Jack Horner (paleontologist)
John Robert Horner (born June 15, 1946) is an American paleontologist most famous for describing '' Maiasaura'', providing the first clear evidence that some dinosaurs cared for their young. In addition to his paleontological discoveries, Horner served as the technical advisor for the first five ''Jurassic Park'' films, had a cameo appearance in '' Jurassic World'', and served as a partial inspiration for one of the lead characters of the franchise, Dr. Alan Grant. Horner studied at the University of Montana, although he did not complete his degree due to undiagnosed dyslexia, and was awarded a Doctorate in Science ''honoris causa''. He retired from Montana State University on July 1, 2016, although he claims to have been pushed out of the Museum of the Rockies after having married an undergraduate student and now teaches as a Presidential Fellow at Chapman University. Biography Horner was born and raised near Shelby, Montana. He was 8 years old when he found his first di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shelby, Montana

Dinosaur Egg
Dinosaur eggs are the organic vessels in which a dinosaurs, dinosaur embryo develops. When the first scientifically documented remains of non-avian dinosaurs were being described in England during the 1820s, it was presumed that dinosaurs had laid egg (biology), eggs because they were reptiles. In 1859, the first scientifically documented dinosaur egg fossils were discovered in France by Jean-Jacques Poech, although they were mistaken for giant bird eggs (birds were not yet recognized as dinosaurs at the time). The first scientifically recognized non-avian dinosaur egg fossils were discovered in 1923 by an American Museum of Natural History crew in Mongolia. Dinosaur eggshell can be studied in thin section and viewed under a microscope. The interior of a dinosaur egg can be studied using CAT scans or by gradually dissolving away the shell with acid. Sometimes the egg preserves the remains of the developing embryo inside. The oldest known dinosaur eggs and embryos are from ''Masso ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Maiasaura Embryo
''Maiasaura'' (from the Greek language, Greek ''μαῖα'', meaning "midwife" and ''σαύρα'', the feminine form of ''saurus'', meaning "reptile") is a large herbivorous saurolophine hadrosaurid ("duck-billed") dinosaur genus that lived in the area currently covered by the state of Montana and the Canada, Canadian province of Alberta, in the Upper Cretaceous Period (geology), Period (mid to late Campanian), from 86.3 to 70.6 million years ago.Horner, J.

American Academy Of Achievement
The American Academy of Achievement, colloquially known as the Academy of Achievement, is a nonprofit educational organization that recognizes some of the highest-achieving people in diverse fields and gives them the opportunity to meet one another. The academy also brings together the leaders with promising graduate students for mentorship. It hosts an International Achievement Summit, which ends with an awards ceremony, during which new members are inducted into the academy. History Founded in 1961 by ''Sports Illustrated'' and ''LIFE'' magazine photographer Brian Reynolds, the Academy of Achievement recognizes high achievers in public service, business, science and exploration, sports, and the arts. Reynolds established the academy after realizing that the famous people he photographed from different fields did not usually get to meet one another. A 1989 ''San Francisco Chronicle'' article called the organization "little-publicized but immensely powerful". According to ...

MacArthur Fellowship
The MacArthur Fellows Program, also known as the MacArthur Fellowship and colloquially called the "Genius Grant", is a prize awarded annually by the MacArthur Foundation, John D. and Catherine T. MacArthur Foundation to typically between 20 and 30 individuals working in any field who have shown "extraordinary originality and dedication in their creative pursuits and a marked capacity for self-direction" and are citizens or residents of the United States. According to the foundation's website, "the fellowship is not a reward for past accomplishments but rather an investment in a person's originality, insight, and potential", but it also says such potential is "based on a track record of significant accomplishments". The current prize is $800,000 paid over five years in quarterly installments. Previously, it was $625,000. This figure was increased from $500,000 in 2013 with the release of a review of the MacArthur Fellows Program. The award has been called "one of the most signifi ...

Lagerstätte
A Fossil-Lagerstätte (, from ''Lager'' 'storage, lair' '' Stätte'' 'place'; plural ''Lagerstätten'') is a sedimentary deposit that preserves an exceptionally high amount of palaeontological information. ''Konzentrat-Lagerstätten'' preserve a high concentration of fossils, while ''Konservat-Lagerstätten'' offer exceptional fossil preservation, sometimes including preserved soft tissues. ''Konservat-Lagerstätten'' may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying the decomposition of both gross and fine biological features until long after a durable impression was created in the surrounding matrix. ''Fossil-Lagerstätten'' spans geological time from the Neoproterozoic era to the present. Worldwide, some of the best examples of near-perfect fossilization are the Cambrian Maotianshan shales and Burgess Shale, the Ordovician Soom Shale, the Silurian Waukesha Biota, the Devonian Hunsrück Slates and Gogo Formation, the Ca ...

Bear Gulch Limestone
The Bear Gulch Limestone is a limestone-rich Lens (geology), geological lens in central Montana, renowned for the quality of its marine fossils from the late Mississippian (geology), Mississippian subperiod, about 324 million years ago. It is exposed over a number of outcrops northeast of the Big Snowy Mountains, and is often considered a component of the more widespread Heath Formation. The Bear Gulch Limestone reconstructs a diverse, though isolated, marine ecosystem which developed near the end of the Serpukhovian age in the Carboniferous period. It is a lagerstätte, a particular type of rock unit with exceptional fossil preservation of both articulated skeletons and soft tissues. Bear Gulch fossils include a variety of fish, invertebrates, and algae occupying a number of different habitats within a preserved shallow bay. Fish include a high diversity of unusual Chondrichthyes, chondrichthyans (cartilaginous fish) and one of the oldest known lampreys, along with other vertebrat ...
