  • Kaiwhekea katiki Cruickshank & Fordyce, 2002 (type)

Kaiwhekea is an extinct genus of plesiosaur from the Late Cretaceous (Maastrichtian age) of what is now New Zealand. The type species, Kaiwhekea katiki, was first described by Arthur Cruickshank and Ewan Fordyce in 2002. Kaiwhekea was approximately 7 metres long and lived around 69-70 million years ago. The single known specimen, found in the Katiki Formation, is nearly complete, and is on display at the Otago Museum in Dunedin, New Zealand.[1]

Kaiwhekea has been placed as an aristonectid plesiosaur close to Aristonectes (O'Keefe and Street, 2009). In 2010, Kaiwhekea was transferred to Leptocleididae.[2]
