It is generally agreed that this carnivorous (meat eating) marsupial is extinct, though occasionally there is local unconfirmed sightings in its "former" wild habitat of Tasmania.
The thylacine is the shape and size of a big dog (especially like a dog in forequarters and head) , and observation suggestion that it acted in a very dog like manner (ie running, sitting, sun baking, etc)
The stripes started 1/2 way down the back and extended to the tail,
and were believed to be for camouflage (eg in sunny + shady forests)
The base colour of the animal was brownish (fawn through to dark brown) with a cream coloured belly
One very unique aspect was that its jaw could open extremely wide.
Its tail was very straight more like a thin Kangaroos tail and did not wag like a dogs
The female has a backward facing pouch, and extraordinary the male also has a pouch, his though to protect his testicles
LOCATION & HABITAT
Originally thought to roam all over the mainland of Australia, it was confined to the island of Tasmania for the last 3,000 years. There has been no confirmed sighting in the wild since 1932
The Thylacine was found in open forest and scrubland close to its grazing prey of wallabies etc and close to the protection of forests. They were a nocturnal creature sleeping by day in the safety of dense vegetation
The reason the Thylacine (Tasmanian Tiger) became extinct is many fold
Below is some of the reasons
*) The arrival of Native aborigines with their dogs
*) The arrival of the dingo from mainland Australia,
is thought to be the main reason for the Thylacines demise.
The dingo hunted for the same food as the Thylacine,
but was a lot more efficient and adaptable.
*) The arrival of European settlers
..............-) The loss of habitat due to farming and grazing
..............-) Protection of their sheep etc
..............-) Bounty hunters reaping Government payment for dead "Tigers"
The last thylacine to be shot in the wild was in 1932 and the last to die in captivity was in 1936.
They were nocturnal hunters (especially at dusk), hunting other marsupials (Wallabies and smaller animals + sheep) at night by smell using its pace and stamina to run down smaller animals until they became tired.
It would use its wide opening jaws to rip out its preys neck and feed only once from the fresh kill.
(it seems Thylacine only liked fresh meat)
They were solitary hunters it seems
The Thylacines it seemed bred once a year, with the young being carried in their mothers backward facing pouch, which had 4 teats.
After approximately 6-8 months the young now too big for the pouch were left alone in a sheltered place whilst their mother went for food.
