  • Fossil Friday #322: Macroneuropteris scheuchzeri from Dresden
    For this week’s Fossil Friday, we have a very nice Macroneuropteris scheuchzeri (see Mazon Monday #39). Macroneuropteris scheuchzeri is a fairly common seed fern, which is found in many Carboniferous fossil deposits. In some Mazon Creek localities like the Mazon River, it’s a dominant component of the flora. It was called Neuropteris scheuchzeri until 1977, when the classification was changed by Robert Gastaldo after extensive studies on European examples that looked at its frond architecture and cuticle.

  • 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…

  • Mysterious Spheres on Mars

    Via AFP: NASA’s Opportunity rover, older brother to the Curiosity rover that landed on Mars last month, has made a new discovery that geologists find both puzzling and exciting, the US space agency said Friday. Opportunity, which has been on the Red Planet since 2004, has come across an outcrop of tiny spheres — up to around an eighth of an inch (three millimeters) in diameter — the likes of which scientists have never seen before.

  • New Way of Thinking About Ocean Currents

    Via PhysOrg:   … Here’s how it works: Basically, the oceans, together with the atmosphere, rebalance heat on the planet. The sun shines on the Earth and heats up the tropics more than the poles. Near the poles, the ocean is cold and the water sinks; near the equator, the surface of the ocean is inviting and warm—and floats on top of the colder deep water. So the question is this: Where does the water that goes down come back up? Speer, Marshall and other oceanographers now believe that it comes back up in the Southern Ocean surrounding Antarctica—not as…
