  Check out Sereno et al. (1994, 1996, 1998) and discussions of
Gondwanaland separation therein. Also, the _Encyclopedia of Dinosaurs_
covers the subject a little, if memory serves.

<I would also like to know if there are any Cretaceous formations

  The Santana F. is the best example, around Albian and/or Cenomanian
of age (late Early to early Late K). Again, the _Encyclopedia of
Dinosaurs_ and _the Complete Dinosaur_ have this info.
