  • CBC Quirks & Quarks On Potential Tool Usage By Australopithecus

    CBC Quirks & Quarks On Potential Tool Usage By Australopithecus

    Quirks & Quarks has a story in their January 24th, 2015 podcast on Australopithecus africanus and potential tool usage.  By studing the structure of hand bones, it has been determined that A. africanus had sufficient grip strength to use tools.  The study looked at the structure of the inner trabecular bone. The earliest known use of stone tools is from 2.6 million years ago. They were made by a species of hominin known as Homo habilis. Making stone tools and using them is only possible with the capability to make a precision grip with an opposable thumb. Human hands have that…

  • CBS Sunday Morning has a story about Stonehenge

    CBS Sunday Morning has a story about Stonehenge

    On CBS Sunday Morning today (January 25th, 2015), there is a story about the archaeological work which is working to discover the secrets of Stonehenge.  The story discusses newer techniques using underground imaging to reveal never before seen details of what Stonehendge was back when it was built.  These techniques have shown the positions of missing parts of the monument and long buried locations and features in the surrounding countryside.  The Smithonian Channel has a documentary that is the basis of this report. And they’re being looked at in a way that’s never been possible before, using high definition, ground-penetrating…

  • The Lizzadro Museum has “Dinosaurs at the Museum” on Saturday, January 24th

    Rob Sula will be speaking at the Lizzadro Museum this Saturday, January 24th, 2015.  His talk is titled "Form Follows Function: Interpreting Dinosaurs Through Their Anatomy".  With many years of field experience, Rob is a very interesting speaker! Dinosaurs have captured our collective imagination since Sir Richard Owen first described them in 1842. Their great size alone makes them unique in the history of terrestrial vertebrates. But their bones raise many questions. What did they look like? Were they fast or slow? How did they feed? How did they defend themselves? Using actual fossils, field paleontologist, Rob Sula will interpret…

  • Rods and Cones Preserved in 300 Million Year Old Fish Eye

    Rods and Cones Preserved in 300 Million Year Old Fish Eye

    Fossilized rods and cones have been found in a 300 million year old fish, according to a paper published in the December 23rd, 2014 issue of Nature Communications.  The photoreceptors were discovered using a scanning electron microscope.  The fish, Acanthodes bridgei was found in the Hamilton Quarry in Kansas, which was a shallow lagoon in the Pennsylvannian.  Because there were both rods and cones suggests that fish have been seeing in color for 300 million years.  Gengo Tanaka of Kumamoto University in Japan, the lead author, said fossils from this quarry are very well preserved because they were buried very…

  • Quirks and Quarks: When Life Crawled Out of the Sea

    Quirks and Quarks: When Life Crawled Out of the Sea

    This week’s CBC Quirks & Quarks has a story about some of the oldest aquatic scorpions.  They are about 430 to 433 million years old and from the Bruce Peninsula in Ontario.  From the structure of their feet, scientists believe they may have emerged from the water to moult, probably to avoid predators at a very vulnerable time.  During the Silurian, there was very little life on land and what was there was very simple. The first specimens of the new scorpion species Eramoscorpius brucensis were discovered in landscaping stone in people’s backyards and patios. The rocks were quarried in…

  • Avian Genomics Project

    Birds are the only surviving dinosaurs on our planet.  By 2010, only three bird species (chicken, turkey, and zebra finch) had had their genome sequenced.  The Avian Genomics Project selected 45 additional species for sequencing.  These new species represent all 32 neognath and two of the five palaeognath orders.  This allowed for a large-scale phylogenomics analysis to investigate the bird family tree, and applied comparative genomics methods to address various questions such as avian genome evolution, sex chromosome evolution, molecular basis of flight, loss of teeth, vocal learning, and endangered birds.  In addition, while consuming this large body of data, new…

  • Open Access Dinosaurs

    Andy Farke has a nice article about open access science at opensouce.com.  His article lists the 36 (nearly 1 a week!) new dinosaurs described in 2014.  Of these 36, 17 were published in open access or free-to-read journals.  That’s not much change from 2013’s 38 new and 16 free to read.  It is, however, a better percentage.  We’ll leave it to the reader to check for statistical significance. PLOS ONE continues to dominate the world of open access dinosaur species—nine of those 17 were published there. I will be very interested to see if this trend continues into future years, particularly…

  • Mastodon Bones Found in Michigan Backyard

    Mastodon Bones Found in Michigan Backyard

    When we say we enjoy finding fossils in our own backyard, we are usually speaking metaphorically.  Eric Witcke means it literally.  He and neighbor Daniel LaPoint were excavating a backyard pond at his home in Bellevue Township, Michigan, when they unearthed a paleontological treasure.  They called in the some experts from the University of Michigan’s Museum of Paleontology and were told the 42 odd bones belonged to a 37 year old male Mastodon.  The Mastodon lived between 10,000 and 14,000 year ago. Daniel Fisher, the director of the U of M museum, has made two trips to confirm and examine…

  • It’s Not Nessie, But Jurassic Predator Found In Scotland

    It’s Not Nessie, But Jurassic Predator Found In Scotland

    A new Ichthyosaur has been described in the Scottish Journal of Geology.  Described as looking like a “sinister dolphin”, it was 14 foot long and lived about 170 million years ago.  It’s name is Dearcmbara shawcrossi, which is pronounced ‘jark vara’.  The name means “marine lizard” in Scottish Gaelic.  The species name is for the discoverer Brian Shawcross.  It’s bones were discovered in the late 1950s on Scotland’s Isle of Skye. “During the time of dinosaurs, the waters of Scotland were prowled by big reptiles the size of motor boats,” Dr Steve Brusatte, of the University of Edinburgh’s School of…

  • (broken link) Utah’s Dinosaur ‘Death Trap’ Reveals Trove of Giant Predators

    National Geographic has a story about the discovery of a Jurassic aged predator trap that is  finally heading into the lab for study.   The remains, probably a bed of quicksand, were discovered about 10 years ago in Utah.  After years of work, a group of paleontologists have finally gotten the huge block of stone and bones down off the mesa where it was discovered.  There’s an interesting video that shows how they got the chunk of sandstone onto the truck.  The fossils include a prey animal skeleton, an Iguanadon, along with up to 10 specimens of Utahraptor.  The preservation is…

  • Enormous Underwater Fossil Lemur Graveyard Found

    Here’s a story about an enormous underwater fossil lemur graveyard.  There’s a video that shows the remains of 1000 year old skeletons. Anthropologists and paleontologists uncovered what could be the largest single collection of lemur remains ever found. The remains were hidden in a series of underwater caves in a remote desert region of Madagascar. Described as a “lemur graveyard,” the discovery of hundreds of potentially 1,000-year-old skeletons make it one of the most unique animal gravesites in the world. This discovery could be important for understanding animal and human ancestry, and result in a new era for underwater paleontology.

  • Fracking in Ohio confirmed as cause of rare earthquake strong enough to be felt

    A new study links the March 2014 earthquakes in Poland Township, OH to hydraulic fracturing.  The fracking activated a previously unknown fault.  The quake had a magnitude of 3.0.  The study was published online by the Bulletin of the Seismological Society of America (BSSA). In March 2014, a series of five recorded earthquakes, ranging from magnitude 2.1 to 3.0, occurred within one kilometer (0.6 miles) of a group of oil and gas wells operated by Hilcorp Energy, which was conducting active hydraulic fracturing operations at the time. Due to the proximity of a magnitude 3.0 event near a well, the Ohio…

  • Oldest horned dinosaur species in North America found in Montana: Hooked beak, sharply pointed cheeks distinguishes neoceratopsian species

    Interesting story over at ScienceDaily.  The oldest known horned dinosaur has been found in Montana. The limited fossil record for neoceratopsian–or horned dinosaurs–from the Early Cretaceous in North America restricts scientists’ ability to reconstruct the early evolution of this group. The authors of this study have discovered a dinosaur skull in Montana that represents the first horned dinosaur from the North American Early Cretaceous that they can identify to the species level. The authors named the dinosaur Aquilops americanus, which exhibits definitive neoceratopsian features and is closely related to similar species in Asia. The skull is comparatively small, measuring 84 mm…
