  • Fossil Friday #321: A Large Crenulopteris acadica from the Mazon River
    Marie Angkuw sent us these photos of a beautiful Mazon Creek fern. It’s a Crenulopteris acadica from the Mazon River. Crenulopteris acadica is a common fern from Mazon Creek, but this one is very large with multiple fronds. Marie collected this one a few years ago at the I&M Canal Corridor Benefit. The concretion opened up via the Freeze/Thaw method this past winter.

  • XRaying for Diamonds

    Via Gizmodo: “… The new process actually involves blasting chunks of kimberlite ore—where diamonds are most often found—a couple of times with X-rays from two different spectrums. This produces two distinct images of the same area that are then analyzed using a special algorithm developed by the EZRT. The newly developed technique is able to accurately spot diamonds buried in a piece of ore as small as just a few millimeters in length….

  • Carbon Hill Historical Museum Open House, 4/27

    Michele Micetich sent this invitation a few days ago: Hello, I am the president of our historical society here in Carbon Hill, IL, just outside Coal City. We often have fossil collectors visit our little museum, the Carbon Hill School Museum, where we have much information on coal, fossils, immigrants, and the geology and geography of our coal field area in Will and Grundy counties. We hold several events throughout the year. A few ESCONI members have visited us for the fossil events. We keep Jack Wittry’s books as well as the older books by Richardson and Langford on hand for…

  • Ice Age Bees from LaBrea

    Via Science News:     It’s not all mammoths and saber-toothed tigers. The first leafcutter bees from the Pleistocene epoch have turned up in the La Brea Tar Pits in Los Angeles. Exquisitely preserved as pupae undergoing their transformation to adulthood, a male and a female are still wrapped in their leafy nest. Micro-CT scans and other clues let researchers identify the bees as Megachile gentilis, a species that still lives today. These bees line burrows with bits of leaves to pamper developing offspring….

  • How To Drill Oil in North Sea

    Via Atlantic: http://www.theatlantic.com/technology/archive/2014/04/how-to-drill-for-oil-in-the-brutal-conditions-of-the-north-sea/360262/ Maersk already has six rigs in the region, according to this company-produced video about “Life as a driller in the North Sea.” The employee featured here, Chris Hallan, has worked on the Innovator for nine years and will move to the Intrepid this spring. http://www.theatlantic.com/technology/archive/2014/04/how-to-drill-for-oil-in-the-brutal-conditions-of-the-north-sea/360262/_http://www.theatlantic.com/technology/archive/2014/04/how-to-drill-for-oil-in-the-brutal-conditions-of-the-north-sea/360262/

  • Extra eyes on ancestors of Harvestmen

    Via Wired: Harvestmen (also known as daddy long legs) aren’t spiders, and if you could (or wanted to) lean close enough, you’d be able to see one of the few physical features that distinguish them from their arachnid cousins. It’s in the eyes: Spiders usually have 6 or more, but the harvestman has only one set, tightly clustered on the top of its head, making it look like a cyclops. However, scientists report today in the journal Current Biology that the ancestors of modern harvestmen had an extra pair, called median eyes, located on either side of the front of their heads.

  • Archaeology Study Group Meeting Report: Shroud of Turin

    Archaeology Study Group Meeting Report: Shroud of Turin

    From Dr John Ruskamp: Revered by some as a religious artifact and rejected by others as a medieval fake, the Shroud of Turin is both a historic and scientific enigma. Indeed!  However, for the members of ESCONI’s Archaeology group the scientific facts related to this artifact are now clear. In a presentation by member John Ruskamp, those in attendance at last month’s meeting were able to view, study, and photograph one of only a few life size replicas of the Shroud of Turin. (The original shroud is displayed only a few times a century and is kept in Turin, Italy.)…

  • Footprints of Dino Chase

    Via ScienceNews: …  Footprints of a T. rex-type dinosaur chasing an Apatosaurus-like animal have been turned into a 3-D fly-through, giving researchers a way to verify maps of the tracks drawn 70 years ago. The tracks, from the Paluxy River in Texas, are among the most famous dinosaur footprints in the world. But the pathway has been under threat since paleontologists excavated, divided and moved some of the prints to museums, and others have been lost.

  • Rumor Control

    There’s a video going around that shows a long line of bison trotting down a road in Wyoming’s Yellowstone National Park. Some people are pointing to this as a sign that the animals are hightailing it out of the park because the Yellowstone volcano is about to blow its top. But in the video above, Yellowstone Park Public Affairs Chief Al Nash explains that the bison and other animals are simply migrating to a lower elevation where they can find food, which they do every year in the dead of winter.

  • Furniture made from minerals need not say “Flintstones”

    Via the NewYork Times: … At the Evolution Store, the designers admired a large chunk of polished petrified wood — part of an ancient tree that had fossilized to stone — noting that it would make an appealing (if heavy) stool. As Mr. Buntain said, “It’s a nice object because it’s quiet but has an incredible history.” And its coloring, he added, made it look “almost like bone or horn.” For those in search of something even more primitive-looking, the pair suggested the Delaware Bluestone chair by Max Lamb at Johnson Trading Gallery. “It’s just a raw piece of stone,”…

  • Via Reuters, written by Will Dunham: Methane-spewing microbe blamed in Earth’s worst mass extinction “One important point is that the natural environment is sensitive to the evolution of microbial life,” said Daniel Rothman, an MIT geophysics professor who led the study published in the journal Proceedings of the National Academy of Sciences.

    Luprisca incuba

    From Scientific American, Tiny, Ancient Crustacean Preserved in Fool’s Gold, Legs, Eggs and All, By Jennifer Frazer, March 27, 2014 … Incredibly, the paper describing these new fossils notes that the arrangement of some of the structures on the first antenna is the same as that of the group of living ostracods they are hypothesized to have belonged to, “even down to the tiny ventral seta and two long distal setae.” That such details could remain unchanged over 450 million years is, in my opinion, mind-boggling….   Image: Have Shell, Will Travel.

  • What is a disaster blog?

    The Charlotte Observer tells us: Cataclysms and catastrophes: If something in nature explodes, collapses or crashes, you can probably read about it in Geology in Motion ( www.geologyinmotion.com), a blog by Susan Kieffer, emerita professor of geology at the University of Illinois at Champaign-Urbana. Q. You’ve written a book on the science of natural disasters, and your blog covers such terrifying events as car-swallowing sinkholes and erupting volcanoes. To what degree has science “tamed” disasters by providing data to warn people in advance?….
