PanoplosaurusPanoplosaurus 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".
Timeline of ankylosaur researchThis timeline of ankylosaur research is a chronological listing of events in the history of paleontology focused on the ankylosaurs, quadrupedal herbivorous dinosaurs who were protected by a covering bony plates and spikes and sometimes by a clubbed tail. Although formally trained scientists did not begin documenting ankylosaur fossils until the early 19th century, Native Americans had a long history of contact with these remains, which were generally interpreted through a mythological lens.
PeloroplitesPeloroplites (meaning “monstrous heavy one”) is a monospecific genus of 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 postcranial skeleton. It was named in 2008 by Kenneth Carpenter and colleagues.
EuropeltaEuropelta (meaning “Europe’s shield”) is a monospecific genus of nodosaurid dinosaur from Spain that lived during the Early Cretaceous (early Albian stage, ~113.0 Ma) in what is now the lower Escucha Formation of the Teruel Province. The type and only species, Europelta carbonensis, is known from two associated partial skeletons, and represents the most complete ankylosaur known from Europe. Europelta was named in 2013 by James I. Kirkland and colleagues. Europelta has an estimated length of 5 metres (16 feet) and weight of 1.
AcantholipanAcantholipan is a genus of herbivorous nodosaurid dinosaur from Mexico from the early Santonian age of the Late Cretaceous. It includes one species, Acantholipan gonzalezi. 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.
