This is fun, where it gets good. Rand, please tell which of the 33 extant animal phyla began during the Cambrian explosion. Which ones? A list would be awesome. You specified animal, but what about the fungi and plants?
Before you try you will find all of the plant and fungi are post Cambrian, as well as a number of animal taxa. But I will accept evidence of all animal taxa at a phylum level. List would be great.

You said that all animal phyla appear during the Cambrian explosion. I am asking that you account this with a list of which phyla. You did not.
There are 33 currently recognized phyla, how many of those are found in the Cambrian explosion? ABE: I know the answer to this, you do not Edited by Lithodid-Man, : To be snarky

Rand writes: Essentially except one possibility around 470 million years ago, all animal phyla had appeared or evolved around the time of the Cambrian explosion 500 million years ago. Since that time, no new animal phyla have appeared or evolved IN 500 MILLION YEARS. Sorry, I stupidly thought you would do better. Most animal phyla did not occur during the Cambrian explosion. In fact ~8 or so did out of the 33 recognized phyla. I was trying to be nice. Let you find this out. But anyway. False statement? Admit wrongness or stick to it like a good YEC?

You are ignoring that if only 8 phyla are known from the 'Cambrian explosion' then then rest of the 33 must have originated after. Bryozoa are one that comes to mind, they are critical reef animals in the Ordovician that did not exist until after the Cambrian.

Out of the 38 extant currently accepted phyla only 8 are found from the lower Cambrian or before. A simple "okay, I was wrong" will suffice. I know of course that will not happen, and my work here will somehow prove you even more right. I have decided that I will refrain from posting for awhile, just going to enjoy the current chatter as it is. References: Boardman RS, Cheetham AH, and Rowell AJ (1987) Fossil Invertebrates.

I could not let these gross insults go by, so am posting this.
First of all Rand, I do not owe fuck all of an apology to you or the board. Not one of your links showed me to be 'factually incorrect'. Like your past issues, you should probably actually read the sources you cite (by read I mean read and understand). A U-shaped burrow that resembles Echiuran burrows suggests the possibility that the phylum is Cambrian, but in no way proves it. Many other infauna make similar burrows. Also, the Chenjiang and Burgess fauna are not part of the Cambrian explosion, the former (barely) lower and the latter mid Cambrian. Understand the difference? I am a professor of invertebrate zoology, I am well aware of the evidence for a very early origin of phyla. In fact, I actually believe that most phyla did originate before or near the beginning of the Cambrian. My complaint was the blanket statement as fact that "all but one" are proven to be Cambrian. This is an extremely out of date popular belief that severely lacks evidence. The majority of extant phyla have no fossil record. For these we require the rapidly growing science of molecular taxonomy. But if you want to use that as proof of age it is married inextricably to the theory of common descent.

Look Rand, as per Percy's warning I am not going to allow you to poke me into saying something to get me banned (I suspect is your intent), although there are many many such things that come to mind.
You seem to be incapable of understanding that I BELIEVE that most if not all animal phyla originated before the Cambrian, but the actual fossil evidence is that only 8 did. See the difference?
Rand writes: Also, why the comment on the "early Cambrian"? Could it be that you realized you were wrong, and so rather than discuss the phyla that appeared in the Cambrian (even though my point rests not on when they appeared but when they stopped appearing), you realized that more than "8 phyla" had appeared in the phyla and so you tried to change the argument to a false claim, suggesting that we were only discussing the early Cambrian era? This is just outright slanderous. I hope you someday recognize how nasty this is.
Rand writes: Thus far, I have provided links detailing scientific opinion that disagrees with your claims. You have provided nothing but your assertion that because you are an invertebrate professor that you are right. This is just outright slanderous. I hope you someday recognize how nasty this is. However, if you looked at my original post to you:
