Story summary

Giant kangaroos weighing up to 250 kg likely could hop, supported by strong Achilles tendons and leg bones.
The study, led by Dr. Megan Jones of the University of Manchester, analyzed fossils to reach this conclusion.
Contrary to earlier theories that thicker tendons would hinder hopping, the researchers argue that it is unlikely.
The researchers propose that giant kangaroos hopped less frequently and over shorter distances, highlighting their extinction.
