Australia Post previously depicted _Timimus_ as an ornithomimosaur in
its 1993 stamp series on Aussie dinosaurs.  As the Australia Post
website says _Timimus_ "is now interpreted as a member of a quite
different group".  This would be the Tyrannosauroidea, following
Benson et al. (2012; doi:10.1371/journal.pone.0037122) who
re-interpreted _Timimus_ as a smallish but fairly advanced
tyrannosauroid; and further suggested that an isolated tyrannosauroid
pubis (NMVP186046), also from the Early Cretaceous of SE Australia,
might belong to _Timimus_.  The fairly derived position within the
Tyrannosauroidea inferred for both the _Timimus_ holotype femur and
the pubis (Benson et al. (2010; doi 10.1126/science.1187456) fits with
the reconstruction of _Timimus_ with a tyrannosaurid-type skull (mouth
open, of course) and short didactyl forelimbs.


The 2013 reconstruction of _Timimus_ also updates the 1993
reconstruction in another important respect: _Timimus_ has feathers.
Well done Australia Post!
