The article is from Januay 2000, so they were going wherever almost four years ago now. It deals extensively with the freezing and killing effects of the glaciation, of course.
These extreme glaciations occurred just before a rapid diversification of multicellular life, culminating in the so-called Cambrian explosion between 575 and 525 million years ago. Ironically, the long periods of isolation and extreme environments on a snowball earth would most likely have spurred on genetic change and could help account for this evolutionary burst.It also mentions an apparent extreme genetic bottleneck just before the otherwise unexpectedly late Cambrian blossoming of diversity.
Image: HEIDI NOLAND ALL ANIMALS descended from the first eukaryotes, cells with a membrane-bound nucleus, which appeared about two billion years ago. By the time of the first snowball earth episode more than one billion years later, eukaryotes had not developed beyond unicellular protozoa and filamentous algae. But despite the extreme climate, which may have "pruned" the eukaryote tree (dashed lines), all 11 animal phyla ever to inhabit the earth emerged within a narrow window of time in the aftermath of the last snowball event. The prolonged genetic isolation and selective pressure intrinsic to a snowball earth could be responsible for this explosion of new life-forms.
Hard to imagine the dead changing...

And both your statement above and what you posted evades completely my refutation above. There could have been no marine life - as we know there was (and as evolutionists themselves claim there was) if the oceans were covered with ice. So as I said, that article is ample proof of the depths of irrelevancy to which that journal has sunk while being guided by a raving evolutionist.
Lurkers might be interested in knowing that there is a dispute about the fossils:
