It says it's for Newcrest but if you read more it also says: "This default also affects Willow Creek and the background houses in Oasis because EA has cloned the background houses in these three worlds BUT it won't affect the other worlds."
I don't know if this mod is broken, or up-to-date, etc, so use at your own risk. I believe it is to be combined with this mod: modthesims.info/download.php?t=568508 This mod will remove the props like the dinosaur from Oasis Springs. Again, Idk if it's up to date.
