"The big men" Torvosaurus gurneyi (170mm) - Natural History Society, Torres Vedras - Portugal

T. sp. in Japan

When first described in 1979 by Galton and Jensen,[2] Torvosaurus was classified as a megalosaurid, which is the current consensus.[10] It was later assigned to Carnosauria by Ralph Molnar et al. in 1990,[16] and to a basal position in Spinosauroidea by Oliver Walter Mischa Rauhut in 2003[17] and to a very basal position in the Tetanurae by Thomas Holtz in 1994;[18] all these assignments are not supported by present phylogenetic analysis.[10] In 1985, Jensen assigned Torvosaurus a family of its own, the Torvosauridae.[8] Despite support for this concept by Paul Sereno[19] and Mateus,[14] it seems redundant as Torvosaurus is closely related to, and perhaps the sister species of, the earlier Megalosaurus within a Megalosaurinae.[10] However, Torvosauridae may be used as an alternative name for Megalosauridae if Megalosaurus is considered an indeterminable nomen dubium.[20] Though a close relative of MegalosaurusTorvosaurus 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.[10]

The following is a cladogram based on the phylogenetic analysis conducted by Carrano, Benson & Sampson (2012), showing the relationships of Torvosaurus:[10]
