Two new and very exciting papers on the thylacine!

Abstract

David Fleay's 1933 motion film footage of the last captive thylacine at the Beaumaris Zoo in Hobart was thought to be the only film record of this thylacine. The authors provide evidence to confirm that two earlier motion picture films, erroneously dated to 1928, also show the last captive specimen at the zoo.

Abstract

The most comprehensive assessment of the breeding season of the thylacine was that undertaken by Eric Guiler of the University of Tasmania in 1961. Guiler based his study on a retrospective analysis of government bounty records. The authors contend that the bounty records contain inherent anomalies that undermine Guiler's findings, and argue that historical newspaper reports, together with museum and zoo records, provide better data to determine the natural boundaries of the breeding season of the thylacine.

Interestingly, Pertinax from the Zoochat forum commented the following on my thread on that forum:

"Re the date of the films, I discussed this previously with Cameron Campbell- the snare mark is evident in the same place on the animal's right hind leg in all three films, so clearly they were all of the same individual- the last thylacine at the Zoo- and so were all made 1933 onwards, not before."

I assume there's something about thylacines in this paper?

Freeman's words from her Facebook page about this article:

"A response to searches and reported sightings of the species and the idea that they still exist. It's the lead article in this glossy magazine and includes artworks by Rew Hanks, Graham Lang and Jan Ford."

I've noticed another anomoly in this. Lord said there were no Thylacines in the Hobart Zoo as of(date) February 1930 and also that 'the museum had not received a specimen for four years'. Yet earlier its stated the one that died in 1929 was 'sold to the museum for £5'  So a bit of a discrepancy there unless its meant the museum hadn't received a specimen from the wild during that period.

It's the same with Paddle's last straw paper, there he places a thylacine the last present in 1928 as dying sometime before the March 31st 1930 stock report, one or two months respectively after the two Stead articles of January and February, and the C. Lord article of late January that year.

He also says it was seven months after this before the zoo acquired another tiger(in October, which Campbell suggests is the Delphin brother's tiger), before contradicting himself by citing an 'adult male' arriving at the zoo in the June. It's a bloody mess.

Nice to see you here.

What they're saying is, maths says thylas are extinct.

[Ian Thomas]

On other hand, thylas probly don't keep up with maths.

The data coming out is only as good as the data going in and I am always suspicious that not all the facts are available; I never doubt the math just the source.

BS in, BS out.

In IT terms GIGO (garbage in garbage out).
