Dueling Dinosaurs
The Dueling Dinosaurs or Montana Dueling Dinosaurs is a fossil specimen originating from the Hell Creek Formation of Montana. It consists of the fossilized skeletons of a tyrannosaur (generally considered a juvenile ''Tyrannosaurus, Tyrannosaurus rex'') and a ''Triceratops, Triceratops horridus'' entangled with one another, and entombed in sandstone. The "dueling" inference comes from the numerous injuries sustained by both dinosaurs, including a tooth from the tyrannosaur embedded within the ''Triceratops'', although it is not known whether they were actually buried fighting one another. Despite the scientific importance of the specimen, it remained obscure for decades due to a lengthy legal dispute over property rights to the specimen, which has since been resolved. The fossil is in the possession of and being studied by the North Carolina Museum of Natural Sciences, where it went on display in 2024. History The specimen was originally discovered in 2006 by ranchers Clayton P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dueling Dinosaurs Reconstruction
A duel is an arranged engagement in combat between two people, with matched weapons, in accordance with agreed-upon Code duello, rules. During the 17th and 18th centuries (and earlier), duels were mostly single combats fought with swords (the rapier and later the small sword), but beginning in the late 18th century in England, duels were more commonly fought using pistols. Fencing and shooting continued to co-exist throughout the 19th century. The duel was based on a Code of conduct, code of honor. Duels were fought not so much to kill the opponent as to gain "satisfaction", that is, to restore one's honor by demonstrating a willingness to risk one's life for it, and as such the tradition of dueling was originally reserved for the male members of nobility; however, in the modern era, it extended to those of the upper classes generally. On occasion, duels with swords or pistols were fought between women. Legislation against dueling goes back to the medieval period. The Fourth Co ...

Paleontology In Montana
Paleontology in Montana refers to paleontological research occurring within or conducted by people from the U.S. state of Montana. The fossil record in Montana stretches all the way back to the Precambrian. During the Late Precambrian, western Montana was covered by a warm, shallow sea where local bacteria formed stromatolites and bottom-dwelling marine life left tracks on the sediment that would later fossilize. This sea remained in place during the early Paleozoic, although withdrew during the Silurian and Early Devonian, leaving a gap in the local rock record until its return. This sea was home to creatures including brachiopods, conodonts, crinoids, fish, and trilobites. During the Carboniferous the state was home to an unusual cartilaginous fish fauna. Later in the Paleozoic the sea began to withdraw, but with a brief return during the Permian. During the Triassic Montana was again covered in a sea whose inhabitants are the state's only known fossils from this time. Much of ...

Cretaceous Fossil Record
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by th ...

Protoceratops
''Protoceratops'' (; ) is a genus of small protoceratopsid dinosaurs that lived in Asia during the Late Cretaceous, around 75 to 71 million years ago. The genus ''Protoceratops'' includes two species: ''P. andrewsi'' and the larger ''P. hellenikorhinus''. The former was described in 1923 with fossils from the Mongolian Djadokhta Formation, and the latter in 2001 with fossils from the Chinese Bayan Mandahu Formation. ''Protoceratops'' was initially believed to be an ancestor of ankylosaurians and larger ceratopsians, such as ''Triceratops'' and relatives, until the discoveries of other protoceratopsids. Populations of ''P. andrewsi'' may have evolved into ''Bagaceratops'' through anagenesis. ''Protoceratops'' were small ceratopsians, about long and in body mass. While adults were largely quadrupedal, juveniles had the capacity to walk around bipedally if necessary. They were characterized by a proportionally large skull, short and stiff neck, and neck frill. The frill was likel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velociraptor
''Velociraptor'' (; ) is a genus of small dromaeosaurid dinosaur that lived in Asia during the Late Cretaceous epoch, about 75 million to 71 million years ago. Two species are currently recognized, although others have been assigned in the past. The type species is ''V. mongoliensis''; fossils of this species have been discovered in the Djadochta Formation, Mongolia. A second species, ''V. osmolskae'', was named in 2008 for skull material from the Bayan Mandahu Formation, China. Smaller than other dromaeosaurids like ''Deinonychus'' and ''Achillobator'', ''Velociraptor'' was about long with a body mass between . It nevertheless shared many of the same anatomical features. It was a bipedal, feathered carnivore with a long tail and an enlarged sickle-shaped claw on each hindfoot, which is thought to have been used to tackle and restrain prey. ''Velociraptor'' can be distinguished from other dromaeosaurids by its long and low skull, with an upturned snout. ''Velociraptor'' (com ...

Fighting Dinosaurs
The Fighting Dinosaurs is a fossil specimen which was found in the Late Cretaceous Djadokhta Formation of Mongolia. It preserves a '' Protoceratops andrewsi'' and '' Velociraptor mongoliensis'' trapped in combat and provides direct evidence of predatory behavior in non- avian dinosaurs. The specimen was discovered in 1971 and has caused much debate as to how both animals came to be preserved together with relative completeness. Several hypotheses have been proposed, including a drowning scenario, burial by either dune collapse or sandstorm, or alternatively they were not buried simultaneously. History of discovery From 1963 to 1971, Polish- Mongolian paleontological expeditions were carried out in the Gobi Desert with the objective of fossil-finding. The expedition of 1971 visited several localities of the Djadokhta and Nemegt formations, discovering the lower beds of the latter. In that year on August 3, during the fieldwork of a team composed of paleontologists Tom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specimens Of Tyrannosaurus
''Tyrannosaurus'' is one of the most iconic dinosaurs and is known from numerous specimens, some of which have individually acquired notability due to their scientific significance and media coverage. Specimen data ''Manospondylus'': AMNH 3982 The first-named fossil specimen which can be attributed to ''Tyrannosaurus rex'' consists of two partial vertebrae (one of which has been lost) found by Edward Drinker Cope in 1892. Cope believed that they belonged to an "agathaumid" ( ceratopsid) dinosaur, and named them ''Manospondylus gigas'', meaning "giant porous vertebra" in reference to the numerous openings for blood vessels he found in the bone. The ''M. gigas'' remains were later identified as those of a theropod rather than a ceratopsid, and H.F. Osborn recognized the similarity between ''M. gigas'' and ''Tyrannosaurus rex'' as early as 1917. However, due to the fragmentary nature of the ''Manospondylus'' vertebrae, Osborn did not synonymize the two genera. ''Dynamosaurus'': ...
