Aglyptorhynchus

Aglyptorhynchus is an extinct genus of marine billfish that was distributed worldwide from the early Eocene to the early Miocene. Fossils are primarily known from the Northern Hemisphere, but one species is also known to have inhabited the waters off New Zealand.
The following species are known:A. columbianus Fierstine, 2005 - Late Oligocene of Washington, US A. denticulatus - Early Miocene of Austria A. hakataramea Gottfried, Fordyce & Rust, 2012 - Late Oligocene of New Zealand A. maxillaris Fierstine, 2001 - Late Oligocene of Oregon, US A. sulcatus - Early Eocene of Belgium and England A. venablesi Casier, 1966 - Early Eocene of England and Virginia, US
Indeterminate remains are known from the early and late Oligocene of South Carolina and the Miocene of Hungary. It has been hypothesized that Aglyptorhynchus originally arose in the Atlantic around the warm Gulf Stream, and migrated to the Pacific by the Oligocene via the then-open Central American Seaway.
