Katiki Formation
The Katiki Formation is a Late Cretaceous geologic formation of the South Island of New Zealand. Plesiosaur remains of Kaiwhekea katiki, named after the formation, are among the fossils that have been recovered from the deltaic siltstones.Description
The Katiki Formation was defined by McKay in 1887 and comprises about of gently north to northeast dipping and generally massive, dark grey, indurated, sandy siltstones. The Katiki Formation overlies more proximal marine sandstones of the Herbert Formation and, below that, non-marine quartzose sandy to pebbly coal measures of the Shag Point Group.
