I have Adobe Acrobat, but my computer freezes up sometimes when trying to open PDFs. I think it's succumbing to entropy. *Wink*
My comments were directed to the thoroughness of this paper and the scientific standing of its primary author. He has taken a fossil that was somewhat ambiguous and figured out where it more likely lies in the scheme of things. That is a valuable thing to do. I was not attempting to demean you at all in this thread, as you have done nothing to deserve it (but the thread's still young!).
My point was that Walpoff seems to have straightened out a very confusing find in a very difficult time period. I find his explanation, and his evidence, credible, and I have some training in the field.
If your system is freezing up, perhaps more memory or some other slight upgrade might help? Perhaps a system upgrade would do it. (I use Macs, so I don't know a thing about most other folks' problems.)

There goes the thread!!!!
