Jingmai O'Connor
Jingmai Kathleen O'Connor ( ''Zōu Jīngméi''; born August 26, 1983) is a paleontologist who works as a curator at the Field Museum in Chicago, Illinois. Biography O'Connor is from Pasadena, California. Her mother is a geologist. O'Connor says that while she was not a dinosaur enthusiast as a child, being present for her mother's geology fieldwork began her interest in the subject. She explains, "I enjoyed going to the field with her, collecting rocks, minerals, and fossils, and playing in the lab." O'Connor graduated from Occidental College after majoring in Geology and studying with Donald Prothero. While a student, she volunteered in the paleontology department of the Natural History Museum of Los Angeles County, working with Xiaoming Wang (paleontologist), Xiaoming Wang. She received a Ph.D. from the University of Southern California in 2009, studying ancient birds with Luis M. Chiappe and David Bottjer.

Sue (dinosaur)
Sue (stylized: SUE), officially designated FMNH PR 2081, is one of the largest, most extensive, and best preserved ''Tyrannosaurus rex'' fossils ever found, at over 90 percent recovered by bulk. FMNH PR 2081 was discovered on August 12, 1990, by American explorer and fossil collector Sue Hendrickson, after whom it is named. After ownership disputes were settled, Sue was auctioned in October 1997 for US$8.3million, one of the highest amounts ever paid for a dinosaur fossil. Sue is now a permanent feature at the Field Museum of Natural History in Chicago, Illinois. Discovery During the summer of 1990, a group of workers from the Black Hills Institute, located in Hill City, searched for fossils at the Cheyenne River Indian Reservation in western South Dakota near the city of Faith. By the end of the summer, the group had discovered '' Edmontosaurus'' bones and was ready to leave. However, a flat tire was discovered on their truck before the group could depart on August 12. ...

Bohaiornis
''Bohaiornis'' is a genus of enantiornithean dinosaurs. Fossils have been found from the Lower Cretaceous Jiufotang Formation of western Liaoning, China. The only known species, ''Bohaiornis guoi'', was named by Dongyu Hu, Li Li, Lianhaim Hou and Xing Xu in 2011 on the basis of a fully articulated and well-preserved skeleton of a sub-adult. This specimen, LPM (Liaoning Paleontological Museum) B00167, preserved two long, ribbon-like feathers attached to the tail rather than a fan of shorter pennaceous feathers. It was similar to the slightly older '' Eoenantiornis'', but much larger in size.

Quartz Crystal
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is, therefore, classified structurally as a framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used ...

Paleontological Society
The Paleontological Society, formerly the Paleontological Society of America, is an international organisation devoted to the promotion of paleontology. The Society was founded in 1908 in Baltimore, Maryland, and was incorporated in April 1968 in the District of Columbia. The Society publishes the bi-monthly ''Journal of Paleontology'' and the quarterly ''Paleobiology'', holds an annual meeting in the autumn in conjunction with the Geological Society of America The Geological Society of America (GSA) is a nonprofit organization dedicated to the advancement of the geosciences. History The society was founded in Ithaca, New York, in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hi ..., sponsors conferences and lectures, and provides grants and scholarships. The Society has five geographic sections—Pacific Coast (founded March 1911), North-Central (founded May 1974), Northeastern (founded March 1977), Southeastern (founded November 1979), Rocky Mountain ...

Mesozoic
The Mesozoic Era is the Era (geology), era of Earth's Geologic time scale, geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles such as the dinosaurs, and of Gymnosperm, gymnosperms such as cycads, ginkgoaceae and Araucariaceae, araucarian conifers; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of significant tectonic, climatic, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to the potential role of the amber trade in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found in the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within north ...

Enantiornithine
The Enantiornithes, also known as enantiornithines or enantiornitheans in literature, are a group of extinct avialans ("birds" in the broad sense), the most abundant and diverse group known from the Mesozoic era. Almost all retained teeth and clawed fingers on each wing, but otherwise looked much like modern birds externally. Over seventy species of Enantiornithes have been named, but some names represent only single bones, so it is likely that not all are valid. The Enantiornithes became extinct at the Cretaceous–Paleogene boundary, along with Hesperornithes and all other non-avian dinosaurs. Discovery and naming The first Enantiornithes to be discovered were incorrectly referred to modern bird groups. For example, the first known species of Enantiornithes, '' Gobipteryx minuta'', was originally considered a paleognath related to ostriches and tinamou. The Enantiornithes were first recognized as a distinct lineage, or "subclass" of birds, by Cyril A. Walker in 1981. Walke ...

Evolutionary Biology
Evolutionary biology is the subfield of biology that studies the evolutionary processes such as natural selection, common descent, and speciation that produced the diversity of life on Earth. In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the Modern synthesis (20th century), modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, and paleontology. The investigational range of current research has widened to encompass the genetic architecture of adaptation, molecular evolution, and the different forces that contribute to evolution, such as sexual selection, genetic drift, and biogeography. The newer field of evolutionary developmental biology ("evo-devo") investigates how embryogenesis is controlled, thus yielding a wider synthesis that integrates developmental biology with the fields of study covered by the earlier evolutionary synthesis.
