"The big men" Torvosaurus gurneyi (170mm) - Natural History Society, Torres Vedras - Portugal
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 Rauhut in 2003 and to a very basal position in the Tetanurae by Thomas Holtz in 1994; all these assignments are not supported by present phylogenetic analysis. In 1985, Jensen assigned Torvosaurus a family of its own, the Torvosauridae. Despite support for this concept by Paul Sereno and Mateus, it seems redundant as Torvosaurus is closely related to, and perhaps the sister species of, the earlier Megalosaurus within a Megalosaurinae. However, Torvosauridae may be used as an alternative name for Megalosauridae if Megalosaurus is considered an indeterminable nomen dubium. Though a close relative of Megalosaurus, Torvosaurus is seemingly more advanced or apomorphic. Torvosaurus's larger clade, the Megalosauridae, is most commonly held as a basal branch of the Tetanurae, and considered less derived than carnosaurs or coelurosaurs, and likely related to the spinosaurids.
