But I am VERY certain it lived well past the 1930s. However, persecution by humans would have made co-operative hunting very difficult, and likely lead to an increase of solo hunters favouring small-sized prey. Today controversy surrounds the thylacine and its potential as a candidate for ‘de-extinction’. Apr 29, 2019 - Australia accounts for one-third of all contemporary mammal extinctions worldwide. The last living Thylacine was Benjamin in the Hobart zoo in Australia in 1936.
