Hi!
Like I said, For all I know those 35 minutes were NOT produced. About 8 minutes were cut from the movie. Many of the deleted scenes included scenes which Steven Spielberg and George Lucas considered to scary for kids. Other of the outcut scenes showed Littlefoot's early discovery of the Great Valley (right after the quarrel with Cera). If those 35 minutes were really planned we can only speculate what they would have included. I read that the original idea was to emphasize the issue of racism among the different kinds of dinosaurs more than it was done in the movie as we know it. So I think it's quite likely that the Oasis-szene I quoted frequently might have been part of these 35 minutes.
