It's interesting you should mention the "larger noasaurs", because the very
large _Deltadromeus_ (which has been regarded as a noasaur) might also have
been somewhat "weird" - although this would be a different kind of "weirdness"
It all depends on how similar _Deltadromeus_'s skull and teeth were to smaller
noasaurs like the highly specialized _Masiakasaurus_. Based on the shape and
orientation of the anterior dentary teeth, _Masiakasaurus_ has been suggested
to have fed on small tetrapods, fish, or even invertebates. We'll need to find
more material for _Deltadromeus_ (including good cranial material) before we
can make assessments of its possible dietary habits. But until then, I don't
think we can assume that _Deltadromeus_ habitually attacked large prey.
