Horning In on Triceratops
In a study published in the journal PLoS ONE, researchers conjecture that the three horns of Triceratops were often used for fighting–because museum specimens show much more scarring than in the horns of a related species. Cynthia Graber reports

Triceratops, as the name suggests, were huge dinosaurs adorned with three horns on their heads. Scientists now say those horns may have been a sort of battle bludgeon. Andrew Farke is a curator at the Raymond M. Alf Museum of Paleontology in California. He became curious about that headgear. Farke and colleagues wanted to investigate whether Triceratops fought each other with their horns. Which posed a problem: obviously, we can’t go back in time to watch the animals interact. So the researchers resorted to some techniques out of a Cretaceous CSI.

They examined more than 400 museums specimens of Triceratops and another closely related one-horned dinosaur called Centrosaurus. They scanned the skulls for injuries around where Triceratops might have locked horns and wrestled. Their assumption was that if the horns were just for display, both species would show few scars.

But the Triceratops had 10 times more skull injuries than their Centrosaurus cousins. The most likely explanation is that they probably jabbed each other in the head while fighting. The researchers published their findings in the journal Public Library of Science ONE. They also caution that the horns could have served more than one purpose—perhaps fighting and flaunting.

    Triceratops horridus skull on bid

    Triceratops horridus skull on bid

    This extremely rare find was discovered on a private ranch in Montana and has been tucked away in the rancher’s house for the past decade. It was kept in field jackets (the original matrix and wrapped in plaster) so the quality and completeness was unknown until the preparation began in July of 2008. One could imagine the pleasant surprise of the new owners when they discovered how complete this skull actually is, over 93% complete! The preservation and bone quality is superb and surprisingly very little distortion has occurred while buried for the past 68 million years. Rarely are dinosaur skulls of this large size found articulated and in one piece, so because of this, extra care and attention was given during the preparation as to not lose any of the scientific data.

    This huge skull measures an impressive 7 ½ feet in length from the beak to the frill making this important specimen one of the largest of its kind and certainly among the most complete. Though the left brow horn was missing it is believe that it was sheared off in battle as the bone indicates it was broken off while the animal was still alive evidenced by signs of healing. Most of the restoration on this skull was on the missing horn along with small areas of the frill, eye orbits and nasal. The lower jaws were found intact and are virtually complete along with most of their original teeth, though most of the teeth in the upper jaws were missing. The frill stretches out over 5 feet wide and is naturally fused to the skull which is common on adult Triceratops. On younger animals the frill would have been separate (in three sections) and held in place by cartilage.

    Another scientifically significant feature of this important skull is the presence of a complete and well preserved brain case which gives us a glimpse of how small their brains were in comparison to their huge and massive bodies.

    Triceratops (meaning three-horned face) was a rhinoceros-like dinosaur that had a short, pointed tail, a bulky body, and walked on short, sturdy, column-like legs with hoof-like claws. They grew in lengths up to 30 feet, up to 10 feet tall, and weighed up to 12 tons, making it the largest dinosaur in the ceratopsians family. They are also among the most recognizable of all dinosaurs and are often portrayed in fearsome battle scenes with the feared Tyrannosaurus rex!

    The skull, together with the lower jaws, has been professionally mounted on an adjustable custom steel armature with three height levels. Wheel casters are included in this display for easy movement. Comes complete with a photo history and documentation from the landowner.

    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.”

    2008-10-13 – Canada: Mostra sui Triceratopi (C.Montreuil profile, Meet the Triceratops)

    Boning up on dinosaurs

    Chantal Montreuil’s dream was to work with animals – live ones, that is. But as a fossil technician at McGill University, it’s her job to piece together the featured exhibit at this week’s Meet the Triceratops event

    BRONWYN CHESTER, Freelance

    Published: 3 hours ago

    It’s the week before the big event and Chantal Montreuil is trying to figure out how to attach the lower jaw of this young triceratops to the upper jaw.

    “What’s difficult is to do it without the wires showing,” said Montreuil, standing back from the two-metre-long dinosaur skull she’s been working on for the past three months at the Redpath Museum.

    Montreuil is learning as she goes – as she has done for the past four years as the fossil technician of McGill University’s evolutionary biology laboratory.

    She is working from hundreds of small fossilized bones that add up to about 70 per cent of a teenage triceratops’s skull – bones collected on digs led by Hans Larsson, a McGill professor of evolutionary biology, in southwestern Saskatchewan.

    On a table in the lab sit the two horns, each weighing close to 10 kilograms, along with a bit of the frill, the upright collar surrounding the head that is characteristic of this Jurassic dinosaur, which wandered in herds until its demise 65 million years ago.

    “There are 200 pieces of frill alone,” Montreuil said. “From the size of the horns and the size of the frill, we knew this was a juvenile.”

    She has been piecing the bones together, gradually, since going on the first dig in Saskatchewan three years ago. But more recently, she has been using the bones as reference points as she adapts a life-size skull made of fibreglass.

    The fibreglass skull and the bones will be on display Friday at the Meet the Triceratops event at Redpath. It’s a chance for the public to learn about McGill’s dinosaur-digging activities.

    Later, Montreuil will embed the bones into the fibreglass model.

    She picked up the original fibreglass model last summer from Research Casting International, a company in Trenton, Ont., that specializes in dinosaur casts. Montreuil has made various cuts to reduce the length of the head and to widen the face to most closely represent the fossil record the McGill team has collected.

    This being her first time working with the material, Montreuil has experimented with different putties, glues, plaster, wire, paint and reinforcing foam. Initially, the fumes emanating from resins in the fibreglass forced her to take the skull out of the museum and put it in her backyard until the odours evaporated.

    “My neighbours got a kick out of that,” said Montreuil, who lives in Plateau Mont Royal.

    Montreuil, too, gets a kick out of her work. Having dropped out of school at 15, had a baby at 18, and worked at menial jobs through the years while completing high school and, finally, Vanier College’s program in ecology technology, the 37-year-old has nothing but appreciation for her job.

    “I’m happy to be doing work I love,” she said.

    Her intention was always to work with animals – but with live ones. Raised by parents who collected edible plants and hunted every fall, Montreuil grew up in Verdun knowing her plants and animals. Later, in her mid-20s and living in Vancouver, she learned to scuba dive and became a volunteer in the city aquarium’s marine mammal rehabilitation program, where she taught orphaned seals to hunt and return to the sea.

    As fate would have it, however, the first job Montreuil landed after Vanier was a contract to put together a display for the Redpath Museum’s exhibit on biodiversity. Her qualifications for that job had as much to do with her manual skills as with her knowledge of nature. With a carpenter father and a mother who ran a crafts store, Montreuil knew how to use her hands. To this day, she keeps a studio in Mile End where she makes lampshades and sculpts imaginary creatures in papier mâché.

    Montreuil was also happy to have work in her field that didn’t require uprooting herself and her son. “I thought to myself, ‘I’m a wildlife technician living in the middle of the city. Not bad,’ ” she said with dry humour.

    At the end of that contract, Larsson was looking for a technician. And the rest, as they say, is prehistory. With knowledge of paleontology gleaned during her son’s dinosaur-loving period and from the Vanier program, Montreuil took on the job, learning from Larsson and through trial and error.

    “My aptitude for jigsaw puzzles and for packing came in handy,” she joked.

    Participating with Larsson and a dozen students in the annual May dig in Saskatchewan, however, has proven to be the most useful experience in the preparation of fossils.

    “Seeing these fossils in the ground and visualizing the scene around an ancient riverbed, it gives me a better feel for my work,” Montreuil said. “I’m a bit like the detective who needs to go to the scene of the crime.

    “The dig is also an opportunity for me to learn from the paleontology technicians at the Royal Saskatchewan Museum and Alberta’s Royal Tyrrell Museum.”

    Quebec has its own paleontology technicians, but their specialization is fossilized fish. Miguasha, in the Gaspé, is a World Heritage Site for Devonian (Age of Fishes) fossils from 370 million years ago. The Age of Reptiles – dinosaurs being the most highly evolved reptile – was a mere 245 million to 65 million years ago.

    The triceratops skull will give Montrealers just their second dinosaur: It will take its place beside the albertosaurus that has ruled alone on the museum’s second floor for the past 16 years.

    “It’s all very poetic, because it is thanks to the albertosaurus that I learned of this museum,” Montreuil said. “When my son was little, he showed me one of those Jurassic Park (movie) books about the tyrannosaurus. There was a photo in there of the Albertasaurus and in the credits was the name of the Redpath Museum, Montreal. That led to my first visit.”

    Meet the Triceratops is a McGill University Homecoming event that features a presentation by evolutionary biology professor Hans Larsson. Proceeds will be used to acquire and display a complete triceratops family – parent, teenager and baby. Suggested contributions are $12 per adult, $5 per child, and $20 per family. No reservation is necessary. The event takes place Friday from 4 p.m. to 6 p.m., at the Redpath Museum, 859 Sherbrooke St. W. Call 514-398-4086.

    2008-09-25 – “Leonardo” (Brachylophosaurus canadensis) fornisce nuove informazioni sulla dieta egli Adrosauri

    Well-Preserved Dinosaur Guts Give Insight Into Prehistoric Diet

    Thursday, September 25, 2008

    An analysis of the gut contents from an exceptionally well-preserved juvenile dinosaur fossil suggests that the hadrosaur’s last meal included plenty of well-chewed leaves digested into tiny bits.

    The fossil, Brachylophosaurus canadensis aka “Leonardo,” is the second well-substantiated case in which the gut contents of a plant-eating dinosaur have been revealed, said Justin S. Tweet, who was a graduate student at the University of Colorado at Boulder when he studied the fossil with colleagues there including paleontologist Karen Chin.

    The dino, found in what geologists call the Judith River Formation, in Montana, will go on display to the public Friday at the Houston Museum of Natural Science’s “Dinosaur Mummy CSA: Cretaceous Science Investigation” exhibition.

    “Our interpretation suggests that the subadult Judith River Formation brachylophosaur had a leaf-dominated diet shortly before its death,” the authors write in the September issue of PALAIOS, the journal of the Society for Sedimentary Geology.

    Skin and scales

    Leonardo is a 77-million-year-old duckbilled dinosaur whose remains are covered with patterned fossilized skin. The specimen has given scientists a rare peek inside a dinosaur. Digital technology and X-ray scans, some of which were conducted at NASA Johnson Space Center’s Ellington Field facility in Texas, has helped paleontologists reconstruct what Leonardo looked like in life, what it ate, its muscle mass and its limb movements.

    An analysis of pollen found in the specimen’s gut region revealed a variety of plants, including ferns, conifers and flowering plants. Although the pollen could have been ingested when the dinosaur drank water, the tiny leaf bits, under 5 millimeters (a quarter-inch) in length, indicate that Leonardo was a big browser of plants, Chin said.

    Hadrosaurs were certainly capable of processing food into tiny bits in part with their continually replacing teeth and grinding jaws.

    The tricky part with the analysis was building a case that the plant matter found inside the gut came from the dinosaur’s last meal, not from material that penetrated the body or flowed into the area after death. The case was helped by the fact that Leonardo was buried quickly and undisturbed by scavengers, and its body cavity appears to be undisturbed. At least 12 percent of the gut contents in the carcass included organic matter, such as leaves. The rest was clay and grit. Some of the inorganic stuff probably flowed into the body after death, Tweet said.

    Overall, the most exciting part of the research was working with material that could actually be gut contents, Tweet said.

    “This is very rare for dinosaurs, where we usually have to settle for generalizations of feeding behavior based on skull anatomy,” he told LiveScience.

    The research was funded by grants through the University of Colorado and its Museum of Natural History and a Geological Society of American Graduate Student Grant.

    ‘Cranial Cuisinart’

    Houston Museum of Natural Science Curator of Paleontology Robert T. Bakker, one of the first scientists to work on the fossil, said that duckbill dinosaurs like Leonardo had large bills and jaws full of tiny teeth, about 800 of them, that ground and chopped tough plants and plant parts, including conifer needles, bark and twigs, like a “cranial Cuisinart.”

    The contents of the gastrointestinal tract then were processed by digestive juices and gut microbes.

    Leonardo has a pebbly skin texture, like the lower leg of an ostrich or another big bird, Bakker said, but on the front of Leonardo’s ankle and shin, the skin becomes very thick like armor which helped it move through the underbrush.

    The fossil was discovered in the summer of 2000 during an expedition to a cattle ranch about 15 miles north of Malta, Mont. Leonardo was named after graffiti found on a nearby rock that read: “Leonard Webb loves Geneva Jordan 1916.”

    The Houston exhibition will also feature an icthyosaur “mummy,” which has contents of her intestines and four babies preserved inside her body, and the only mummified Triceratops skin ever found. The exhibition’s opening was delayed a week as a result of conditions and power losses in the Houston area after Hurricane Ike, including five days without primary power at the museum. Leonardo and other exhibition specimens were unharmed, a museum spokeswoman said.

    Probable Gut Contents Within A Specimen Of Brachylophosaurus Canadensis (Dinosauria: Hadrosauridae) From the Upper Cretaceous Judith River Formation Of Montana

    Justin S. Tweet, Karen Chin, Dennis R. Braman, and Nate L. Murphy
    PALAIOS 2008 23: 624-635. [Abstract] [Full Text] [Figures Only] [PDF]  

    Abstract – An exceptionally preserved subadult specimen (JRF 115H) of a hadrosaurid, Brachylophosaurus canadensis, from the Judith River Formation near Malta, Montana, contains abundant plant fragments concentrated within the body cavity. We examined the taphonomy of the carcass and analyzed the gut-region material to test whether the organic remains represent fossilized gut contents. The dinosaur was buried in a fluvial channel setting, and the excellent articulation, integument impressions, and lack of scavenging indicate rapid burial. The organic material occupies a volume of at least 5750 cm3, and comparable material is not found outside the carcass. The carcass contents include about 63% clay, about 16% undetermined matrix, about 12% organic matter, and about 9% larger inorganic clasts—mostly 50–100 µm quartz grains. Most of the organics appear to be mm-scale leaf fragments. The most parsimonious explanation for the presence and composition of the gut-region material is that much of the plant fossils represent reworked brachylophosaur ingesta influenced by flowing water that entered through openings in the carcass and introduced clay. The evidence strongly suggests that the hadrosaurid ate significant quantities of leaves and processed them into small pieces. This study provides baseline information for analyzing other cases of putative gut contents in herbivorous 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). For more information, the public can call 617/723-2500, (TTY) 617/589-0417, or visit www.mos.org.
