  • Spider Kills Wasp a 100 Million Years Ago

    Spider Kills Wasp a 100 Million Years Ago

    From Sci-News: (hat tip via Dave at ESCONI Yahoo Group) This piece of amber preserved the event in remarkable detail, an action that took place some 100 million years ago in the Hukawng Valley of Myanmar. The fossil also contains the body of a male spider in the same web. This provides the oldest evidence of social behavior in spiders, which still exists in some species but is fairly rare. Most spiders have solitary, often cannibalistic lives, and males will not hesitate to attack immature species in the same web. “This juvenile spider was going to make a meal out of…

  • Chinese Sculpture From Meteorite

    From Wiley via geology.com: The Chinga meteorite fell near the border of what is now Siberia and Mongolia at least 10,000 years ago. Researchers have recently linked a 10.6 kilogram sculpture to the meteorite through geochemical testing and to a culture of the eleventh century located in the fall area through ethnological analysis. Interesting even if you think it is somewhat speculative.

  • Talk by Alan Hodgkinson On Gemstone Identification

    Hat tip D. Lovely! October 15, 2012 6:00 pm  Jewelers Center 18th Fl.  5 So. Wabash Ave.  Chicago, Illinois   Today, often sophisticated equipment is needed in the identification of gemstones and diamonds. One of the most underused and misused pieces of equipment is the polariscope. In this enlightening presentation, renowned Scottish gemologist, Alan Hodgkinson, will demonstrate “Pushing  the Polariscope” for ease of determining optic figures, identifying gemstones, distinguishing spectrums, and determining diamond type. Learn to use the polariscope in ways GIA did not teach you.   RSVP Today to:  Heidi Harders Email Heidi click here $40.00 includes light dinner…

  • I See Dead People

    From TED Video Blogs: Bioarcheology is a fairly new field — a subset of anthropology which combines biological anthropology and archeology. It’s the use of biological techniques to look at archeological human skeletons. What bioarcheology does is help recreate lives by examining human remains for clues to what they ate, what they did for work, what illnesses they may have had, what traumas they suffered, how tall they were, whether they were a man or a woman, and their age. .

    Writeup About the June Archaeology Field Trip

    Archaeology June Field Trip On June 2nd and 3rd, we had an Archaeology field trip to see Cahokia Mounds, the Museum of Westward Expansion, the Saint Louis Arch, and the Lewis and Clark Memorial State Park.  Cahokia Mounds offers a World-Class Interpretive Center with museum exhibit galleries, an orientation show theater, a museum shop and a courtyard for educational programs. Outdoors you’ll find self-guided tours, guided tours, trails and Monks Mound, the largest earthwork in North America. After viewing the orientation video in the Interpretive Center, we walked around looking at exhibits which explained how the people lived and what…

  • Methane Beneath Antarctic

    Via University of California Santa Cruz:: (hat tip Geology.com) … “It is easy to forget that before 35 million years ago, when the current period of Antarctic glaciations started, this continent was teeming with life,” Tulaczyk said. “Some of the organic material produced by this life became trapped in sediments, which then were cut off from the rest of the world when the ice sheet grew. Our modeling shows that over millions of years, microbes may have turned this old organic carbon into methane.”

  • New Finds in Burgess Shale in Canada

    Via The Star.com: Jean-Bernard Caron, curator of invertebrate paleontology at the Royal Ontario Museum, spent seven weeks this summer leading a team on an exploration of the Burgess Shale sites in Yoho National Park in British Columbia. The best-known site is the Walcott Quarry, where there was a major discovery of well-preserved, soft-bodied fossils in 1909. The team found a new site in Kootenay National Park, at a location Caron isn’t ready to reveal yet, with “very rich fossil deposits” from new and existing species. It could be comparable to the original site, said Caron.

  • A new study suggests widespread land-based microbial life in the Archean Era

    Via Sci-News: (Hat tip Dave Carlson at the ESCONI Yahoo Group): Scientists at the University of Washington suggest that early microbes might have been widespread on land, producing oxygen and weathering pyrite, an iron sulfide mineral, which released sulfur and molybdenum into the oceans.

  • Lepidopteris baodensis sp.

    From PhysOrg: Recently, a mysterious seed fern, Lepidopteris baodensis sp. nov., dating to more than 251 million years ago (Ma), was discovered at the Baijiagou of Baode, Shanxi, China, from the Upper Permian Sunjiagou Formation. This discovery completely changed the understanding of the stratigraphic distribution of the genus Lepidopteris in China and promoted the taxonomic study of late Paleozoic plants.

  • Interview with Author of “The Rocks Don’t Lie”

    From Seattle Times:  An interview with the author of “The Rocks Don’t Lie: A Geologist Investigates Noah’s Flood,” MacArthur Fellow and UW professor David Montgomery….  Q: Most people probably think creationism is a pretty old belief system, but in the book you clearly lay out that it’s not. Briefly describe how it developed. A: George McCready Price was the guy who championed flood geology (the theory that Noah’s flood was real) in its darkest hours through the early 20th century. He was not a trained geologist, but he argued that geologists had the whole theory wrong. His arguments evolved into…

  • Radio Interview on Human Relation – the Denisovans

    Via Science Friday:  Reporting in Science, researchers write of sequencing the genome of a young Denisovan girl — an archaic human distantly related to Neanderthals and modern humans. Geneticist David Reich discusses the tale the genome tells about the Denisovan people and their interactions with modern humans.

  • Fate of Pumice Rafts

    Fate of Pumice Rafts

    Via Wired: The NASA Earth Observatory has been doing an excellent job tracking the spread of the pumice from the Havre eruption in the Kermadec Islands. Currently the pumice is spread over an area of 270,000 km2 / 100,000 sq. miles of the Pacific Ocean and is continuing to spread (see above). This pumice will likely stay afloat for months if not longer and eventually make landfall wherever the currents dictate – potentially as far off as South America. Pumice rafts are not particularly uncommon (see map below), especially in areas of abundant submarine volcanism like the southwestern Pacific Ocean, and…
