Photograph of the fossilized skull of an Australian carnivorous marsupial from the genus Thylacoleo, the 'Pouch Lion', probably Thylacoleo carnifex. The specimen is shown with an accompanying scale. One of eight photographs sent to the Royal Society by the Australian Museum, Sydney. The photographs are endorsed as being received 13 September 1889. The receipt of these items coincided with the loan to the Royal Society of an original skull by the Department of Mines, Sydney, which was examined by the zoologist Edwin Ray Lankester (1847-1929). This was apparently in support of the refereeing of a paper submitted to the Philosophical Transactions by Richard Owen FRS (1804-1892).
