K. puntledgensis Nicholls and Meckert, 2002 (type) Kourisodon (from the Greek κουρίς kourís + ὀδών odon, "razor tooth") is an extinct genus of mosasaur.

Fossils have been found from Vancouver Island in British Columbia, Canada,[1] as well as from the Izumi Group of Japan.

[3] Kourisodon puntledgensis is known from a single locality located in the Santonian Pender Formation along the banks of the Puntledge River (after which it was named).

[1] In 2005, a fragmentary skeleton from exposures of the Izumi Group on Shikoku Island, Japan, was assigned to Kourisodon sp.

[2] A 12' 3" complete replica of the Puntledge River specimen is on display at the Canadian Fossil Discovery Centre in Morden, Manitoba.
