Palaeontology
Paleontology, also spelled as palaeontology or palæontology, is the scientific study of the life of the past, mainly but not exclusively through the study of fossils. Paleontologists use fossils as a means to classify organisms, measure geologic time, and assess the interactions between prehistoric organisms and their natural environment. While paleontological observations are known from at least the 6th century BC, the foundation of paleontology as a science dates back to the work of Georges Cuvier in 1796. Cuvier demonstrated evidence for the concept of extinction and how life of the past was not necessarily the same as that of the present. The field developed rapidly over the course of the following decades, and the French word ''paléontologie'' was introduced for the study in 1822, which was derived from the Ancient Greek word for "ancient" and words describing relatedness and a field of study. Further advances in the field accompanied the work of Charles Darwin who p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyrannosauroid
Tyrannosauroidea (meaning 'tyrant lizard forms') is a superfamily (or clade) of coelurosaurian theropod dinosaurs that includes the family Tyrannosauridae as well as more basal relatives. Tyrannosauroids lived on the Laurasian supercontinent beginning in the Jurassic Period. By the end of the Cretaceous Period, tyrannosauroids were the dominant large predators in the Northern Hemisphere, culminating in the gigantic ''Tyrannosaurus''. Fossils of tyrannosauroids have been recovered on what are now the continents of North America, Europe and Asia. If Megaraptora is part of Tyrannosauroidea, this would extend the distribution of the group to Australia and South America, and possible fragmentary remains of tyrannosauroids have also been reported from these continents. Tyrannosauroids were bipedal carnivores, as were most theropods, and were characterized by numerous skeletal features, especially of the skull and pelvis. Early in their existence, tyrannosauroids were small pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauropod
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include '' Apatosaurus'', '' Argentinosaurus'', '' Alamosaurus'', ''Brachiosaurus'', '' Camarasaurus'', '' Diplodocus,'' and '' Mamenchisaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. '' Isanosaurus'' and '' Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the g ...

Alvarezsaurid
Alvarezsauridae is a family of small, long-legged dinosaurs. Although originally thought to represent the earliest known flightless birds, they are now thought to be an early diverging branch of maniraptoran theropods. Alvarezsaurids were highly specialized. They had tiny but stout forelimbs, with compact, bird-like hands. Their skeletons suggest that they had massive breast and arm muscles, possibly adapted for digging or tearing. They had long, tube-shaped snouts filled with tiny teeth. They have been interpreted as myrmecophagous, adapted to prey on colonial insects such as termites, with the short arms acting as effective digging instruments to break into nests. '' Alvarezsaurus'', the type genus of the family, was named for the historian Gregorio Álvarez. History of study Bonaparte (1991) described the first alvarezsaurid, '' Alvarezsaurus calvoi'', from an incomplete skeleton found in Patagonia, Argentina. Bonaparte also named a family, Alvarezsauridae, to contain it. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dromaeosaurid
Dromaeosauridae () is a family (biology), family of feathered coelurosaurian Theropoda, theropod dinosaurs. They were generally small to medium-sized feathered carnivores that flourished in the Cretaceous period (geology), Period. The name Dromaeosauridae means 'running lizards', from Ancient Greek, Greek ('), meaning 'running at full speed', 'swift', and ('), meaning 'lizard'. In informal usage, they are often called raptors (after ''Velociraptor''), a term popularized by the film ''Jurassic Park (film), Jurassic Park''; several Genus, genera include the term "raptor" directly in their name, and popular culture has come to emphasize their bird-like appearance and speculated bird-like behavior. Dromaeosaurid fossils have been found across the globe in North America, Europe, Africa, Asia and South America, with some fossils giving credence to the possibility that they inhabited Australia as well. The earliest body fossils are known from the Early Cretaceous (145–140 million y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troodontid
Troodontidae is a clade of bird-like theropod dinosaurs from the Late Jurassic to Late Cretaceous. During most of the 20th century, troodontid fossils were few and incomplete and they have therefore been allied, at various times, with many dinosaurian lineages. More recent fossil discoveries of complete and articulated specimens (including specimens which preserve feathers, eggs, embryos, and complete juveniles), have helped to increase understanding about this group. Anatomical studies, particularly studies of the most primitive troodontids, like '' Sinovenator'', demonstrate striking anatomical similarities with ''Archaeopteryx'' and primitive dromaeosaurids, and demonstrate that they are relatives comprising a clade called Paraves. Evolution The oldest definitive troodontid known is '' Hesperornithoides'' from the Late Jurassic of Wyoming. The slightly older '' Koparion'' of Utah is only represented by a single tooth, and small maniraptoran teeth from the Middle Jurassic ...

Heptasteornis
''Heptasteornis'' is the name given to a dubious genus of alvarezsaurid dinosaur from the Late Cretaceous. The type (and only known) species is ''Heptasteornis andrewsi'', described as a presumed gigantic prehistoric owl in 1975. It was previously included in '' Elopteryx nopcsai'' and indeed the holotypes of both were believed to be from the same individual as they were discovered, and initially were assigned the same specimen number. This appears to be in error however (see below).Harrison & Walker (1975) The material was discovered in Romania by Franz Nopcsa, in the late Maastrichtian Sânpetru Formation ( Rognacian faunal stage, deposited c. 68 - 66 million years ago) of the Haţeg Basin in Transylvania. The scientific name means "C.W. Andrews' Transylvanian bird", after the namer of ''Elopteryx'', and Ancient Greek ''hepta'' (ἑπτά) "seven" + ''asty'' (άστυ) "city" + ''ornis'' (όρνις) "bird"; the Latin ''septum urbium'' or the German ''Siebenbürgen'' - mean ...

Mirischia
''Mirischia'' is an extinct genus of coelurosaurian theropod dinosaur from the Albian Stage (stratigraphy), stage (Early Cretaceous Geological period, Period) of Brazil. Discovery and naming In 2000 David Martill and Eberhard Frey reported the find of a small dinosaur fossil present in a chalk nodule, illegally acquired by the German Staatliches Museum für Naturkunde Karlsruhe from an illegal Brazilian fossil dealer who had indicated the piece had been uncovered in the Chapada do Araripe, specifically at Araripina, Pernambuco. In 2004 the type species ''Mirischia asymmetrica'' was named and described by Martill, Frey and Darren Naish. The generic name combines the Latin ''mirus'', 'wonderful', with "ischia", the Latinised plural of Ancient Greek, Greek ἴσχιον, ''ischion'', 'hip joint'. The specific name (zoology), specific name ''asymmetrica'' refers to the fact that in the specimen the left ischium differs from its right counterpart. The holotype, SMNK 2349 PAL, has its ...

Aristosuchus
''Aristosuchus'' is a genus of small coelurosaurian dinosaur whose name was derived from the Greek ἄριστος (meaning bravest, best, noblest) and ''σουχος'' (the Ancient Greek corruption of the name of the Egyptian crocodile-headed god Sobek). It shared many characteristics with birds. Discovery The type species, ''Aristosuchus pusillus'', was described in 1876 by Richard Owen and named ''Poekilopleuron pusillus''. The specific epithet means "small" in Latin. Harry Govier Seeley (1839–1909) gave it the name ''Aristosuchus'' in 1887. It was found in the Wealden Group dating to the Early Cretaceous (Barremian) in England, on the Isle of Wight, i.e. from about 125 million years ago. Description ''Aristosuchus'' was a bipedal, meat-eating (carnivorous) theropod dinosaur. This predator is thought to have been about and is estimated to have weighed about . According to Gregory S. Paul, its weight was . The femur of ''Aristosuchus'' has a wing-like anterior t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
