[1] It was found on a slope with strata that hosted a tetrapod fossil assemblage to the lower Tropidostoma AZ by a local sheep herder who then hung it on a fence on his farm.

[1] Other Late Permian therapsids have been collected from the same interval and vicinity including dicynodonts (Pristerodon mackay, Tropidostoma dubium, Diictodon feliceps), a gorgonopsian, and a pareiasaur.

[5] The cause of this end-Permian mass extinction is hypothesized to be climate change induced by volcanic CO2 degassing[6] which lead to a cascade of biotic response.

[7] Compared to their pelycosaur ancestors, Leucocephalus and other early therapsids are distinguished by more vertical (mammal like) leg positioning beneath their bodies, larger temporal fenestra and increased jaw complexity and power.

[2] Like other burnetiids, Leucocephalus skulls exhibit numerous distinguished bony protuberances and bosses giving it a bumpy appearance.

Leucocephalus also has a more random arrangement of polygonal raised surfaces and irregular trenches on maxilla than what is observed in other burnetiamorphs.
