Erythrotherium
Erythrotherium (meaning "red beast") is an extinct genus of basal mammaliaforms from the Late Triassic to Lower Jurassic. It is related to Morganucodon. Only one species is recorded, Erythrotherium parringtoni, from Red Beds, Stormberg Group, Mafeteng, Upper Elliot and Clarens Formations, 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. References
