Nearly two decades of research conducted by the University of New England (UNE) into a remarkable deposit of ancient fossils discovered at Emu Bay on South Australia’s Kangaroo Island has culminated in a stunning new limited edition stamp collection released today by Australia Post. The stamps showcase full-color artistic reconstructions of these prehistoric marine animals, offering a vivid glimpse into a long-lost world.
The Emu Bay Shale site, a paleontological treasure trove, has yielded fossils dating back 512 million years to the Cambrian Period – a pivotal era in Earth’s history when complex life first began to evolve in the oceans. This new stamp series isn’t just a philatelic offering. it’s a celebration of Australian scientific achievement and a window into our planet’s distant past.
UNE palaeontologist Professor John Paterson, who co-led the research alongside colleagues from the South Australian Museum and Adelaide University, emphasized the significance of the project. “These amazing artworks are the culmination of nearly 20 years of intensive scientific research on one of Australia’s most important fossil sites,” he said. “The artist, Peter Trusler, has done a superb job of bringing these amazing extinct sea creatures back to life.”
The Cambrian “explosion,” as it’s known, represents a period of rapid diversification of life. The fossils from Emu Bay provide crucial insights into the ancestors of modern animals, including snails, sea urchins, crustaceans like crabs and prawns, and even early chordates – the group to which humans belong. The site is unique in the southern hemisphere for preserving delicate, non-mineralized external skeletons and some internal soft tissues, offering an unprecedented level of detail.
A Glimpse into the Cambrian Seas
Among the creatures featured on the stamps is Anomalocaris daleyae, a giant arthropod that dominated the Cambrian seas as an apex predator. Reaching lengths of up to 60 centimeters, this formidable animal possessed large, spiny head appendages used to capture its prey. But perhaps its most striking feature was its pair of stalked eyes, boasting over 24,000 lenses each – rivaling the visual acuity of modern dragonflies.
“These sophisticated eyes gave Anomalocaris extremely powerful vision for seeking out its prey,” explained Professor Paterson. “The discovery of exquisitely preserved specimens from the Emu Bay Shale shows that some of the first marine animals were already well-equipped killers.” The research team’s findings, detailed in numerous publications over the past two decades, demonstrate that the Cambrian Period wasn’t a simple beginning of life, but a time of complex ecosystems and sophisticated predators.
The artistic reconstructions featured on the stamps are based on the latest scientific research by Dr. Diego Garcia-Bellido of the South Australian Museum and Adelaide University, and Professor Paterson from UNE-Armidale. Renowned scientific illustrator Dr. Peter Trusler meticulously crafted the images, ensuring anatomical accuracy and bringing these ancient creatures to life with vibrant color. The Guardian reports that Trusler was deeply engaged with understanding the anatomy and lifestyles of these unusual beasts.
A Legacy of Research and Public Engagement
The unveiling of the stamp collection is accompanied by a new display at the South Australian Museum, showcasing the full-color reconstructions. The museum’s exhibit, titled “Creatures of the Palaeozoic,” highlights the significance of the Emu Bay fossils and their contribution to our understanding of early life on Earth. Play & Go Adelaide notes that the fossils were first discovered in the 1950s by South Australian scientist Reg Sprigg, but have been the focus of intensive research since 2007.
Professor Paterson hopes the stamps will raise public awareness of Australia’s paleontological heritage. “I hope these stamps will highlight the importance of these ancient animals and inform the general public on the global significance of Australia’s spectacular palaeontological heritage,” he said. “This milestone reflects UNE’s commitment to advancing palaeontological research and sharing Australia’s natural heritage with the world.”
Australia Post’s decision to feature this research on a stamp collection underscores the importance of scientific discovery and its ability to connect the public with the wonders of the natural world. UNE Times reports that the stamps are a limited edition release, making them a collectible item for both stamp enthusiasts and paleontology buffs.
Looking ahead, the research team at UNE, the South Australian Museum, and Adelaide University will continue to analyze the fossils from Emu Bay, seeking to unlock further secrets about the Cambrian Period and the evolution of life on Earth. The ongoing study of these ancient creatures promises to refine our understanding of the origins of animal life and the forces that shaped our planet’s biodiversity.
