# Fleming Fjord Formation

The Fleming Fjord Formation, alternatively called the Fleming Fjord Group is an Upper Triassic geological formation in the northeastern coast of Jameson Land, Greenland. It consists of terrestrial sediments and is known for its fossil content.

## Description

It is of Norian to Rhaetian age and is subdivided into three members; at the base the Edderfugledal Member, followed by the Malmros Klint Member with the Ørsted Dal Member at the top. It was deposited in a large shallow to ephemeral lake.

## Paleobiota

The fauna of Fleming Fjord is diverse, including sauropodomorph dinosaurs, pterosaurs, temnospondyls, mammaliaforms, aetosaurs, and other taxa. Freshwater unionid bivalves and conchostracans have been reported from the Malmros Klint Member.

### Fish

Lungfish, actinopterygian, and chondrichthyan teeth have been reported from the Malmros Klint Member.
