What trace fossils provide undeniable proof of Thylacoleo's bone-crushing capability?

Damage found on the calcaneus (heel bone) of a Macropus species.

The interpretation of Thylacoleo's bite strength is strongly corroborated by direct physical evidence left on fossilized prey remains, known as trace fossils. Specifically, evidence points to damage on the calcaneus, or heel bone, belonging to a Macropus species, which includes large kangaroos and wallabies. The nature of this damage was not merely a slice or a superficial tear; the fossil record shows clear evidence that the bone was crushed or deeply indented. This level of material failure requires forces far exceeding what is necessary just to process muscle and skin, directly supporting the biomechanical models suggesting the animal routinely fractured dense skeletal structures.
