Life restoration

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, whereas L. moorei (NHMUK PV R 14370) likely reached 3 metres (9.8 ft) long ^[8] ; the largest species, L. solei, was approximately 5–6 metres (16–20 ft) long. ^{[9] [10]}
