Uteodon
''Uteodon'' (meaning " Ute tooth") is a genus of herbivorous iguanodontian dinosaur. It is a basal iguanodontian which lived during the late Jurassic period (Tithonian age) in what is now Uintah County, Utah. It is known from the middle of the Brushy Basin Member, Morrison Formation. The genus was named by Andrew T. McDonald in 2011 and the type species is ''U. aphanoecetes''. it has also been reported from portugal. History The holotype specimen, CM 11337 (a virtually complete skeleton minus the skull and tail), was assigned to '' Camptosaurus medius'' (Marsh, 1894) by Charles W. Gilmore in 1925. When ''C. medius'' was synonymised with ''Camptosaurus dispar'' in 1980, G.S. Paul (2010) "''The Princeton Field Guide to Dinosaurs''". (Page 284). the holotype was seen to probably represent a new, then unnamed, species of ''Camptosaurus''. The species ''Camptosaurus aphanoecetes'' was first described in 2008 by Carpenter and Wilson. In 2011, it was assigned to the new genus ''Ut ...

Camptosaurus
''Camptosaurus'' ( ) is a genus of plant-eating, beaked ornithischian dinosaurs of the Late Jurassic period of western North America and possibly also Europe. The name means 'flexible lizard' ( Greek (') meaning 'bent' and (') meaning 'lizard'). Description ''Camptosaurus'' is a relatively heavily built form, with robust hindlimbs and broad feet, still having four toes. Due to the separate status of ''Uteodon'' it has become problematic which material from the Morrison Formation belongs to ''Camptosaurus''. The specimens with certainty belonging to ''Camptosaurus dispar'', from Quarry 13, have been recovered from very deep layers, probably dating to the Callovian- Oxfordian. The largest fragments from later strata indicate adult individuals more than long, and at the hips. The Quarry 13 individuals are smaller though. They have been described as reaching 6 meters (19.7 feet) in length and 785 – 874 kg in weight.Foster, J. (2007). "''Camptosaurus dispar''." ...

Cumnoria
''Cumnoria'' is a genus of herbivorous iguanodontian dinosaur. It was a basal iguanodontian that lived during the Late Jurassic period (Kimmeridgian age) in what is now Oxfordshire, United Kingdom. Description The holotype of ''Cumnoria'' is of a rather small bipedal animal with a slender build. about 3.5 metres (11.4 feet) long, The specimen is probably that of a juvenile though. History of discovery ''Cumnoria'' is known from the holotype OXFUM J.3303, a partial skull and postcranium, recovered from the lower Kimmeridge Clay Formation, in the Chawley Brick Pits, Cumnor Hurst. Workers at first discarded the remains on a dump heap, but one of them later collected the bones in a sack and showed them to Professor George Rolleston, an anatomist at the nearby Oxford University. Rolleston in turn brought them to the attention of palaeontologist Professor Joseph Prestwich who in 1879 reported them as a new species of ''Iguanodon'', though without actually coining a species n ...

Dry Mesa Quarry
The Dry Mesa Dinosaur Quarry is situated in southwestern Colorado, United States, near the town of Delta. Its geology forms a part of the Morrison Formation and has famously yielded a great diversity of animal remains from the Jurassic Period, among them ''Ceratosaurus'', '' Supersaurus'', and ''Torvosaurus''. The quarry is found within the Uncompahgre National Forest. History In 1971, a large theropod phalanx (''Torvosaurus'' ''tanneri'') was discovered at Dry Mesa by Ed and Vivian Jones of Delta, Colorado. The find was reported to James A. Jensen of Brigham Young University (BYU) who commenced quarrying operations in 1972. In 1973, Brigham Young University cooperated with producer Steve Linton and director John Linton in order to produce '' The Great Dinosaur Discovery'', a 1-hour-long color documentary showing Jensen's on-site finds in Dry Mesa. First released on November 13, 1973, in local "Egyptian Theater" in Delta, and subsequently aired on several USA TV channels, ''The ...

Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morrison Formation
The Morrison Formation is a distinctive sequence of Upper Jurassic sedimentary rock found in the western United States which has been the most fertile source of dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone, and limestone and is light gray, greenish gray, or red. Most of the fossils occur in the green siltstone beds and lower sandstones, relics of the rivers and floodplains of the Jurassic period. It is centered in Wyoming and Colorado, with outcrops in Montana, North Dakota, South Dakota, Nebraska, Kansas, the panhandles of Oklahoma and Texas, New Mexico, Arizona, Utah, and Idaho. Equivalent rocks under different names are found in Canada. It covers an area of 1.5 million square kilometers (600,000 square miles), although only a tiny fraction is exposed and accessible to geologists and paleontologists. Over 75% is still buried under the prairie to the east, and much of its western paleogeographic extent was eroded during exhum ...

Dryosaurus
''Dryosaurus'' ( , meaning 'tree lizard', Greek ' () meaning 'tree, oak' and () meaning 'lizard'; the name reflects the forested habitat, not a vague oak-leaf shape of its cheek teeth as is sometimes assumed) is a genus of an ornithopod dinosaur that lived in the Late Jurassic period. It was an iguanodont (formerly classified as a hypsilophodont). Fossils have been found in the western United States and were first discovered in the late 19th century. '' Valdosaurus canaliculatus'' and '' Dysalotosaurus lettowvorbecki'' were both formerly considered to represent species of ''Dryosaurus''. Description Based on known specimens, they had been estimated to have reached up to long and to have weighed up to . However, as no known adult specimens of the genus have been found, the adult size remains unknown. In 2018, the largest specimen (CM 1949) was concluded to be from another species; revising the identity of this specimen put the previous research on size and growth into question. ...

Tenontosaurus
''Tenontosaurus'' ( ; ) is a genus of medium- to large-sized ornithopod dinosaur. It was a relatively medium sized ornithopod, reaching in length and in body mass. It had an unusually long, broad tail, which like its back was stiffened with a network of bony tendons. The genus is known from the late Aptian to Albian ages of the Early Cretaceous period sediments of western North America, dating between 115 and 108 million years ago. It contains two species, ''Tenontosaurus tilletti'' (described by John Ostrom in 1970) and ''Tenontosaurus dossi'' (described by Winkler, Murry, and Jacobs in 1997). Many specimens of ''T. tilletti'' have been collected from several geological formations throughout western North America. ''T. dossi'' is known from only a handful of specimens collected from the Twin Mountains Formation of Parker County, Texas. History of discovery The first ''Tenontosaurus'' fossil was found in Big Horn County, Montana by an American Museum of Natural Hist ...

The Princeton Field Guide To Dinosaurs
''The Princeton Field Guide to Dinosaurs'' is a reference work on dinosaurs written by the paleontologist and paleoartist Gregory S. Paul. It was first published by Princeton University Press in 2010. In the United Kingdom it was published by A & C Black under the title ''Dinosaurs: A Field Guide''. An updated second edition was released in 2016. The book was well-received upon its release but garnered a mixed reception among paleontologists, who generally praised the large number of skeletal and life reconstructions throughout the book but questioned Paul's at times unorthodox approach to dinosaur taxonomy. Format ''The Princeton Field Guide to Dinosaurs'' was the first in the line of field guides published by Princeton University Press to be on an extinct (and thus not actually observable in the field) group of organisms. The book is a reference work on dinosaurs envisioned to be "in the style of a field guide". The book contains information on a wide assortment of dinosaur ...
