"Archaeoraptor" is the generic name informally assigned in 1999 to a fossil from China in an article published in National Geographic magazine. The magazine claimed that the fossil was a "missing link" between birds and terrestrial theropoddinosaurs. Even prior to this publication there had been severe doubts about the fossil's authenticity. It led to a scandal when it was definitely proven to be a forgery through further scientific study. The forgery was constructed from rearranged pieces of real fossils from different species. Zhou et al. found that the head and upper body actually belong to a specimen of the primitive fossil bird Yanornis. 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. The "Archaeoraptor" scandal has ongoing ramifications. The scandal brought attention to illegal fossil deals conducted in China. It also highlighted the need for close scientific scrutiny of purported "missing links" published in journals which are not peer-reviewed. The fossil scandal has been used by creationists to cast doubt on evolutionary theory. Although "Archaeoraptor" was a forgery, many true examples of feathered dinosaurs have been found and demonstrate the evolutionary connection between birds and other theropods. (Read more...)
... that Irritator is only known from a skull that was badly obscured by plaster which was added by the commercial fossil-collecting fossil-poachers who illegally sold it in hopes of making the fossil look more complete and valuable?
... that rhynchosaurs had unique teeth that were modified into broad tooth plates?
... that a trackway produced by an unknown crocodyliform that measured approximately 12 meters in length was uncovered in the Galve region of Spain?
"It is well known, that on the Ohio, and in many parts of America further north, tusks, grinders, and skeletons of unparalleled magnitude are found in great numbers, some lying on the surface of the earth, and some a little below it ... But to whatever animal we ascribe these remains, it is certain that such a one has existed in America, and that it has been the largest of all terrestrial beings."
A composite picture of Beipiaosaurus above [image from Xu et al. (2009)], and a close-up of its neck region is shown at bottom left of the composite. The image at bottom right in the composite is the tail of another specimen. Scale bar in A = 50 mm]. Beipiaosaurus. Beipiaosaurus is a genus of therizinosauroidtheropoddinosaur. The discovery of Beipiaosaurus, which translates as "Beipiao lizard" after a city in China near the location of its discovery, was announced in the May 27, 1999, issue of the journal Nature. These fossils were found in Liaoning Province, China and have been dated to the Early CretaceousPeriod, about 125 million years ago. It is known from a single species, B. inexpectus, named for "the surprising features in this animal.". A significant number of fossilized bones for this species were recovered, including: cranial fragments, a mandible, three cervical vertebrae, four dorsal vertebrae, a caudal vertebra, the scapula and scapulacoracoid, a complete forelimb, and a complete pelvis with hindlimb. A second specimen was described by Xu et al. in 2009, which preserved a complete skull as well as a significant covering of unique, elongated feathers.
