  • Fossil Friday #311: Dung Beetle Balls from the Oligocene
    Today’s contribution comes from our old friend Ralph Jewell. Back in the 1990s, Ralph was interested in the Oligocene fossils of the Brule Formation, which dates to 34-40 million years ago. This region is sometimes referred to as the White River as the Brule Formation is a member of the White River Group.

  • Mine Shafts for Geothermal Energy

    Mine shafts on the point of being closed down could be used to provide geothermal energy to local towns. This is the conclusion of two engineers from the University of Oviedo, whose research is being published this month in the journal Renewable Energy….  As reported by AlphaGaileo via geology.com.

  • Copper Country Mineral Retreat

    Copper Country Mineral Retreat

    Last week, Garrison Keillor said Lutherans go on vacation to become better people – not for pleasure. It is so for me – I was brought up Lutheran. So I’m back from our family vacation from Houghton, Michigan and the Copper Country Mineral Retreat and I’ve came back vowing to be a better person – e.g., train my dog (another story), inventory new rocks (instead of letting them sit in the garage) and move to Houghton, MI to work at Fiber Whims. It was a bonus that the vacation in Keweenaw was a pleasure. I fell in love with the…

  • Zanno, Field Museum, Nothronychus graffami in News

    MSNBC… A multi-institutional team of scientists this week reports the discovery of a giant new dinosaur in Utah, Nothronychus graffami, which stood 13 feet tall and had nine-inch-long hand claws that looked like scythes. Its skeleton, described in the current issue of Proceedings of the Royal Society B, represents the most complete remains ever excavated of a therizinosaur, meaning "reaper lizard." It is one of only three such dinosaurs ever found in North America. Lead author Lindsay Zanno told Discovery News that therizinosaurs, including the new Utah species, "are unusual in that they have small heads with a keratinous beak…

  • Grandmothers Find Gold

    Via New York Times: Sweden….Berry picking is a serious business to Mrs. Wiik (pronounced VEEK), who was born in this village of 171, and her friend, Harriet Svensson, 69. For 40 years the two, widows with children and grandchildren, have explored every patch of field and forest clearing in the region, hunting for mushrooms and wild berries — blueberries, raspberries, blackberries, cloudberries. But the women are also amateur geologists. They never leave home for a stroll in forests or fields without their geologists’ hammers, with their 30-inch handles, and their magnifying eyepieces, dangling from ribbons around their necks. So in…

  • Platinum Inclusions in Diamonds

    From Geology.com: …journal Nature, researchers from the Carnegie Institution and the University of Cape Town presented their findings after studying 2 billion year-old diamonds mined near the famed Bushveld Complex, a unique and mysterious geological formation in central South Africa. After analyzing mineral inclusions within the diamonds, the researchers believe both the diamonds and the magmas that gave rise to the Bushveld Complex have an ancient subcontinental mantle source… Illustration Credit: Zina Deretsky, National Science Foundation.

  • Greening Led to Cambrian Explosion

    Via ScienceNews: …While scientists can pinpoint this pivotal period as leading to life as we know it today, it is not completely understood what caused the Cambrian explosion of life. Now, researchers led by Arizona State University geologist L. Paul Knauth believe they have found the trigger for the Cambrian explosion. It was a massive greening of the planet by non-vascular plants, or primitive ground huggers, as Knauth calls them. This period, roughly 700 million years ago virtually set the table for the later explosion of life through the development of early soil that sequestered carbon, led to the build…

  • Metal Miners Paid Better Than Other Miners

    Via InfoMiner: … Workers at U.S. metal mines take home larger paychecks and enjoy more benefits than those at U.S. aggregate and construction materials mines, according to a study by CostMine. The study also found that paychecks were 29% higher on average for hourly workers at the metal mines and 35% higher for salaried workers. The disparity persisted throughout all the job categories with the single exception of environmental coordinators who earn about 5% more on average at aggregate operations.   Not only are paychecks higher at metal mines, but benefits are more generous as well. Workers at metal mines enjoy…

  • (broken link) Dino Hunter Gets Probation

    From AP: …Renowned dinosaur hunter Nathan Murphy was sentenced Wednesday to four months in a halfway house and three years probation after pleading guilty to stealing fossils. Murphy was accused of stealing 13 dinosaur bones from central Montana’s Hell Creek badlands in 2006. He pleaded guilty in April to theft of government property. U.S. District Judge Sam Haddon also sentenced him to 300 hours of community service and ordered him to pay $17,325 in restitution…

  • Neanderthal Fossil From North Sea

    Neanderthal Fossil From North Sea

    From BBC via Geology.com: Part of a Neanderthal man’s skull has been dredged up from the North Sea, in the first confirmed find of its kind. …. Scientists in Leiden, in the Netherlands, have unveiled the specimen – a fragment from the front of a skull belonging to a young adult male. Analysis of chemical “isotopes” in the 60,000-year-old fossil suggest a carnivorous diet, matching results from other Neanderthal specimens. The North Sea is one of the world’s richest areas for mammal fossils. But the remains of ancient humans are scarce; this is the first known specimen to have been…

    Via Geology.com from Science News: Scientists are decoding the geological secrets of banded iron formations, By Sid Perkins: …. BIFs, as they’re known to geologists, are enigmatic. All seem to have started out as sediments on ancient seafloors, and by some estimates the oxide mineral accumulated in all known BIFs contains about 20 times as much oxygen as today’s atmosphere does. Yet some of these deposits accumulated long before Earth’s atmosphere became thoroughly oxygenated, so the source of the oxygen stored in these BIFs is baffling…. Discussion of various theories old and new. (Image courtesy Earth Science World Image Bank, Copyright ©…

    Boy Hit By Meteorite

    German boy sees light, feels burn as pea sized meteorite bounces off his hand, gets knocked down, stands up and sees foot wide crater next to him… he couldn’t hear so well for awhile but lives to tell about it…. Update: It may be a hoax… the Bad Astronomy blog argues both ways and some of the comments are informative too.
