I may have defined Segnosauria as the stem-based clade way back in Mesozoic 
Meanderings #2, only I had it as the sister group to Brontosauria in 
Sauropodomorpha. That was when I considered segnosaurs to be 
"prosauropod-derived." No big deal; we still don't know what it's the sister 
group of in Theropoda (maybe Oviraptorosauria). Definitions come and go with 
each new cladification; difficult to take any of them seriously.
