Nodosaur fossil so well-preserved it boggles minds

A dinosaur fossil that was discovered in a bitumen pit in Alberta, Canada, in 2011 is the best-preserved specimen of a nodosaur ever discovered, and it is truly a spectacle to behold. The herbivore died between 110 and 112 million years ago in a riverbed and was swept to sea where it was swiftly buried in the mud and sediment of the seabed. Resting on its back, the nodosaur’s soft tissues, armour plating and thorny ridges became mineralized, preserving its form in stone.

Nodosaurs averaged about 18 feet in length and weighed 3,000 pounds, so they were formidable creatures, although they lacked the flashy spiked tail club their ankylosaur cousins used to break the shins of would-be predators.

They determined that it is a new species of nodosaur as well as the oldest dinosaur ever discovered in Alberta. The painstaking work of excavating the mineralized beast from the surrounding rock has been visible to the public through the lab gallery window since its discovery.

Photographer Robert Clark took many exceptional photographs, and even he, who has doubtless seen many wonders as a National Geographic photographer, was dumbfounded by the preservation of the nodosaur.

Fossilized remnants of skin still cover the bumpy armor plates dotting the animal’s skull. Its right forefoot lies by its side, its five digits splayed upward. I can count the scales on its sole. Caleb Brown, a postdoctoral researcher at the museum, grins at my astonishment. “We don’t just have a skeleton,” he tells me later. “We have a dinosaur as it would have been.”

Photo by Robert Clark for National Geographic.For paleontologists the dinosaur’s amazing level of fossilization—caused by its rapid undersea burial—is as rare as winning the lottery. Usually just the bones and teeth are preserved, and only rarely do minerals replace soft tissues before they rot away. There’s also no guarantee that a fossil will keep its true-to-life shape. Feathered dinosaurs found in China, for example, were squished flat, and North America’s “mummified” duck-billed dinosaurs, among the most complete ever found, look withered and sun dried.

But after four days of working on this one—delicately scraping off samples smaller than flecks of grated Parmesan—even he is astounded. The dinosaur is so well preserved that it “might have been walking around a couple of weeks ago,” Vinther says. “I’ve never seen anything like this.”

Photo by Robert Clark for National Geographic.Some people are making Zuul comparisons, but scientists already snagged that little pop culture gem as the official name of an ankylosaur unearthed in Montana which also had spectacular soft-tissue fossilization. They called it Zuul crurivastator, meaning “Zuul, destroyer of shins,” which I think we can all agree is one of the all-time great feats of nomenclature. I think the Alberta nodosaur bears a more notable resemblance to the Gorn, of original Star Trek fame. That glaring blank eyesocket with the thorny brow ridge is so Gorny.

Nodosaur sees what you did there. Photo by Robert Clark for National Geographic.National Geographic has created a 3D virtual model of the nodosaur fossil that is one of the best I’ve ever seen. As you might expect, you can zoom in and out, turn it around and view it from different perspectives, but this one has tons of additional features. As you scroll, the parts are exploded and labeled so you can get a thorough idea of what bits go where and what function they performed. A drawing of a complete nodosaur as it would have looked in life is used to diagram what parts of it have survived in the fossil.

 

Edward Hopper in Motion

It’s the 50th anniversary of Edward Hopper’s death today. To celebrate the realist painter’s oeuvre, Orbitz (yes, the discount travel site) has created animated versions of nine of his most recognizable and iconic works.

I generally enjoy attempts to add dimension to stills or artworks, for instance the recent trend in documentaries to give a 3D effect to old photographs. A subtle animated element can be effective as long as it makes sense in the context of the scene and it isn’t just distracting. All in all, I find the Hopper animations fairly good. There are some things I’d do differently, mainly fewer short repetitive loops and more smooth continuous action. Some elements — smoke over coffee cups, flickering neon signs — look too rushed. However, Hopper’s characteristic urban scenes often depicted through a window with us as the voyeurs lend themselves well to this sort of treatment. With a few adjustments, it would make a damn cool Tumblr.

Morning Sun and New York Movie are probably my favorites. The slow brightening of the scene in the former brings the title into the action, and the moving picture actually moving is nicely handled in the latter. The flicker in the theater is a bit overdone, in my opinion, with too strong a contrast of light and dark. It doesn’t match what’s being shown on the screen.

I was most looking forward to Nighthawks, but alas, it’s my least favorite of the animations. The blinking light is on too short of a loop and it doesn’t really match the scene because it’s the interior lighting of the diner that flickers instead of a neon sign like Chop Suey. Neon signs flicker all the time. The blinking neon light has become an iconic representation of night life — a little rundown, a little busted, but still vital in its color and brightness. If all the lights in a diner kept turning off and on, you’d just call the power company, and you certainly wouldn’t settle in for the night to enjoy the splendid urban isolation because it would be freaking torture.

The descriptive blurbs on the side are well done. My one criticism there is that they should link to the original paintings instead of just telling you which museums they’re in now.

 

National Museums Scotland gets Galloway Hoard for £1.98 million

Selections from the Galloway Hoard. Photo courtesy National Museums Scotland.The Queen’s and Lord Treasurer’s Remembrancer (QLTR) has allocated the Galloway Viking Hoard to the National Museums Scotland (NMS) on the condition that they make an ex gratia payment of £1.98 million ($2,550,000) to the finder Derek McLennan who discovered the hoard in 2014. NMS has until November of this year to raise the sum. They’ve set up a donation site (which is showing me a DNS error at the moment, probably because it’s brand new).

However, it also contains an outstanding range of exceptional precious metal and jewelled items including a rare gold ingot, a gold bird-shaped pin and a decorated silver-gilt cup of Continental or Byzantine origin. The cup is carefully wrapped in textiles and is the only complete lidded vessel of its type ever discovered in Britain or Ireland.

Other finds from around Britain or Ireland have been exceptional for a single type of object—for example, silver brooches or armlets. However, the Galloway Hoard is unique in bringing Stamp-decorated bracelets from Ireland.

It also contains objects which have never before been discovered in a hoard of this age. Incredibly, fragile textiles, leather and wooden fragments have also survived, providing an extremely rare opportunity to research and reveal many lost aspects of the Viking Age.

The Dumfries and Galloway Council, which launched a campaign earlier this year to keep the hoard in the county where it was discovered, is less than pleased with the QLTR’s decision.

Cathy Agnew, Campaign chair, said: “This treasure was buried in Galloway for safekeeping 1,000 years ago – it is deeply disappointing that the QLTR believes it should be allocated to the National Museum in Edinburgh where it will potentially be lost amongst so many other wonderful artefacts.

“The support from the public, from academics, politicians of all parties, and so many others – across Scotland and the world – to keep the hoard in Galloway, where it would be cherished, has been magnificent. It is a real shame their voices and their passion have gone unheeded.”

Photo courtesy National Museums Scotland.It’s hard for a county council to win against the resources of a national museum, especially when the local museum that would house the hoard has not actually been built yet. They made a valiant effort, drastically increasing the budget for the new Kirkcudbright Art Gallery and raising a great deal of money and support for the cause of keeping the hoard in Dumfries and Galloway. They knew it was a long shot, however, and all the while hoped to be able to come to an agreement with NMS for joint ownership.

It thinks it is the proper home for a treasure of international significance, because they have the wherewithal and expertise to give it all the care and security such complex, delicate archaeological materials need. The preservation of the extremely rare surviving organic remains in particular requires specialists and facilities that the National Museums can provide. Its location in Edinburgh will also “ensure that the Hoard is seen by the maximum number of people, from Dumfries and Galloway, Scotland, the UK and internationally.”

National Museums believes that it is important there is a display of the Hoard in Dumfries and Galloway, and intends to continue to seek a dialogue with Dumfries and Galloway Council to ensure that a representative portion of the Hoard goes on long-term display in Kirkcudbright Art Gallery.

Had they made a tandem bid that was accepted, the bigger museum would almost certainly have had the greater say in the division and exhibition of assets anyway, so in the end the Kirkcudbright Art Gallery might well end up with much the same sort of display it would have had if they had partnered with NMS.

 

Tomb with 17 mummies found in Minya, Egypt

The tomb was found more than 25 feet under the village of Tuna al-Gabal where a number of necropolises have been unearthed containing the mummified remains of animals. This one contained some animal coffins (baboons) too, but the stand-out finds are eight limestone and clay sarcophaguses holding well-preserved, linen-wrapped mummified human remains as well as stacked human remains without coffins. Archaeologists also found two papyri inscribed with Demotic script.

Photo by REUTERS/Mohamed Abd El Ghany.The underground burial chamber was first spotted last year by Cairo University students using ground-penetrating radar, but they only knew it was a hollow space until the excavation this week discovered it was a cachette, an unmarked burial site where mummies were secreted to keep them safe from grave robbers. (The endeavor was of limited success; the site does appear to have been interfered with in antiquity or more recently.) The remains have yet to be radiocarbon dated. Researchers believe they may date to the Late Period — from around 600 B.C. until the conquest of Alexander in 332 B.C. — or possibly to the Greco-Roman period dating from Alexander’s conquest to around 300 A.D.

Photo by REUTERS/Mohamed Abd El Ghany.With such a dense concentration of significant sites spanning the ages from the Old Kingdom to the modern era, you’d think a tomb with a bunch of mummies would hardly be headline news, but this one is unique. For one thing, it’s been a long time since any mummies were found in the area. Not since the discovery of the animal and bird necropolises between 1931 and 1954 have any kind of remains been discovered in Minya. Even more significantly, it’s the first human necropolis discovered in central Egypt to contain such a large number of mummies.

Last but certainly not least:

Archeologists believe that it is the first time to unearth a burial tomb with that number of mummies for ordinary people and in catacombs style. Inside the catacomb, Khaled Anani, Egypt’s Minister of Antiquities referred to the gaps inside the catacombs saying “The more we drill the more we find.”

In one chamber inside the tunnels, human bones and skulls are piled. Most of the mummies were laid in lines in both of its sides. While some them were left in plain stone and wooden sarcophagi, others were piled on top of each other.

Since Minya was known as a center for the worship of the god Toth, they could have been priests associated with his temple.

The excavation has only just begun, and archaeologists expect to find more of the catacomb and more human remains as they proceed. The papyri are being moved to the Grand Egyptian Museum for conservation.

 

Unknown Caxton leaf found in university archive

The newly discovered Caxton leaf. Photo courtesy the University of Reading.A two-sided page from a 15th century priest handbook printed by William Caxton has been discovered in archives of the University of Reading. Written in Medieval Latin, the leaf was part of a book called the Sarum Ordinal or Sarum Pye, a manual for priests on managing feast days for English saints during the ecclesiastical year. It was printed by William Caxton in his shop, the Red Pale, in late 1476 or early 1477 and was one of the first books printed in England. The University of Oxford’s Bodleian Library has a notice from Caxton’s shop promoting the manual which is the earliest surviving printed advertisement in English publishing history.

One of only two known surviving fragments from this enormously significant edition in the history of English publishing, the leaf is in very good condition even though it hasn’t exactly been treated with kid gloves over the years. For three centuries it was glued into the spine of another book to reinforce the binding. It was saved from that ignominy by a University of Cambridge librarian in 1820 who put it in a scrapbook along with other fragments rescued from bindings, but not even he recognized it as an original Caxton page.

“I suspected it was special as soon as I saw it. The trademark blackletter typeface, layout and red paragraph marks indicate it is very early western European printing. It is incredibly rare to find an unknown Caxton leaf, and astonishing that it has been under our noses for so long.”

The pages are part of the John and Griselda Lewis Collection. John Lewis was a typographer and pioneering scholar in the field of printed ephemera. Griselda was a writer. Between them, they amassed a collection of more than 20,000 items pertaining to the history of printing. The University bought the John Lewis Printing Collection at auction in 1997 for £70,000 ($90,000), with the aid of a £60,000 grant from the Heritage Lottery Fund. The collection is stored in 87 boxes at the University of Reading’s Centre for Ephemera Studies in the Department of Typography & Graphic Communication.

The collection is still in the process of being catalogued, which is what Erika Delbecque was doing when she came across the Caxton leaf.

Copies of the Sarum Ordinal were produced in Westminster, before the Reformation, and consisted of around 160 leaves. The text was originally established as a manuscript by St Osmund, the Bishop of Salisbury, in the 11th century. It would have been owned by clergymen and consulted on a regular basis, but was discarded after the Reformation.

Only one other surviving fragment of the book exists, consisting of eight double-sided leaves, which are held at the British Library in London.
