Internationally renowned palaeontologist and Monash University Honorary Research Associate, Dr Anthony Martin has found evidence of a dinosaur burrow along the coast of Victoria, which helps to explain how dinosaurs protected themselves from climate extremes during the Cretaceous period -- the final era for dinosaurs before their extinction.
On the heels of his discovery in Montana of the first trace fossil of a dinosaur burrow, Emory University paleontologist Anthony Martin has found evidence of more dinosaur burrows -- this time on the other side of the world, in Victoria, Australia.
BUFFALO, N.Y. -- Modern glaciers, such as those making up the Greenland and Antarctic ice sheets, are capable of undergoing periods of rapid shrinkage or retreat, according to new findings by paleoclimatologists at the University at Buffalo.

Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years.
The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles
CORVALLIS, Ore. -- At times in the distant past, an abrupt change in climate has been associated with a shift of seasonal monsoons to the south, a new study concludes, causing more rain to fall over the oceans than in the Earth's tropical regions, and leading to a dramatic drop in global vegetation growth.
CORAL GABLES, FL, FL (May 27, 2009)--People have always wondered where we, our Earth, our galaxy, come from.
WALNUT CREEK, CA - After a genome is sequenced and automatically annotated, researchers often manually review the predicted genes and their functions in order to improve accuracy and coverage across the vast genetic code of the particular target organism or community of organisms.
Monsoon is a global system, and many arrays of evidence indicate that it drives long-term cyclicity of the carbon reservoir in the global ocean. The new view is introduced in a substantial paper in Issue 7 (April 2009) of Chinese Science Bulletin.
Boulder, CO, USA - Hot topics include (1) opposition to the idea that chevron-shaped dunes are indicative of mega-tsunamis; (2) discovery of a complex microbial community that extends the fossil record of cavity-dwelling life by more than 1.5 billion years; (3) documentation of nanoscale, respirable cristobalite fibers in volcanic ash from Chaiten volcano and the likely adverse health effects;
HANOVER, NH - Dartmouth researchers have determined that the presence of the rare element osmium is on the rise globally.
Increased growth in Antarctic sea ice during the past 30 years is a result of changing weather patterns caused by the ozone hole according to new research published this week (Thurs 23 April 2009).
Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change.
Researchers have found that dust blown south to Antarctica from the windy plains of Patagonia - and deposited in the ice periodically over 80,000 years - provides vital information about glacier activity.
A University of British Columbia researcher has discovered dozens of species of jumping spiders that are new to science, giving scientists a peek into a section of the evolutionary tree previously thought to be sparse.
The year is 2065. Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five minutes.
