How fast could a thylacoleo run?

The thylacoleo, also known as the marsupial lion, is believed to have been relatively agile for its size, but specific speed estimates are difficult to ascertain due to its extinct status. Some research suggests it could run at speeds of around 20 to 30 kilometers per hour (12 to 18 miles per hour) over short distances, similar to modern large predators. However, its primary adaptations were likely more suited to climbing and ambush tactics rather than sustained running.
