Thylacinus megiriani is a species of carnivorous marsupials lived during the late Miocene. 8 million years ago the area Thylacinus megiriani inhabited was covered in forest with a permanent supply of water.

Thylacinus megiriani was a quadrupedal marsupial predator, that in appearance looked similar to a dog with a long snout. Its molar teeth were specialized for carnivory, the cups and crest were reduced or elongated to give the molars a cutting blade and in proportion with its body its teeth were exceptionally large, possibly adding to its body weight. Its estimated weight is over 57 kilograms.

It is thought that Thylacinus megiriani, along with crocodiles and giant monitor lizards were the only predators in Alcoota.

Thylacinus megiriani fossils along with Thylacinus potens have been discovered in Alcoota in the northern territory, although the remains of Thylacinus in Alcoota are very rare. Paleontologist have found specimens densely packed together that died within a matter of years of one another. It is theorized that drought and unpredictable weather were the cause.
