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)?


Regards,

 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.
