Fossils and geological time

Geological TimeWalk

Geoscience Australia's Geological TimeWalk is a physical representation of geological time in the landscaped gardens of Geoscience Australia. The TimeWalk leads you on a 1.1 kilometre journey through the Earth's 4600 million year (Ma) history and represents the evolution of the Earth from its formation though to the present day.

Since the TimeWalk's installation in the building in Canberra in 2009, large rock samples have been collected from around Australia and put on display at locations along the TimeWalk that reflect their age. Each rock has a story to tell, with geological, economic, environmental and/or cultural significance.

Explore the TimeWalk online
The Geological Timewalk is now available online thanks to Google street-view technology which has captured the journey digitally. Guide your way through the rocks on display and enjoy the walk without having to brave the elements.

Timescale Bookmark
A simple geological timescale suitable for colour printing at A4 size. The ages and names of major geological time periods and eras are shown. A brief explanation of the geological timescale and how it is developed is provided on the 'back'. Please note that the timescale is not to scale.

Geological TimeWalk Booklet
The Geological TimeWalk booklet describes major geological, climatic and biological events that have occurred over time. Geological events include continental drift, the break-up and amalgamation of continental land masses, mountain building and major volcanic eruptions.

Mobile App

Geoscience Australia Time Walk
The TimeWalk iPhone application guides visitors along the TimeWalk in Geoscience Australia's Canberra grounds. It gives the opportunity to read, hear and learn about the significance of rocks located along the walk and discover interesting facts about Earth's geological history along the way.

Geological Timescale: Australia through time
This iPad app provides users with information about the periods of the Geological Timescale, including details of life and minerals formed during each time period. Animated Paleogeographic maps also show the changing shape and position of the continents from 600 million years ago to the present day.



Geological Timescale
A geological timescale suitable for printing at A4 or A3 size and displaying on the wall of a classroom. The timescale subdivides the 4.6 billion years since the planet formed into a series of time units.
