I. Lost Not Forgotten

Field notes

The thylacine was a striped carnivorous marsupial, with a stiff tail and a pouch in which females carried their young. Once widespread across Australia and New Guinea, it survived longest in Tasmania, hunting mainly at night through a varied landscape.

Former range
Australia and New Guinea historically; last surviving population in Tasmania
Habitat
A mosaic of dry eucalypt forest, wetlands and grasslands

Extinction

Colonial persecution, including bounties, drove the Tasmanian decline alongside other pressures. The last known captive thylacine died in Hobart in 1936. Later reported sightings have not provided conclusive evidence that the species survives.
