- Below is the page I posted, (and got blocked for by User:Conservative, so I'd better not post it again). It's hardly exhaustive, but it is factual, and and referenced (linking to some nice informative sites), and it is at least the beginning of an article on the Cambrian period. Maybe someone else can take it further. I place it here simply as the basis for further discussion. --Jeremiah4-22 13:10, 7 May 2007 (EDT)
- The article below looks good to me ... I say put it back. Jrssr5 13:16, 7 May 2007 (EDT)
- So who wants to get banned for doing it? Knowing that it will be reverted immediately, also? I suppose the real "problem" with it is all that "millions of years ago" stuff, without a YEC refutation of some sort. Or perhaps it needs to say something like "Most geologists believe..." or some such qualification. It's a pity that it got killed, as I was going to use the article as a launch point sometime to create articles about those red-linked invertebrates. Human 17:26, 8 May 2007 (EDT)

The current article, and all other epoch articles currently "improved" by Conservative are ridiculous. Cutting and pasting a pointless YEC critique and a list of YECaganda websites to each and everyone seems silly at best. QNA 19:53, 16 May 2007 (EDT)
The Cambrian period was the first period of the Paleozoic era. Following on from the Pre-Cambrian, it lasted from approximately 543 million years to about 490 million years ago. It was followed by the Ordovician period. The Cambrian was named by the geologist Adam Sedgwick for Cambria,[1] Latin for Wales, which has large areas of rock originating in, and characteristic of, the period.
The Cambrian Radiation gave rise to almost all living phyla, but often in extinct forms with small resemblance to typical living species. Common Cambrian fossils are of trilobites, and inarticulate brachiopods,[2] corals and primitive echinoderms. They also include the first vertebrates, primitive jawless fish.
Since many of the organisms of the Cambrian were soft-bodied invertebrates, fossil remains other than shells or carapaces are rare; one notable site for soft-bodied Cambrian invertebrate remains is the Burgess Shale of British Columbia.[3]
