Stretching the truth: vertical exaggeration of seismic data

by Zoltan Sylvester in Hindered Settling

If someone showed a photograph of the famous Cuernos massif (Torres del Paine National Park, Chile) like the one below, it would be - probably, hopefully - obvious to everybody that something is wrong with the picture. Our eyes and brains have seen enough mountain scenery that we intuitively know how steep is 'steep' in alpine landscapes. The peaks in this photograph just look too extreme, too high if one takes into account their lateral extent.The Cuernos in Torres del Paine National Park, Chil........ Read more »

Whale Bone-Devouring Worm Into More Than Just Whales

by Kevin Zelnio in Deep Sea News

We have a long history of being HUGE fans of the “bone-devouring zombie worm from hell”. Osedax species were described less than 10 years ago and much work on their reproduction, evolution and ecology has yielded incredible insights into a unique and bizarre way of life! Early on, Osedax was only found on . . . → Read More: Whale Bone-Devouring Worm Into More Than Just Whales... Read more »

Citing versioned papers, robots and reviewers?

by Daniel Mietchen in Research Cycle Research

Established scholarly citation practices are tailored towards static documents. With the use of versioned documents spreading, citation formats have to follow suit. This requires to balance the need for proper identification of the source of a claim with the demands for cited information being up to date. Getting this right is particularly important in naturally versioned environments like wikis or GitHub. Continue reading →... Read more »

Mountain Dwarfs & Earthquakes

by Cris Campbell in Genealogy of Religion

Before there were materialist explanations of nature’s unpredictable fury, there were stories. These stories were not mere entertainment, but were attempts to make sense of that which was inexplicable. The world is of course an unpredictable place. We were powerfully reminded of this but one month ago, as an earthquake and tsunami devastated Japan.
Modern Japanese [...]... Read more »

Birds Inherited Strong Sense of Smell From Dinosaurs

by Brian Switek in Dinosaur Tracking

http://www.youtube.com/watch?v=22Qup626DTc Feathers, air sacs, nesting behavior—the earliest birds owed a lot to their dinosaurian ancestors. The first birds also inherited a strong sense of smell. Modern birds have not been thought of as excellent scent-detectors, save for some super-smellers such as turkey vultures, which detect the scent of rotting carcasses. We typically think of avians [...]... Read more »

Structural geology in Cabo Peñas (Asturias, Spain). Part I

by Jorge in StructuralGeology.org

The NW of the Iberian Peninsula is a remanent of the doubly vergent Hercynian Orogen (see figure attached), formed during the Devonian-Carboniferous time by the collision of Laurussia (or Euramerica) with Gondwana, forming Pangaea.
In this article I want to show you some pictures we did in the Bay of Llumeres.... Read more »

Daemonosaurus Shakes Up the Early History of Dinosaurs

by Brian Switek in Dinosaur Tracking

Evolution is not a constant march of onward-and-upward progress. Any organism is a mosaic of the ancient and the modern—old features can be modified and put to new uses over time—and the mechanism of natural selection accounts for both an apparent lack of change and dramatic evolutionary transformations. There is no driving force towards perfection, [...]... Read more »

The Deep History of Dinosaur Lice

by Brian Switek in Dinosaur Tracking

Hunting dinosaurs is a dangerous business. Scores of fictional, time-traveling hunters have learned this lesson the hard way, but arguably the most unfortunate was the protagonist of Brian Aldiss’ short story “Poor Little Warrior.” All Claude Ford wanted to do was get away from his disappointing life and unhappy marriage by gunning down prehistoric monsters.

Another Use For Shovel Tusks

by Laelaps in Laelaps

Author’s Note: I’m a little too short on time to finish up a new post for this afternoon, so here’s a revised essay from the archives that is a fitting follow-up to Saturday’s post on American mastodon tusks.
Whenever I visit  New York’s American Museum of Natural History, I can’t leave without briefly passing through the [...]... Read more »

How to Build a Dinosaur Den

by Brian Switek in Dinosaur Tracking

Oryctodromeus isn’t exactly a household name. A small, herbivorous ornithopod found in the Late Cretaceous rock of western North America, it was the sort of dinosaur most often depicted as being prey for charismatic carnivores. But there was at least one aspect of Oryctodromeus that made it particularly interesting—this dinosaur may have lived in burrows. [...]... Read more »

The Meaning of Mastodon Tusks

by Laelaps in Laelaps


Until recently, I did not fully appreciate fossil teeth. Their significance for identifying species and narrowing down the general diet of extinct animals was obvious, but I didn’t understand that teeth also hold intricate records of an individual animal’s life. Tiny pits and scratches on enamel can reveal what a creature was eating around the [...]... Read more »

Life After Death At Yellowstone: An Interview with Josh Miller

by Andrew Farke in The Open Source Paleontologist

In my last post, I introduced a ground-breaking study recently published in PLoS ONE, that shows how we can infer long-term trends in animal populations just from their bones. This work has big implications for ecology, conservation, and public policy, and is also a really neat piece of science. For this post, I talked to the author of the study, Josh Miller, about his work and some of the tidbits that didn't make it into the paper.Yellowstone NP gets a lot of visitors, and you surely must have ........

Life After Death at Yellowstone

by Andrew Farke in The Open Source Paleontologist

Taphonomy - the study of what happens to an organism after it dies - is integral to reconstructing the past. Perhaps the most important lessons come in inferring ecological interactions. Did that group of animals live and die together, or were they jumbled long after death? Were all of those shark teeth with the plesiosaur bones from a feeding frenzy, or just a fluke of currents? How closely does a set of fossils represent the relative abundance of the different species in the quarry? Such examp........ Read more »

The Last Resting Place of Decuriasuchus

by Laelaps in Laelaps

While making the rounds promoting his new book Boneheads, art dealer and author Richard Polsky stopped by NPR last Sunday to talk about his personal quest to find a Tyrannosaurus rex. The romance of what paleontologist Bob Bakker has called “the big game hunt in Deep Time” drew him in. Having a pet Tyrannosaurus is [...]... Read more »

Is the current plan for seeking evidence of life on Europa on this ice?

by Greg Laden in Greg Laden's Blog

Europa is a moon of Jupiter, the smallest of the four Jovian moons discovered by Galileo in 1610. Juipter has 63 objects circling it that are called moons, though only eight of them are "regular" in their orbit and other characteristics. The rest are bits and pieces of clumped up matter that were probably captured by Jupiter's big-ass gravitational field, and have irregular orbits, i.e., they go the wrong-way around the planet, or are not in the solar plane, etc. Read the rest of this post... ........

A New Giant Tyrant, Zhuchengtyrannus

by Brian Switek in Dinosaur Tracking

“While 2010 was celebrated as the year of ceratopsians by many,” paleontologist Dave Hone wrote at Archosaur Musings yesterday, “it should not be overlooked the huge number of tyrannosaurs that have cropped up in the last year or so.” He’s right. For a long time Albertosaurus, Gorgosaurus, Daspletosaurus, Tarbosaurus and, of course, Tyrannosaurus made up [...]... Read more »
