==Phylogeny==
Hello everyone,

I recently completed a research paper regarding the thylacine. I believe It would be beneficial to include more information on the phylogeny of this marsupial. The following is an exert from my project:

"When determining the phylogeny of the thylacine, the evidence, brought forward, supported that the thylacine be placed into its own family- Thylacinidae. The reason for its classification, was based upon its dental and pedal morphology which did not resemble other Australian marsupials (Krajewski et al. 1992). Some argued that the species was closely related to extinct marsupial lineages from South America. However, it was eventually determined that the resemblances, between the two groups, were due to convergent evolution and that evidence supported that the thylacine should be placed under the Australian family Dasyuridae. A later study of basicranial morphology, eventually concluded that the thylacine shared no derived features of either the South American marsupials or the dasyuroids (Krajewski et al. 1992). It was determined that thylacines possessed features that were considered primitive for marsupials based upon DNA analysis of cytochrome b (ex: heart structure) (Krajewski et al. 1992). Further research, conducted on the basal ganglia of the thylacine and Tasmanian devil (the thylacine’s closest relative), showed a more modularized pattern in the cortex of the thylacine while the cortex of the Tasmanian devil was dominated by the putamen (Berns and Ashwell 2017)."

This is simply food for thought. I found the references and information interesting. Who would ever figure that such a species would spark such a complex debate as to where this animal should be placed on the phylogenetic tree. I would suggest reading the articles I referenced for more detail.

Edit suggestion

This text:

"per head. (Current value today, after inflation and introduction of decimal currency: $132.29) for"

should be changed to read

"per head (the equivalent of £100 or more today) for"

This page explains why "$132.29" is far more precise than it ought to be.

Thanks, Apokryltaros. There's still a stray period in there, though. 71.197.166.72 (talk) 23:42, 16 June 2016 (UTC)

David Fleay said the last Thylacine was a male

Should it be noted that David Fleay (the man who filmed and photographed the last captive Thylacine) said that the last individual was a male?

http://www.naturalworlds.org/thylacine/additional/benjamin/Benjamin_2.htm — Preceding unsigned comment added by Internetnicknamehere (talkcontribs) 10:54, 26 June 2012 (UTC)

The gender of Benjamin is reported inconsistently. Para 1 of "Benjamin and searches" states "Darby also appears to be the source for the claim that the last thylacine was a male; photographic evidence suggests it was female.[77]" Yet in the next para we read: "In 2011, detailed examination of a single frame from the motion film footage confirmed that the thylacine was male." This is inconsistent and should be corrected, whichever is correct (both are sourced).

New video

‘Extinct’ Tasmanian Tiger caught on camera? (VIDEO) - RT.com - 17 September 2016 The Cube Root Of Infinity (talk) 11:52, 18 September 2016 (UTC)

The hind feet (from heel to toes) look way too long in comparison. Probably just a dog. Anyway, "with its “prehistoric looking head” catching the woman’s attention." So before 1936 is prehistory now?FunkMonk (talk) 20:26, 18 September 2016 (UTC)
The hind feet are "dog," yet the gait is in no way dog. More like the "gamboling" of a calf or lamb: up-down-up-down. It never trots like a canid does.--75.164.145.192 (talk) 05:11, 26 October 2016 (UTC)
If the hind feet are those of a dog, it is not a thylacine. Gaits can be affected by a million things. The proportions of limbs not. FunkMonk (talk) 07:44, 26 October 2016 (UTC)

Another notable movie + game

Grammar error?

The last sentence of the 3rd paragraph says "Despite its official classification as extinct, sightings are still reported, though none has been conclusively proven." I believe this is a grammar error, and that the sentence should read as follows:

Despite its official classification as extinct, sightings are still reported, though none have been conclusively proven.

The sightings have not been proven, rather than the sightings has not been proven. Can anybody confirm/correct this?

2600:E000:54:139:9AEE:CBFF:FE03:5E93 (talk) 06:41, 5 March 2016 (UTC)

'None' means 'not one'. Therefore the singular is correct. Akld guy (talk) 05:31, 25 January 2017 (UTC)

No longer extinct

The species status needs to be changed. The Thylacine is no longer considered extinct. They have been found. Someone should edit the page. Please edit this. This information is very important. And people need to know. -A.E.M. 2/2/2017[1] — Preceding unsigned comment added by 2604:6000:78C3:3200:E02D:4561:B6CF:84E (talk) 23:29, 2 February 2017 (UTC)

The researchers are investigating proof of existence - the study itself is not proof that the species is not extinct.
"A team of investigators from the Centre for Fortean Zoology, which operates from a small farmhouse in north Devon, is currently in Tasmania hunting down clues to prove the thylacine, commonly known as the Tassie tiger, still exists."

Nobody has declared the Thylacine extinct. According to the Tasmanian Parks and Wildlife Service, the Thylacine is listed on their Threatened Species list, and is "presumed extinct": "Listed as presumed extinct under both the Federal and State Threatened Species Protection Acts. This means thylacine have not been officially sighted in the wild or captivity for at least 50 years." http://www.parks.tas.gov.au/index.aspx?base=971 I hope this clarifies the situation. Regards, William Harris • (talk) • 11:59, 22 April 2017 (UTC)
The IUCN Red List says it is extinct, and that is the generally recognized international authority. No one has provided proof otherwise. There have been no verified road kills or other carcasses recovered, and no adequate-quality videos or photographs. —BarrelProof (talk) 21:30, 22 April 2017 (UTC)
"Presumed extinct" may be a semantic remnant of the Endangered Species Protection Act 1992 which classified threatened species as endangered, vulnerable or presumed extinct. It has since been repealed and threatened species are categorised as extinct, extinct in the wild, critically endangered etc. Furthermore, the Threatened Species Kit (2003) which you have linked to is out of date, as noted by the disclaimer, which may be why it uses this old legislative terminology.  NeoGeneric 💬  01:22, 23 April 2017 (UTC)
Based on the evidence provided, that is the official position of the Government of Tasmania. Your comments on how that arose borders on personal conjecture. All that I ask is that people keep an open mind regarding its extinction/non-extinction. Regards, William Harris • (talk) • 21:30, 23 April 2017 (UTC)
"Official position of the Govt of Tasmania"? - you have referenced an outdated resource on the Tas Parks website "specifically designed for school students". I would not call that official. If you want an authoritative answer for the official position of the Govt of Tas, I would suggest the Natural Values Atlas. As I already have a login, to save you and others from having to register for access, here are some of the species details for Thylacinus cynocephalus:
  • Threatened?: Yes
  • State Schedule: extinct
  • National Schedule: Extinct
  • Conservation Significance?: No
  • Biogeographic Origin: Endemic, considered extinct in Tasmania
But I feel this is all an argument on the semantics of "extinction" - something that was known to exist, but can no longer be found. I wish any researchers best of luck in search of the Thylacine, because it is the sum of good evidence which reinforces the idea that something exists, and the lack of which reinforces the idea it can no longer be found. This is the somewhat fundamental idea behind science.  NeoGeneric 💬  05:00, 24 April 2017 (UTC)

Extinction from mainland Australia

"The absolute extinction is attributed to competition from indigenous humans and invasive dingoes."

The "indigenous" should be changed considering context, humans as a species are only native to Africa. Seems oxymoronic to regard humans as native but not dingoes. Please change to "Australian Aboriginals". — Preceding unsigned comment added by 107.77.173.2 (talk) 22:34, 12 June 2017 (UTC)

Cultural references

Crash Bandicoot is a well-known videogame franchise, and Tiny Tiger (one of the recurring bosses) is a Thylacine. Charles Zembillas (one of the main artists for the original trilogy of games) talks about Tiny's origin on his blog, specifically mentioning how his original name was indeed "Tasmanian Tiger". 201.214.215.217 (talk) 22:17, 6 September 2017 (UTC)

  • Is this in any way significant on par with it being on coat of arms, focus of literature and so on? We're not supposed to list every inconsequential appearance of a given species in popular media. Some of the entries present now also seem too WP:trivial. We need less fluff, not more. FunkMonk (talk) 22:32, 6 September 2017 (UTC)
i would suggest that some of the fluff can be transmuted and preserved. Put it into a note, where it's existence would be documented, but it would not clutter the main text in the article. 7&6=thirteen () 18:35, 7 September 2017 (UTC)
