Dinheirosaurus
''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''. Another specimen, ML 418, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lourinhã Formation
The Lourinhã Formation () is a fossil rich geological formation in western Portugal, named for the municipality of Lourinhã. The formation is mostly Late Jurassic in age (Kimmeridgian/Tithonian), with the top of the formation extending into the earliest Cretaceous (Berriasian). It is notable for containing a fauna especially similar to that of the Morrison Formation in the United States and a lesser extent to the Tendaguru Formation in Tanzania. There are also similarities to the nearby Villar del Arzobispo Formation. The stratigraphy of the formation and the basin in general is complex and controversial, with the constituent member beds belonging to the formation varying between different authors. Besides the fossil bones, Lourinhã Formation is well known for the fossil tracks and fossilized dinosaur eggs. The Lourinhã Formation includes several lithostratigraphic units, such as Praia da Amoreira-Porto Novo Members and Praia Azul Member and the Assenta Member. Lithology and ...

Supersaurus
''Supersaurus'' (meaning "super lizard") is a genus of diplodocid Sauropoda, sauropod dinosaur that lived in North America during the Late Jurassic period. The type species, ''S. vivianae'', was first discovered by Vivian Jones of Delta, Colorado, in the middle Morrison Formation of Colorado in 1972. The fossil remains came from the Brushy Basin Member of the formation, dating between 153 to 145 million years ago. It was a very large sauropod, reaching in length and approximately in body mass. A potential second species, ''S. lourinhanensis'', (''Dinheirosaurus'') is known from Portugal and has been dated to a similar time. Discovery ''Supersaurus'' is present in stratigraphic zone 5 of the Morrison, dating from the Tithonian. The original fossil remains of ''Supersaurus'' were discovered in the Dry Mesa Quarry in 1972. This find yielded only a few bones: mainly the shoulder girdle, an ischium and tail vertebrae. Paleontologist James A. Jensen described ''Supersaurus''; he de ...

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 longer, imp ...

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 ''Cerato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diplodocid
Diplodocids, or members of the family Diplodocidae ("double beams"), are a group of sauropod dinosaurs. The family includes some of the longest creatures ever to walk the Earth, including ''Diplodocus'' and ''Supersaurus'', some of which may have reached lengths of up to . Description Diplodocids were generally large animals, even by sauropod standards. Thanks to their long necks and tails, diplodocids were among the longest sauropods, with some species such as ''Supersaurus vivianae'' and ''Diplodocus hallorum'' estimated to have reached lengths of or more. The heaviest diplodocids, such as ''Supersaurus'' and ''Apatosaurus'', may have weighed close to 40 tonnes. However, not all diplodocids were so large; the South American species ''Leinkupal laticauda'' was one of the smallest diplodocids, with an estimated length of only . Their heads, like those of other sauropods, were tiny with the nasal openings on the top of the head (though in life the nostrils themselves would have ...

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] |
Lourinhasaurus
''Lourinhasaurus'' (meaning "Lourinhã lizard") was an herbivorous sauropod dinosaur genus dating from Late Jurassic strata of Estremadura Province (historical), Estremadura, Portugal. Discovery The first find in 1949 by Harold Weston Robbins, a partial fossil skeleton found near Alenquer, Portugal, Alenquer, was in 1957 named ''Apatosaurus alenquerensis'' by Albert-Félix de Lapparent and Georges Zbyszewski. The specific name (zoology), specific name ''alenquerensis'' refers to the locality of Alenquer Municipality, Portugal, 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 S. McIntosh, 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 ...

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.

Thyreophora
Thyreophora ("shield bearers", often known simply as "armored dinosaurs") is a group of armored ornithischian dinosaurs that lived from the Early Jurassic until the end of the Cretaceous. Thyreophorans are characterized by the presence of body armor lined up in longitudinal rows along the body. Primitive forms had simple, low, keeled scutes or osteoderms, whereas more derived forms developed more elaborate structures including spikes and plates. Most thyreophorans were herbivorous and had relatively small brains for their body size. Thyreophora includes various subgroups, including the suborders Ankylosauria and Stegosauria. In both the suborders, the forelimbs were much shorter than the hindlimbs, particularly in stegosaurs. The clade has been defined as the group consisting of all species more closely related to ''Ankylosaurus'' than to ''Triceratops''. Thyreophora is the sister group of Cerapoda within Genasauria.

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''.
