Therocephalian specimens. a Skeleton of Glanosuchus (SAM-PK-K7809) showing the wolf-like proportions typical of some members of the group. b Left side of the skull and jaw of Mirotenthes (UCMP V3695/40467), a typical small therocephalian. c Left side of the skull of Euchambersia, a therocephalian thought to have been venomous (e.g., Kemp 2005). Note the very different skull proportions compared to Mirotenthes and the presence of pit on the side of the snout that may have housed a venom-secreting gland. Images not to scale
