Wakaleo oldfieldi

Wakaleo oldfieldi is an extinct species of Wakaleo found in the Cenozoic deposits of South Australia. It had three unfused molar teeth instead of two fused molars as is the case with the Thylacoleo carnifex.

As with T. carnifex, this species is presumed to have used its maxillary (upper) teeth to hold its food and sharpen the mandibular teeth, the latter were also used in slicing and stabbing during eating. The premolars also had a crescent-shaped circumference for slicing.
