[Rampart craters](https://en.wikipedia.org/wiki/Rampart_crater) are impact craters with fluidized ejecta. These are mostly found on Mars, and there is one on Earth (Ries crater). Have rampart craters been found on any other Solar System bodies? Perhaps on a moon of Jupiter or Saturn?

There are some rampart craters [on Earth](https://pubs.geoscienceworld.org/books/book/2312/chapter/130244719/Rampart-craters-on-Earth):

* Ries crater in Germany,
* Bosumtwi crater in Ghana,
* Tenoumer crater in Mauritania,
* Lonar crater in India, and
* Meteor crater in the United States

Additionally, a number of rampart craters have been discovered [on Ganymede](http://www2.ess.ucla.edu/%7Ejewitt/class/Surfaces_Papers/Boyce_10.pdf) and Europa.

[Ceres](https://solarsystem.nasa.gov/news/505/side-by-side-earth-vs-dwarf-planet-ceres/) **does not** have rampart crater, but it has craters, such as Haulani, that have flow features in their ejecta blankets.
