Lexovisaurus (which is named after the Lexovii, an ancient, savage tribe from western Europe) is one of those stegosaurs that hasn't quite been nailed down yet, classification-wise. It was originally assigned as a species of Dacentrurus, then reassigned to its own genus, though paleontologists have attributed some remains to the even more shaky Loricatosaurus. Whatever the case, Lexovisaurus appears to have been one of the earliest European stegosaurs, a medium-sized herbivore that browsed the low-lying vegetation of modern-day France and England.
