    Echidna find rewrites natural history books - Australia Network News - ABC News (Australian Broadcasting Corporation)

    It'll be interesting to see how this plays out. There are several possibilities of which I guess the two most likely are as follows. One is that long-beaked echidnas did historically/still do live in northern Australia. Second is that the specimen is mislabelled (e.g. a collection tag from some other specimen was accidentally placed on the echidna specimen at the museum or in transit).

    Very exiting although my first respons (before reading Chlidonias posts) was: Mislabeled!
    With the background info given that became quite unlikely though.Thanks for the link to the article it seems I will have a longer reading session today than planned.

    Who wants to believe this to be true more than me (and maybe ThylacineAlive :D)?

    However, even after reading both articles, all we have to believe that the specimen really came from Australia is a label. The label on my fake Armani shirt doesn't make it real.

    Congolese natives identifying a photo of a sauropod does not maketh mokele mbembe real. ;)

    Thanks for starting this thread though, because the prospect of them still being alive in the Kimberley is extremely tantalising. Let's hope that we can convince Aunty to protect and photograph a long-beaked echidna if she sees one instead of killing it.

    I find this very plausible - the implication does seem to be that it hasn't been seen by natives in some decades, so it is entirely possible it hung on in tiny pockets and has become extinct much more recently than previously thought.

    If you have photos of sauropods, nanoboy, it's time to share!

    Unless more evidence came to light, you have to assume something's gotten mislabeled.

    long-beaked echidna...from Australia

    On the one hand, if there's Long-beaked Echidnas out there, there could be Thylacines [or even Thylacoleos].
    On the other hand, look at Pygoscelis papua [apologies if I haven't spelt that right]....

    Did anyone read the paper? I've going through it and the evidence provided is solid. My first thought was as well that it got mislabeled. It happens too often in collections and in some cases even on purpose (Anyone working with series made by Neumann could testify for this) and knowing it happened and proving it are two different things and cause quite some frustration.
    Reading the paper it becomes clear we are dealing with a quite known skin which has been well documented since 1901. If it has been mislabeled it has been done on purpose. It cannot be excluded but the case Helgen presents is good.

    Anyway very exciting.

    exactly. With my first post in the thread I had thought a mislabelling was most likely; the second article I found provided some better evidence in support of it being real (via aboriginal verbal records); but the actual paper when I found it seems to have quite solid evidence that it is a genuine Australian specimen. The authors do point out there is still the possibility it is mislabelled or had a label switch but it is unlikely.

    They also point out that when the specimen was collected there were more wet forest remnants in the area in the gullies etc, and these are now much fewer. I sort of suspect that the species was holding out in these areas and even small scale hunting eventually eliminated them. However I also feel there's a very good chance they are still out there because it is an incredibly rugged area. I also liked the section where it was suggested that western long-beaked echidnas may feed to a large extent on ants and termites and not largely on worms as commonly stated, which makes their survival in Australia more understandable.

    I was just thinking that perhaps the main threat to long-beaked echidnas if they still occur (apart for the hunting by aborigines) might be foxes. I had a quick google and it seems that while foxes have been recorded in the Kimberley they aren't established there (hence good populations of smaller marsupials and other animals), which is good news.

    Now why didn't you guys say there are aboriginal cave paintings of the long beaked echidna? I just read the journal paper, and I find that to be the most compelling evidence for it having survived into modern times.

    the paintings are generally believed to be of a late Pleistocene age (i.e. not modern!) - although that may simply be because that is when long-beaked echidna species were thought to have become extinct. There are also aboriginal cave paintings of animals considered to be diprotodons, thylacoleo, giant kangaroos, etc. That doesn't mean they survived into the recent past. It just means aborigines have been in Australia for tens of thousands of years.

    We actually thought you would read the paper before jumping to conclusions :p

    But, a lot of those cave paintings were done yesterday (almost). I remember going on a tour of Kakadu, and the tour guide was saying that the paintings in the cave ranged from the 1960s to hundreds of years ago. Our private joke is that they were really painted a few years ago for tourists like us who wouldn't know better.

    Although the aborigines have been here for tens of thousands of years, it does not necessarily mean that those paintings are at least 10,000 years old. Unless organic material was used to make the rock art (like charcoal), I don't believe that the art can be reliably dated. Scientists often say "hey, we know giant kangaroo went extinct 50,000 years ago and here is a painting of giant kangaroo, so it follows logically that is painting is at least as old as that". The other explanation, of course, is that the painting is not that old because the giant kangaroo survived for much much longer.

    I am inclined to believe that the echidna rock art is not very old, unless scientific testing says otherwise. Of course, the stuffed specimen - and not the art - is the topic of discussion.

    Are there any Pleistocene giant echidna subfossils that could be used for DNA analysis to compare with the putative modern Australian sample and see if they are distinct from the New Guinea population?

    Hell, let's make it simpler: for starters, compare this specimen's DNA with the corresponding New Guinea species' DNA to see if they are one and the same. (That wasn't done for this journal paper, was it?)

    No it wasn't done.

    Helgen tantalisingly hinted at the discovery of the third genus of monotremes surviving into the 20th century in May 2011. Had to wait a year and a half, but well worth it!
