I've been arguing for years that the cladists have been misled by their
analyses into thinking that segnosaurs are theropods: They need just too many
reversals of certain features to bring segnosaurs into Theropoda. And, oddly,
all these reversals carry the reversed features back into Prosauropoda.
Simply go back into the archives of this list, for example, and look for some
of my earlier posts.
