The thylacine looked like a large dog, with stripes, according to the Tasmania Parks and Wildlife Service. Fully grown it measured about 180 cm (6ft) from nose to tail tip, stood about 58 cm (2ft) high at the shoulder and weighed up to 30kg.
The arrival of European settlers marked the start of a tragic period of conflict that led to the thylacine’s extinction. In 1936, the world’s last captive thylacine died in Hobart Zoo and in 1986 the creature was declared officially extinct.
But in 2008, Dr Andrew Pask from the University of Melbourne revealed how he had extracted DNA from a preserved thylacine and injected it into mouse embryos, which grew normally, triggering hopes that the animal could be restored.
