna 是5.8-6億年前，理應比Mistaken Point 早

有進化的

回復 #22 達爾文的帖子

Ediacaran biota refer to different assemblage of late proterozoic muliticellular life rather than biota found only in Ediacara, Australia (I know this naming system is a little bit confusing) and mistaken point is considered as one of the oldest assemblage. In one of the article here, it said that the similar form of organism can be date back to around 610mya while mistaken point is more recent biota of older organism (I remember that they may have found or dated an older assemblage, thru i cannot find the article now)

I cannot put the two paper about the detail of ediacaran biota here, maybe I can send you guys via message or email

This weekend we have a seminar on how Snowball Earth in Cryogenian period contribute to Ediacaran radiation and evolution of multicelluarity, I will let you know about the seminar when I back

P.S. I am going to a research in Congo Basin for a month next Wed. I may not able to respond you guys until late Feb, but feel free to raise anything for discussion here
