FAQs About Dinosaurs

What is the difference between megafauna fossils and dinosaur fossils?

Dinosaurs are reptiles that went extinct 64 million years ago. They grew to gigantic sizes.  They lived in a time when Australia was a very different place to what it is today, and part of the ancient landmass called Gondwana. The Eromanga dinosaurs are estimated to be 95-98 million years old and lived during the late Cretaceous.

Megafauna are the group of animals that evolved after the dinosaurs died.  They were very large marsupials, reptiles and flightless birds and went extinct about 20,000 years ago.  Some of their descendants still exist today in much smaller forms such as kangaroos, wombats, komodo dragons and crocodiles.  The Eulo megafauna lived during Pleistocene approximately 50,000 to 100,000 years ago. 


Why do the Eromanga dinosaurs and the Eulo Diprotodon (Megafauna) have common names like Cooper, George, Sid, Zac and Kenny?

These are identifying names we give a new important dinosaur or megafauna discovery so we know which individual we are talking about. In many cases with the dinosaurs they will be scientifically described as completely new dinosaurs and then they are given a special scientific name.  If they are not a new species then they will already have a special scientific name.  ‘Kenny’ has a scientific name already, Diprotondon optatum.


Frequently Asked Questions

How do you recognise dinosaur fossils’

Fossils are predominantly black coloured and will look different to other rocks in the same area, plus they are heavier than rocks. Often they are broken into irregular fragments and have a porous structure.

Interesting fact: Sometimes if you put your tongue on the rock and it sticks a little bit this can also mean it is a fossil.
