Excalibosaurus

Excalibosaurus (meaning "Excalibur's lizard") is a monotypic genus of marine prehistoric reptiles (ichthyosaurs) that lived during the Sinemurian stage (approximately 196.5 ± 2 Ma to 189.6 ± 1.5 Ma (million years ago)) of the Early Jurassic period in what is now England. It is characterized by the extreme elongation of the rostrum, with the lower jaw about three-fourths of the length of the upper jaw, giving the animal a swordfish-like look. The only known species is Excalibosaurus costini.
