Larry Martin
Larry Dean Martin (December 8, 1943 – March 9, 2013) was an American vertebrate paleontologist and curator of the Natural History Museum and Biodiversity Research Center at the University of Kansas. Among Martin's work is research on the Triassic reptile '' Longisquama'' and theropod dinosaur (or fossil bird) ''Caudipteryx'' and ''Dakotaraptor ''Dakotaraptor'' (meaning “thief from Dakota”) is a potentially chimaeric genus of large dromaeosaurid theropod dinosaur that lived in North America during the Late Cretaceous period. The remains have been found in the Maastrichtian stage of ...''. According to the University of Kansas, he "has been a leading opponent of the theory that birds are 'living dinosaurs.'" Later he acknowledged a correlation and further contributed. He has also appeared in a few television documentaries about dinosaurs, including '' Jurassic Fight Club''. He died of cancer at the age of 69 on March 9, 2013, after a long battle with the disease. Refe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleontologist
Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, ( gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curator
A curator (from la, cura, meaning "to take care") is a manager or overseer. When working with cultural organizations, a curator is typically a "collections curator" or an "exhibitions curator", and has multifaceted tasks dependent on the particular institution and its mission. In recent years the role of curator has evolved alongside the changing role of museums, and the term "curator" may designate the head of any given division. More recently, new kinds of curators have started to emerge: "community curators", "literary curators", " digital curators" and " biocurators". Collections curator A "collections curator", a "museum curator" or a "keeper" of a cultural heritage institution (e.g., gallery, museum, library or archive) is a content specialist charged with an institution's collections and involved with the interpretation of heritage material including historical artifacts. A collections curator's concern necessarily involves tangible objects of some sort—artwork, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago (Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longisquama
''Longisquama'' is a genus of extinct reptile. There is only one species, ''Longisquama insignis'', known from a poorly preserved skeleton and several incomplete fossil impressions from the Middle to Late Triassic Madygen Formation in Kyrgyzstan. It is known from the type fossil specimen, slab and counterslab (PIN 2548/4 and PIN 2584/5) and five referred specimens of possible integumentary appendages (PIN 2584/7 through 9). All specimens are in the collection of the Paleontological Institute of the Russian Academy of Sciences in Moscow. ''Longisquama'' means "long scales"; the specific name ''insignis'' refers to its small size. The ''Longisquama'' holotype is notable for a number of long structures that appear to grow from its skin. The current opinion is that ''Longisquama'' is an ambiguous diapsid and has no bearing on the origin of birds. History Interpretation Researchers Haubold and Buffetaut believed that the structures were long, modified scales attached in pairs to ...

Theropod
Theropoda (; ), whose members are known as theropods, is a dinosaur clade that is characterized by hollow bones and three toes and claws on each limb. Theropods are generally classed as a group of saurischian dinosaurs. They were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores and omnivores. Theropods first appeared during the Carnian age of the late Triassic period 231.4 million years ago ( Ma) and included all the large terrestrial carnivores from the Early Jurassic until at least the close of the Cretaceous, about 66 Ma. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living species. Biology Diet and teeth Theropods exhibit a wide range of diets, from insectivores to herbivores and carnivores. Strict carnivory has always been considered the ancestral diet for theropods as a group, and a wider variety of diets was historically considered a ch ...

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caudipteryx
''Caudipteryx'' (which means "tail feather") is a genus of peacock-sized theropod dinosaurs that lived in the Barremian age of the early Cretaceous (about 124.6 million years ago). They were feathered and extremely birdlike in their overall appearance, to the point that some paleontologists think it was a bird. Two species have been described: ''C. zoui'' (the type species), in 1998, and ''C. dongi'', in 2000. ''Caudipteryx'' fossils were first discovered in the Yixian Formation of the Sihetun area of Liaoning Province, northeastern China in 1997. Description ''Caudipteryx'', like many other maniraptorans, has a mix of reptile- and bird-like anatomical features.Witmer, L.M. (2005). “The Debate on Avian Ancestry; Phylogeny, Function and Fossils”, ''Mesozoic Birds: Above the Heads of Dinosaurs'' : 3–30. It had a short, boxy skull with a beak-like snout that retained only a few tapered teeth in the front of the upper jaw. It had a stout trunk, long legs and was proba ...

Dakotaraptor
''Dakotaraptor'' (meaning “thief from Dakota”) is a potentially chimaeric genus of large dromaeosaurid theropod dinosaur that lived in North America during the Late Cretaceous period. The remains have been found in the Maastrichtian stage of the Hell Creek Formation, dated to the very end of the Mesozoic era, making ''Dakotaraptor'' one of the last surviving dromaeosaurids. The remains of ''D. steini'' were discovered in a multi-species bonebed. Elements of the holotype and referred specimens were later found to belong to trionychid turtles, and further analysis of potential non-dromaeosaurid affinities of the holotype and referred material have not yet been conducted. Phylogenetic analyses of ''D. steini'' place it in a variety of positions in the Dromaeosauridae. Discovery and naming In 2005, paleontologist Robert DePalma in Harding County, South Dakota discovered a fluvial bonebed bearing the remains of a variety of dinosaurian and non-dinosaurian remains, which yielded ...
