number of teeth in the complete maxilla. The material from Germany is further distinguished by the other two species by a temporal difference of c. 10 Ma and a few morphological differences which indicate that the animal was the third species outside a sister taxon relationship between T. tanneri and T. gurneyi. The material is only 10% smaller than the maxilla of T. tanneri, although the ontogenetic stage of the specimen is unknown, indicating that derived megalosaurines were already among the largest terrestrial predators in the late Middle Jurassic, with only a moderate increase in size in the genus in the Late Jurassic. Torvosaurus had an elongated, narrow snout, with a kink in its profile just above the large nostrils. The frontmost snout bone, the premaxilla, bore three rather flat teeth oriented somewhat outwards with the front edge of the teeth crown overlapping the outer side of the rear edge of the preceding crown. The maxilla was tall and bore at least eleven rather long teeth. The antorbital fenestra was relatively short. The lacrimal bone had a distinctive lacrimal horn on top; its lower end was broad in side view. The eye socket was tall with a pointed lower end. The jugal was long and transversely thin. The lower front side of the quadrate bone was hollowed out by a tear-shaped depression, the contact surface with the quadratojugal. Both the neck vertebrae and the front dorsal vertebrae had relatively flexible ball-in-socket joints. The balls, on the front side of the vertebral centra, had a wide rim, a condition by Britt likened to a Derby hat. The tail base was stiffened in the vertical plane by high and in side view wide neural spines. The upper arm was robust; the lower arm robust but short. Whether the thumb claw was especially enlarged, is uncertain. In the pelvis, the ilium resembled that of Megalosaurus and had a tall, short, front blade and a longer pointed rear blade. The pelvis as a whole was massively built, with the bone skirts between the pubic bones and the ischia contacting each other and forming a vaulted closed underside. Systematics and classification When first described in 1979 by Galton and Jensen, Torvosaurus was classified as a megalosaurid, which is the current consensus. It was later assigned to Carnosauria by Ralph Molnar et al. in 1990, and to a basal position in Spinosauroidea by Oliver Walter Mischa
