Narindasaurus
''Narindasaurus'' (meaning "lizard of Narinda Bay") is a genus of turiasaurian sauropod dinosaur from the Middle Jurassic Isalo III Formation of Madagascar. The type species, ''N. thevenini'' was formally described by Royo-Torres ''et al.'' in 2020. The holotype, which consists of one specimen, is currently stored at the Muséum national d’Histoire naturelle and has been since 1906 or 1907. Discovery and naming The holotype was discovered in the Isalo III Formation before 1894 by Joseph Thomas Last, and were briefly noted on by Paul Lemoine in 1906.Lemoine P. 1906. Études géologiques dans le nord de Madagascar. In: Herman A, ed. Contributions à l’histoire géologique de l’Océan Indien. ''Paris: Librairie Scientifique'', 1–520. Armand Thevenin (1861-1942) was the first to diagnose ''Narindasaurus''. In 1907, he placed it within the now obsolete species "'' Bothriospondylus madagascariensis''", which is now known as ''Lapparentosaurus ''Lapparentosaurus'' is a g ...

Turiasauria
Turiasauria is an unranked clade of basal sauropod dinosaurs known from Middle Jurassic to Early Cretaceous deposits in Europe, North America, and Africa. Description Turiasauria was originally erected by Royo-Torres et al. (2006) to include ''Turiasaurus'', ''Galveosaurus'' and ''Losillasaurus'', all of which hail from the Villar del Arzobispo Formation (Tithonian-Berriasian) of Spain. Turiasuria was defined by the authors as "all Eusauropoda closer to ''Turiasaurus riodevensis'' than to ''Saltasaurus loricatus''". Cladistic analysis (Royo-Torres ''et al.'', 2006; 1927) of 309 characters and 33 taxa suggests that the turiasaurians lie outside the Neosauropoda and form a monophyletic group. The clade is diagnosed by the presence of vertical neural spines, posterior centroparapohyseal laminae on the dorsal vertebrae, the absence of pre- and postspinal laminae on the dorsal vertebrae, the absence of a scapular acromial crest, the presence of a prominent humeral deltopectoral crest, ...

Isalo III
The Isalo III Formation is a geological formation in Madagascar, off the eastern coast of Africa. It dates back to the Middle Jurassic.Weishampel et al., 2004, pp.542-543 The use of the term "Isalo III" is somewhat controversial as the two prior units Isalo I and II are Triassic cross-bedded sandstone units that form a continuous depositional sequence, while the "Isalo III" sandstones are not part of the same depositional sequence, and were deposited considerably later. and are perhaps better treated as part of several separate formations.Geiger et al., 2004 It is traditionally divided into two subunits the lower, Bajocian aged Isalo IIIa unit also known as the Beronono Formation and the upper, Bathonian aged Isalo IIIb unit also known as the Sakaraha Formation or Sakahara Formation. The Sakaraha Formation consists of sandstones, marls and carbonates and represents a coastal plain environment, and is laterally equivalent to the predominantly carbonate Bemaraha Formation, which re ...

Lapparentosaurus
''Lapparentosaurus'' is a genus of sauropod dinosaur from the Middle Jurassic. Its fossils were found in Madagascar (Isalo III Formation). The type species is ''L. madagascariensis''. Discovery and naming In 1895 Richard Lydekker named a new species of ''Bothriospondylus'', ''B. madagascariensis'' based on fossils found before 1894 by Joseph Thomas Last in the Majunga Basin in layers of the Bathonian, the Isalo III Formation. Because there was no real connection with this English form, in 1986 José Fernando Bonaparte named a separate genus. The type species, the only known, is ''Lapparentosaurus madagascariensis''. The generic name honours Albert-Félix de Lapparent. The holotype assigned by Bonaparte, MAA 91-92, consists of two neural arches. Much more abundant material has been referred, from at least three but perhaps as much as ten individuals from different growth stages. This includes vertebrae and limb elements but no skulls. The species is still lacking a good descri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Jurassic
The Middle Jurassic is the second epoch of the Jurassic Period. It lasted from about 174.1 to 163.5 million years ago. Fossils of land-dwelling animals, such as dinosaurs, from the Middle Jurassic are relatively rare, but geological formations containing land animal fossils include the Forest Marble Formation in England, the Kilmaluag Formation in Scotland,British Geological Survey. 2011Stratigraphic framework for the Middle Jurassic strata of Great Britain and the adjoining continental shelf: research report RR/11/06 British Geological Survey, Keyworth, Nottingham. the Daohugou Beds in China, the Itat Formation in Russia, and the Isalo III Formation of western Madagascar. Paleogeography During the Middle Jurassic Epoch, Pangaea began to separate into Laurasia and Gondwana, and the Atlantic Ocean formed. Eastern Laurasia was tectonically active as the Cimmerian plate continued to collide with Laurasia's southern coast, completely closing the Paleo-Tethys Ocean. A subduction zone ...

Joseph Thomas Last
Joseph Thomas Last (1849, Tuddenham- 1933, Shortlands) was an English missionary, explorer and naturalist. In 1872 Last was ordained at the Church Missionary College. From 1874 to 1876 he was in East Africa at the mission at Kisulutini. He briefly returned to Britain and then in 1877 he was appointed to the Usagara Mission at Mpwapwa. In 1880 he founded a new station at Mamboya in the Nguru mountains. After seven years in East Africa he returned to Britain in December 1884. Later he was associated with Royal Geographical Society and the Imperial British East Africa Company. He visited Portuguese East Africa in 1885, explored the Namuli Mountains and discovered the caves at Mangapwani in Zanzibar. Last made important collections of African Lepidoptera and Mollusca Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks ().

Fossils Of Madagascar
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absol ...

Callovian Life
In the geologic timescale, the Callovian is an age and stage in the Middle Jurassic, lasting between 166.1 ± 4.0 Ma (million years ago) and 163.5 ± 4.0 Ma. It is the last stage of the Middle Jurassic, following the Bathonian and preceding the Oxfordian. Stratigraphic definitions The Callovian Stage was first described by French palaeontologist Alcide d'Orbigny in 1852. Its name derives from the latinized name for Kellaways Bridge, a small hamlet 3 km north-east of Chippenham, Wiltshire, England. The base of the Callovian is defined as the place in the stratigraphic column where the ammonite genus ''Kepplerites'' first appears, which is the base of the biozone of '' Macrocephalites herveyi''. A global reference profile (a GSSP) for the base had in 2009 not yet been assigned. The top of the Callovian (the base of the Oxfordian) is at the first appearance of ammonite species '' Brightia thuouxensis''. Subdivision The Callovian is often subdivided into three substages ...

Bathonian Life
In the geologic timescale the Bathonian is an age and stage of the Middle Jurassic. It lasted from approximately 168.3 Ma to around 166.1 Ma (million years ago). The Bathonian Age succeeds the Bajocian Age and precedes the Callovian Age. Stratigraphic definitions The Bathonian Stage takes its name from Bath, a spa town in England built on Jurassic limestone (the Latinized form of the town name is ''Bathonium''). The name was introduced in scientific literature by Belgian geologist d'Omalius d'Halloy in 1843. The original type locality was located near Bath. The French palaeontologist Alcide d'Orbigny was in 1852 the first to define the exact length of the stage. The base of the Bathonian is at the first appearance of ammonite species '' Parkinsonia (Gonolkites) convergens'' in the stratigraphic column. The global reference profile for the base of the Bathonian (a GSSP) was ratified as Ravin du Bès, Bas-Auran area, Alpes de Haute Provence, France in 2009. The top of the Bath ...

Bothriospondylus
''Bothriospondylus'' ("excavated vertebra") is a dubious genus of neosauropod sauropod dinosaur. It lived during the Late Jurassic. Discovery and naming The type species, ''Bothriospondylus suffossus'', was described by Richard Owen in 1875. The specific epithet ''suffossus'' means "undermined" in Latin, a reference to the fact that pleurocoels had hollowed out the sides of the vertebra. It is often incorrectly spelled as "suffosus". Owen based the species on holotype NHMUK R.44592-5, a set of four dorsal vertebrae found in Wiltshire in stratum from the Kimmeridgian, the Kimmeridge Clay. Also three unfused sacral vertebrae were referred. At the same time Owen named three other species of ''Bothriospondylus''. ''B. robustus'' was based on NHMUK R.22428, a dorsal from the same location. ''B. elongatus'' was based on a vertebra from Sussex, NHMUK R.2239, an original syntype of ''Ornithopsis hulkei''. Finally, '' Bothriospondylus magnus'' was a new name for another syntype of ''Ornit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
