Murgon fossil site : ウィキペディア英語版
Murgon fossil site
The Murgon fossil site is a paleontological site of early Eocene age in south-eastern Queensland, Australia. It lies near the town of Murgon, some 270 km north-west of Brisbane. The Murgon site is important as the only site on the continent with a diverse range of vertebrate fossils dating from the early Paleogene Period (55 million years ago, only 10 million years after the extinction of the dinosaurs), making it a crucial period in mammal evolution. It is also important in demonstrating Australia's Gondwanan links with South America in the form of similar fossils from the two continents.
==Geology==
Volcanic rock which has been estimated to be 40 million years old overlays the site. Therefore, the Murgon fossils must be older than this.
The site is mostly clay which was laid down in a lake which formed in a volcanic crater.
