California Thylacine?

The story of a man named Bill Warren, who claims to have purchased the pelt of a thylacine at a garage sale, has caught the eye of TBRC Chairman Alton Higgins. Read Alton's thoughts on this story below:

California Thylacine?

Alton Higgins, 20 November 2010

One ostensibly extinct animal that I'm very interested in is the Tasmanian tiger, or thylacine (Thylacinus cynocephalus), an apex marsupial predator (Figure 1). As indicated by the name, the species lived on the island of Tasmania, but it was also found on the Australian mainland, although it appears that the species was approaching extinction on the continent prior to European settlement. Personally, I think a few still survive in the most remote reaches of Tasmania.

Recently a story came out about a guy, Bill Warren, who says he bought a thylacine pelt for $5 at a California yard sale. If true, it could be a very valuable remnant artifact of a tragically persecuted species (Figure 2).

When I first saw the pictures of the find I was pretty excited, but the more I looked at the skin the more I wondered if it was something else. The folks at the Centre for Fortean Zoology and others suggested that the hide should be compared to that of a zebra duiker (Cephalophus zebra), a small (9-20 kg) antelope living in the dense forests of west Africa and one of the world’s most distinctively colored mammals (Figure 3).

I attempted to match a museum zebra duiker skin to a photograph of a live zebra duiker to see how well they compared in terms of the striping patterns (Figure 4). Based on the color of the museum skin, it looks like it has undergone some foxing, but the stripes aligned closely, as would be expected. The primary possible difference is that the museum skin appears to have an extra stripe in the shoulder area.

The mystery skin was also compared with the photograph of a live zebra duiker (Figure 5).

Finally, the mystery skin is shown side by side with the museum skin (Figure 6).

Figure 6. The mystery skin compared to a zebra duiker skin (right side of image).

In each of these comparisons, in my opinion, the putative thylacine skin appeared to correlate closely with the zebra duiker museum skin and the photograph of a living zebra duiker, lending credence to suggestions that the skin in question is not that of a thylacine.

A few years ago I was involved with trying to determine if the Emmerich photos taken in Tasmania were those of a thylacine. As part of that effort I examined patterns of thylacine stripes and observed that the initial position of stripes along the spine were very consistent, at least among the individual thylacine photographs available on the Internet (Figure 7). In attempts to perform a similar comparison, I was not able to achieve a satisfactory match between the mystery skin stripes and those available for examination in known thylacine photos.

Based on stripe pattern comparisons alone, I’d have to posit that the skin purchased by Bill Warren is probably that of a zebra duiker rather than a thylacine. Another factor to consider is that of the tendency of thylacine stripes to stay bold across the rump and onto the tail, as opposed to the characteristic of zebra duiker stripes to become less prominent towards the tail. While skin from the tail area of the mystery skin is missing, if it is indeed that of a thylacine, what is present matches the expected pattern of the zebra duiker.

The zebra duiker is classified as a threatened species. I’m sure any number of natural history museums would be happy to have it in their collection. If the skin is indeed that of a thylacine, interest will be even greater. Hopefully Mr. Warren will allow definitive testing to be conducted on the pelt. If nothing else, this whole episode has demonstrated that “cryptids” of various stripes can indeed pop up in unexpected places.

    You are so right. This is indeed the pelt of the Zebra duiker from Sierre Leone. The striking similarity to the thylacine pelt has previuosly lead many astray.
    Regarding the Emmerichs photos: Having been closely connected with the author of these prints for some years now, there is no doubting that the animal in the two photographs is a thylacine, the main issue at stake here being whether it is a genuine on location photograph or a simulated image. I tend to believe it is a genuine photograph, as having copies in my possession I am in a postition to carefully examine the print.

  2. Col. Bailey,

    Are the photographs available to view anywhere online? I would enjoy taking a look at them.


  3. I am bill warren and i have written reports from various experts on the tasmanian tiger and they agree my skin is a Tasmanian Tiger. The stripes on my skin are shorter than a duiker. My skin is much longer. Myh skin is soft when you run your hand against the grain.

  4. Mr. Warren,

    Thanks for emailing.

    I certainly hope it is the skin of a thylacine. I think everyone is rooting for that to be the case. Have you submitted any samples of the skin for definitive DNA testing? Have any museums come forward to help you get this done?


  5. Sorry Bill, your "experts" are wrong. It is a zebra duiker. I've been collecting mammal skins for 40 years or more, and feel 100% confident. It's still a rare pelt. You can always have DNA testing done to silence doubters such as myself.

  6. Black panther lived in Texas Louisiana and Florida back in the 1800s and is why they have the Florida Jaguars team. The US government put a bounty on them because they attacked rail road workers. They got money for the pelts. Texas had bears also. But I seen a black panther one night and thought it was a my black cow dog a blue healer. These dogs got tall legs. So this was a big cat 4 feet away. And I spot lighted it 4 feet away and it roared like a mountain lion and ran off so fast I couldn't keep my light on it. But it was walking up to me and my friend. And it was solid black and probably over 100lbs. I just remember it's eyes were a different color than my dogs. I think it was hunting us, sneaking up behind us. We were walking in a heavily wooded area with creeks. Then I researched the animals and they have a 50 miles range they travel as territory. So this is why they are hard to see. They don't stay in the same place for too long. They can travel over 10 miles in a day. They don't make a nest like most animals. They are always on the move hunting in this 50 mile area. There are also national forest 10 miles from where I seen this cat. So they got plenty of wooded area in East Texas to hide.
