Modified Madsen illustrations
Occiput of Allosaurus (MOR 693). Kindly sent to me by Eric Snively, modified from Multibody dynamics model of head and neck function in Allosaurus, Snively, Cotton, Ridgely, Witmer; Palaeontologica Electronica. This is the only image I could source of the skull viewed from behind. Although distorted during fossilization it is an important view omitted from Madsen 1976 .
Plan views of the braincase modified from Anatomy and Kenesis of the Allosaurus Skull, B.K. McClellend, Masters Thesis, 1990. Based on one subadult individual (UUVP 5961), it is one of the finest and least distorted dinosaur braincases yet discovered and the first to be described for Allosaurus.
