Kourisodon was a small, fast-swimming marine lizard that lived in the late Cretaceous seas. It had sharp, blade-like teeth for slicing through fish and other prey. Even though it was a mosasaur, not a dinosaur, it was a fierce predator in its ocean home.1

1

Kourisodon was a small mosasaur, only about 3.75 metres (12.3 feet) long, much smaller than giants like Mosasaurus.1

2

Its name means 'razor tooth' in Greek, because its teeth were shaped like blades.1

3

Fossils of Kourisodon have been found in both Canada and Japan, showing it lived in the Pacific Ocean.12

4

The first Kourisodon fossil was discovered along the Puntledge River on Vancouver Island, and the species was named K. puntledgensis after that river.1

5

A life-sized replica of the Puntledge River specimen is on display at the Canadian Fossil Discovery Centre in Morden, Manitoba.1

6

Kourisodon lived alongside long-necked plesiosaurs (elasmosaurids), turtles, and other mosasaurs, but no short-necked plesiosaurs (polycotylids) were found in its Canadian home.1

Kourisodon was named in 2002 by paleontologists Elizabeth Nicholls and Dirk Meckert, based on a fossil found on Vancouver Island, Canada. The type species is K. puntledgensis.13
ገና ዘከራኽር
Scientists are not sure if the Japanese fossils belong to a second, unnamed species of Kourisodon, because they have slightly different teeth.1
