RE: Late Triassic prosauropods from Madagascar and Texas

Also, has there been any further work on the Madagascaran "prosauropods"?
They don't appear to be prosauropods, or even dinosaurs. There may be
something more recent than this, but this is what Goswami et al. (2005) had
"Recently, terrestrial sediments of ?Isalo II? (of the Isalo Group) from the
southern Morondava Basin of Madagascar (Besairie, 1936) have yielded a
diverse mid-late Triassic fauna, including the island's first traversodontid
cynodonts (Flynn et al., 1999, 2000) and potentially the oldest known
prosauropod (Flynn et al., 1999). The latter was tentatively identified
based on synapomorphies of the dentary and maxillae shared with Prosauropoda
(Flynn et al., 1999), although preparation of additional cranial and
postcranial material likely pertaining to this taxon suggests that it may
represent a more basal archosaur (thus, to reflect this uncertainty, we
conservatively refer to this archosaur taxon as ?prosauropod? in quotation
marks throughout this paper)."
