Baddeck in Nova Scotia sits on Windsor Group rocks deposited during this geological period, while thousands of kilometres away Belkovsky Island in the East Siberian Sea consists of tightly folded strata from its lower stage overlying Upper Devonian layers. Which coal-forming period, running roughly 359 to 299 million years ago, connects them geologically?

Question

Accepted Answer

Carboniferous. The Carboniferous Period, from about 359 to 299 million years ago, was named for the coal-rich strata across northwest Europe. It takes in the Mississippian and Pennsylvanian sub-periods, and its dense tropical swamps produced the coal seams that would eventually power the Industrial Revolution.
