Or a sauropodomorph (Langer, 2004)....
If this is Langer's chapter in the new Dinosauria volume, then my impression
is that he was a little more circumspect in his assessment of the _Aliwalia_
femur. The femur does show one or two sauropodomorph-like characters; then
again, it also shows other features in common with non-sauropodomorphs.
Langer concluded that the femur was probably dinosaurian, but couldn't stick
his neck out beyond that.
Interestingly, the _Aliwalia_ femur was found associated with sauropodomorph
material, and was originally referred to _Euskelosaurus_. As was the
maxilla, I think - which belongs to a carnivore, but perhaps not to
_Aliwalia_. Over to Adam Yates...
Langer's chapter is quite interesting, given that, among other things, he
revives the idea that _Spondylosoma_ might be a dinosaur (or at least
include dinosaurian material) from the Ladinian. He also disputes the
sauropodomorph affinities of _Guaibasaurus_, and instead aligns it with the
Theropoda. Under Padian and May's definition, it would be a theropod.
