I thought it was interesting to see that these animals seem to be still around in some form and have lasted longer than any ocean in which they live.

Really? To me, it's the same ocean. It's the land that's moved around. The oceans that we know are just names we give to various bits of the ocean.

Interesting article, thanks for posting.

What slightly surprised me about it was the lack of any reference to the Ediacaran biota. I was expecting them to have suggested that some of those enigmatic fossils may have been the forerunners of the first ctenophores. I realise we do not really know yet whether any of these were animals, rather than plants or fungi, but I find myself wondering whether these researchers might be in a position to comment on whether the Ediacaran biota could fit into their scheme, or whether perhaps they can say that they do not, i.e. they are another branch entirely.
