Protarchaeopteryx
''Protarchaeopteryx'' (meaning "before ''Archaeopteryx''") is a genus of turkey-sized feathered theropod dinosaur from China.Ji, Q., and Ji, S. (1997). "Protarchaeopterygid bird (''Protarchaeopteryx'' gen. nov.) – fossil remains of archaeopterygids from China." ''Chinese Geology'', 238: 38–41. Known from the Jianshangou bed of the Yixian Formation, it lived during the early Aptian age of the Early Cretaceous, approximately 124.6 million years ago.Zhou, Z. (2006). "Evolutionary radiation of the Jehol Biota: chronological and ecological perspectives." ''Geological Journal'', 41: 377–393. It was probably a herbivore or omnivore, although its hands were very similar to those of small carnivorous dinosaurs. It appears to be one of the most basal members of the Oviraptorosauria, closely related to ''Incisivosaurus'', or a taxon slightly less closely related to birds than oviraptorosaurs were.

Incisivosaurus
''Incisivosaurus'' ("incisor lizard") is a genus of small, probably herbivorous theropod dinosaurs from the early Cretaceous Period of what is now the People's Republic of China. The first specimen to be described (by Xu ''et al.'' in 2002), IVPP V13326, is a skull that was collected from the lowermost levels (the fluvial Lujiatun beds) of the Yixian Formation (dating to the Barremian stage about 126 million years ago) in the Sihetun area, near Beipiao, Beipiao City, in western Liaoning Province. The most significant, and highly unusual, characteristic of this dinosaur is its apparent adaptation to an herbivorous or omnivorous lifestyle. It was named for its prominent, rodent-like front teeth, which show wear patterns commonly found in plant-eating dinosaurs. The specific name (zoology), specific name ''gauthieri'' honors Jacques Gauthier, Dr. Jacques Gauthier, a pioneer of the phylogenetic method of classification.

Oviraptorosaurs
Oviraptorosaurs ("egg thief lizards") are a group of feathered maniraptoran dinosaurs from the Cretaceous Period of what are now Asia and North America. They are distinct for their characteristically short, beaked, parrot-like skulls, with or without bony crests atop the head. They ranged in size from ''Caudipteryx'', which was the size of a turkey, to the 8-meter-long, 1.4-ton ''Gigantoraptor''. The group (along with all maniraptoran dinosaurs) is close to the ancestry of birds. Some researchers such as Maryanska ''et al'' (2002) and Osmólska ''et al.'' (2004) have proposed that they may represent primitive flightless birds.Osmólska, Halszka, Currie, Philip J., Brasbold, Rinchen (2004) "The Dinosauria" Weishampel, Dodson, Osmólska. "Chapter 8 Oviraptorosauria" University of California Press. The most complete oviraptorosaur specimens have been found in Asia. The North American oviraptorosaur record is sparse.Varricchio, D.

Timeline Of Oviraptorosaur Research
This timeline of oviraptorosaur research is a chronological listing of events in the history of paleontology focused on the oviraptorosaurs, a group of beaked, bird-like theropod dinosaurs. The early history of oviraptorosaur paleontology is characterized by taxonomic confusion due to the unusual characteristics of these dinosaurs. When initially described in 1924 ''Oviraptor'' itself was thought to be a member of the Ornithomimidae, popularly known as the "ostrich" dinosaurs, because both taxa share toothless beaks. Early caenagnathid oviraptorosaur discoveries like ''Caenagnathus'' itself were also incorrectly classified at the time, having been misidentified as birds. The hypothesis that caenagnathids were birds was questioned as early as 1956 by Romer, but not corrected until Osmolska formally reclassified them as dinosaurs in 1976. Meanwhile, the classification of ''Oviraptor'' as an ornithomimid persisted unquestioned by researchers like Romer and Steel until the early ...

Feathered Dinosaurs
A feathered dinosaur is any species of dinosaur possessing feathers. While this includes all species of birds, there is a hypothesis that many, if not all non-avian dinosaur species also possessed feathers in some shape or form. It has been suggested that feathers had originally functioned as thermal insulation, as it remains their function in the down feathers of infant birds today, prior to their eventual modification in birds into structures that support flight. Since scientific research began on dinosaurs in the early 1800s, they were generally believed to be closely related to modern reptiles, such as lizards. The word ''dinosaur'' itself, coined in 1842 by paleontologist Richard Owen, comes from the Greek for 'terrible lizard'. This view began to shift during the so-called dinosaur renaissance in scientific research in the late 1960s, and by the mid-1990s significant evidence had emerged that dinosaurs were much more closely related to birds, which descended directly ...

Geological Museum Of China
The Geological Museum of China (), built in 1916, is a geological museum, boasting 200 thousand specimens. This museum is located in the Xisi area of Beijing and opened on October 1, 1959. It is the earliest geological scientific museum of China. At present, the Geological Museum of China has more than 100,000 geological specimens. Many of them are precious items reputed as "National Treasures", such as "the Giant Shandong Dinosaur"('' Shantungosaurus'') fossil, the most complete dinosaur fossils extant in the world excavated from Liaoning; the fossils of primitive birds that were found in the west of Liaoning Province, which has the essential values to the research on birds of the area; the teeth fossils of Yunnan Yuanmou Man, which shifts the appearance of human beings in China to a much more earlier time; the stoneware, stone pearls, bone needles and bone decoration unearthed from the site of the Upper Cave man at Zhoukoudian in Beijing; a cinnabar crystal of 237 grams that ...

Philip J
Philip, also Phillip, is a male given name, derived from the Greek (''Philippos'', lit. "horse-loving" or "fond of horses"), from a compound of (''philos'', "dear", "loved", "loving") and (''hippos'', "horse"). Prominent Philips who popularized the name include kings of Macedonia and one of the apostles of early Christianity. ''Philip'' has many alternative spellings. One derivation often used as a surname is Phillips. It was also found during ancient Greek times with two Ps as Philippides and Philippos. It has many diminutive (or even hypocoristic) forms including Phil, Philly, Lip, Pip, Pep or Peps. There are also feminine forms such as Philippine and Philippa.
