Battery Point Formation


The Battery Point Formation is a geologic formation in Quebec. It preserves fossils dating back to the early Emsian to early Eifelian the lower Devonian period.

Description

A part of the Gaspe [Bay Sandstone Group|Gaspé Sandstones], the Battery Point Formation is believed to have been deposited in a fluvial environment based on the presence of rootlets as well as the abundance of trough and planar-tabular cross bedding, and the lower part resembles modern braided systems more than meandering systems. It rests unconformably on the shallow marine sandstones of the York [River Formation], transitioning upwards into the Malbaie Formation, and is 2,300 meters thick.

Fossil content

Limited intervals in the lower part of the formation contain remains of a few brachiopods and bivalves, though marine fauna is not known from other parts of the formation. Plant and freshwater fish fossils are also known, with a large diversity of primitive vascular plants found within the formation.
