Skeletal reconstructions of a borhyaenid sparassodont (A, Borhyaena tuberata; modified from Sinclair [33]), hyaenodont “creodont” (B, Hyaenodon horridus; modified from Scott and Jepsen [34]), and canid carnivoran (C, Canis lupus, public domain from Wikimedia Commons), scaled to the same thorax length (not head-body length, due to differences in relative neck length in the three taxa), illustrating the proportionally larger heads of Borhyaena and Hyaenodon
