Fakte argëtuese
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.12
The second and more complete skeleton was bought by the Royal Ontario Museum in Canada.1
