RE: new paper and new sauropod genus

new genus: Isisaurus Wilson & Upchurch 2003

Occurrence: Lameta Formation (Maastrichtian), India

Incidentally, the genus _Isisaurus_ made an appearance in the description of _Rajasaurus_ earlier this year (Wilson and Seeno, 2003). I would guess that the name is derived from the Indian Statistical Institute (ISI) of Calcutta.



SYNOPSIS Titanosaurs represent approximately one-third of sauropod diversity
and were geographically widespread throughout the Cretaceous, especially on
southern continents.

Is there any evidence of any sauropods apart from titanosaurs surviving into the last few million years of the Cretaceous? Apart from the poorly known _Campylodoniscus_ (which might be a titanosaur), all Campanian-Maastrichtian sauropods appear to belong to the Titanosauria, including the nemegtosaurids, _Antarctosaurus_ (chimera?) and _Opisthocoelicaudia_.
