Only preliminary work had been done at the megafauna sites at Eulo in 2011 and it was only after a full two week dig in 2012 that the full extent of the fossil field became apparent. It is undoubtedly one of the most prolific and well preserved megafauna sites in Australia and contains the full spectrum of mega and microfauna fossil remains. It has certainly added a whole new dimension to the OGF program as well as greatly extended our area of operations. It is undoubtedly one of the most prolific and well preserved megafauna sites in Australia. The new megafauna collection has added to the workload in the prep lab but I feel it has motivated the lab to have their most productive year yet. Our trainee lab technician, Tanya Hudson and Robyn Mackenzie have put in a full prepping program in 2012. The part time work by Jo Pegler has also contributed to a full program. The bones from the skeletons of two dinosaurs are nearly finished and ready for scientific analysis and all the bones have been finished from one of the diprotodon specimens from Eulo. The lower jaw of COOPER COUNTRY one diprotodon is one of the most spectacular megafauna bones in Australia and a large crowd at the visitor’s day at Eulo were lucky enough to witness the unveiling of this remarkable exhibit. We continue to seek funding for the Natural History Museum and were unlucky to miss out in the second Regional Development Australia round after being identified as the number one project for the whole Darling Downs and Southern QLD region. We continue to apply through subsequent rounds and see sourcing funding for this building as our number one priority in 2013. Notwithstanding the failure to source funding, 2012 has been another year of achievement, discovery and productivity from the prep lab and we look forward to 2013 with much enthusiasm and confidence. Once again I would like to thank all our supporters and sponsors and especially the team from Queensland Museum who have collaboratively assisted OGF to continue to discover, prepare and preserve one of Australia’s most prolific, diverse and amazing fossil collections.

VOLUME V PAGE 3 Collection’s Manager’s Report All the 2011 Eulo megafauna material was processed before the beginning of the 2012 field season. Tanya and Robyn spent a week making a very special cradle to enable the remarkable lower jaw bone of ‘Kenny’ the Diprotodon to be able to make the journey back to Eulo for the visitors day at the property where the megafauna fossils were found. Carefully packed in specially purchased 400L icebox this lower jaw travelled safely to and from Eulo. It was well worth the effort as this specimen is always a crowd stopper. The work put into the cradling this specimen and all the other Diprotodon vertebra were testimony to the good work happening in the OGF prep lab. The priority in the lab is to complete more dinosaur material. Very good progress has been made with these extremely large and time consuming bones. Some are particularly challenging as the bones from one specimen have been crushed. Queensland Museum Technician Jo Wilkinson, once again filled our lab with cheer and spent a very valuable week doing some of the final preparations on some important dinosaur bones. A Fossil Heritage survey was carried for Santos on the pipeline easement and the 2D seismic lines for the Mt. Howitt exploration area. One new dinosaur site was located but was not in any immediate threat from this activity. The other five existing sites were resurveyed by RPS and the Collection Manager. One of the 2D seismic lines went within metres of one of the existing dinosaur sites so this line was moved 200m away from this existing dinosaur site. Information on how to recognise dinosaur sites was passed onto the surveyors and they were taken to see one of the dinosaur sites which had not been worked on and they also visited the lab. To wind the year up on Christmas Eve, the family members of Robyn Mackenzie all turned up at the lab to help perform a very successful flip of a huge dinosaur femur, pictured below.

It dates the in-situ sediments next to the fossils. Collecting the OSL cores in the field during digs is very important to enable dating of the bones necessary for researchers and research funding. It is a lengthy and expensive process to OSL date the cores and Griffith University is one of the few places with the skills and equipment to offer this service. Griffith’s Dr Tim Pietsch attended the Eulo megafauna dig and trained OGF technicians, Tanya and Robyn on the field collection of these cores. Robyn and Tanya then attended a 5 day course at Griffith to learn the skills to enable them to process the cores taken at OGF digs. It is planned to include part of this processing at the Eromanga Natural History Museum and then send this processed material to Griffith to be analysed in the OSL machine.

COOPER COUNTRY VOLUME V PAGE 7 Interesting Insects A Quilpie local spotted an unusual bee during the year and referred it to the Outback Gondwana Foundation for identification. With the help of Dr Christine Lambkin, Curator of Terrestrial Environments (Entomology) at the Queensland Museum, the species was identified as a sand wasp in the genus Bembix. This one is most likely Bembix Magarra but there are many other species of Bembix and it could be something completely different. PAGE 8 Science and Art Adele Outterridge and Wim de Vos were the 2012 Artists in Residence for the Eulo Megafauna Dig. Adele and Wim have a personal connection with the Eulo area after visiting and working in the area a few years ago. These two well known and respected artists live in Brisbane and run The Studio West End, established 1998. Adele and Wim travel widely lecturing and teaching workshops. Both Adele and Wim were participating artists in the The Extant Landscape, Eromanga Basin Exhibition. Wim’s inspirational artwork of the megafauna sites was a standout piece at the exhibition.

The Extant Landscape Ten Queensland Artists have come together to celebrate the diversity and vastness of the Eromanga Basin landscape. Proceeds from the exhibition will go towards the Outback Gondwana Foundation Building Fund. The Extant Landscape is expressed through multiple media as the artists work in oil, acrylic, print, paper, perspex, photography, digital, metal and precious gems. The Exhibition was held in the Richard Randall Art Studio, at the Mt Cootha Botanic Gardens. The Preview Event was on Friday the 30th of November, 2012 69pm. The exhibition continued over the weekend. The winner of the painting "The Dig", donated by Leah Cameron, was won by Grace Pegler of Monler Station, Eromanga. Congratulations Grace!

Tanya Hudson paid a visit to Tibooburra International Plant Propagators Society Annual Conference Toowoomba May 2012 CEO Anita Milroy was invited by Conference Convenor and Highsun Managing Director Brad COOPER COUNTRY Skinner to present at the IPPS annual conference in Toowoomba. She presented a 20-minute botanical discussion on the evolution of plants from prehistoric to modern time with emphasis on their adaptation strategies to climate change. . VOLUME V PAGE 11 Did you know? The word diprotodon means two forward teeth, in honour of the animals buck-toothed incisors. The first diprotodon fossils were discovered in the early 1800s and sent to Britain for scientists to study. Opinions vary about when the diprotodon became extinct, with earlier estimates at about 30,000 years ago and later estimates about 50,000 years ago. The alkalinity in the clay around Eulo helped to preserve the fossils in the area. Don’t forget the giant Kangaroos The biggest kangaroo ever to have lived in Australia was the procoptodon goliah. It was three times the size of the modern red kangaroo. Thank you to our generous Sponsors And supporters NEWSHAM FAMILY EULO
