(Geological Society of America) The end-Paleozoic witnessed the most devastating mass extinction in Earth's history so far, killing the majority of species and profoundly shaping the evolutionary history of the survivors. Echinoderms are among the marine invertebrates that suffered the most severe losses at the end-Permian extinction.
(Geological Society of America) Shale gas has changed thinking about fossil energy supplies worldwide, but the development of these resources has been controversial. Activists have made claims that hydraulic fracturing may contribute to climate change, threaten groundwater resources, and pose risks to terrestrial and aquatic ecosystems, and human health.
(Geological Society of America) A multi-year study of Egypt's Nile Delta places the country's major breadbasket at serious risk. The soil-rich delta evolved as the result of natural conditions involving the Nile's fresh water flow and transport of sediment northward from Ethiopia, across the Sudan and Egypt to the Mediterranean.

(Geological Society of America) Despite a plethora of exceptionally preserved trilobites, trilobite reproduction has remained a mystery. No previously described trilobite has had unambiguous eggs or genitalia preserved. This study by Thomas A. Hegna and colleagues reports the first occurrence of in situ preserved trilobite eggs from the Lorraine Group in upstate New York, USA.

(Geological Society of America) More than 100 billion micrometeorites (MMs) fall to Earth each year. Until now, scientists believed that these particles could only be found in the cleanest environments, such as the Antarctic. In their new paper for Geology, M.J. Show More Summary
(Geological Society of America) Almost every literate person knows the basics of oil. Almost every literate person also knows something about plate tectonics. While coupling of these two topics has been the focus of many studies, all to date has mostly remained indirect.
Outside the hall containing the posters and exhibits at last month's Geological Society of America meeting in Denver, Colorado, was a surprise. A travelling photography exhibition displayed large, black-and-white portraits of women — wearing beards. Show More Summary
Kilauea may be best known for its picturesque red lava flowing into the ocean, but new research presented this week at the Geological Society of America annual meeting in Denver, Colo., suggests that locally, the volcano may be known for something more dangerous: asthma. Show More Summary
