Welcome to Thylacoleo Revealed - A Natural History of the Marsupial
Lion, a compendium of information on the extinct marsupial family
Thylacoleonidae. Thylacoleonids are predatory marsupials that lived
in Australia from the Late Oligocene until the end of the Pleistocene.
Members of this marsupial family varied in size from that of a squirrel
to nearly as large as an African lion. The largest and most well
known species of the family is Thylacoleo carnifex.
Commonly referred to as the "marsupial lion", T. carnifex was a
robustly built Ice Age animal with a broad skull and forward-facing binocular
eyes. Among its most unusual features is its dentition, which includes
enlarged incisors and shearing premolars. The first evidence for
the existence of
Thylacoleo came from fossil material collected
in the early 1830s by Major Thomas Mitchell in the Wellington Valley region
of New South Wales. The genus was first described by the famous British
anatomist Richard Owen, in 1859.
