RE: New Deinocheirus specimens found, indicating basal ornithomimosaur
Important point, and not an unexpected result given their relative phylogenetic
position (advanced therizino vs basal ?ornithomimo). According to the current
hypothesis, Deinocheirus is not that far apart from the sister of the ancestral
therizinosaur. Now, how does Deinocheirus compare to a *basal* therizinosaur,
eg Falcarius (good hypodigm)?

Something we need to consider is if
the attachment scars and crests are disproportionately big,
or simply the product of allometry
on a standard-model ornithomimosaur humerus. Comparison of
the humeri of Therizinosaurus and Deinocheirus show that the
former is
the real powerhouse of the two.
