Is there some difference that makes the transitional forms more resistant to fossilization than their non-transitional counterparts?

One problem with trying to answer that is that there is no sharp dividing line between "transitional" and "non-transitional". A species is "transitional" if it (or a close relative) produces descendants significantly different than itself; that isn't even a property of the species itself at the time of fossilization, it's a historical occurance afterward.

Just to get a feel for your position, if we say that 100% is every living creature that ever existed then what % would you say are represented in the fossil record?

I.E what % of all living creatures fossilize?

I recall reading a few years ago that the number of fossil finds that had been studied was around 250 to 500 million. Since quite a few species have multiple finds, the number of species represented would be a good bit less than that.

I wonder how many species have lived in the last 500 million years - would that be more or less than 500 million?
