Inosaurus is poorly described and illustrated.  It's also one of those taxa
Lapparent described based on lots of unassociated remains found strewn
through the desert.  There were four vertebrae (sacral, caudals) that were
thought to be similar, three caudals previously illustrated by Stromer
(1934), and eighteen vertebrae (4 dorsals, 2 sacrals, caudals) associated
with a proximal tibia.  All of these are syntypes at present, and only
Stromer's material and two caudal vertebrae are illustrated.  Of these five
caudals, three lack neural arches and the other two have incompletely
preserved processes.  Even if we assume these all belong to the same taxon,
it is difficult to pin down its relationships.  Those illustrated by
Lapparent ( http://dino.lm.com/images/display.php?id=38 ) resemble
Yangchuanosaurus, Alxasaurus and Nomingia most closely.  The enlarged
chevron facets are only known in Nothronychus as far as I can determine.
The only diagnostic character noted in the description is that dorsal centra
show a "sharp keel between two deep depressions" on their ventral surface.
The caudal morphology prevents it from being a paravian, and perhaps the
shortened distal caudals indicate it was enigmosaurian or ceratosaurian.
It's all quite uncertain until someone redescribes them.

Jubbulpuria is supposed to be an indeterminate abelisaurid (Novas and
Bandyopadhyay, 1999).

Seems to be a basal averostran, related to Dilophosaurus and Zupaysaurus.
