Lexovisaurus ("speech lizard") was one of the first dinosaurs from mid-to-Late Jurassic Europe, 165 mya to be discovered. It was a stegosaur. Its fossils (pieces of armor and limb bones) have been found in France and northern England.
Description
Lexovisaurus fighting off an allosaur
The French specimens show that Lexovisaurus was probably rather like Stegosaurus. Traditionally, this dinosaur was depicted as having either large spines over the hips or shoulders, with a selection of flat plates and round pointed spines that ran along the back and tail. Lexovisaurus was probably about 5 meters long. The type specimen, Lexovisaurus durobrivensis, was formalized by Hoffstetter in 1957. The specimen was originally placed in Omosaurus (now Dacentrurus) 70 years earlier. Recent work by Susannah Maidment and colleagues indicates that Lexovisaurus is based on undiagnostic remains, so these workers coined Loricatosaurus to hold other remains that had been assigned to Lexovisaurus.
