Fossil remains of an extinct species of a large ground-dwelling bird recently discovered at Riversleigh, are believed to date back approximately 17 to 18 million years.
Closely related to today's native lyrebirds, the fossil found within Boodjamulla National Park (Aboriginal Land) provides key evidence that the roots of Australia's unique songbirds run deep.
The fossil, a wrist bone, is anatomically similar to modern lyrebirds and suggests that the extinct species – Menura tyawanoides – was a large, mainly terrestrial bird with reduced capacity for flight.
It is believed that the species lived in the dense understorey of ancient lowland tropical rainforests.
This discovery highlights the value of Riversleigh, part of the Australian Fossil Mammal Sites World Heritage Area, as a window to the past and indicates why it is one of the top 10 fossil sites in the world.
Not only do fossil records enrich our understanding of Australia's natural heritage, but they also reinforce the scientific importance of protecting sites that continue yielding world-class palaeontological insights.
Paleo-tourism presents a huge opportunity for Queensland and is expected to generate $82 million for the economy in the next 15 years.
Ranger Lea Ezzy said Boodjamulla National Park (Aboriginal Land) is one of Queensland's most popular outback national parks with plenty of paleo-tourism experiences.
"Boodjamulla National Park (Aboriginal Land) also encompasses Lawn Hill Gorge, renowned for its stunning emerald-green waters, towering sandstone cliffs and diverse wildlife.
"From its exceptional views and walks to its fossil deposits, which are among the richest and most extensive in the world, this natural and cultural haven is a must-visit when in the Outback.
"We are dedicated to protecting and preserving this protected area for generations to come."
