    Occasionally, it is suggested that the thylacine is not actually extinct on the Australian mainland.  This is often met with a certain amount of scepticism, as many members of the scientific community firmly believe that Tasmania is the only place where the species has existed within historical times.  However, folklore regarding the "Wild dog" and "Tiger" is to be found throughout the continent's rural areas.  These stories are likely reinforced by sightings, under unusual lighting conditions, of feral dogs which bear aberrant patterns of colouration or mange.  "Tiger" reports have come from northern Queensland for decades.  The subject of the "Queensland Tiger" has been reviewed in detail by Troughton (1967) and Heuvelmans (1962), with additional data provided by Anon (1969), and Makeig (1970).  These reports will not be covered further here, since virtually all of them describe the animal as being "cat-like", i.e. having a short face as opposed to an elongated one.  The footprint (from Cardwell) described by Scott (1872) differs from that of any known species of Australian predator.

    In January of 1973 however, the press reported two sightings of a striped, dog-like animal in the Longland Gap region of the Atherton Tableland (Anon. 1973a,b).  Dr. J. Winter made inquiries about the creature, bringing the number of reported sightings up to four, all falling between December 1972, and mid-January 1973.  No more than one mile separated the furthest sightings.  The descriptions given of the animal were detailed and unvarying, and fitted the thylacine quite well.  One of the sightings occurred early in the morning, which suggests that the stripes seen were not merely the result of dimmed lighting.

A selection of stills from a short piece of motion film footage taken in South Australia in 1973.  Could the animal shown here running across a road possibly be a thylacine?  When examined closely, the film is indeed intriguing.  However, one must not quickly jump to conclusions regarding rather blurry, nondescript images such as these.  It is believed by some that the animal is simply a fox which has lost much of the fur on its tail, perhaps due to mange.  Still, this may possibly be one of the strongest pieces of physical evidence yet produced to suggest that the thylacine exists on the Australian mainland.  The complete film sequence can be viewed here.

    In South Australia in 1973, Liz and Gary Doyle briefly captured a rather fascinating image on motion film.  It shows a yellow brown, dog-shaped animal running in a manner which appears to be suggestive of the thylacine.  Opinions on the true identity of the animal vary.  Some feel that it is merely a European fox (a species which was introduced to Australia by settlers during colonial times and has now become naturalized) which has lost much of the fur on its tail either due to mange or molting.  Others suggest that it may be a dog.  Despite performing a comprehensive analysis of the film frame-by-frame, I myself remain unable to form any solid opinion of it as of yet.  The image quality is simply too poor, and the motion too unsteady, to perceive any distinguishing physical features that would conclusively identify the animal as a thylacine.  However, the manner in which the animal runs is indeed quite interesting, and in several frames, stripes appear to be vaguely visible on the hindquarters.

    In a personal e-mail communication on 5 October 2005, the author of the online publication "Magnificent Survivor - Continued Existence of the Tasmanian Tiger", comments: 

    "The physical dimensions of the animal shown in the Doyles' footage are not consistent with a fox or dog - particularly the back legs, which look identical to those of the thylacine.  The animal also appears to be bigger than a fox, and the tail seems to be longer and certainly straighter than that of a fox or dog.  When running, most of the animal's driving force comes from the back legs, and some of the stills show it in a stance like that of a kangaroo.  It is fairly simple to identify a hoaxed thylacine image, but I can't see anything in this film to suggest it is a hoax.  The footage seems convincing to me - consistent with the running juvenile thylacine I saw in 2002, and there was no uncertainty in that case.  The juvenile that I witnessed also ran primarily using the power of the back legs, and appeared to grab and pull at the ground with its front feet."
