I won't assume that I am the major proponent of use of Segnosauria over
Therizinosauria, but I come pretty darn close -- however, Mike Keesey is
right in saying that as supra-familial taxonomy, and well as lacking in
phylogenetic definitions that can be compared to each other, Segnosauria
is unknown in status or nature when compared to Therizinosauria.
Therizinosauria cannot be used in the ICZN's system, and issues of
priority of roughly useless.

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.
