2008-11-23 – Portogallo: polemiche per la vendita all’asta di un dinosauro (Portugal, Dinosaur tail sale)

Un macchinista di escavatore ha scoperto casualmente resti di un Sauropode e si è rifiutato di cederli ad un museo nazionale, anzi le ha messe all’asta su internet ….


Dinosaur tail sale sparks anger in Portugal

A Portuguese bulldozer driver who is selling a dinosaur fossil he found online has been criticised by experts for refusing to hand the bones over to a museum.

Last Updated: 12:08AM GMT 22 Nov 2008

Gonsalo Ribeiro, who has refused to reveal where exactly in western Portugal he discovered the bones, decided to cash in on his lucky find by offering it up for sale on the internet.

“For sale, dinosaur spine 90 per cent intact,” reads his advertisement, posted in the antiquities section of a website.

“I own an excavation business, and one day when we were out digging, we came across some stones. But when I took a closer look, I noticed they were not stones,” said Mr Ribeiro.

He says that what he thought were stones are a 11.8-foot- long sauropod’s tail.

The archaeological find is between 146 and 152 million years old and of “huge scientific value”, according to palaeontologist Octavio Mateus.

But Mr Ribeiro has refused to hand over his treasure to a museum, claiming “the figures they offer are far off the mark.” He has already turned down an offer of 100,000 euros (£84,000).

Mr Mateus, who works at a museum specialising in the Jurassic period in central-west Portugal, published a note on the website denouncing what he called the “sale of our heritage as if it were a car or a pair of shoes”.

Mr Mateus is calling for his government to introduce a law, like those of Argentina, China and Mongolia, making it illegal to sell on “public heritage”.

With nudge, a trail of prehistory winds here

By Irene Sege

Globe Staff / November 13, 2008

The brain of Triceratops Cliff, the newest resident of Boston’s Museum of Science, may have been the size of a potato, but its 800-pound head took five people three hours to install. Come Saturday, Cliff will star in an exhibit that could well become the museum’s most famous. It is apparently one of only four nearly complete triceratops skeletons on public display in the world.


How Cliff came to be loaned to the museum for seven years is a remarkable tale that started in 2004 in the rugged, fossil-rich Hell Creek Formation in the Badlands of North Dakota and wound its way to Christie’s auction house in Paris, where a Boston-area art collector bought it for $942,797 in April and named it Cliff, after his grandfather. It was the second dinosaur skeleton ever auctioned, the first being Tyrannosaurus Sue, which Chicago’s Field Museum purchased for $8.4 million from Sotheby’s in 1997. The last stage of Cliff’s journey began in late April, when the buyer, who wants to remain anonymous, called the science museum.

“The museum gets lots of calls along these lines: ‘I have this fill-in-the-blank.’ This is the first time that anybody’s said, ‘I have this dinosaur,’ ” said Paul Fontaine, the museum’s vice president of education. “I was speechless.” The Museum of Science has revealed little about the donor except to note that he enjoyed visiting the museum as a child.

At an invitation-only preview yesterday, fifth-graders from the Excel Academy Charter School in East Boston sat rapt as museum officials pulled the curtain on the dramatic 9-foot-tall, 22-foot-long, 2,000-pound skeleton that appears to be charging into a mural-sized photograph of Hell Creek.

The stark, semi-arid landscape of southwestern North Dakota where Cliff was found bears little resemblance to the subtropical delta of the Cretaceous era, rich in plants and animals, where triceratops and tyrannosaurus rex and a dozen other dinosaur species roamed more than 65 million years ago. Its sedimentary rocks, formed by layers of sand and silt hardened by pressure and time, provide fertile ground for prehistoric fossils. Usually the fossilized bones are trapped under a mountain, or they have been scattered by the elements or the scavengers that picked over the carcass.

What an unnamed fossil prospector unearthed in 2004 was stunning.

“A 70 percent complete animal is very rare,” said John Hoganson, North Dakota’s state paleontologist. “It’s highly significant from a scientific viewpoint because they provide a lot of information not only about the animal but about how the animal might have lived.”

The three-horned triceratops, one of the last dinosaurs to go extinct and the largest plant-eating animal of its era, used its sharp teeth to grind vegetation, and, at 12,000 pounds, it spent most of its day eating. Like sharks, it shed teeth, and rows of teeth waiting below the gumline are visible in Cliff’s giant jaw. It used its horns to charge competitors and predators, the most dangerous of which was T. rex, the largest carnivore of the day, whose bite marks have been found on some triceratops fossils. The fan-like frill surrounding its massive head provided added protection.

An unnamed German collector of contemporary art and fossils bought the bones for an undisclosed sum and then shipped the rocks, wrapped in burlap dipped in plaster of Paris, to Europe. Cliff remained in pieces until December 2007, when an Italian firm cast models of the missing bones and assembled the skeleton for display in Christie’s rotunda in March. “It was an amazing rush job,” said Lynn Baum, an exhibit planner at the science museum.

The art collector who purchased Cliff was browsing European old masters paintings at Christie’s when he spotted the dinosaur. “He was struck by the beauty of the specimen,” Fontaine said. The sale came one year after Christie’s France, in its first auction of paleontologic items, sold a Siberian mammoth for $352,000.

In North Dakota, Hoganson didn’t learn of Cliff’s existence until a week before the auction, because it had been discovered on private land. Scientists can gather important geological information about the animal’s habitat from the area where a fossil was unearthed. “That information is lost for Cliff,” Hoganson said. “It’s kind of like having an archeological pot that is taken out of context from where the pot was made.”

Cliff arrived at the museum in September, shipped by freighter in 10 crates. In October, after moving a mineral exhibit to make room for Cliff, museum staff using giant lifts began assembly. The bones were numbered, but Christie’s had forwarded no manual. “It wasn’t obvious how the shoulder blades went in,” said senior curator Carolyn Kirdahy. Establishing the curve of the spine that would have Cliff poised in perfect balance proved difficult.

“The spine kept getting higher and higher and closer to the ceiling,” Kirdahy said. “It was, ‘Is it going to fit?’ ”

It did fit. Now Cliff becomes the third nearly complete Triceratops skeleton on display in the United States, joining Kelsey at the Children’s Museum of Indianapolis and an unnamed composite of two animals found near each other at the Science Museum of Minnesota in St. Paul. A fourth, Raymond, is in Japan. The skeletons at the American Museum of Natural History in New York and the Smithsonian Museum of Natural History in Washington are each composites of several animals.

“To have one of this size is really extraordinary,” Baum said. “It’s a wonderful teachable moment, because people come in already excited about dinosaurs.”

Triceratops vinto all’asta in mostra la Museo di Boston, USA

World’s First Triceratops Sold at Auction Will Be Unveiled in Boston

Museum of Science, Boston to open new exhibit, Colossal Fossil: Triceratops Cliff November 15, 2008 Anonymous donor provides extremely rare and mostly complete, 65-million-year-old dinosaur fossil to Museum on long-term loan

Last update: 10:40 a.m. EDT Sept. 22, 2008
BOSTON, Sep 22, 2008 (BUSINESS WIRE) — The Museum of Science, Boston today announced that it will unveil an extremely rare dinosaur fossil for the first time to the public this fall — a skeleton of Triceratops horridus that was auctioned at Christie’s in Paris earlier this spring. According to Christie’s, the fossilized Triceratops skeleton is mostly complete, making it one of the world’s rarest paleontological finds. There are currently only three other largely complete Triceratops fossils on public display in the world. To present the fossil, the Museum has developed a new exhibit, Colossal Fossil: Triceratops Cliff, which will open November 15, 2008. Named after the donor’s grandfather, Triceratops Cliff is the fossilized remains of a real Triceratops who lived and died over 65 million years ago. The exhibit will allow visitors to imagine Cliff’s life and death in the age of the dinosaurs, as they examine evidence found in this extraordinary fossil, including large scars on its massive, three-horned skull.
The fossil made international headlines in April 2008 when it became the world’s first Triceratops to go on public auction. The only other dinosaur ever to be auctioned is Sue, a Tyrannosaurus rex that sold in 1998. The highly coveted Triceratops fossil was purchased for $942,797 by an anonymous American collector. Wishing to have the fossil displayed for the education and enjoyment of the public, the collector generously offered the fossil on long-term loan to the Museum of Science.
“The Museum is honored to be the new home for Triceratops Cliff, where it will be available to students, researchers, and the general public for the first time,” said Paul Fontaine, Museum vice president of education. “We are grateful to the donor, who was committed to sharing this amazing discovery with as many people as possible. The Museum looks forward to opening the new exhibit in November, which we hope will inspire future paleontologists and dinosaur enthusiasts of all ages.”
Triceratops Cliff was discovered in the Hell Creek Formation of the Dakotas in 2004. This is an area comprised of sedimentary rocks that formed during the Cretaceous period, which ended about 65 million years ago. The “colossal fossil” measures approximately 25 feet long and weighs about two tons. The specimen bears two large gashes in the frill surrounding its head, suggesting a possible battle with a Tyrannosaurus rex or another triceratops.
In Colossal Fossil, visitors will learn about the Hell Creek Formation and discover why the area is so rich with fossils. Visitors will explore other fossils from the Cretaceous period, such as fish and turtles, learning about flora and fauna that existed in Cliff’s lifetime. Virtual exhibit interactives will allow visitors to zoom in for a closer look at Cliff–right down to the bone, and compare a model to the real fossil.
Colossal Fossil: Triceratops Cliff will open Saturday, November 15, 2008. The exhibit is ongoing and included with regular Exhibit Halls admission: $19 for adults, $17 for seniors (60+), and $16 for children (3-11).

Rare fossil found near Browning may be auction’s top draw

This nearly complete duckbill dinosaur, found in the spring of 1990 in the Two Medicine Formation, will be sold at a private auction this weekend in Dallas.

Raising concerns about the loss of scientifically significant fossils, a rare juvenile duckbill dinosaur found in the Two Medicine Formation near Browning is the top item at a private auction in Dallas on Sunday.

The second annual Natural History Auction of the Heritage Auction Galleries features more than 390 lots including dinosaurs, the only meteorite known to have killed a living being, a wolf skull dating back to the Ice Age and a piece of the moon.

The item getting the most attention and most likely to bring the highest price and is a nearly complete juvenile duckbill skeleton found in the spring of 1990 on the Agee Ranch. The skeleton has no current online bids, but the auction house hopes it will sell for $240,000 to $300,000.

“That particular specimen is at least a gray-market, if not a black-market specimen,” said David Trexler, a paleontologist with the Two Medicine Dinosaur Center in Bynum. “It could have been a museum exhibit if it had been collected appropriately. The sad thing is that it’s basically a $150,000 lawn ornament.”

Heritage Auction Galleries spokesman Bruce Bobbins said the person who previously owned the skeleton and its discoverer want to remain anonymous.

What the auction house can say about the dinosaur is that it was found in the spring of 1990.

The juvenile was laying on its side near another juvenile Edmontosaurus and a partially complete adult, according to the auction house. Bobbins said auction officials theorize the dinosaur family was crossing a river that suddenly swelled.

Looking at the photo of the duckbill, Trexler suspects it’s a Maiasaura, similar to what was found on Egg Mountain. Maiasaura are the only duckbills with crests on their foreheads, and the level of the formation on the Agee Ranch is from the era when Maiasaura, not Edmontosaurus, roamed Montana, he said.

Trexler said the dinosaur could have been scientifically significant. While many duckbill babies, adults and teenagers have been discovered — several by his family on Egg Mountain — few have been found that are the age and size of the juvenile up for auction.

The 10-foot-long, 5 1/2-foot-wide skeleton was 90 percent complete — another rarity in the paleontology world.

However, because it wasn’t properly excavated, with documentation of where it was found and the environment surrounding it, science can learn little from the fossil, Trexler said.

The lack of documentation also raises concerns that it might have been obtained illegally, he said.

Trexler said the only juvenile duckbill discovery he was aware of during that time period was allegedly stolen off the Blackfeet Reservation. He heard a report of a juvenile duckbill that was 10-feet-long being discovered, but when he went to the site on tribal land, it was gone.

A federal court decision out of South Dakota dictates the ownership of dinosaurs. Basically, anything found on private land belongs to the landowner and anything found on state or federal land can be claimed by a state museum or no one at all.

For example, the Blackfeet Tribal Business Council recently decided to try to sell a 74-million-year-old baby Tyrannosaurus, hoping to stave off budget shortfalls. That specimen has not yet been sold.

The federal court ruling causes many important finds to become worthless because they are either washed away on public lands because there aren’t enough paleontologists or museum resources to collect them, or they are improperly excavated by commercial diggers.

To properly excavate and mount a fossil costs about $350,000, according to Trexler. Museums can afford to pay the costs because the exhibit can cover the expense. To sell any fossil for the price that private collectors are willing to pay means cutting corners during excavation, he said.

But as evident from the fact that no one has placed the minimum $143,000 bid for the juvenile duckbill on the Heritage Auction Galleries Web site, the commercial market for dinosaurs is small.

“Dinosaurs aren’t worth the millions of dollars that people think they are,” Trexler said. “There’s only so much that people can reasonably afford to pay to have something in their living room.”
