Taniwhasaurus belongs to a group called tylosaurines, which had a long, toothless tip on their upper jaw like a bony spear.1
The first fossils of Taniwhasaurus were found in the 1860s at Haumuri Bluff in New Zealand, and named by James Hector in 1874.1
One species, Taniwhasaurus antarcticus, was originally named Lakumasaurus after a sea spirit from the mythology of the Yahgan people of South America.1
A nearly complete skull of Taniwhasaurus antarcticus was discovered on James Ross Island in Antarctica in 2000, measuring 72 centimeters (28 inches) long.1
Taniwhasaurus lived between about 86 and 66 million years ago, during the Late Cretaceous period.2
The species Taniwhasaurus oweni was named in honor of the famous paleontologist Richard Owen, who first described marine reptiles from New Zealand.1
Taniwhasaurus fossils have been found in marine rocks that were once part of ancient seabeds, alongside ammonites, sharks, and other mosasaurs.1
