[1] Sangusaurus fossils have been recovered from the upper parts of the Ntawere Formation in Zambia and of the Lifua Member of the Manda Beds in Tanzania.

[3] The first Sangusaurus fossil was found in 1963 during a joint paleontological expedition of the British Museum (Natural History) and the University of London.

The presence of slickenplanes and carbonate nodules in the deposit are indicative of a highly seasonal distribution of rainfall and/or fluctuating water table height.

[1] Differences setting Sangusaurus apart include the presence of a low boss behind the pineal foramen and the posterodorsally directed intertemporal bar, which is narrower than in other stahleckeriids.

In all stahleckeriids for which femoral material has been recovered, including Sangusaurus, the head is distinctly separate from the dorsal edge of the greater trochanter.

[11] Kenneth D. Angielczyk, P. John Hancox & Ali Nabavizadeh (2018)[3] provided the first in-depth study of the masticatory system of Sangusaurus.

In sum, the feeding system of Sangusaurus consisted “of a primarily orthal power stroke of the oral cavity, with slight palinal motion in tandem, followed by transverse motion of the dentary aided by a lateral pulling vector of the dorsolaterally oriented mAMEL [M. adductor mandibulae externus lateralis].” The authors concluded that Sangusaurus may have developed a novel means to exploit altered vegetation after the end-Permian mass extinction.
