  • B. elegans (B. yuannanese)[2]

Bienotherium was a therapsid from the Early Jurassic of China.[2] Despite its size, it is closely related to Lufengia, and is the largest tritylodont from the Lufeng Formation in China.[3]

Bienotherium had four incisors, no canines, and back molar-like teeth, which it used to chew tough plant material.[4]


Bienotherium is defined as being big and robust compared to other tritylodonts, and also by exposed maxillaries in the skull, an unusually long diastema and thin zygomatic bone.[3]
