(Woodburne, 1967)

Thylacinus potens ("powerful pouched dog") was the largest species of the family Thylacinidae, originally known from a single poorly preserved fossil discovered by Michael O. Woodburne in 1967 in a Late Miocene locality near Alice Springs, Northern Territory. It preceded the most recent species of thylacine by 4–6 million years,[1] and was 5% bigger,[2] was more robust and had a shorter, broader skull. Its size is estimated to be similar to that of a grey wolf; the head and body together were around 5 feet long, and its teeth were less adapted for shearing compared to those of the now-extinct thylacine.[1]

More specimens were described in 2014.[3]
