Lost Rainforest of Australia Revealed by Giant Fossil Trapdoor Spider

Scientists have discovered an exceptionally preserved fossil of a large spider, named Megamonodontium mccluskyi, that lived in a rainforest in Australia during the Miocene epoch. This is one of the few spider fossils found in Australia and the first fossil of a spider from the brush-footed trapdoor spider family. The discovery sheds light on the extinction of spider species and fills gaps in understanding the region's past. The spider's closest living relative inhabits wet forests, suggesting that the species went extinct as Australia became more arid. The fossil's remarkable preservation allowed researchers to observe minute details, classifying it as a close relative of the modern Monodontium genus but approximately five times larger in size. This discovery may also provide insights into Australia's changing landscape.
