Leptonectes is a genus of ichthyosaur that lived in the Late Triassic to Early Jurassic (Rhaetian - Pliensbachian). Fossils have been found in Belgium, Germany, Spain and the United Kingdom.^[3]^[4]^[5] A possible specimen from Switzerland first reported in 2006,^[6] has been reclassified as that of Hauffiopteryx.^[7] The type species, L. tenuirostris, reached 4 metres (13 ft) long, while L. moorei reached 3 metres (9.8 ft) long; the largest species, L. solei, was approximately 5–6 metres (16–20 ft) long.^[8]^[9]
