Allosaurus, to be sure, is known from growth series.
I would seriously doubt this,
based on Allain's recent redescription of S. altdorfensis. The latter is
more similar to Eustreptospondylus (=Magnosaurus?) because it shows- paired
hypapophyses; no ventral keel on dorsal centra; dorsal centra much longer than
tall; poorly developed pubic boot; no posteromedial astragalar
process.

Sinraptor dongi, S.
hepingensis and Y. magnus should be in there too then, as Rauhut (2000)
found them so similar as to be potenetially synonymous. Of course, these
taxa are allosauroids (by definition), so unless megalosaurs end up next to
sinraptorids, I don't think your results will be held up.
