  • Moon Rock, Not

    Via AP: “…The Dutch national museum said Thursday that one of its prized possessions, a rock supposedly brought back from the moon by U.S. astronauts, is just a piece of petrified wood. Rijksmuseum spokeswoman Xandra van Gelder, who oversaw the investigation that proved the piece was a fake, said the museum will keep it anyway as a curiosity….”

  • Science Friday Has 2 Earth Science Interviews

    Science Friday, a weekly radio show about science, provided two interesting interviews this week for those interested in the earth sciences: University of Chicago paleontologist Paul Sereno talks about the new tiny T-Rex.  Abstract available here. (Photo: Paul Serano via Science Friday.) Don Brownlee, Principal Investigator, NASA’s Stardust Mission and Professor, Department of Astronomy, University of Washington Seattle, Washington talks about samples of comet dust that were returned to Earth embedded in aerogel contained the amino acid glycine, with an isotopic signature that indicates it was not formed on Earth.

  • African Rockhounds

    African Rockhounds

    Betsy and I have been members of our local rock club since 1977. The Earth Science Club Of Northern Illinois, ESCONI, played a large role in our family’s lives as the older members shared their finds and their knowledge with Becky and Lisa as they grew into young ladies. So it should come as no surprise that we joined a club in Cape Town this year. The Cape Town Gem and Mineral Club has a narrower scope than ESCONI, focusing on minerals and lapidary. They are quite active, holding monthly sales, swaps, programs and barbeques as well as the occasional…

  • Report that NPS Has Fewer Geologists

    Arizona Geology posts about an interesting issue (via geology.com): … The NPS [National Park Service] Geologic Resources Division was not established until the late 1990s and instead of growing, they are shrinking. They are now at 20 people, down 9 in the past few years. Most parks that were designated so because of their geologic attributes do not even have a single geologist on staff. Compare this to something like 800 biologists in the NPS….

    Paleontology Meeting, Sat, 9/19 – Mazon Creek Jellyfish

    Paleontology Meeting, 7:30 pm, College of Dupage, Building K – Rm 131. On September 19th, the Paleo study group will begin examining Mazon jelly fish. So bring your Mazon Creek jellyfish – some may be photographed for the new book. Then, on October 17th, the Paleo study group will cover the worms. ESCONI is creating a new Mazon fauna book. Each paleo meeting will be a time for specimens to be photographed for possible inclusion in the new book. So examine your Mazon Creek collections over the next few months and consider any possibilities you may have to contribute to…

    Jack Wittry Presents at the General Meeting on 9-11-09, by Andrew Young

         There was certainly a back-to-school atmosphere at the General Meeting last Friday, with attending members full of stories and finds after the club’s summer recess. As people paraded into the classroom, many had cardboard trays, specimen cases or plastic bags carrying carefully split fossil concretions pertaining to that evening’s lecture topic. After some special announcements, Jack Wittry, author of the beautiful and informative book entitled, The Mason Creek Fossil Flora, presented a standing-room only talk on his specialty. Not only was his delivery and organization clear – making sense of the, often time, fragmented evidence of the fossil record…

    Rock Slide Site

    Rock slide site, rock slide site, sock rock lite… (just try to say Rock Slide Site three times and get it right.)

  • Micro Meeting Cracks Geodes

    Micro Meeting Cracks Geodes

    Saturday night the Micromineral groups was busy cracking geodes using a pipe cutter. This method worked well because the pipe cutter cut the geode into two halves – instead of many pieces. Many of the geodes fluoresced – mostly the Mexican geode brought by Kathy. (see below)

  • MicroRNA Used to Track Evolution to Fossils

    Via Science News:  …. The team’s microRNA sequencing results also agree with the order in which the different annelids and their relatives appear in the fossil record—something that previous hypotheses about their relationships had failed to do, said co-author Derek Briggs, Yale’s Frederick William Beinecke Professor of Geology and Geophysics. “This study is an elegant example of how new methods can reconcile results from molecular sequencing of living animals with information from the fossil record,” he said…

  • Largest Crystals in the World

    Largest Crystals in the World

    Description of exploration of the Crystal Cave of Giants. The explorer, George Kourounis, has other photo galleries as well. From the site: … The crystals themselves are made of selenite which is crystallized gypsum, the same material used in drywall construction. Except these crystals formed over a span of about half a million years in a hot water solution, saturated with minerals. The the temperature inside the cave remained very consistently hot for the entire time the crystals were growing.…

  • 10 Extraordinary Lakes

    From Womans Day via geology.com: When a body of water is inland, not part of an ocean, deeper than a pond and fed by a river, it is classified as a lake. Usually created by rifts, tectonic shifts and ongoing glaciations—often found in basins or along mature rivers—they’re some of the most beautiful nature-… Photo: Plitvice Lake by 29cm
