Toretocnemus is an extinct genus of ichthyosaur. Its remains have been found in California, U.S.A.,[1] in Triassic layers of the Carnian Hosselkus Limestone.
Toretocnemus was named in 1902 by John Campbell Merriam.[2] The generic name is derived from Greek toretos, "perforated" and kneme, "shinbone". The type species is Toretocnemus californicus. Its holotype is UCMP 8100, a skeleton lacking the skull. Merriamia zitteli (Merriam 1903) Boulenger 1904, previously Leptocherius zitteli,[3] was renamed Toretocnemus zitteli in 1999. Its holotype is UCMP 8099, a skull, lower jaws and front of the torso.
Toretocnemus is about two metres long.
