Dreadnoughtus: discovery of a massive, herbivorous dinosaur announced

Drexel University professor Ken Lacovara has recently unveiled a new supermassive dinosaur species he discovered and unearthed with his team between 2005 and 2009 in Argentina.

Weighing in at nearly 65 tons, Dreadnoughtus schrani is possibly the largest land animal ever found.  The skeleton discovered by the team is believed to be nearly complete.  In this video, Professor Lacovara describes the significance of this find.

 

Introducing AIGeoscope

AIGeoscopeThumb150AIGeoscope is a new weekly publication from the Australian Institute of Geoscientists that provides a snapshot of geoscience issues that have attracted attention around the world.  

AIGeoscope draws content from a wide range of sources, including the AIG web site and YouTube channel, which span a comparably broad range of topics and highlight the diversity of activities undertaken by, and of interest to geoscientists. The result is an electronic newspaper that will hopefully appeal to geoscientists and members of the public interested in aspects of geosciences.  AIG news and events features prominently in the new publication.  The newspaper joins AIG’s existing Internet resources including the Institute web site, Linkedin group, Facebook page and Twitter feed.

AIGeoscopeSample

The concept has been trialled over the past few weeks and attracted positive feedback from readers ranging from exploration geoscientists to school teachers, who have already used the newspaper as a classroom resource.

We hope that readers will enjoy the newspaper and that it will help to raise awareness of the diverse contribution of geosciences to communities globally.

The newspaper is updated early each Monday morning and available, free of charge, at aigeoscope.aig.org.au  You can also subscribe to AIGeoscope by RSS to be advised of updates between issues, or each Monday.

The Presenter

David Groves received a BSc Honours (1st class) and PhD from the University of Tasmania. He joined the University of Western Australia (UWA) in 1972 as Lecturer, and became full Professor and Founder and Director of the Key Centre for Strategic Mineral Deposits (later Centre for Global Metallogeny) in 1987. His main expertise has been in orogenic gold deposits globally and temporal evolution of mineral deposits. He has been President of the Geological Society of Australia, SEG and SGA, and has been awarded 11 medals for his research, including both the Gold Medals of SEG and SGA for lifetime contributions to economic geology, and the Geological Association of Canada Medal. Since retirement, he has been awarded an honorary DSc from UWA and consulted to the gold exploration industry and investment groups on all continents, mainly for Canadian companies in Africa and Brazil. This has resulted in one significant discovery and several on-going technical successes. He has also presented workshops on orogenic gold in Australia, Canada, New Zealand and UK, and on geological aspects of the business of exploration in Canada and the UK to brokers and investors.

Mineral exploration key to industry’s future: AMEC

“The  Mineral and Petroleum Exploration, Australia June 2014 quarter  report released today by the Australian Bureau of Statistics shows a slight increase in mineral exploration expenditure and metres drilled on the back of consistent decreases,” said Simon Bennison, Association of Mining and Exploration Companies CEO.

“This is not surprising given exploration is a seasonal industry and as such the seasonally adjusted estimate shows a decrease in expenditure and metres drilled.

“These levels continue to be historically low. Investment in exploration on new deposits is similar to post GFC levels in the March 2009 quarter which reflects the challenges currently facing the industry.

“Given the long lead time from discovery to a producing mine, these figures are extremely concerning. Investment in greenfields exploration is essential for new discoveries to secure the future of the Australian mining industry.

“The industry contributes 10 percent of Australia’s Gross Domestic Product and employs around 250,000 people in Australia. The industry is essential to support Australia’s economy and Government revenue streams into the future.

“Australia’s reputation must be restored. In 2013 67% of exploration funds raised on the ASX went to international projects. The number of Initial Public Offerings on the ASX also dropped from 126 in 2007 to just three this year.

“It is essential then that the Federal Government’s proposed Exploration Development Incentive initiative is quickly legislated. This along with the repeal of the mining tax will go a long way to restoring Australia’s international competitiveness and increasing investment to stimulate the sector,” said Mr Bennison.
