Erythrotherium
Erythrotherium is an extinct genus of basal mammal from the Late Triassic to Lower Jurassic. It is related to Morganucodon. Only one species is recorded, Erythrotherium parringtoni, from Red Beds, Stromberg Group, Mafeteng and Upper Elliot Formation and Clarens Formation, from Lesotho and South Africa.
The single jaw of 'Erythrotherium' was found in the matrix surrounding a dinosaur fossil, by the person preparing the dinosaur, Mr C. Gow.
