The prevailing view, on the other hand, is that birds inherited most of their

fossil record.  BCF comes up a little short in this respect. >>

Leave us not talk about the fossil record when it comes to the ground-up 
theory! ALL the most birdlike theropods appear in the fossil record AFTER 
Archaeopteryx and cannot possibly be its ancestors. In BCF, this HAS to 
happen, because the birdlike theropods >descended from< the dino-birds. The 
fossil record, taken at face value, DIRECTLY CONTRADICTS ground-up/BADD. The 
cladistics requires EVERY KNOWN theropod to have a substantial ghost lineage 
to the point of its divergence from the dinosaur-to-birds lineage. And >I'm< 
the one accused of making up fairy-tale dino-birds? Where are the Triassic 
and Jurassic maniraptoran, Deinonychus-like theropods, if they were ancestral 
to Archaeopteryx-like birds? Not only is Archaeopteryx an advanced 
maniraptoran, it is also the EARLIEST ONE known, save perhaps for a few 
small, nondescript teeth of about the same age. FEH. Fossil record indeed.

Hey, am I getting close to my seven-email quota? Yike--this one right here is
