Argonauta oweri is an extinct species of argonautid octopus.

[1][2][3] The type specimen, a fossilised eggcase, measures 118 mm in diameter.

[1] It was collected by John R. Ower of Superior Oil Company (after whom it is named) in a "limy concretionary boulder" in Hautapu River, due west of Flat Spur and 1.4 miles (2.3 km) southeast of Utiku, New Zealand.

[1] The fossil was not found in situ and therefore its parent formation is unknown,[3] though Hautapu River flows exclusively through early Pliocene rocks and according to the describing author "the horizon is almost certainly Waitotaran".
