The "Right" order is the order of ages with millions of years of variance between them. Here is an example of fossils in the wrong layer http://www.answersingenesis.org/docs/485.asp

Why are they in the wrong layer? Ostracoderms like Anatolepis were the earliest known true vertebrates and have been known for over 100 years.

In fact, IIRC, the main debate was whether Anatolepis was a vertebrate or not, that's all. The link you cited is dishonest in some ways as it makes a false claim. No one in palaeontology was worried whether vertebrates could exist in the Cambrian or not, it's just that earlier techniques could not prove whether Anatolepis was a vertebrate or invertebrate.
