Excalibosaurus (meaning "Excalibur's lizard") is a monotypic genus of marine prehistoric reptiles (ichthyosaurs) that lived during the Sinemurian stage (approximately 199.5 ± 0.3 Ma to 192.9 ± 0.3 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-quarters the length of the upper jaw, giving the animal a swordfish-like look. The only known species is Excalibosaurus costini.
