Excalibosaurus is known from only two skeletons. The first was found in 1984 on a beach in Somerset, England.1

Its lower jaw was only about three-quarters the length of its upper jaw. This gave it a swordfish-like appearance.1

The larger specimen had a skull 1.54 metres (5 feet 1 inch) long and a total body length of 6.528 metres (21.42 feet).1

Excalibosaurus belongs to a group of ichthyosaurs called Leptonectidae. Its closest relatives are Leptonectes and Eurhinosaurus.1

The name Excalibosaurus comes from the legendary sword Excalibur, because of its long, blade-like upper jaw.1

Excalibosaurus lived during the Sinemurian stage of the Early Jurassic, between about 199.5 and 192.9 million years ago.1 2

The second and more complete skeleton was bought by the Royal Ontario Museum in Canada.1
