Wahlisaurus was a dolphin-like marine reptile that swam in the seas of Early Jurassic England. It had a very long, slender snout and an overbite, like a swordfish. It was not a dinosaur, but a type of ichthyosaur.1 2

Utuntu dushimishije

Wahlisaurus had a very unusual shoulder bone called a coracoid, which had a large hole in it. This hole is rarely seen in ichthyosaurs.2

The first Wahlisaurus fossil was discovered by a man named Percy Faulkes, who donated it to a museum when he died in 1951.1

Wahlisaurus is named after two scientists: William Wahl and Judy Massare, who both studied ancient marine reptiles.1

Only two specimens of Wahlisaurus have ever been found. The second one was discovered in 1996 but not identified until 2018.1

Wahlisaurus lived during the Hettangian age, about 201 to 199 million years ago, right after a big extinction event.3

Its snout was extremely slender and delicate, and its lower jaw was shorter than its upper jaw, giving it an overbite.2

Ishusho ya Wahlisaurus yakozwe na AI — Ishusho yakozwe na AI yerekana uko Wahlisaurus ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.
