In July 2019, Australian authorities on the island of Tasmania received a report of a footprint spotted by an unnamed individual on a walk up to Sleeping Beauty Mountain in the southeast of the state. “Wasn’t able to take a photo, however he googled it when he got home and believes it was a Tasmanian Tiger,” the report reads, according to the Tasmanian Department of Primary Industries, Parks, Water and Environment (DPIPWE). That same year, a government plant biologist saw what they believed to be a Tasmanian tiger (Thylacinus cynocephalus), or thylacine, from 30 meters (100 feet) away in a remote area. “Good description given, bounded into bush,” the report states. In 2018, three cyclists said they witnessed a thylacine crossing the road in front of them. Images captured in 1911 and 1933. From the public domain. These are just three of more than 1,200 alleged thylacine sightings reported between 1910 and 2019 in Tasmania that have been collated and analyzed by Barry Brook, a mammal ecologist at the University of Tasmania, and colleagues to create the Tasmanian Thylacine Sighting Records Database, which they used to estimate an extinction date for the thylacine. Their findings, released in pre-print format in January through bioRxiv and undergoing peer review, indicate the iconic Australian marsupial predator most likely died out in the late 1990s or early 2000s — decades later than has been assumed. The results surprised even Brook. “Contrary to expectations, the inferred extinction window is wide and relatively recent, spanning from the 1980s…This article was originally published on Mongabay Läs mer
