Edmontoniidae
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 ' ...

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 ...

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] |

Denversaurus
''Denversaurus'' (meaning "Denver lizard") is a genus of panoplosaurin nodosaurid dinosaur from the Late Cretaceous (late Maastrichtian) of western North America. Although at one point treated as a junior synonym of ''Edmontonia'' by some taxonomists, current research indicates that it is a distinct nodosaurid genus. Discovery and naming In 1922, Philip Reinheimer, a collector and technician employed by the Colorado Museum of Natural History, the predecessor of the present Denver Museum of Nature and Science, near the Twito Ranch in Corson County, South Dakota discovered the fossil of an ankylosaurian in a Maastrichtian age terrestrial horizon of the Lance Formation. In 1943, American paleontologist Barnum Brown referred the find to ''Edmontonia longiceps''. In 1988, Robert Thomas Bakker decided to split the genus ''Edmontonia''. The species ''Edmontonia rugosidens'' he made into a separate genus ''Chassternbergia'' and the Denver fossil was named and described as a new genu ...

Robert Bakker
Robert Thomas Bakker (born March 24, 1945) is an American paleontologist who helped reshape modern theories about dinosaurs, particularly by adding support to the theory that some dinosaurs were endothermic (warm-blooded). Along with his mentor John Ostrom, Bakker was responsible for initiating the ongoing " dinosaur renaissance" in paleontological studies, beginning with Bakker's article "Dinosaur Renaissance" in the April 1975 issue of ''Scientific American''. His specialty is the ecological context and behavior of dinosaurs. Bakker has been a major proponent of the theory that dinosaurs were warm-blooded, smart, fast, and adaptable. He published his first paper on dinosaur endothermy in 1968. His seminal work, '' The Dinosaur Heresies,'' was published in 1986. He revealed the first evidence of parental care at nesting sites for ''Allosaurus''. He also observed evidence in support of Eldredge and Gould's theory of punctuated equilibrium in dinosaur populations. Bakker curren ...

PhyloCode
The ''International Code of Phylogenetic Nomenclature'', known as the ''PhyloCode'' for short, is a formal set of rules governing phylogenetic nomenclature. Its current version is specifically designed to regulate the naming of clades, leaving the governance of species names up to the rank-based nomenclature codes ('' ICN'', ''ICNCP'', '' ICNP'', '' ICZN'', '' ICVCN''). The ''PhyloCode'' is associated with the International Society for Phylogenetic Nomenclature (ISPN). The companion volume, ''Phylonyms'', establishes 300 taxon names under ''PhyloCode'', serving as examples for those unfamiliar with the code. RegNum is an associated online database for registered clade names. The ''PhyloCode'' regulates phylogenetic nomenclature by providing rules for deciding which associations of names and definitions are considered established, which of those will be considered homonyms or synonyms, and which one of a set of synonyms or homonyms will be considered accepted (generally the one regi ...

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 ...

Sauropelta
''Sauropelta'' ( ; meaning 'lizard shield') is a genus of nodosaurid dinosaur that existed in the Early Cretaceous Period of North America. One species (''S. edwardsorum'') has been named although others may have existed. Anatomically, ''Sauropelta'' is one of the most well-understood nodosaurids, with fossilized remains recovered in the U.S. states of Wyoming, Montana, and possibly Utah. It is also the earliest known genus of nodosaurid; most of its remains are found in a section of the Cloverly Formation dated to 108.5 million years ago. It was a medium-sized nodosaurid, measuring about long. ''Sauropelta'' had a distinctively long tail which made up about half of its body length. Although its body was smaller than a modern black rhinoceros, ''Sauropelta'' was about the same mass, weighing in at about . The extra weight was largely due to its extensive covering of bony armor, including the characteristically large spines projecting from its neck. Description ''Sauropelta'' ...

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 ...

Taohelong
''Taohelong'' is a genus of nodosaurid dinosaur known from Lower Cretaceous rocks in north-central China. ''Taohelong'' is based on Gansu Dinosaur Museum (GSDM) 00021, fossils including a tail vertebra, ribs, a left ilium (the main bone of the hip), and bony armor recovered from the Hekou Group in the Lanzhou-Minhe Basin. The animal's armor includes part of a "sacral shield", a carpet of osteoderms over the hips found in some other ankylosaurians. ''Taohelong'' was named and described in 2013 by Yang Jing-Tao, You Hai-Lu, Li Da-Qing, and Kong De-Lai. The type species is ''Taohelong jinchengensis''. The generic name means "dragon (''long'') of the river (''he'') Tao". The specific name refers to the provenance at Jincheng. The describers established some diagnostic traits. The neural channel of the tail vertebra has a cross-section like an inverted trapezium. In top view the profile of the outer rim of the ilium is like a mirrored "S".
