Research output: Contribution to journalArticlepeer-review


The remains of fossilized coraitalean trees were discovered in the middle of the 20th century in surface and underground mines in south-central Iowa, in the vicinity of the town of Knoxville. With some uncertainty, the source coal is assigned to the Laddsdale coal beds, which are early Desmoniensian, equivalent to early Asturian and middle Moscovian age.
