Panoplosaurini
Panoplosaurini (derived from ''Panoplosaurus'', "all shield reptile") is a clade of nodosaurid ankylosaurs from the Cretaceous of North America and South America. The group is defined as the largest clade containing ''Panoplosaurus mirus'', but not '' Nodosaurus textilis'' or '' Struthiosaurus austriacus'', and was named in 2021 by Madzia and colleagues for the group found in many previous analyses, both morphological and phylogenetic. Panoplosaurini includes not only the Late Cretaceous ''Panoplosaurus'', ''Denversaurus'' and ''Edmontonia'', but also the mid Cretaceous ''Animantarx'' and ''Texasetes'', as well as ''Patagopelta''. However, in the study describing it, its authors only placed it as a nodosaurine outside Panoplosaurini. The approximately equivalent clade Panoplosaurinae, named in 1929 by Franz Nopcsa, but was not significantly used until Robert Bakker reused the name in 1988, alongside the new clades Edmontoniinae and Edmontoniidae, which were considered to unite ''Pan ...

Panoplosaurus Mirus
''Panoplosaurus'' is a genus of armoured dinosaur from the Late Cretaceous of Alberta, Canada. Few specimens of the genus are known, all from the middle Campanian of the Dinosaur Park Formation, roughly 76 to 75 million years ago. It was first discovered in 1917, and named in 1919 by Lawrence Lambe, named for its extensive armour, meaning "well-armoured lizard". ''Panoplosaurus'' has at times been considered the proper name for material otherwise referred to as ''Edmontonia'', complicating its phylogenetic and ecological interpretations, at one point being considered to have existed across Alberta, New Mexico and Texas, with specimens in institutions from Canada and the United States. The skull and skeleton of ''Panoplosaurus'' are similar to its relatives, but have a few significant differences, such as the lumpy form of the skull osteoderms, a completely fused shoulder blade, and regularly shaped plates on its neck and body lacking prominent spines. It was a quadrupedal animal, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Edmontonia
''Edmontonia'' is a genus of panoplosaurin nodosaurid dinosaur from the Late Cretaceous Period. It is part of the Nodosauridae, a family within Ankylosauria. It is named after the Edmonton Formation (now the Horseshoe Canyon Formation in Canada), the unit of rock where it was found. Description Size and general build ''Edmontonia'' was bulky, broad and tank-like. Its length has been estimated at about 6.6 m (22 ft). In 2010, Gregory S. Paul considered both main ''Edmontonia'' species, ''E. longiceps'' and ''E. rugosidens'', to be equally long at six metres and weigh three tonnes.Paul, G.S., 2010, ''The Princeton Field Guide to Dinosaurs'', Princeton University Press p. 238 ''Edmontonia'' had small, oval ridged bony plates on its back and head and many sharp spikes along its sides. The four largest spikes jutted out from the shoulders on each side, the second of which was split into subspines in ''E. rugosidens'' specimens. Its skull had a pear-like shape when viewed ...

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 ...

Texasetes
''Texasetes'' (meaning "Texas resident") is a genus of ankylosaurian dinosaurs from the late Lower Cretaceous of North America. This poorly known genus has been recovered from the Paw Paw Formation (late Albian) near Haslet, Tarrant County, Texas, which has also produced the nodosaurid ankylosaur ''Pawpawsaurus''. Discovery and taphonomy 5 miles south of Haslet near Fort Worth, Texas, fossils of an ankylosaurid were excavated from strata of the upper Albian rocks from Lower Cretaceous in the Pawpaw Formation.Coombs Jr, W. P. (1995). A nodosaurid ankylosaur (Dinosauria: Ornithischia) from the Lower Cretaceous of Texas. ''Journal of vertebrate Paleontology'', ''15''(2), 298-312. The fossils would later become the holotype ( USNM 337987) of ''Texasetes,'' consisting of a skull fragment, 2 teeth, 5 cervical centra, 3 sacral centra, 16 caudal centra, partial scapulacoracoids, fragmentary pelvis, humeri, femora, tibiae, proximal ulnae, proximal radii, left metacarpal IV, left me ...

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 ...

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 ...

Peloroplites
''Peloroplites'' (meaning “monstrous heavy one”) is a monospecific genus of nodosauridae, nodosaurid dinosaur from Utah that lived during the Late Cretaceous (Cenomanian to lower Turonian stage, 98.2 to 93 Ma) in what is now the Mussentuchit Member of the Cedar Mountain Formation. The type and only species, ''Peloroplites cedrimontanus'', is known from a partial skull and postcrania, postcranial skeleton. It was named in 2008 by Kenneth Carpenter and colleagues. ''Peloroplites'' was 6 metres (20 feet) long and weighed 2 tonnes (4,410 lbs), making it one of the largest known nodosaurids, and came from a time when ankylosauridae, ankylosaurids and nodosaurids were attaining large sizes.Paul, G.S., 2016, ''The Princeton Field Guide to Dinosaurs 2nd Edition'', Princeton University Press Discovery and Naming In 2001, a skeleton of a large nodosauridae, nodosaurid from the Cedar Mountain Formation in Emery County, Utah, Emery County, Utah was mentioned by Burge and Bird in a publi ...

Patagopelta
''Patagopelta'' (meaning "Patagonian shield") is an extinct genus of nodosaurine dinosaur from the Late Cretaceous (upper Campanian–lower Maastrichtian) Allen Formation of Argentina. The genus contains a single species, ''P. cristata'', known from a partial skeleton. ''Patagopelta'' is a very small ankylosaur, comparable in size to the dwarf nodosaurid '' Struthiosaurus'', about long. Discovery and naming The ''Patagopelta'' fossil material was found in sediments of the Allen Formation (Salitral Moreno locality) near General Roca, Río Negro Province, Argentina. This locality is dated to the upper Campanian to lower Maastrichtian ages of the Late Cretaceous period. The first remains were described in 1996 and often appeared in the literature as the "Argentinian ankylosaur". The fossil material consists of various osteoderms, a tooth, dorsal and caudal vertebrae, and femora. The ''Patagopelta'' holotype specimen, MPCA-SM-78, is represented by a cervical half-ring element. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ahshislepelta
''Ahshislepelta'' (meaning "Ah-shi-sle-pah Wash shield") is a monotypic taxon, monospecific genus of ankylosauria, ankylosaur dinosaur from New Mexico that lived during the Late Cretaceous (late Campanian stage, 74.5 Ma) in what is now the Hunter Wash Member of the Kirtland Formation. The type and only species, ''Ahshislepelta minor'', is known only from an incomplete postcrania, postcranial skeleton of a small subadult or adult individual. It was named in 2011 in archosaur paleontology, 2011 by Michael Burns and Robert M. Sullivan. Based on the size of the humerus, ''Ahshislepelta'' is larger than ''Pinacosaurus, Pinacosaurus mephistocephalus'' but smaller than ''Talarurus'' and ''Pinacosaurus, Pinacosaurus grangeri''. Discovery and naming In 2005, a partial postcranial skeleton of an ankylosauria, ankylosaur was discovered from the Hunter Wash Member in the lower part of the Kirtland Formation, New Mexico at the Ah-shi-sle-pah Wilderness Study Area. The specimen was later colle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
