Kangaroos’ giant ancestor probably able to hop despite 250kg weight, scientists say

Research for first time suggests tendon and bones in heavier species would have made bounding possible

Kangaroos’ giant ancestor probably able to hop despite 250kg weight, scientists say

TL;DR

  • Giant kangaroos, weighing up to 250kg, may have been capable of hopping.
  • Researchers studied fossils of sthenurine, Protemnodon, and giant Macropus species.
  • Analysis of the fourth metatarsal bone and achilles tendon strength indicated suitability for hopping.
  • Hopping might have been used infrequently or over shorter distances, possibly at slower speeds.
  • The study provides a potential understanding of the biology and ecology of extinct giant kangaroos.
