What is plantigrade locomotion?
Plantigrade locomotion is the way some animals walk with their toes and metatarsals (heels) flat on the ground.
Terrestrial (land) mammals have three ways of walking:
(1) digitigrade (walking on their toes with their heels permanently raised),
(2) unguligrade (walking on the nail of their toes – the hoof – with the heel permanently raised), and
(3) plantigrade (walking with their toes and heels on the ground).
The leg of a plantigrade mammal includes the bones of the upper leg, called the femur and humerus, and the bones of the lower leg, called the metatarsals and metacarpals.

The Tasmanian Tiger (Thylacinus cynocephalus) is an extinct Australian marsupial mammal. It was also called Tasmanian Wolf. It was not a tiger, nor a wolf, nor a dog (canid).
