More of my dinosaur speculations can be seen in my DA "Paleo & Sci Illo" gallery:[link]
I've gone out on a limb on this one. There is no concensus among planetologists as to the antiquity of Saturn's ring system. It is highly unlikely that the ring system we see today would have been present 65 million years ago. The ring patterns could change dramatically over the span of millions of years. They may even be ephemeral. There may have been epochs in which Saturn had no rings at all and they had to be replenished as additional moons fell below the planet's Rosche limit and became grist for the mill. There is even less certainty about the age of the ice geysers at Enceledus' south pole. This phenomenon too is linked to the small moon's position relative to Saturn in terms of Saturnian radii. The only hint to the stability of the Saturnian moon system is the apparent geological cycle of the neighboring moon Titan.
I have depicted a group of Troonauts enjoying the two hundred kilometer high geysers on the Solar System's smoothest and brightest moon in terms of albedo.
