Unearthing the Iron-Clad Secrets of McGraths Flat
McGraths Flat, a newly discovered fossil site in New South Wales, challenges traditional beliefs about fossil preservation. Dating back to the Miocene epoch, this site reveals exquisitely preserved fossils in iron-rich sediments, offering new insights into ancient terrestrial ecosystems that differ from typical shale or sandstone formations.

In a groundbreaking discovery, McGraths Flat, located under the farmlands of New South Wales, is challenging long-held views on fossil preservation. This site, stretching back 11 to 16 million years into the Miocene epoch, is rich with fossils that reveal an ancient rainforest ecosystem now lost to dust and drought.
Noteworthy for its strikingly red appearance, McGraths Flat's sedimentary rocks are composed of goethite, an iron-rich mineral. This has preserved an impressive variety of plants, insects, spiders, fish, and even feathers with remarkable detail. The new study published in Gondwana Research aims to redefine our understanding of where and why exceptionally preserved fossil sites exist.
Breaking away from traditional deposits like shale and sandstone, McGraths Flat's ferricrete—a fine-grained cement made from iron—holds extraordinarily well-preserved soft tissue fossils. This discovery opens new doors for paleontologists, offering a roadmap for finding similar fossil sites worldwide. The red rocks here could pave the way for future discoveries in understanding our planet's ancient terrestrial life.
