Trail bikers find suspected tasmanian tiger skull

Two trail bike riders claim to have discovered what could be the skull of a tasmanian tiger while filming during a ride through bushland.

The skull is being scientifically evaluated this morning.

Brothers Levi and Jarom Triffitt are members of the Tassie Boys, a group of stunt trail bike riders based in central northern Tasmania.

They say they were riding in bushland last week while filming stunts for a promotional video when they came across the skull.

They say it is unlike anything they have ever seen before, and closely resembles the skull of a thylacine.

"Lot's of people think 'dog', but when you actually get on Google and compare it to your normal dogs that are in Tasmania, the closest thing we could find it to was an American timber wolf, which I don't believe we have here," Jarom said.

The last known tasmanian tiger died in the Hobart Zoo in 1936.

Levi denies the find is a hoax.

"We were just having a regular day - just doing some photography and filming," he said.

The brothers plan to have the skull checked in Launceston this morning.

Man's best friend for 30,000 years: Canine skulls discovered in two separate digs reveals historic relationship Read more: http://www.dailymail.co.uk/sciencetech/article-2091192/Dog-skull-Siberia-33-000-years-old--hints-mans-best-friend-didnt-come-single-ancestor.html#ixzz1kwlrxhlz

Dogs have been a loyal companion to mankind for more than 30,000 years, findings reveal.

Scientists believe that two 33,000-year-old skulls unearthed in digs in Siberia and Belgium show dogs were domesticated long before any other animal, such as sheep, cows or goats.

Researchers from the University of Arizona said the skulls had shorter snouts and wider jaws than undomesticated animals such as wolves, which use their longer snouts and narrower jaws to help them hunt.

The researchers think dogs could have been the first species of animals to be domesticated by humans, long before farm animals were bred for their meat and skins. 

This offers a possible explanation for why breeds such as pugs and huskies look so different, despite being the same species.

The scientists used carbon dating to determine the age of the two skulls, then looked at the bone structures and concluded that claims the dogs had been domesticated were ‘pretty solid’.

Study author Dr Greg Hodgins, whose findings were published in the journal PLoS ONE, said: ‘Both the Belgian find and the Siberian find are domesticated species based on morphological [structural] characteristics.

‘Essentially, wolves have long thin snouts and their teeth are not crowded, and domestication results in this shortening of the snout and widening of the jaws and crowding of the teeth.

‘The interesting thing is that typically we think of domestication as being cows, sheep and goats, things that produce food through meat or secondary agricultural products such as milk, cheese and wool and things like that.

‘Those are different relationships than humans may have with dogs. The dogs are not necessarily providing products or meat.

‘They are probably providing protection, companionship and perhaps helping on the hunt.

‘And it’s really interesting that this appears to have happened  first out of all human relationships with animals.’
