VIII. On the fossil mammals of Australia.—Part II. Description of an almost entire skull of Thylacoleo carnifex , Ow

Abstract

In this Part the author gives additional cranial and dental characters of the extinct marsupial carnivore, Thylacoleo , deduced from examination of better-preserved fossils, obtained from freshwater deposits in Darling Downs, Queensland, Australia. The forepart of the skull, wanting in the first-described specimen from similar deposits in the province of Victoria, is preserved in the present specimen, showing the premaxillary bones, which are relatively larger than in placental felines. Each bone has three teeth, of which the foremost is developed into a tusk, the second and third being very small.
