The worong or crescent nailtail wallaby was a very common marsupial of south western Australia. It lived in various types of vegetation and acted similar to a rabbit. When disturbed they would retreat into logs where they were easily captured. In one survey in 1907 collected 18 specimens. Around 1908, the population of crescent nailtail wallabies plummeted. No one knows exactly what caused the steep decline in their population. There were many factors such as clearing land for sheep grazing and farms. The crescent nailtail wallabies also had to compete against invasive species like the "gray blanket" aka the escalated rabbit population. The introduction of the red fox in the 1870's for recreational hunting and feral cats also took their toll on this small marsupial. The last living worong was caught in a dingo trap on the Nullarbor Plain in 1927 or 1928. Mr. Mills sent it to Taronga Zoo. It is thought that the last crescent nailtail wallaby died in the more isolated arid areas of its range around 1956. As of 2019, 100 species, including the crescent nailtail wallaby, have gone extinct since the arrival of Europeans to Australia. Could the crescent nailtail wallaby live in Australia today? Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The worong could be a good candidate. Scientists would have many specimens that were collected in the early 1900's during population surveys. Australia has made many strides in restoring natural habitats, eliminating invasive species, and helping struggling species recover. If the worong was brought to life, could it ever be reintroduced to its native homeland in Australia?
