AbstractThe present study included identification and systematic description of some ammonites from the upper part of Chia Gara Formation, on the southern limb of Maten anticline at Amadia area, northern Iraq. Six species belong to five genera and three families were described. The two species; Berriasella privasensis and Parodontoceras calistoides were previously identified, and four species were left under open nomenclature, due to bad preservation and lack of material, these are; Parodontoceras sp., Spiticeras (Kilianiceras) sp., Substeueroceras sp. and Haploceras sp.
The studied ammonites occur as an assemblage fauna in the Durangites Zone, which indicates Late Tithonian age for the upper part of Chia Gara Formation in the Amadia area..
