  My comments on observation of the original, non-plastoholotypic material
of *Kakuru* can be found here:  http://qilong.8m.com/Kakuru.html. This
requires some minor revision, but essentially, unlike ceratosaurs,
*Kakuru* lacks a lateral ridge that partially overlaps the ascending
process of the astragalus, and has a largely subtriangular distal profile,
a feature of tetanurans and lacking in ceratosaurs, including abelisaurs.
The height and shape of the ascending process also defies that which is
known in *Masiakasaurus* or other basal abelisaurs for which this region
is known (very few, in fact) -- this page was written before the
description of *Masiakasaurus.*

  As for the other species, these have been covered to some extent in the
DML archives by the likes of Brian Choo, Mickey Mortimer, or myself. There
is more info forthcoming on the "Victorian" claw as well as other material
that has been around for a while, but this will have to wait for the
paper.

  Cheers,

  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.
