Nodosaurus
''Nodosaurus'' (meaning "knobbed lizard") is a genus of herbivorous nodosaurid ankylosaurian dinosaur from the Late Cretaceous, the fossils of which are found exclusively in the Frontier Formation in Wyoming. Description ''Nodosaurus'' grew up to roughly long and it was an ornithischian dinosaur with bony dermal plates covering the top of its body, and it may have had spikes along its side as well. The dermal plates were arranged in bands along its body, with narrow bands over the ribs alternating with wider plates in between. These wider plates were covered in regularly arranged bony nodules, which give the animal its scientific name. In 2010 Paul estimated its length at 6 meters (20 ft) and its weight at 3.5 tonnes (3.85 short tons). It had four short legs, five-toed feet, a short neck, and a long, stiff, clubless tail. The head was narrow, with a pointed snout, powerful jaws, and small teeth. It perhaps ate soft plants, as it would have been unable to chew tough, fib ...

Nodosauridae
Nodosauridae is a family of ankylosaurian dinosaurs, from the Late Jurassic to the Late Cretaceous period in what is now North America, South America, Europe, and Asia. Description Nodosaurids, like their close relatives the ankylosaurids, were heavily armored dinosaurs adorned with rows of bony armor nodules and spines (osteoderms), which were covered in keratin sheaths. All nodosaurids, like other ankylosaurians, were medium-sized to large, heavily built, quadrupedal, herbivorous dinosaurs, possessing small, leaf-shaped teeth. Unlike ankylosaurids, nodosaurids lacked mace-like tail clubs, instead having flexible tail tips. Many nodosaurids had spikes projecting outward from their shoulders. One particularly well-preserved nodosaurid "mummy", known as the Suncor nodosaur (''Borealopelta markmitchelli''), preserved a nearly complete set of armor in life position, as well as the keratin covering and mineralized remains of the underlying skin, which indicate reddish dorsal pigmen ...

Nodosaurinae
Nodosaurinae is a subfamily of nodosaurid ankylosaurs from the Cretaceous of Europe, North America, and South America. The group is defined as the largest clade containing '' Nodosaurus textilis'' but not ''Hylaeosaurus armatus'', '' Mymoorapelta maysi'', or ''Polacanthus foxii'', and was formally named in 2021 by Madzia and colleagues, who utilized the name of Othenio Abel in 1919, who created the term to unite ''Ankylosaurus'', ''Hierosaurus'' and ''Stegopelta''. The name has been significantly refined in content since Abel first used it to unite all quadrupedal, plate-armoured ornithischians, now including a significant number of taxa from the Early Cretaceous through Maastrichtian of Europe, North America, and Argentina. Previous informal definitions of the group described the clade as all taxa closer to ''Panoplosaurus'', or ''Panoplosaurus'' and ''Nodosaurus'', than to the early ankylosaurs ''Sarcolestes'', ''Hylaeosaurus'', ''Mymoorapelta'' or ''Polacanthus'', which was refle ...

Acantholipan
''Acantholipan'' is a genus of herbivorous nodosaurid dinosaur from Mexico from the early Santonian age of the Late Cretaceous. It includes one species, ''Acantholipan gonzalezi.'' Discovery and naming In the north of Mexico, fragmentary fossils have been found of nodosaurids. A partial skeleton excavated at Los Primos near San Miguel in Coahuila, was described in 2011. When Rivera-Sylva and colleagues reported the discovery of this specimen, CPC 272, they initially considered it too fragmentary to name. Later it was judged that the remains were sufficiently distinct to be given a binomial name. In 2018, the type species ''Acantholipan gonzalezi'' was named by Héctor Eduardo Rivera-Sylva, Eberhard Frey, Wolfgang Stinnesbeck, Gerardo Carbot-Chanona, Iván Erick Sanchez-Uribe and José Rubén Guzmán-Gutiárrez. The generic name combines a Greek ''akanthos'', "spine", with ''lipan'', the usual Spanish designation of the '' Lépai-Ndé'', the "Gray People", a tribe of the Ap ...

Frontier Formation
The Frontier Formation is a sedimentary geological formation whose strata date back to the Late Cretaceous. The formation's extents are: northwest Colorado, southeast Idaho, southern Montana, northern Utah, and western Wyoming. It occurs in many sedimentary basins and uplifted areas. The formation is described by W.G. Pierce as thick, lenticular, grey sandstone, gray shale, carbonaceous shale, and bentonite. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, North America)."

Stegopelta
''Stegopelta'' (meaning "roofed shield") is a genus of struthiosaurin nodosaurid dinosaur. It is based on a partial skeleton from the latest Albian- earliest Cenomanian-age Lower and Upper Cretaceous Belle Fourche Member of the Frontier Formation of Fremont County, Wyoming, USA. History In 1905, Samuel Wendell Williston described FMNH UR88, a partial armored dinosaur skeleton consisting of a maxilla fragment, seven cervical and two dorsal vertebrae, part of a sacrum and both ilia, caudal vertebrae, parts of the scapulae, both humeral heads, portions of an ulna and both radii, a metacarpal, partial tibia, metatarsal, and armor including a shoulder spine and neck ring.Carpenter, K., and Kirkland, J.I.

Polacanthus
''Polacanthus'', deriving its name from the Ancient Greek polys-/πολύς- "many" and akantha/ἄκανθα "thorn" or "prickle", is an early armoured, spiked, plant-eating ankylosaurian dinosaur from the early Cretaceous period of England. In the genus ''Polacanthus'' several species have been named but only the type species ''Polacanthus foxii'' is today seen as valid. ''Polacanthus'' was a quadrupedal ornithischian or "bird-hipped" dinosaur. It lived 130 to 125 million years ago in what is now western Europe.Holtz, Thomas R. Jr. (2012) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,''https://www.geol.umd.edu/~tholtz/dinoappendix/appendix.html ''Polacanthus foxii'' was named after a find on the Isle of Wight in 1865. There are not many fossil remains of this creature, and some important anatomical features, such as its skull, are poorly known. Early depictions often gave it a very generic head as it was only known from the rear half o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Othniel Charles Marsh
Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American professor of Paleontology in Yale College and President of the National Academy of Sciences. He was one of the preeminent scientists in the field of paleontology. Among his legacies are the discovery or description of dozens of new species and theories on the origins of birds. Born into a modest family, Marsh was able to afford higher education thanks to the generosity of his wealthy uncle George Peabody. After graduating from Yale College in 1860 he travelled the world, studying anatomy, mineralogy and geology. He obtained a teaching position at Yale upon his return. From the 1870s to 1890s, he competed with rival paleontologist Edward Drinker Cope in a period of frenzied Western American expeditions known as the Bone Wars. Marsh's greatest legacy is the collection of Mesozoic reptiles, Cretaceous birds, and Mesozoic and Tertiary mammals that now constitute the backbone of the collections of Yale's Peabo ...

Ornithischian
Ornithischia () is an extinct order of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. The name ''Ornithischia'', or "bird-hipped", reflects this similarity and is derived from the Greek stem ' (), meaning "of a bird", and ' (), plural ', meaning "hip joint". However, birds are only distantly related to this group as birds are theropod dinosaurs. Ornithischians with well known anatomical adaptations include the ceratopsians or "horn-faced" dinosaurs (e.g. ''Triceratops''), the pachycephalosaurs or "thick-headed" dinosaurs, the armored dinosaurs (Thyreophora) such as stegosaurs and ankylosaurs, and the ornithopods. There is strong evidence that certain groups of ornithischians lived in herds, often segregated by age group, with juveniles forming their own flocks separate from adults. Some were at least partially covered in filamentous (hair- or feather- like) pelts, and there is much debate over whether these filaments foun ...
