Step back half a billion years with the 2026 Creatures of the Palaeozoic Medallion Cover from Australia Post, a stunning tribute to the bizarre and groundbreaking creatures of the early Cambrian Period. The central 65mm medallion, crafted in zinc alloy with advanced digital printing and protective epoxy dome, vividly recreates real fossils from the world-famous Emu Bay Shale on Kangaroo Island—illustrated with palaeontological accuracy by Peter Trusler in partnership with expert Diego Garcia-Bellido. Paired with the four beautifully designed $1.70 stamps that highlight these ancient innovators and the evolutionary leap of hard-shelled life, this cover celebrates one of the most transformative chapters in Earth's history right here in Australia.

Featuring a First Day postmark from Adelaide and premium philatelic packaging, this limited PMC is a standout addition for collectors who appreciate the intersection of science, art, and postal history. Whether expanding a stamp collection, honouring Australia's fossil heritage, or seeking an educational display piece that sparks wonder about our planet's distant past, this innovative medallion cover delivers exceptional detail.
