With all due respect, you might like to actually get hold of and read the 
paper. There happen to be reasons for our conclusion that it is probably 
not a therizinosauroid/segnosaur.

Mr Pickering's argument that fragmentary or incomplete specimens are 
taxonomically worthless and may as well be ignored is most amusing: 
please do keep us abreast of your latest incisive thoughts Mr Pickering, 
they are most valuable and no doubt have a profound affect on the 
palaeontological community.
