Anotations

Scope note:

Fossil resin found in Romania. Similar to succinite, but it has been held to be of different botanical origin. Recent studies suggest that differences instead indicate that ruminite is a succinite that has suffered partial thermal degradation during the folding of the Oligocene Kliwa sandstone formation in which it is found.
