Museum of the Rockies is a museum in Bozeman, Montana.
 Originally affiliated with Montana State University in Bozeman, and now, also, the Smithsonian Institution, the museum is known for its paleontological collections, although these are not its sole focus.
 The Museum of the Rockies houses the largest collection of dinosaur remains in the United States, possessing the largest "Tyrannosaurus" skull ever discovered, as well as the thigh bone of a "Tyrannosaurus rex" that contains soft-tissue remains.
 The museum is part of the Montana Dinosaur Trail and is Montana's official repository for paleontological specimens.
The sea mink ("Neovison macrodon") is a recently extinct species of carnivore from the eastern coast of North America in the family Mustelidae, the largest family in the order Carnivora.
 It was most closely related to the American mink ("Neovison vison"), with debate about whether or not the sea mink should be considered a subspecies of the American mink (making it "Neovison vison macrodon") or a species of its own.
 The main justification for a separate-species designation is the size difference between the two minks, but other distinctions have been made, such as its redder fur.
 The only known remains are fragments unearthed in Native American shell middens. Its actual size is speculative, based largely on tooth remains.
Cro-Magnon ( or ; ] ) is a common name that has been used to describe the first early modern humans (early "Homo sapiens sapiens") that lived in the European Upper Paleolithic.
 Current scientific literature prefers the term European early modern humans (EEMH), to the term Cro-Magnon, which has no formal taxonomic status, as it refers neither to a species or subspecies nor to an archaeological phase or culture.
 The earliest known remains of Cro-Magnon-like humans are radiocarbon dated to 43,000–45,000 years before present that have been discovered in Italy and Britain, with the remains found of those that reached the European Russian Arctic 40,000 years ago.
Neuquensuchus (meaning "Neuquén crocodile", referring to the city) is an extinct genus of notosuchian crocodyliform from the Santonian-age Upper Cretaceous Bajo de la Carpa Formation of Neuquén Province, Argentina.
 The known remains were discovered on the campus of Universidad Nacional del Comahue in the city of Neuquén.
 "Neuquensuchus" was named by Lucas E. Fiorelli and Jorge O. Calvo in a publication dated to 2007, but which became available in 2008.
 The type species is "N. universitas", in recognition of its discovery locality.
 Unlike the great majority of crocodyliforms, its shin was longer than its thigh, suggesting it had some running ability.
Piksi is a potential theropod genus containing the single species Piksi barbarulna (meaning "strange elbowed big bird", from Blackfoot "piksi", "big bird" or, specifically, "chicken" and Latin "barbarus" "strange, outlandish" + "ulna", elbow).
 It lived roughly 75 million years ago in what is now Montana, United States.
 Known from parts of a right wing – the humerus, ulna and radius bones – the only specimens found so far are housed in the Museum of the Rockies (collection number MOR 1113).
 The genus Piksi is monotypic at present.
Vancleavea is a genus of extinct, armoured, non-archosaurian archosauriform with relatively small limbs from the Late Triassic of western North America.
 The type and only species is "V. campi", named by Robert Long & Phillip A Murry, 1995.
 A nearly complete and articulated skeleton was discovered at the Coelophysis Quarry in north-central New Mexico (Ghost Ranch), USA, and was prepared at the Ruth Hall Museum of Paleontology in Abiquiú, New Mexico before being formally described in the "Zoological Journal of the Linnean Society" in 2009.
 "Vancleavea" was first discovered in 1962 from the Petrified Forest Member of the Petrified Forest National Park and initially described by Long and Murry in 1995.
 The genus is named after Phillip Van Cleave, who discovered the first known remains of the genus.
 "Vancleavea" is a fairly common occurrence in most levels of the Chinle Formation, however, due to the poorly preserved remains, it is difficult to compare specimens across stratigraphic levels.
The Bishop's Tower (German: "Bischofsturm" ), or Bishop's Castle ("Bischofsburg "), is an archaeological site in the historic city center of Hamburg, Germany, containing the oldest known remains of a stone building in the city.
 The site includes the foundations of a circular tower and a well, originally believed to represent the 11th-century stone residence of Archbishop Adalbrand of Bremen.
 Later finds, however, disproved this theory and it is now considered to be part of a 12th-century defensive structure.
Tarjadia is an extinct genus of Triassic archosauriform.
 It is known from a single species, "T. ruthae", first described in 1998 from the Middle Triassic Los Chañares Formation in Argentina.
 Partial remains have been found from deposits that are Anisian-Ladinian in age.
 The genus is known mostly from osteoderms, as well as several vertebrae and fragments of the skull.
 "Tarjadia" predates the Late Triassic aetosaurs and phytosaurs, two early groups of crurotarsans with heavy plating, making it one of the first heavily armored archosaurs.
 However, its classification within Archosauria is uncertain, as the known remains are fragmentary.
Stromerosuchus is a dubious genus of Late Cretaceous crocodyliform.
 Fragmentary remains have been found from the Cenomanian-age Bahariya Formation of Egypt.
 The genus was named in 1936 by Oskar Kuhn.
 It is named in honor of Ernst Stromer, the German paleontologist who found the fossils in the Bahariya Oasis in 1911 and described them in 1922.
 After their discovery, the fossils, along with many others found from Bahariya, were in the possession of the Egyptian Geological Survey.
 In 1922, the fossils were sent back to Stromer (who was in Germany at the time), but they were badly crushed in shipment from Egypt.
 Because the known remains are so poor, the genus is now regarded as a "nomen dubium".
 Some material has been referred to the genera "Aegyptosuchus" and "Stomatosuchus", both named by Stromer from the Bahariya material.
Defensive walls are a feature of ancient Roman architecture.
 The Romans generally fortified cities, rather than fortresses, but there are some fortified camps, such as the Saxon Shore forts like Porchester Castle in England.
 City walls were already significant in Etruscan architecture, and in the struggle for control of Italy under the early Republic many more were built, using different techniques.
 These included tightly-fitting massive irregular polygonal blocks, shaped to fit exactly in a way reminiscent of later Inca work.
 The Romans called a simple rampart wall an agger; at this date great height was not necessary.
 The Servian Wall around Rome was an ambitious project of the early 4th century BC.
 The wall was up to 10 metres (32.8 ft) in height in places, 3.6 metres (12 ft) wide at its base, 11 km (7 mi) long, and is believed to have had 16 main gates, though many of these are mentioned only from writings, with no other known remains.
 Some of it had a "fossa" or ditch in front, and an agger behind, and it was enough to deter Hannibal.
 Later the Aurelian Wall replaced it, enclosing an expanded city, and using more sophisticated designs, with small forts at intervals.
