Sarcosaurus diagram of known material: reconstruction based on basal Ceratosaurs (such as Berberosaurus and Saltriovenator). The Skull was made to look more generic and less like more derived Ceratosaurs such as Ceratosaurus. "Liassaurus", referred to "cf. Sarcosaurus woodi" and is smaller than the holotype: material in light grey is preserved, but to what extent is uncertain as it is not figured. References: Carrano and Sampson (2004).
