Loricatosaurus

Loricatosaurus (meaning "armored lizard") is a dinosaur of family Stegosauridae from Callovian-age (Middle Jurassic) rocks of England and France.
Discovery and naming.
"Loricatosaurus" is known from remains previously assigned to "Lexovisaurus". These remains were discovered at the Fletton brick pit in the Oxford Clay Formation, Fletton, Peterborough, England, by Alfred Leeds during November 1901. The material was later assigned to "Stegosaurus priscus" by Baron Franz Nopcsa in 1911. However, upon later review of the material in 2008, Susannah Maidment and colleagues determined that "Lexovisaurus" was based upon nondiagnostic remains, and coined a new genus for the other specimens. The species name, "priscus", comes from the oldest name associated with diagnostic specimens, Baron Franz Nopcsa's "Stegosaurus" "priscus" of 1911. It is known from only two partial skeletons. Contrary to previous reports (as "Lexovisaurus"), a shoulder spine is not present in the known material; the possible spine is more likely from the tail.
The genus name "Loricatosaurus" derives from the Latin "loricatus" (meaning armoured) and the Greek "sauros" (meaning lizard). The specific name derives from the Latin "priscus" (meaning ancient).
Description.
The holotype (BMNH R3167) is a partial skeleton, including two cervical, six dorsal, and 16 caudal vertebrae, a right humerus and right ulna, some carpus, two metacarpals (one incomplete), a partial ilia, partial right ischium, and pubis, the left femur, partial tibia and fibula, fused tarsals, and some armour plates. This material now resides in the British Museum of Natural History's palaeontology collection. Another referred specimen (MHBR 001), from an unnamed unit referred to as the Marnes a "Belemnopsis latesulcatus" Formation from the lower Callovian, Middle Jurassic of Le Fresne d’Argences, Calvados, Normandy, France, includes neck, back and tail vertebrae, a left upper arm, right thigh, shin and calf, and some armour plates.
Multiple phylogenetic analyses carried out by S. Maidment and O. Mateus between 2008 and 2010 place "Loricatosaurus" as a basal genus within the family Stegosauridae.
