Scelidosaurus partially sea-dwelling. Owen had not indicated a holotype. In 1888, Richard Lydekker while cataloguing the BMNH fossils, designated some of the hindlimb fragments described in 1861, specimen BMNH 39496 consisting of a lower part of a femur and an upper part of the tibia and fibula, together forming a knee joint, as the type specimen, hereby implicitly choosing them as the lectotype of "Scelidosaurus". Lydekker gave no reason for this choice; perhaps he was motivated by their larger size. Unfortunately, mixed in with the "Scelidosaurus" fossils had been the partial remains of a theropod dinosaur and the femur and tibia
Fibrous joint joint, form the only non-sutured joints in the skull. Most sutures are named for the bones they articulate, but some have special names of their own. A syndesmosis is a slightly movable fibrous joint in which bones such as the tibia and fibula are joined together by connective tissue. Examples include the distal tibia fibular joint as well as the radioulnar joint. Injuries to the ankle syndesmosis are commonly known as a "high ankle sprain". Although the syndesmosis is a joint, in the literature the term syndesmotic injury is used to describe injury of the syndesmotic ligaments. It comes from
