Context: The Triassic is a geologic period and system which spans 50.9 million years from the end of the Permian Period million years ago (Mya), to the beginning of the Jurassic Period Mya. The Triassic is the first period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic was named in 1834 by Friedrich von Alberti, after the three distinct rock layers ("tri" meaning "three") that are found throughout Germany and northwestern Europered beds, capped by marine limestone, followed by a series of terrestrial mud- and sandstonescalled the "Trias"., Indian Statistical Institute (ISI) is an academic institute of national importance as recognised by a 1959 act of the Indian parliament. It grew out of the Statistical Laboratory set up by Prasanta Chandra Mahalanobis in Presidency College, Kolkata. Established in 1931, this public university of India is one of the oldest and most prestigious institutions focused on statistics, and its early reputation led it to being adopted as a model for the first US institute of Statistics set up at the Research Triangle, North Carolina by Gertrude Mary Cox., Thailand (or  ), officially the Kingdom of Thailand, formerly known as Siam, is a country at the centre of the Indochinese peninsula in Southeast Asia. With a total area of approximately , Thailand is the world's 51st-largest country. It is the 20th-most-populous country in the world, with around 66 million people. The capital and largest city is Bangkok., Isisaurus ( named after the Indian Statistical Institute ) is a genus of dinosaur from the Late Cretaceous Period . Isisaurus was a sauropod ( specifically a titanosaur ) , which lived in what is now India . The type specimen of Isisaurus colberti , ISI R 335/1 - 65 , was originally described and named as Titanosaurus colberti by Sohan Lal Jain and Saswati Bandyopadhyay in 1997 , the specific name honouring Edwin Harris Colbert , but was placed in its own genus , by Wilson and Upchurch , in 2003 . It had a `` bizarre '' appearance with a short , vertically directed neck and long forelimbs , making it considerably different from other sauropods . The humerus is 148 centimetres long . Based on this specimen , Isisaurus would have grown to about 18 meters ( 60 feet ) in length and weighed about 14,000 kg ( 15 tons ) . Isisaurus is known from much better remains than most titanosaurs . Most of its postcranial skeleton is known . The skeletal material Jain and Bandyopadhyay found between 1984 and 1986 was `` in associated and mostly articulated condition ; '' it included cervical , dorsal , sacral and caudal vertebrae , ribs , pelvis , scapula , coracoid , left forelimb and other bones , though skull , hindlimb and foot bones were missing . The site locality is Dongargaon Hill , which is in a Maastrichtian crevasse splay claystone in the Lameta Formation of India . Dongargaon Hill ( 20.212318N,79.090709E ) near Warora , in Chandrapur District , Maharashtra . Fungus in coprolites believed to have been voided by Isisaurus indicate that it ate leaves from several species of tree , since these fungi are known to be pathogens which infect tree leaves ., The Cretaceous is a geologic period and system that spans 79 million years from the end of the Jurassic Period million years ago (Mya) to the beginning of the Paleogene Period Mya. It is the last period of the Mesozoic Era. The Cretaceous Period is usually abbreviated K, for its German translation "Kreide" (chalk)., Kolkata (, also known as Calcutta , the official name until 2001) is the capital of the Indian state of West Bengal. Located on the east bank of the Hooghly River, it is the principal commercial, cultural, and educational centre of East India, while the Port of Kolkata is India's oldest operating port and its sole major riverine port. In 2011, the city had population of 4.5 million, while the population of the city and its suburbs was 14.1 million, making it the third-most populous metropolitan area in India. In 2008 its gross domestic product (adjusted for purchasing power parity) was estimated to be 104 billion, which was the third highest among Indian cities, behind Mumbai and Delhi., Titanosaurus (meaning 'titanic lizard' - named after the mythological 'Titans', deities of Ancient Greece) is a dubious genus of sauropod dinosaurs, first described by Lydekker in 1877. It is known from the Maastrichtian (Upper Cretaceous) Lameta Formation of India., The Paleogene (or ; also spelled Palaeogene or Palæogene; informally Lower Tertiary) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The Paleogene is most notable for being the time during which mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of the CretaceousPaleogene extinction event that ended the preceding Cretaceous Period. , Dinosaurs are a diverse group of animals of the clade Dinosauria that first appeared during the Triassic. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago. They became the dominant terrestrial vertebrates after the TriassicJurassic extinction event 201 million years ago. Their dominance continued through the Jurassic and Cretaceous periods and ended when the CretaceousPaleogene extinction event led to the extinction of most dinosaur groups 66 million years ago., Ancient Greece was a civilization belonging to a period of Greek history from the Greek Dark Ages of the 12th-9th centuries BC to the end of antiquity (AD). Immediately following this period was the beginning of the Early Middle Ages and the Byzantine era. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the period of Archaic Greece and colonization of the Mediterranean Basin. This was followed by the period of Classical Greece, an era that began with the Greco-Persian Wars, lasting from the 5th to 4th centuries BC. Due to the conquests by Alexander the Great of Macedonia, Hellenistic civilization flourished from Central Asia to the western end of the Mediterranean Sea. The Hellenistic period came to an end with the conquests and annexations of the eastern Mediterranean world by the Roman Republic, which established the Roman province of Macedonia in Roman Greece, and later the province of Achaea during the Roman Empire., Bengal (bgl; Bengali: ,  and ) is a region in Asia which is located in the eastern part of the Indian subcontinent at the apex of the Bay of Bengal.

When the extinction event at the end of the Cretaceous period occurred, they were the last surviving group of long-necked dinosaurs. The group includes some of the heaviest creatures ever to walk the earth, such as "Argentinosaurus" and "Puertasaurus", which are estimated to have weighed up to . The group's name refers to the much earlier discovery "Titanosaurus", a now dubious genus named for the mythological Titans of Ancient Greece. Together with the brachiosaurids and relatives, titanosaurs make up the larger clade Titanosauriformes., Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people., Delhi (Dilli) , officially the National Capital Territory of Delhi, is a city and a union territory of India. It is bordered by Haryana on three sides and by Uttar Pradesh to the east. It is the most expansive city in Indiaabout . It has a population of about 25 million, making it the second most populous city after Mumbai and most populous urban agglomeration in India and 3 largest urban area in the world. Urban expansion in Delhi has caused it to grow beyond the NCT to incorporate towns in neighbouring states. At its largest extent, there is a population of about 25 million residents . According to data released by Oxford Economics, Delhi NCR urban agglomeration has replaced Mumbai Metropolitan Region urban agglomeration as the economic capital of India. However the comparison of the figures specific to the Metropolis of Delhi and Metropolis of Mumbai was not provided by this institution. These figures however did not match with those revealed by the reserve bank of India, The economic survey of India, The economic survey of Delhi and Maharashtra., The TriassicJurassic extinction event marks the boundary between the Triassic and Jurassic periods, , and is one of the major extinction events of the Phanerozoic eon, profoundly affecting life on land and in the oceans. In the seas, a whole class (conodonts) and 34% of marine genera disappeared. On land, all pseudosuchians (non-ornithodiran archosaurs) other than crocodylomorphs (Sphenosuchia and Crocodyliformes), some remaining therapsids, and many of the large amphibians became extinct., Chennai ; formerly known as Madras or ) is the capital of the Indian state of Tamil Nadu. Located on the Coromandel Coast off the Bay of Bengal, it is one of the biggest cultural, economic and educational centres in South India. According to the 2011 Indian census, it is the sixth-largest city and fourth-most populous urban agglomeration in India.

Chennai is among the most visited Indian cities by foreign tourists. It was ranked 43rd most visited city in the world for year 2015. The Quality of Living Survey rated Chennai as the safest city in India. Chennai attracts 45 percent of health tourists visiting India, and 30 to 40 percent of domestic health tourists. As such, it is termed "India's health capital". As a growing metropolitan city in a developing country, Chennai confronts substantial pollution and other logistical and socio-economic problems., Saltasaurus (which means "lizard from Salta") is a genus of titanosaurid sauropod dinosaur of the Late Cretaceous Period of Argentina. Small among sauropods, though still heavy by the standards of modern creatures, "Saltasaurus" was characterized by a short neck and stubby limbs. It was the first genus of sauropod known to possess armour of bony plates embedded in its skin. Such small bony plates, called osteoderms, have since been found on other titanosaurids. , Argentinosaurus (meaning "Argentine lizard") is a genus of titanosaur sauropod dinosaur first discovered by Guillermo Heredia in Argentina. The generic name refers to the country in which it was discovered. The dinosaur lived on the then-island continent of South America somewhere between 94 and 97 million years ago, during the Late Cretaceous Period. It is among the largest known dinosaurs., The Jurassic (from Jura Mountains) is a geologic period and system that spans 56.3 million years from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period Mya. The Jurassic constitutes the middle period of the Mesozoic Era, also known as the Age of Reptiles. The start of the period is marked by the major TriassicJurassic extinction event. Two other extinction events occurred during the period: the Pliensbachian/Toarcian event in the Early Jurassic, and the Tithonian event at the end; however, neither event ranks among the "Big Five" mass extinctions., Mumbai (also known as Bombay, the official name until 1995) is the capital city of the Indian state of Maharashtra.

The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower., Puertasaurus is a genus of titanosaurid sauropod that appeared during the Late Cretaceous. Its bones were recovered from the Pari Aike Formation, which is dated to be middle Cenomanian in age. It lived in what is now Patagonia. The type species, "Puertasaurus reuili", is named in honor of Pablo Puerta and Santiago Reuil, who discovered the specimen in January 2001.
