We have seen that the dino-to-bird based cladograms are not congruent with the fossil record.
The dino-to-bird enthusiasts say that is because the fossil record is incomplete.
But here is an interesting thing that comes to light in the Wills et al (2008) study:
The Modified Gap Excess Ratio (GER*) and the Stratigraphic Congruence of Dinosaur Phylogenieshttp://sysbio.oxfordjournals.org/cgi/content-nw/full/57/6/891/
The GER values for the actual dinosaur groups are "extremely high".
and so on
No problem with the fossil record there.
But when it comes to Paraves the value is .5579 (which the authors call "indistinguishable from random".)
The problem is not with the fossil record. The problem is with the dino-to-bird idea.
