How do we know what a Tasmanian tiger look like?

The Tasmanian tiger, or thylacine, is known primarily through historical accounts, photographs, and preserved specimens. Descriptions from early settlers and scientists, along with various illustrations, provide insight into its physical features, such as its striped back, elongated snout, and dog-like appearance. Additionally, taxidermied specimens in museums help researchers understand its anatomy and coloration. Despite its extinction in the 20th century, these sources collectively give us a detailed picture of what the Tasmanian tiger looked like.
