Saturn may have destroyed one of its moons to make its rings

"A catastrophic event could have created Saturn's rings while the dinosaurs were still roaming Earth."

Catastrophism in the solar system is apparently wide ranging now like Earth during Precambrian with bombardment taking place from 4.5 to 2.5 Gyr and sometimes even after the Precambrian. Include Venus too with young crater ages. Saturn is in the news routinely it seems concerning efforts to fit young age observations into the 4.56 Gyr solar system model.

How Old Are Saturn's Moons? Sky & Telescope 142(3):14-21, 2021. "Most things in the solar system are ancient: 4.57 billion years old, give or take a few million years. So it's unsurprising that astronomers thought the same of the Saturn system. But since the Voyagers passed by the giant planet in 1980 and 1981, astronomers have been debating that view." Some groups today argue that Saturn's rings are young, perhaps 100 million years old."

The Origin and Evolution of Saturn: A Post-Cassini Perspective,

My observation. While the paper argues for core accretion in the postulated primordial disc in the ecliptic for Saturn, it is clear various properties of Saturn does not fit with the 4.56 Gyr old solar system model. The rings could be <= 100 Myr and Titan rapid outward migration from Saturn is a surprise. There is the documented heat problem at Saturn and Jupiter too indicating they are much younger than 4.56 Gyr.
