. Subsequent discoveries of bones dating from 20,000 years ago to less than 600 years old reveal it was found only in the west and northwest of the South Island, in Northwest Nelson and Buller. Scarlett's shearwater was closely related to the fluttering shearwater ( ''P. gavia'') and Hutton's shearwater ( ''P. huttoni''), and DNA evidence from fossil bones show that all three had a common ancestor about 1 million years ago.Tennyson, A.J.D.; Shepherd, L.D.

It was smaller than its relatives, with an estimated weight of 250 g, and had the short wings characteristic of the fluttering shearwater.
