RE: Dinos galore [snip] and Tendaguru dinos

I've been reading some of the new papers (I don't have them all yet), in particular, Currie et al.'s phylogeny paper. I don't like that it excludes ornithomimosaurs and maniraptorans since they are closer taxa to the tyrannosaurids than Allosaurus

Ahhh... but are they? I recall seeing at least one fairly recent phylogeny that found tyrannosaurs to be the next outgroup above carnosaurs. Perhaps it was an AMNH paper.

Yep. Pretty straight forward descriptive anatomical stuff: it was the paper in which the forelimb elements of _Alectrosaurus_ were shown to be from a segnosaur (therzinosauroid), rather than from _Alectrosaurus_ itself. (Once upon a time, _Alectrosaurus_ was famous for being a tyrannosaurid with
rather large arms...).

Hence, some older publications suggested that _Alectrosaurus_ might be closely related to the bona fide big-armed theropod _Chilantaisaurus_.

Also, _Elaphrosaurus bambergi_ is from Tendaguru as well.
