Two taxidermied thylacine (Tasmanian tiger) heads, previously believed to be extremely rare, have been discovered in the United Kingdom within weeks of each other, profoundly changing their perceived rarity and auction value. The finds have been recognized as major scientific breakthroughs, altering the understanding of existing thylacine specimens and increasing the total known taxidermied heads worldwide to three.

These discoveries challenge previous assumptions about the scarcity of thylacine artifacts, offering new material for scientific study and re-shaping the market for natural history items. They also prompt questions about the potential existence of other undiscovered specimens of the extinct species.

What the records show

The first thylacine head, initially misidentified as a fox, was sold at an auction in Bristol on August 11, 2026. It had been listed as a “tatty fox head” with an estimated price of £40. British collector James Cranfield purchased the item for a hammer price of £50,000, with the total cost, including fees, reaching £60,000 or £62,600. Cranfield identified the specimen as a thylacine by noting its eight upper incisors, a distinct feature from a fox’s six. The vendor had originally acquired it for £50 at an antiques market.

Weeks after the news of this first sale gained international attention, a second thylacine head emerged. This specimen, affectionately named “Trevor” by staff, was brought forward by a London family who had stored it under a bed and came forward after seeing reports of the previous auction. Dr. Stephen Sleightholme authenticated “Trevor,” which has since been added to the International Thylacine Specimen Database as specimen UKH. “Trevor” is scheduled for auction on November 26, 2026, in Bath, and is estimated to sell for tens of thousands of pounds. Both discoveries were handled by Auctioneum Ltd.

What changed and for whom

Before these recent finds, only one taxidermied thylacine head was recorded globally, and its location was unknown. The discovery of the first head made it the second recorded example, and “Trevor” became the third. The re-evaluation of thylacine specimen rarity now impacts scientific understanding and the value of such artifacts for collectors and institutions.

What the subject has said publicly

Andrew Stowe, of Auctioneum, noted the extraordinary nature of these discoveries, stating that uncovering “two-thirds of all known thylacine heads is extraordinary”. He described the finds as “a major scientific breakthrough and a vital piece of history,” rather than merely rare items. Stowe also recounted that the second head’s owners “were reading the news and spotted the report of our previous example,” which prompted them to retrieve their own specimen. James Cranfield, upon acquiring the first head, initially hailed it as the “holy grail” of the natural history world and claimed it was “the only one in existence”.

What we could not confirm

The current whereabouts of the originally recorded taxidermy thylacine head remain unknown.
