Eromanga/Cooper Basin Discoveries


Natural History Society



Your donation will help ensure that Australia’s fossil, cultural and natural heritage is not lost to science or the Australian community but discovered, preserved and accurately documented for perpetuity. South west Queensland, is a unique region of Australia with so much still to be discovered and recorded... the history books on Outback Gondwana are yet to be written.

Following the discovery of a single chunk of bone in 2004 by the son of South West Queensland landholders, annual fossil digs have been organised at Eromanga and nearby localities in the SW region.


Many discoveries have been made since that initial find. To date six distinct dinosaurs have been discovered from the first two sites. There are at least seven other known sites in SW Qld yet to be excavated. Detailed information about each of the discoveries is being added to this site as it becomes available.


Scientific classification of most of the finds is still pending.

Eromanga/Cooper Basin’s Fossil Finds (so far!)

‘Gibba’ (Chelid Turtle)
  and many other extinct micro & megafauna finds soon to be announced.


Please note these names are nicknames only given to the new dinosaur discoveries purely as a means to identify them until they are scientifically described.


Interesting facts about the Eromanga Dinosaurs:

  • Australia is one of the last frontiers for dinosaur discoveries and research
  • South-west Queensland is Australia’s newest frontier for dinosaur discoveries and research
  • Eromanga Dinosaurs are over 1000 kms away from other Australian dinosaur discoveries
  • Largest dinosaurs ever to be discovered in Australia
  • Largest animals that has ever walked the Australian continent
  • Titanosaurs were the largest ever land-dwelling animals in the world
  • Recent discoveries represent some of the most complete dinosaurs in Australia
  • Little has been know about Titanosaurs in Australia, until these recent discoveries



OGF fossil preparators, Queensland Museum technicians and volunteers prepare all the Eromanga dinosaur’s bones in a purpose build field museum about 30kms from the excavation site. This field museum is funded and run by the Outback Gondwana Foundation .



As each of the Eromanga Dinosaur’s are excavated, prepared and scientifically described, the bones will be on public display in the planned Eromanga Field Museum of Natural History, South-west Queensland and housed in accordance to the rules of the International Code of Zoolological Nomenclature and the National Standards for Australian Museums and Galleries.



Fossilised dinosaur bones

Have you ever wondered how

to find a piece of dinosaur bone how it can be deciphered?


Look here to see How to recognise dinosaur fossil sites


All the information listed below can be found out just by examining the small piece of dinosaur bone in the picture and knowing its location:


Age: approx 95 million years

Location: Eromanga, Australia

Type of dinosaur: large plant eater

Type of bone: vertebra (fragment of internal structure)


Please remember that you must obtain permission from the relevant authorities and landholders before surveying, collecting or excavating from a site.



Time Line of the Eromanga Dinosaur Project

In 1998, Dr Paul Sereno (Palaeontologist, University of Chicago, USA) along with student, Jonathan Marcot, Dr Ralph Molnar (Curator, Geosciences, Queensland Museum) and Joanne Wilkinson (Technician, Queensland Museum) visited Plevna Downs. They were searching for Cretaceous vertebrate fossil material – nothing was found at this time.

In 2004, the first piece of dinosaur bone was discovered by the 14 year old son of a landholder marking the first discovery of dinosaur evidence in South-western Queensland.
