Supersaurus Lourinhanensis
''Dinheirosaurus'' is a genus of diplodocid sauropod dinosaur that is known from fossils uncovered in modern-day Portugal. It may represent a species of ''Supersaurus''. The only species is ''Dinheirosaurus lourinhanensis'', first described by José Bonaparte and Octávio Mateus in 1999 for vertebrae and some other material from the Lourinhã Formation. Although the precise age of the formation is not known, it can be dated around the early Tithonian of the Late Jurassic. The known material includes two cervical vertebrae, nine dorsal vertebrae, a few ribs, a fragment of a pubis, and many gastroliths. Of the material, only the vertebrae are diagnostic, with the ribs and pubis being too fragmentary or general to distinguish ''Dinheirosaurus''. This material was first described as in the genus ''Lourinhasaurus'', but differences were noticed and in 1999 Bonaparte and Mateus redescribed the material under the new binomial ''Dinheirosaurus lourinhanensis''.

Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of din ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lourinhasaurus
''Lourinhasaurus'' (meaning "Lourinhã lizard") was an herbivorous sauropod dinosaur genus dating from Late Jurassic strata of Estremadura, Portugal. Discovery The first find in 1949 by Harold Weston Robbins, a partial fossil skeleton found near Alenquer, was in 1957 named ''Apatosaurus alenquerensis'' by Albert-Félix de Lapparent and Georges Zbyszewski. The specific name ''alenquerensis'' refers to the locality of Alenquer. The species has subsequently been referred to other genera. In 1970 Rodney Steel renamed it ''Atlantosaurus alenquerensis'', in 1978 George Olshevsky coined a ''Brontosaurus alenquerensis''. John Stanton McIntosh in 1990 proposed that it was a species of ''Camarasaurus'': ''Camarasaurus alenquerensis''. However, the find of another partial skeleton, ML 414, including a tooth and a hundred gastroliths, in co-eval strata near the town of Lourinhã in 1983, induced Pedro Dantas e.a. in 1998 to see the taxon as a distinct form from ''Apatosaurus'' and ''C ...

Pelvis
The pelvis (plural pelves or pelvises) is the lower part of the trunk, between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis, or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs (sex organs) and the rectum, while the p ...

Lourinhã
Lourinhã () is a municipality in the District of Lisbon, in the Oeste Subregion of Portugal. The population in 2011 was 25,735, in an area of 147.17 km². The seat of the municipality is the town of Lourinhã, with a population of 8,800 inhabitants. The present Mayor is João Duarte, elected by the Socialist Party. History The name Lourinhã possibly originated in the period of Roman domination, when a villa was located in the area. The origin of the medieval village is linked to ''Jordan'', a French knight who took part in the successful Siege of Lisbon in 1147. King Afonso Henriques granted Jordan the region of Lourinhã as fief and allowed him to grant a foral (letter of feudal rights) to its settlers in 1160. The name Lourinhã may be related to the origin of its feudal lord, since Jordan was from the Loire region in France. The rights of Lourinhã were confirmed by letters of King Sancho I in 1218 and again by Afonso III in 1258. The parish of Lourinhã became one o ...

Porto Dinheiro
Porto Dinheiro (or Praia de Porto Dinheiro) is a locality in the civil parish (''freguesia'') of Ribamar, municipality of Lourinhã, in Portugal. It is known as a rich fossil locality, from where were found many Late Jurassic dinosaurs and mammals. A few even received the locality name, like the ''Dinheirosaurus lourinhanensis'' and Jurassic mammals like ''Portopinheirodon asymmetricus'' and the multituberculates family Pinheirodontidae. The second one is the based for a new family of mammals, the Pinheirodontidae. An diverse ichnofaunaMateus, O., & Milàn, J. (2009).

Morrison Formation
The Morrison Formation is a distinctive sequence of Upper Jurassic sedimentary rock found in the western United States which has been the most fertile source of dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone, and limestone and is light gray, greenish gray, or red. Most of the fossils occur in the green siltstone beds and lower sandstones, relics of the rivers and floodplains of the Jurassic period. It is centered in Wyoming and Colorado, with outcrops in Montana, North Dakota, South Dakota, Nebraska, Kansas, the panhandles of Oklahoma and Texas, New Mexico, Arizona, Utah, and Idaho. Equivalent rocks under different names are found in Canada. It covers an area of 1.5 million square kilometers (600,000 square miles), although only a tiny fraction is exposed and accessible to geologists and paleontologists. Over 75% is still buried under the prairie to the east, and much of its western paleogeographic extent was eroded during exhumation ...

Museu Da Lourinhã
Museu da Lourinhã is a museum in the town of Lourinhã, west Portugal. It was founded in 1984 by GEAL - Grupo de Etnologia e Arqueologia da Lourinhã (Lourinhã's Group of Ethnology and Archeology). The president of the Direction Board is Lubélia Gonçalves. The museum has very complete exhibits of archaeology and ethnology, but the main focus of the museum is the palaeontology hall, which presents casts of famous dinosaurs, as well as fossils recovered from the Late Jurassic Lourinhã Formation. Among these is the famous theropod nest found at the beach of Paimogo, which contains eggs with embryos inside, probably belonging to ''Lourinhanosaurus''. Many of the fossils that belong to the Museu da Lourinhã are on display at Dinoparque Lourinhã, such as the sauropod '' Zby atlanticus'', ''Lourinhanosaurus antunesi'', and '' Torvosaurus gurneyi''. The paleontological research has been conducted by the paleontologists Miguel Telles Antunes, Octávio Mateus Octávio Mateus (born 1 ...

Tornieria
''Tornieria'' ("for Tornier") is a genus of diplodocid sauropod dinosaur from the Late Jurassic in Lindi Region of Tanzania. It has a convoluted taxonomic history. Discovery and naming In 1907, German paleontologist Eberhard Fraas who was working the Tendaguru Beds in German East Africa (presently Tanzania), discovered two sauropod specimens at a single site ("Quarry A"). The two individuals, designated "Skeleton A" and "Skeleton B", each represented a different sauropod species. In 1908 he named these respectively ''Gigantosaurus africanus'' ("African giant lizard") and ''G. robustus'' ("Robust giant lizard"). A third, unrelated African species, "Gigantosaurus" ''dixeyi'', was named by Haughton in 1928, and has since been reassigned to ''Malawisaurus''. However, the name ''Gigantosaurus'' had already been used for the European sauropod ''Gigantosaurus megalonyx'' Seeley, 1869. Fraas, not intending to place his species in the same genus as this English form, had believed that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barosaurus
''Barosaurus'' ( ) was a giant, long-tailed, long-necked, plant-eating sauropod dinosaur closely related to the more familiar '' Diplodocus''. Remains have been found in the Morrison Formation from the Upper Jurassic Period of Utah and South Dakota. It is present in stratigraphic zones 2–5.Foster, J. (2007). "Appendix." ''Jurassic West: The Dinosaurs of the Morrison Formation and Their World''. Indiana University Press. pp. 327-329. The composite term ''Barosaurus'' comes from the Greek words ''barys'' (βαρυς) meaning "heavy" and ''sauros'' (σαυρος) meaning "lizard"; thus "heavy lizard". Description ''Barosaurus'' was an enormous animal, with some adults measuring about in length and weighing about 12–20 metric tons (13–22 short tons).Paul, G.S., 2016, ''The Princeton Field Guide to Dinosaurs 2nd edition'', Princeton University Press p. 213 There are some indications of even larger individuals, such as the enormous cervical vertebra from the ...

Diplodocus
''Diplodocus'' (, , or ) was a genus of diplodocid sauropod dinosaurs, whose fossils were first discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a neo-Latin term derived from Greek διπλός (''diplos'') "double" and δοκός (''dokos'') "beam", in reference to the double-beamed chevron bones located in the underside of the tail, which were then considered unique. The genus of dinosaurs lived in what is now mid-western North America, at the end of the Jurassic period. It is one of the more common dinosaur fossils found in the middle to upper Morrison Formation, between about 154 and 152 million years ago, during the late Kimmeridgian Age. The Morrison Formation records an environment and time dominated by gigantic sauropod dinosaurs, such as ''Apatosaurus'', '' Barosaurus'', ''Brachiosaurus'', '' Brontosaurus'', and '' Camarasaurus''. Its great size may have been a deterrent to the predators ''Allosaurus'' and '' Ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apatosaurus
''Apatosaurus'' (; meaning "deceptive lizard") is a genus of herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period. Othniel Charles Marsh described and named the first-known species, ''A. ajax'', in 1877, and a second species, ''A. louisae'', was discovered and named by William H. Holland in 1916. ''Apatosaurus'' lived about 152 to 151 million years ago (mya), during the late Kimmeridgian to early Tithonian age, and are now known from fossils in the Morrison Formation of modern-day Colorado, Oklahoma, New Mexico, Wyoming, and Utah in the United States. ''Apatosaurus'' had an average length of , and an average mass of . A few specimens indicate a maximum length of 11–30% greater than average and a mass of approximately . The cervical vertebrae of ''Apatosaurus'' are less elongated and more heavily constructed than those of '' Diplodocus'', a diplodocid like ''Apatosaurus'', and the bones of the leg are much stockier despite being ...

Ornithopod
Ornithopoda () is a clade of ornithischian dinosaurs, called ornithopods (), that started out as small, bipedal running grazers and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, dominating the North American land. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex of diversity and ecological dominance in the hadrosaurids (colloquially known as 'duck-bills'), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non- avian dinosaurs. Members are known from all seven continents, though they are generally rare in the Southern Hemisphere. History of research In 1870, Thomas Henry Huxley listed Iguanodontidae (coined by Cope a year earlier) as one of his three families of dinosa ...
