  Most likely not; Matley specified that the scutes, including a lump that
was specified as a partial braincase by someone and now which I mistakenly
(it appears) inferred as part of the type based on a paper I cannot find
and would choose to retratc until such I time I may be able to back it up,
a sacrum, and paired ilia that were almost certainly conjoined, with an
extremely robust tibia as the type. Chakravarti, in his review of
*Lametasaurus*, showed how *Lametasaurus* was a carnosaur, in his useage,
and specified that, based on assumptions then that the scutes of
association were undiagnostic but resembled in relative size the material
known for *Ceratosaurus* as well as that which were described for
*Dynamosaurus* (= *Tyranoosaurus*). Based on these works, it is likely
that the scutes in any case would not be considered diagnostic enough to
form a type, and Walker appears to be citing someone else; the remainder
of the original type appears to coincide with a single animal, were found
virtually side-by-side, and would then form an adequate type. As for the
specific history, few others have offered to study *Lametasaurus* since
Matley's initial description, von Huene and Matley's brief review (as an
ornithischian similar to *Omosaurus* {= *Lexovisaurus*}), and
Chakravarti's review that seems to have competantly shown it to be
theropodan.

<No, because the type braincase of Indosuchus lacks the central horn found
in "Rajasaurus" and Majungatholus.  Unless the horn is a sexually
dimorphic character or something.>

  Waiting for the paper, but so does the new indian form lack this as
well, possessing only a distinct parietal which appears to expand dorsally
rostrally, to "support" a median expansion; this is lacking in
*Majungatholus*. We will need to wait for the papaer for more, if its
sufficiently discussed to review. Then we get to wait for the description
of *Majungatholus* ...

  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.
