[Coral-List] coral ancestors

[Kosmynin, Vladimir]

Hi Doug,

Thank you for sending the link to interesting article.  Just a short note on the subject of the article. Nice artistic reconstruction of fossil polyp. However, I doubt that mentioned in the article organism is the oldest known relative to living animals.  It is not the oldest known organism that can be considered a predecessor of modern Cnidaria either. Fossils of Vedian-Ediacarian time (~570-680 mln yr ago) had notions of single and colonial polyps, and meduzoid organisms from the time of description of Vendian period, and some of meduzoids were gigantic in size, like of ~ 1 m in diameter. So, just to make sure that readers of our list (those who are not paleontologists) wouldn't think that this is a new discovery of coral ancestors. Polyps of Vendian period known for 60-70 years, from the time Russian paleontologist Boris Sokolov introduced that period and described it's fauna.
I guess somebody in our list is "real" coral paleontologist and may provide better comments on modern views of coral ancestry as well as about the finding described in the article.

Best,

Vladimir N. Kosmynin
