Yes, this paper redescribes and photographs, for the first time, the
holotypic and paratypic material to *Alectrosaurus* as originally referred
by C.W. Gilmore in 1933. The holotype is restricted to a partial hindlimb,
and the forelimb material was referred, and includes four caudals that all
apply to a therizinosauroid. This material also includes claws, and the
humerus, as the archives may illustrate, is remarkably slender and
delicate in comparison to other segnosaurs (i.e., all therizinosauroids,
*Beipiaosaurus*, their most recent common ancestor, etc.). *Alectrosaurus*
is known now from a more complete postcrania and cranial material,
descriubed by Perle in 1979, but I have not seen this paper as yet and
Mader and Bradley discuss only the material Gilmore had available to him.

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
