Digging up the Diprotodon

Full Day
Book Program
Year Levels


Megafauna are big (mega) animals (fauna). These are animals that lived in Australia up to 100,000 years ago. They were at least 30% larger than any of their extant relatives. There is significant dispute as to whether the megafauna became extinct due to predation by humans or due to climate change.

The Diprotodon, the largest marsupial believed to have ever lived, was the first fossil mammal described from Australia in 1838. Fossil diprotodon skulls have since been found in Bacchus Marsh, and are currently on display at Museum Victoria.

Ecolinc is currently showcasing casts on trackways featuring footprints on the Diprotodon, the giant kangaroo and giant wombat. The trackways were constructed by Museum Victoria and are currently on loan from Federation University.

The Ecolinc Geological Trail features a range of boulders from the Ordovician 444-488 Ma) to Quaternary (0-2.6 Ma) time periods. One contains a fossil plant leaf, which gives an indication of the climate at the time.

Maximum number of students for this program is 50 per day.

No prior knowledge necessary.

Learning Intentions

In this program students will:

  • Understand and predict how megafauna became extinct
  • Examine a range of fossil evidence and understand how this can unlock our understanding of the megafauna and their habitat
  • Understand how rocks are indicators of how the earth’s surface changes over time.


Students will:

  • Uncover the mysteries of ancient rocks in our unique Geological Trail
  • Get hands-on with megafauna trackways and the ‘Great Mummy Mystery’
  • Become part of the archeological team that uncovers megafauna fossil and solves the puzzle of their origin.

Note: This program is strictly 10am-2.30pm and cannot be shortened in time.
