Abstract

The most recent studies reformed the occurrence of Garagu Formation, Dohuk area,
Kurdistan Region, Northeastern Iraq. The present paleontological study, in the type
locality, aids the recognition of the formation. Recognizing fourty nine genera and
species of the; Benthonic and Planktonic Foraminifera, Ostracods, Calcareous Algae,
and Coral, with other fossils such as ; Gastropoda shell, Echinodermata spine,
Pelecypoda shell, Spone spicules and Brachiopds shell, which are described and figured.
The stratigraphic distribution and diversity of these fossils assemblages indicate the
Hauterivian-Barremian age of the Garagu Formation. The fossil assemblages in the
Garagu Formation are characteristic for a shallow marine setting with local transitions to
continental facies, shelf lagoonal environment and open platform.

Key Words:
Garagu Formation
Microfossils
Paleoenvironment
Dohuk
Kurdistan
Iraq
