Victoria’s Coastline: A Fossil Hunter’s Paradise Unearths Ancient Secrets
A remarkable stretch of coastline in Victoria, Australia, is yielding unprecedented fossil discoveries, offering a unique window into life on Earth millions of years ago – and inviting the public to participate in the process. From ancient whale bones to prehistoric shark teeth, the shores of Jan Juc and beyond are rewriting our understanding of the planet’s evolutionary history.
A Window into the Oligocene Epoch
At Jan Juc, nestled between cliffs and the sea on Victoria’s Surf Coast, researchers are meticulously scouring the shore platform for evidence of life dating back 25 million years. “You can be there discovering a fossil that might change our understanding of the evolution of life on Earth. And you’re sharing it with a family that’s just gone down to the beach for the day,” explains Dr. Erich Fitzgerald, senior curator of vertebrate palaeontology at Museums Victoria Research Institute.
The area’s dynamic geology, shaped by powerful Southern Ocean swells eroding the rock face and shifting boulders, continually reveals new fragments of the past. These remnants, often whale bone or shark teeth, hail from the Oligocene epoch, a pivotal period in the evolution of whales and other marine life. For Dr. Fitzgerald, the site is “like a magnet,” promising new discoveries with each visit.
Ancient Giants and Miniature Relatives
Fossils unearthed at Jan Juc have already revealed a fascinating array of prehistoric creatures. These include the Janjucetus dullardi, a tiny-toothed baleen whale, primitive dolphins with elongated jaws, and penguins exceeding one meter in height. These creatures were likely preyed upon by Carcharocles angustidens, a massive prehistoric shark and ancestor to the infamous megalodon.
Beyond the Outback: Fossils Close to Home
While fossil hunting is often associated with remote outback locations like Winton, “Australia’s dinosaur capital” in Queensland, Victoria offers accessible opportunities for both amateur and professional paleontologists. “You can find fossils of nearly all geological periods in Victoria… if you know where to look,” states palaeontologist Professor John Long, who began his search for specimens at the age of seven.
Victoria’s unique geological landscape, characterized by the Great Dividing Range and millions of years of upheaval, exposes a comprehensive geological timescale, from the Cambrian period to the recent past.
A Storied Fossil Record
Victoria boasts a rich fossil history, beginning with the discovery of Australia’s first known dinosaur specimen – a claw from a small carnivore – near Inverloch in 1903. Since then, the state has yielded remarkable finds, including some of the oldest land plant fossils, extinct marine organisms called graptolites, early fish from the Devonian period, and world-renowned polar dinosaurs.
Recent discoveries include fossilized claw prints near Mansfield, dating back 354 million years, representing the oldest evidence of amniotes – the ancestors of reptiles, birds, and mammals. This discovery was made by local residents Craig Eury and John Eason, inspired by a talk given by Professor Long. “We found plates of ancient armored placoderms. I just showed them how easy it was to actually find stuff, once you knew what you’re looking for. Since then, they’ve been going out by themselves and walking the whole of the basin, finding more material,” Long recalls.

The Public’s Role in Discovery
Sally Hurst, a palaeontologist and archaeologist behind “Found a Fossil,” emphasizes the crucial role of the public in uncovering these treasures. “Most of the time they are not found by scientists, they’re found by members of the public,” she notes. Fossils can be any trace of past life – plants, bacteria, or animals – that have become mineralized over time.
Hurst advises aspiring fossil hunters to visit museums to familiarize themselves with potential finds and to look for unusual textures in rocks. However, she stresses the importance of following guidelines: no digging without a permit, and if a fossil is discovered, photograph it, record its GPS location, and contact the museum or Found a Fossil. A scale object, like a ruler or coin, should be included in the photo.
Urban Fossil Hunting and Deep-Sea Exploration
Palaeontologist Ben Francischelli frequently searches for fossils at Beaumaris beach, just south of Melbourne’s city center. The beach’s ochre cliffs are a treasure trove of marine and land fossils from 5 to 6 million years ago. He recommends visiting at low tide and exercising caution due to potential cliff collapses. “All you need are your eyes,” he says, noting that heart urchins and shark teeth are common finds.
Francischelli prefers diving, carefully avoiding disturbance to local marine life like blue-ringed octopus and giant smooth stingrays. “My favourite thing to do is to just hold my breath and sink to the bottom, and then kind of walk like a moon man looking for fossils.” Discoveries from Beaumaris are displayed at the nearby Prehistoric Bayside Museum.
Dinosaur Dreaming on the Bass Coast
For those seeking dinosaurs, the 40km coastline between San Remo and Inverloch is a prime location. Lesley Kool, coordinator of the “Dinosaur Dreaming” project, has led teams uncovering a diverse range of Cretaceous dinosaurs for 30 years, including ornithopods, ankylosaurs, theropods, plesiosaurs, pterosaurs, early mammals, and the amphibian Koolasuchus cleelandi.
This area, once a rift valley between Australia and Antarctica 125 million years ago, offers a unique glimpse into a polar environment. Guided tours are available through the Bunurong Environment Centre, but collecting fossils requires a permit.
Collaboration and Conservation
Dr. Fitzgerald underscores the importance of public involvement. “We really do rely on the public doing the right thing and letting us know when something really significant has been found,” he says, emphasizing the need to collect, preserve, and share these discoveries for scientific study and public enjoyment. Finders are recognized in the museum’s collection register.
Ultimately, the search for fossils is a deeply enriching experience. “The search for fossils and learning about our deep prehistoric past must be one of the most satisfying, enriching activities,” Fitzgerald concludes. It’s “95% walking and looking,” he says, which “forces you to actually stop and just pay attention to your surroundings,” fostering a deeper connection with nature and our place in the universe.
