of course the "tiny remnants of cartiligenous attachments that show up
as a stain" may be in dispute between paleontologists.
These are OLD bones after all, and they are more than a little worn, so
interpretations may differ-doesn't make it easy figuring out what info
to use on each bone.  Like figuring out whether the ptersaur's first
wing finger is really the 2nd wing finger or not. Makes it difficult to
do unless you model it both ways.  And if the actual bones don't make
you sure, they're the source of the info in the computer, so the
computer won't make you sure instead.  Garbage in, garbage out.

Oh, very likely.  Already you can do most of the stuff possible on an
SGI from 4 years ago on a really souped-up PC now, so things are
improving.
