  We can coin a name like Mononyches (or Mononykes to agree with the 
convention), but I would tend away from this as it trods on the recommendation 
that names referring to features of anatomy should be applied to 
apomorphy-based definitions. Such a definition would make its content identical 
to what is known of Alvarezsauria
