Thylacine footprints could be distinguished from other native or introduced animals; unlike foxes, cats, dogs, wombats or Tasmanian devils, thylacines had a very. South Sudan's rhino population 'wiped out' by civil war. New Footprint Suggestions. How about introducing a ? I think, many would use that, as many profile texts say . What I love about planetromeo is the contacting in two steps.

First you give a footprint and when something comes back, you start texting. Footprints are not as binding as texting someone. What guys without profile pics (or just body pics or pics of random stuff like animals, landscapes, etc.) also use footprints to start communication that may lead to step two. It would be great if one could communicate via footprint, that one starts the communication only when it’s face to face. It’s not as harsh as texting . The one without pics loves to start a discussion on that issue and on superficiality. Having startet texting he already has his foot in the door and goes on your nerves. The Icon could be someone with a paper bag on his head and a red cross on it : -). Thylacine - Wikipedia. Thylacine. 1. 90. Scientific classification. Kingdom: Animalia. Phylum: Chordata. Clade: Synapsida. Class: Mammalia. Infraclass: Marsupialia. Order: Dasyuromorphia. Family. It is commonly known as the Tasmanian tiger (because of its striped lower back) or the Tasmanian wolf. It was the last extant member of its family, Thylacinidae; specimens of other members of the family have been found in the fossil record dating back to the late Oligocene. Surviving evidence suggests that it was a relatively shy, nocturnal creature with the general appearance of a medium- to- large- size dog, except for its stiff tail and abdominal pouch (reminiscent of a kangaroo) and dark transverse stripes that radiated from the top of its back, similar to those of a tiger. The thylacine was an apex predator, like the tigers and wolves of the Northern Hemisphere from which it obtained two of its common names. As a marsupial, it was not closely related to these placental mammals, but because of convergent evolution it displayed the same general form and adaptations. Its closest living relative is thought to be either the Tasmanian devil or the numbat. The thylacine was one of only two marsupials to have a pouch in both sexes (the other being the water opossum). The male thylacine had a pouch that acted as a protective sheath, covering his external reproductive organs while he ran through thick brush. The thylacine has been described as a formidable predator because of its ability to survive and hunt prey in extremely sparsely populated areas. Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributing factors may have been disease, the introduction of dogs, and human encroachment into its habitat. Despite its official classification as extinct, sightings are still reported, though none has been conclusively proven. Evolution. The skulls of the thylacine (left) and the timber wolf, Canis lupus, are quite similar, although the species are only distantly related. Studies show the skull shape of the red fox, Vulpes vulpes, is even closer to that of the thylacine. Species of the family Thylacinidae date back to the beginning of the Miocene; since the early 1. Riversleigh, part of Lawn Hill National Park in northwest Queensland. This thylacinid was much smaller than its more recent relatives. Since the thylacine filled the same ecological niche in Australia as the dog family did elsewhere, it developed many of the same features. Despite this, it is unrelated to any of the Northern Hemisphere predators. Zoology students at Oxford had to identify 1. Word soon got around that, if ever a 'dog' skull was given, it was safe to identify it as Thylacinus on the grounds that anything as obvious as a dog skull had to be a catch. Then one year the examiners, to their credit, double bluffed and put in a real dog skull. The easiest way to tell the difference is by the two prominent holes in the palate bone, which are characteristic of marsupials generally. Discovery and taxonomy. Thylacine rock art at Ubirr. Numerous examples of thylacine engravings and rock art have been found dating back to at least 1. BC. By the time the first European explorers arrived, the animal was already extinct in mainland Australia and rare in Tasmania. Europeans may have encountered it as far back as 1. Abel Tasman first arrived in Tasmania. His shore party reported seeing the footprints of . The first definitive encounter was by French explorers on 1. May 1. 79. 2, as noted by the naturalist Jacques Labillardi. In 1. 80. 5 William Paterson, the Lieutenant Governor of Tasmania, sent a detailed description for publication in the Sydney Gazette. Recognition that the Australian marsupials were fundamentally different from the known mammal genera led to the establishment of the modern classification scheme, and in 1. Geoffroy Saint- Hilaire created the genus Dasyurus where he placed the thylacine in 1. To resolve the mixture of Greek and Latin nomenclature, the species name was altered to cynocephalus. In 1. 82. 4, it was separated out into its own genus, Thylacinus, by Temminck. This is the earliest known non- indigenous illustration of a thylacine. Several studies support the thylacine as being a basal member of the Dasyuromorphia and the Tasmanian devil as its closest living relative. Research published in Genome Research in January 2. The resulting cladogram follows below. Many European settlers drew direct comparisons with the hyena, because of its unusual stance and general demeanour. The stripes were more pronounced in younger specimens, fading as the animal got older. Its body hair was dense and soft, up to 1. Its rounded, erect ears were about 8 cm (3. Two other films are known, shot in London Zoo. The female thylacine had a pouch with four teats, but unlike many other marsupials, the pouch opened to the rear of its body. Males had a scrotal pouch, unique amongst the Australian marsupials. The jaws were muscular but weak and had 4. Their claws were non- retractable. The cast shows the planter pad in more detail and shows that the planter pad is tri- lobal in that it exhibits three distinctive lobes. It is a single planter pad divided by three deep grooves. The distinctive planter pad shape along with the asymmetrical nature of the foot makes it quite different from animals such as dogs or foxes. This cast dates back to the early 1. Museum of Victoria's thylacine collection. It is likely to have relied on sight and sound when hunting instead. It is possible that the thylacine, like its relative, the Tasmanian devil, gave off an odour when agitated. It could also perform a bipedal hop, in a fashion similar to a kangaroo. The animal was also able to balance on its hind legs and stand upright for brief periods. During hunting it would emit a series of rapidly repeated guttural cough- like barks (described as . It also had a long whining cry, probably for identification at distance, and a low snuffling noise used for communication between family members. Adelaide Zoo, 1. 88. Little is known about the behaviour or habitat of the thylacine. A few observations were made of the animal in captivity, but only limited, anecdotal evidence exists of the animal's behaviour in the wild. Most observations were made during the day whereas the thylacine was naturally nocturnal. Those observations, made in the twentieth century, may have been atypical as they were of a species already under the stresses that would soon lead to its extinction. Some behavioural characteristics have been extrapolated from the behaviour of its close relative, the Tasmanian devil. Proof of the animal's existence in mainland Australia came from a desiccated carcass that was discovered in a cave in the Nullarbor Plain in Western Australia in 1. It tended to retreat to the hills and forest for shelter during the day and hunted in the open heath at night. Early observers noted that the animal was typically shy and secretive, with awareness of the presence of humans and generally avoiding contact, though it occasionally showed inquisitive traits. Early pouch young were hairless and blind, but they had their eyes open and were fully furred by the time they left the pouch. Its stomach was muscular, and could distend to allow the animal to eat large amounts of food at one time, probably an adaptation to compensate for long periods when hunting was unsuccessful and food scarce. Some studies conclude that the animal may have hunted in small family groups, with the main group herding prey in the general direction of an individual waiting in ambush. Prey is believed to have included kangaroos, wallabies and wombats, birds and small animals such as potoroos and possums. One prey animal may have been the once common Tasmanian emu. Animals usually take prey close to their own body size, but an adult thylacine of around 3. Researchers believe thylacines only ate small animals such as bandicoots and possums, putting them into direct competition with the Tasmanian devil and the tiger quoll. Such specialisation probably made the thylacine susceptible to small disturbances to the ecosystem. In fact, the predatory behaviour of the thylacine was probably closer to ambushing felids than to large pursuit canids. Consequently, at least in terms of the postcranial anatomy, the vernacular name of . Doubts exist over the impact of the dingo since the two species would not have been in direct competition with one another as the dingo hunts primarily during the day, whereas it is thought that the thylacine hunted mostly at night. In addition, the thylacine had a more powerful build, which would have given it an advantage in one- on- one encounters. The thylacine was also much less versatile in diet than the omnivorous dingo. The adoption of the dingo as a hunting companion by the indigenous peoples would have put the thylacine under increased pressure. This paper notes that Australia lost 9. The results show that the humans were obviously one of the major factors in the extinction of many species in Australia. But in reality, it was not until the humans had an adverse effect on the environment and brought disease to Australia that their arrival drove the thylacine to extinction. The results of their investigation indicated that the last of the thylacines in Australia, on top of the threats from dingoes, had limited genetic diversity, due to their complete geographic isolation from mainland Australia. The paper observed the obviously competitive relationship between the dingo and the thylacine and the Tasmanian devil, and noted that the dingo may have actually fed on the native hen. Yet, the paper concludes, people ignore the emergence of humans on the continent among all of this. In the end, the competitiveness of the dingo and thylacine populations led to the extinctions of the thylacine but the arrival of the humans only further exacerbated this.
