Nobody has convinced me, despite a wealth of cladograms, that segnosaurs were
theropods, let alone "very late Spinosaurs," and I continue to find loads of
niggling errata about the presence or absence of certain characters in such
venerable studies as Clark et al. After grinding out a bunch of cladograms,
it would be good to stand back a little and examine their evolutionary
implications, see whether there were any functional reasons for the
character-state changes, that sort of thing. Computers can generate
unbelievable volumes of cladograms, but >at most one< can be correct.
