Fossil Trade
The fossil trade is the purchase and sale of fossils. This is many times done illegally with stolen fossils, and many important scientific specimens are lost each year. The trade is lucrative, and many celebrities collect fossils. The fossil trade has attracted criticism from many paleontologists, who regard the private ownership of fossils to be damaging to science. History The auction of the ''Tyrannosaurus'' skeleton known as Sue in 1997 for $8.3 million is considered to have caused an increased interest in the fossil trade. According to the head of science and natural history at Christie's, James Hyslop, the market in fossils has been growing consistently since 2007. Due to the increased awareness of the lucrative nature of fossils, many landowners have become more reluctant to work with scientists, preferring to instead offer prospecting rights to the highest bidder. The international trade in fossils for use in alternative medicine, commonly referred to as "dragon bone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossils
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

US Congress
The United States Congress is the legislature of the federal government of the United States. It is bicameral, composed of a lower body, the House of Representatives, and an upper body, the Senate. It meets in the U.S. Capitol in Washington, D.C. Senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a governor's appointment. Congress has 535 voting members: 100 senators and 435 representatives. The U.S. vice president has a vote in the Senate only when senators are evenly divided. The House of Representatives has six non-voting members. The sitting of a Congress is for a two-year term, at present, beginning every other January. Elections are held every even-numbered year on Election Day. The members of the House of Representatives are elected for the two-year term of a Congress. The Reapportionment Act of 1929 establishes that there be 435 representatives and the Uniform Congressional Redistricting Act requires tha ...

List Of Dinosaur Specimens Sold At Auction
Many dinosaur specimens have been sold at auction, as part of the fossil trade. On average, around five dinosaur skeletons are put up for auction each year. These specimens are mostly purchased by wealthy private collectors and museums in Europe and the United States, though interest has been growing in China as well. The private sale of fossils has attracted criticism from paleontologists, as it presents an obstacle to fossils being publicly accessible to research. Most countries where relatively complete dinosaur specimens are commonly found have laws against the export of fossils. The United States allows the sale of specimens collected on private property. As such, the majority of dinosaur fossils sold at auction were collected in the United States. However, smuggled specimens, particularly from Mongolia, also appear at auctions, often with falsified information on their source. This list includes both specimens sold at auction and specimens that were scheduled to be sold at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiquities Trade
The antiquities trade is the exchange of antiquities and archaeological artifacts from around the world. This trade may be illicit or completely legal. The legal antiquities trade abides by national regulations, allowing for extraction of artifacts for scientific study whilst maintaining archaeological and anthropological context. The illicit antiquities trade involves non-scientific extraction that ignores the archaeological and anthropological context from the artifacts. Legal trade The legal trade in antiquities abide by the laws of the countries in which the artifacts originate. These laws establish how the antiquities may be extracted from the ground and the legal process in which artifacts may leave the country. In many countries excavations and exports were prohibited without official licenses already in the 19th century, as for example in the Ottoman Empire. According to the laws of the countries of origin, there can't be a legal trade with archaeological artifact without o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halszkaraptor
''Halszkaraptor'' (; meaning " Halszka's seizer") is a genus of waterfowl-like dromaeosaurid dinosaurs from Mongolia that lived during the Late Cretaceous period. It contains only one known species, ''Halszkaraptor escuilliei''. The type specimen (holotype) has been compared to the bones of extant crocodilians and aquatic birds, and found evidence of a semiaquatic lifestyle, while some researchers question about semiaquatic ecology. A phylogenetic analysis revealed it was a member of the basal subfamily Halszkaraptorinae, along with ''Mahakala'' and ''Hulsanpes''. History of discovery The holotype specimen of ''Halszkaraptor'' likely came from the Djadochta Formation at Ukhaa Tolgod in southern Mongolia, and was illegally removed by fossil poachers. The fossil found its way to Japan and Great Britain, being owned by several collectors for some years until the Eldonia company of fossil dealer François Escuillié obtained it. He identified it as a new species, and in 2015 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nicolas Cage
Nicolas Kim Coppola (born January 7, 1964), known professionally as Nicolas Cage, is an American actor and film producer. Born into the Coppola family, he is the recipient of various accolades, including an Academy Award, a Screen Actors Guild Award and a Golden Globe Award. In the first few years of his career, he starred in a variety of films such as ''Valley Girl'' (1983), ''Peggy Sue Got Married'' (1986), ''Raising Arizona'' (1987), ''Moonstruck'' (1987) and '' Wild at Heart'' (1990). During this period, John Willis' Screen World, Vol. 36 listed him as one of 12 ''Promising New Actors of 1984''. For his performance in ''Leaving Las Vegas'' (1995), he won the Academy Award for Best Actor. He subsequently appeared in more mainstream films, including '' The Rock'' (1996), ''Con Air'' (1997), ''Face/Off'' (1997), '' City of Angels'' (1998), '' Gone in 60 Seconds'' (2000), ''The Family Man'' (2000), ''Windtalkers'' (2002), the ''National Treasure'' film series (2004–2007) ...

Tarbosaurus Bataar
''Tarbosaurus'' ( ; meaning "alarming lizard") is a genus of tyrannosaurid dinosaur that flourished in Asia about 70 million years ago, at the end of the Late Cretaceous Period, considered to contain a single known species, ''Tarbosaurus bataar''. Fossils have been recovered from the Nemegt Formation of Mongolia, with more fragmentary remains found further afield in the Subashi Formation of China. Although many species have been named, modern paleontologists recognize only one, ''T. bataar'', as valid. Some experts see this species as an Asian representative of the North American genus ''Tyrannosaurus''; this would make the genus ''Tarbosaurus'' redundant. ''Tarbosaurus'' and ''Tyrannosaurus'', if not synonym (taxonomy), synonymous, are considered to be at least closely related genera. ''Alioramus'', also from Mongolia, has previously been thought by some authorities to be the closest relative of ''Tarbosaurus'', though this has since been disproven with the discovery of ''Qian ...

Stan (dinosaur)
"Stan", also known by its inventory number BHI 3033, is a ''Tyrannosaurus rex'' fossil found in the Hell Creek Formation in South Dakota, just outside of Buffalo in 1987, and excavated in 1992. It is the fifth most complete '' T. rex'' fossil discovered to date, at more than 70% bulk. In October 2020, the fossil was sold for $31.8 million at auction, making it the most expensive dinosaur specimen and fossil ever sold. In March 2022 Abu Dhabi's Department of Culture and Tourism stated that they had acquired Stan and were planning on displaying the fossil at a new museum of natural history slated to open in 2025. Discovery Stan Sacrison, an amateur paleontologist, was responsible for the initial discovery of Stan's bone fragments, and as a result is the namesake for the ''T. rex''. He was out looking at plant life in South Dakota when he spotted Stan's pelvis visible in the side of a cliff. At the time, Sacrison was doing freelance work for the Black Hills Geological Institut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeoraptor
"Archaeoraptor" is the informal generic name for a fossil chimera from China in an article published in ''National Geographic'' magazine in 1999. The magazine claimed that the fossil was a " missing link" between birds and terrestrial theropod dinosaurs. Even before this publication, there had been severe doubts about the fossil's authenticity. A further scientific study showed it to be a forgery constructed from rearranged pieces of real fossils from different species. Zhou ''et al.'' found that the head and upper body belong to a specimen of the primitive fossil bird ''Yanornis''.Zhou, Zhonghe, Clarke, Julia A., Zhang, Fucheng. "Archaeoraptor's better half." ''Nature'' Vol. 420. 21 November 2002. pp. 285. A 2002 study found that the tail belongs to a small winged dromaeosaur, ''Microraptor'', named in 2000. The legs and feet belong to an as-yet-unknown-animal.Holden, Constance. "Florida Meeting Shows Perils, Promise of Dealing for Dinos" ''Science'' 14 April 2000. Vol.288 no.5 ...

Microraptor
''Microraptor'' (Greek, μικρός, ''mīkros'': "small"; Latin, ''raptor'': "one who seizes") is a genus of small, four-winged dromaeosaurid dinosaurs. Numerous well-preserved fossil specimens have been recovered from Liaoning, China. They date from the early Cretaceous Jiufotang Formation (Aptian stage), 125 to 120 million years ago. Three species have been named (''M. zhaoianus'', ''M. gui'', and ''M. hanqingi''), though further study has suggested that all of them represent variation in a single species, which is properly called ''M. zhaoianus''. ''Cryptovolans'', initially described as another four-winged dinosaur, is usually considered to be a synonym of ''Microraptor''. Like ''Archaeopteryx'', well-preserved fossils of ''Microraptor'' provide important evidence about the evolutionary relationship between birds and earlier dinosaurs. ''Microraptor'' had long pennaceous feathers that formed aerodynamic surfaces on the arms and tail but also on the legs. This led paleon ...

Yanornis
''Yanornis'' () is an extinct genus of fish-eating Early Cretaceous birds. Two species have been described, both from Liaoning province, People's Republic of China, China: ''Yanornis martini'', based on several fossils found in the 120-million-year-old Jiufotang Formation at Chaoyang, Liaoning, Chaoyang, and ''Yanornis guozhangi'', from the 124-million-year-old Yixian Formation. Description ''Y. martini'' was the size of a chicken,Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2010 Appendix./ref> had a long skull with about 10 teeth in the upper jaw and 20 teeth in the lower jaw, and was both able to fly and walk well, having a well-developed U-shaped furcula (wishbone). The absence of the prefrontal bone and the non-diapsid skull allows ''Yanornis'' to be classified as an Ornithuromorpha, ornithuromorph, a member of a group of stem-birds which also includes the common ancestor of living birds.
