Name two that have been proved to be frauds.

Exactly 1 year ago, paleontologists were abuzz about photos of a so-called “feathered dinosaur,” which were passed around the halls at the annual meeting of the Society of Vertebrate Paleontology. The Sinosauropteryx specimen from the Yixian Formation in China made the front page of The New York Times, and was viewed by some as confirming the dinosaurian origins of birds. But at this year’s vertebrate paleontology meeting in Chicago late last month, the verdict was a bit different: The structures are not modern feathers, say the roughly half-dozen Western paleontologists who have seen the specimens. ...Paleontologist Larry Martin of Kansas University, Lawrence, thinks the structures are frayed collagenous fibers beneath the skin-and so have nothing to do with birds. — Ann Gibbons, “Plucking the Feathered Dinosaur,” Science, vol. 278, no. 5341, 14 November 1997, pp. 1229 - 1230
rior to the publication of the article “Dinosaurs Take Wing” in the July 1998 National Geographic, Lou Mazzatenta, the photographer for Sloan’s article, invited me to the National Geographic Society to review his photographs of Chinese fossils and to comment on the slant being given to the story. At that time, I tried to interject the fact that strongly supported alternative viewpoints existed to what National Geographic intended to present, but it eventually became clear to me that National Geographic was not interested in anything other than the prevailing dogma that birds evolved from dinosaurs.
Sloan’s article takes the prejudice to an entirely new level and consists in large part of unverifiable or undocumented information that “makes” the news rather than reporting it. His bald statement that “we can now say that birds are theropods just as confidently as we say that humans are mammals” is not even suggested as reflecting the views of a particular scientist or group of scientists, so that it figures as little more than editorial propagandizing. This melodramatic assertion had already been disproven by recent studies of embryology and comparative morphology, which, of course, are never mentioned.
More importantly, however, none of the structures illustrated in Sloan’s article that are claimed to be feathers have actually been proven to be feathers. Saying that they are is little more than wishful thinking that has been presented as fact. The statement on page 103 that “hollow, hairlike structures characterize protofeathers” is nonsense considering that protofeathers exist only as a theoretical construct, so that the internal structure of one is even more hypothetical.
The hype about feathered dinosaurs in the exhibit currently on display at the National Geographic Society is even worse, and makes the spurious claim that there is strong evidence that a wide variety of carnivorous dinosaurs had feathers. A model of the undisputed dinosaur Deinonychus and illustrations of baby tyrannosaurs are shown clad in feathers, all of which is simply imaginary and has no place outside of science fiction.
