Palvennia is an extinct genus of ophthalmosaurid ichthyosaurian known from the uppermost Jurassic of Central Spitsbergen, Norway.^[1] It was named for PalVenn, the Friends of the Palaeontological Museum in Oslo, whose expedition led to the discovery of the type specimen. Palvennia is known from a single skull from the Slottsmøya Member of the Agardhfjellet Formation (middle Volgian/late Tithonian, Late Jurassic). The skull is 860 mm long, but is unusual in having a very short rostrum (~0.6× the skull length), similar to Ichthyosaurus breviceps. Because of this, the orbit seems very large (0.34× the skull length), but this may be effected by crushing.^[1] The single and only known species is Palvennia hoybergeti Druckenmiller et al., 2012.
