Tasmanian Tigah No Extinct Yet? ๐ฏ๐
Get plenny peopo who tink da Tasmanian tigah, o’ “thylacine,” stay extinct fo’ long time awready, but get oddahs who tink dey jus stay hiding real good. ๐ฒ Da new research wen go look at hundredz of reports from ova one century, showing dat da thylacine might still be around fo’ couple more decades in da most remote places of Tasmania. ๐๏ธ
“Get some small pockets wea da species coulda still stay,” said Barry Brook, one professor of environmental sustainability at da University of Tasmania. ๐ฟ
One big problem wit da thylacine an’ extinction in general is dat it’s hard fo’ prove someting stay gone fo’ real. ๐ฆ Like da Australia’s night parrot, dat everybody thought was extinct fo’ 140 years, but den dey wen find ‘um again.
Da las’ known thylacine wen stay at da Hobart Zoo in Tasmania in 1931, and wen mahke in 1936. European settlers, some of ‘um stay scared dat da animal going attack dea livestock, wen hunt da striped, meat-eating marsupials, dat look mo’ like wolves den cats. ๐บ Da Tasmanian government even wen give kala fo’ each thylacine dey catch. By da early 1900s, da population wen go down choke, Dr. Brook said.
But aftah da animal stay assumed fo’ be extinct in Tasmania, get cryptozoologists, hikers, an’ even hunters o’ park rangers who wen see da thylacine fo’ decades. Dat wen make peopo wonda if da thylacine still stay around. ๐ฎ
Dr. Brook an’ his colleagues wen use one statistical approach fo’ undahstand wen an’ wea da thylacine wen go extinct. Dey wen look at 1,237 Tasmanian tigah reports from 1910 an’ on, an’ rate ‘um fo’ how much dey can trust ‘um. ๐
Da study wen find dat da mo’ solid reports wen come from da time befo’ 1930s. Aftah dat, da numba of peopo who wen see o’ trap thylacines an’ knew wat dey stay looking at wen go down. But had one park officer who wen see one in 1982, an’ Dr. Brook’s model show dat dea’s one small chance da tigah wen survive ’til da 1980s o’ even da early 2000s. โณ
But even tho’ dea’s one small chance da thylacine stay alive today, da odds dat dey still around get mo’ an’ mo’ smalla. Da scientists agree dat da chances fo’ find one living thylacine stay unlikely. ๐
Dr. Brook said, “Da hope fo’ some peopo is dat da thylacine goin’ be one Lazarus species dat goin’ rise from its tomb an’ walk again, but dat no happen yet.” ๐

Tasmanian Tiger: Extinct or Expert Hider? ๐ฏ๐ฟ
Some people believe the Tasmanian tiger, also known as the thylacine, has been extinct for nearly a century, while others think it’s just been great at staying hidden. New research examining hundreds of reports spanning over a century suggests that there’s a good chance the thylacine may have survived for a few more decades in the most remote parts of Tasmania. ๐๏ธ
Barry Brook, a professor of environmental sustainability at the University of Tasmania, said, “There are pockets where the species could have maintained small populations.” One of the problems with the thylacine, and extinction in general, is that it’s difficult to prove that something is truly gone. The night parrot in Australia was thought to be extinct for 140 years until its recent rediscovery. ๐ฆ๐
The last known thylacine was given to Hobart Zoo in Tasmania in 1931 and died in captivity in 1936. European settlers, who mostly harbored unwarranted fears that the animal would attack livestock, relentlessly hunted the striped, carnivorous marsupials, which resembled wolves more than felines. The Tasmanian government even offered bounties on the thylacines. By the early 1900s, the population had crashed, according to Dr. Brook. ๐บ๐ซ
Cryptozoologists, hikers, and even the occasional hunter or park ranger have reported thylacine sightings for decades after the animal’s presumed extinction in Tasmania. This has driven speculation about whether 1936 marked the final death of the species or if it managed to hang on. Dr. Brook and his colleagues decided to take a statistical approach, combining all the reports they could gather and rating them in terms of reliability to improve their understanding of when and where the thylacine might have gone extinct. ๐๐
In a study published last month in the journal Science of the Total Environment, Dr. Brook’s team studied 1,237 Tasmanian tiger reports from 1910 onward. They classified these reports in terms of credibility. More than half of the reports came from the general public. The team also found spikes of sightings that were probably linked to high-profile thylacine news in Australia โ what Dr. Brook’s team called “recency bias.” ๐ฐ๐
Some reports between 1910 and 1937 were of confirmed captures or kills, with the last fully wild photographed kill occurring in 1930. Dr. Brook’s team considered another four reports of kills and captures/releases from 1933-37 legitimate. For the following eight decades, 26 deaths and 16 captures were reported but not verified, as were 271 reports made by people that Dr. Brook’s team considered experts: former trappers, outdoorsmen, scientists, or officials. These types of high-quality reports from experts peaked in the 1930s and started to fall in the 1940s. ๐ฒ๐
People who had definitely trapped or seen thylacines before the 1930s, and who presumably knew what they were looking at, had either died or retired by the 1970s. “That whole pool of expertise kind of dries up by the 1970s,” Dr. Brook said. The best quality report after that, he said, came from a park officer who saw one in 1982. A model based on all these reports reveals Tasmanian tigers likely went extinct between the 1940s and 1970s, with a smaller chance they persisted in remote areas until the 1980s.
