It had hitherto been generally believed that the
gigantic marsupials were restricted to the continent
of Australia, and did not occur in Tasmania. Jack and
Etheridge (see footnotes) mention their wide distribution on the continent,
and Professor Stirling is of the opinion "that
this great marsupial appears to have had an immense range,
and to have probably wandered over the whole Continent
of Australia." R. M. Johnston, who is better acquainted
with the geology of Tasmania than anybody else, states
that "in Tasmania no remains of the extinct marsupials,
such as Diprotodon, Nototherium, and Thylacoleo, have as.
yet been found either in the ossiferous cavern breccias or in
the older alluvial beds."
It seems rather strange that nobody took the view that
remains of such animals ought also to occur in Tasmania.
Howitt had already, in 1898, expressed the opinion that
Tasmania was connected with the mainland in geologically
recent times, and Hedley in 1903, holds the same view.
Conseqviently, the discovery of remains of a gigantic
marsupial in Tasmania should not have created the general
surpi-ise they did. When, in 1910, the news that bones of
a gigantic marsupial had been discovered in the Mowbray
swamp, near Smithton, became known, the discovery was
at first somewhat discredited. However, confirmation soon
came, and the remains were purchased by the Launceston
Museum from their discoverer, Mr. Lovett. Mr.
Scott, the Curator of the Museum, has since described them
under the name of Nototherium tasmaniense, but I am
somewhat doubtful whether a new species is justified
