A thylacine was reportedly shot and photographed at Mawbanna in 1938. A 1957 sighting from a helicopter could not be confirmed on the ground. An animal killed in Sandy Cape at night in 1961 was tentatively identified as a thylacine. The results of subsequent searches indicated a strong possibility of the survival of the species in Tasmania into the 1960s. Searches by Dr. Eric Guiler and David Fleay in the northwest of Tasmania found footprints and scats that may have belonged to the animal, heard vocalisations matching the description of those of the thylacine, and collected anecdotal evidence from people reported to have sighted the animal.
