Crossvallia is an

extinct genus of penguins. It includes two species, C. unienwillia and ?C. waiparensis. Their anatomy suggests that the genus is closely related to the Anthropornithinae.[1]

Taxonomy

Order

Sphenisciformes

C. unienwillia was the first of the genus to be described, whose remains were recovered from and named after the

Late Paleocene Cross Valley Formation on Seymour Island, Antarctica.[2] It measured about 140 cm (4.6 ft).[1]

In August 2019, a new species of Crossvallia, C. waiparensis, was described based on leg bone fossils from

palaeontologist Leigh Love.[6]
