“A vast cloud of searing vapor and debris raced over the continent,” Kolbert writes, “expanding as it moved and incinerating anything in its path. This week at auction: Megalodon - Tooth - Carcharocles megalodon - 131×92×22 mm. “The commercial collectors are specifically looking for the rare specimens because they bring in the big bucks. Second, and even worse, the pieces collectors like Cage want are the rarest of the rare—the very objects that scientists like Shimada have the most difficulty accessing, regardless of resources, for their research. Fossil Dealers and Collectors has 2,796 members. Whatever the actual measure of its destructive force, the 150-mile-wide crater left in its wake is evidence of some sort of impact, while the dust and debris that was immediately hurled into the atmosphere is thought to have triggered the extinction of roughly 75 percent of all plants and animals on the planet. Simply put, specimen collectors may find themselves in situations where they could engage in illegal conduct seemingly without fear of discovery or negative repercussions. Currently, one such dog-like creature has caught Boyce’s eye. of Words: 257 250 Senator, prior to the approval of a BLM budget, that it probably cost the U.S. taxpayer almost $175,000 a year to pay for a BLM armed “fossil cop.” I roughly computed this at the then annual salary, benefits, 4-wheel drive truck, communications gear, guns, handcuffs and bullets (to shoot fossil thieves?). No. al. And private fossil hunters maintain that … Indeed, museums are where most of us got our first up-close look at a dinosaur skeleton, so that’s where this idealized stereotype comes from. I once pointed out that a simple geologic map computation shows that, in the San Juan Basin of the Four Corners, for example, there is more Upper Cretaceous exposed than the total land area of the state of Indiana. The bane of the fossil business is the lab work, sitting in a dusty lab for hours and hours, and at the end of those hours you don’t have much to show for what you’ve done.”. According to a version of the extinction event published in Elizabeth Kolbert’s eye-opening new book, “The Sixth Extinction,” Chicxulub hit Earth from the southeast, which means North American theropods were among the first to be wiped out. A fossil … So the idea that fossils found on public lands should belong to the public became a reality.”. There’s a mass-mortality site at a privately owned quarry near Faith, South Dakota, about 100 miles north of Rapid City. There are more fossils than museums can use but it is a problem because private collector will buy what museums don’t want? Meanwhile, a different set of challenges face paleontologists studying dinosaur fossils in the United States. Shimada and his ilk make me want to bang my head. I suspect that $175,000 has grown t perhaps $250,000 now. Photo via I. M. Chait. From Business: OakRocks.net has everything lapidary related for the rock, mineral, and fossil collectors. “There are fossil woods in western Wyoming from the Eocene,” Boyce says of the epoch that preceded his beloved Oligocene, between which there was yet another extinction event. But this one became noteworthy when a former director of the auction company that sold Cage his prized dino skull recently revealed that the artifact had been supplied by a commercial paleontologist named Eric Prokopi, who pleaded guilty in late 2012 to smuggling a full T. bataar skeleton (among other fossils) out of Mongolia. We need more collectors, not fewer. Photo via Heritage Auctions. That’s not good enough for Shimada and Kelley, who believe that we’ve reached a point where the incentive to bend the rules, or discard them altogether, has become stronger than the glory gained by reporting a major fossil site and then maybe having your name attached to it (probably, alas, as a footnote in some scientific journal that few will read). Photo by Kevin and Jennifer of Two Years Off. “The majority of my time is spent in the White River Badlands, which contain layers from the Oligocene Epoch,” he says of the South Dakota formations that regularly cough up fossils 23-to-34 million years old. Fossilized ammonites from southern Alberta, Canada, are prized for their iridescence. The real tragedy in all of this is that guys like Shimada are so out of touch with the realities, in that interest in paleontology goes up (along with public funding) when young people can dig up or buy their own fossils and build up a personal collection. Making anything less available, is what drives up the price… you know supply and demand. The attorney was escorted from the room. The shady provenance of that fossilized skeleton, which was sold at Heritage Auctions in May 2012, had been flagged by a number of paleontologists, including Neil Kelley, who posted a petition at Change.org to call attention to the sale (he has since earned a Ph.D. from University of California, Davis, and is now doing his postdoctoral research at the Smithsonian, studying the evolution of land mammals that evolved to live in the ocean and became things like whales, dolphins, and manatees). Rock And Mineral Shops Phoenix in Phoenix on YP.com. This makes scientists like Shimada extremely nervous for a number of reasons. “The reason why there are so few museums that can take the specimens,” he says, “is because the job market for paleontologists is shrinking, as is the funding to collect and house fossils in museums. She also gives numulites in return for identified or unidentified fossils found around the island: Small fossils can be exchanged for 100 numulites. Those are pretty interesting patterns, and we can follow them in the fossil record. In contrast, the lecture posits that it is better to find more fossils rather than leaving fossils undiscovered, which is possible due to private collectors. An early example of that is a dinosaur discovered in England called the Iguanodon. “I use everything from dental picks to camelhair brushes to miniature sand blasters like the ones used in the Silicon Valley to clean computer chips. Most of the time (certainly at least 10 months of the year) no paleontologists are out in the San Juan collecting fossils. of Grammatical Errors: 0 2 The enamel on the teeth is very thin, and because there are two different materials in the living animal—the core of the tooth and the enamel—the same is true of the minerals that replace those materials and create the fossil. “On all teeth, dinosaur and mammal alike, cementum makes up the core of the tooth, which is covered by an outer layer of enamel. Photo via Wikipedia. of Sentences: 13 12 And yet I have seen paleontologists walk unconcernedly over wonderful animals in the field because that particular fossil wasn’t going to fit their theory or advance their career. “It was the first really bountiful time for mammals,” he says. al. Nobody knows anything about them. Above: Erosion reveals more fossils every year, which makes places like the White River Badlands in South Dakota prime spots for paleontologists. ED-00002211 $40.38 Or do we know for an absolute fact that those fossils would last about 2 years at the surface before becoming so damaged they would be useless to science anyway. “There are so many differences with it,” he adds, which makes it an obvious example of something to show to a scientific colleague rather than just another piece to clean up and put on the market. My personal view is that we should not commercialize fossils whatsoever, but I know on a practical level that’s just not possible.”, “There aren’t 300 museums in the world that want a Triceratops.”, As one of those commercial paleontologists, Japheth Boyce would certainly never condone removing a theropod trace fossil, or anything else, from public lands, but he argues that the situation is not quite as dire as Shimada paints it. Mass extinction events were convenient places to draw boundaries.”. But we don’t want to put ourselves in a position where we’re purely at the whim of those who have the resources to buy scientifically important and unique fossils, and then they can decide what they want to do with them.”, “The problem is the uncertainty of the permanency,” agrees Shimada. This fossilized megalodon shark’s tooth, which is more than 5 inches long and anywhere from 2-to-12 million years old, is being offered by eBay seller piecesfromthepast-1.
