Gengasaurus is an extinct genus of ophthalmosaurid ichthyosaur from the Jurassic. The type and only species, Gengasaurus nicosiai, was named in 2017, after the locality of Genga, Marche.[1] It lived in Italy about 152 million years ago.[2]

History

The near complete holotype was discovered in 1976 in the Late Jurassic (Tithonian) Calcari ad aptici e Saccocoma Formation at Camponocecchio and it was described in 1980[3] and 2000[4] as the "Genga ichthyosaur" before it was named and described in 2016[5][2] - this paper was eventually published in 2017.[1] The holotype is now housed at the Spaelaeo-Palaeontologic Museum in Genga.
