Geologic formation in Chubut Province, Argentina
The Koluel Kaike Formation is a geological formation in Chubut Province , Argentina which spans around 50 to 47.1 million years ago from the Early to Middle Eocene .It predominantly consists of pyroclastic deposits[ 1] semi-arid environment.[ 2] [ 1] South American native ungulates (notoungulates , litopterns , astrapotheres ) as well as armadillos , and caviomorph rodents .[ 3]
The Sarmiento Formation overlies the Casamayor Formation and forms the most recent sequence of the stratigraphic section. The formation is named for the town of Sarmiento
