Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, 231.4 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the start of the Jurassic (about 200 million years ago) until the end of the Cretaceous (66 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the end of the Mesozoic Era. Until the late 20th century, all groups were believed to be extinct; however, the fossil record indicates that birds are modern feathered dinosaurs, having evolved from theropod ancestors during the Jurassic Period. As such, birds were the only dinosaurs to survive the mass extinction event.
A dinosaur is a member of a largely extinct group of vertebrates which is ancestral to birds.

Dinosaurs is an American family sitcom that was originally broadcast on ABC from April 26, 1991 to July 20, 1994. The show, about a family of anthropomorphic dinosaurs (portrayed by puppets), was produced by Michael Jacobs Productions and Jim Henson Productions in association with Walt Disney Television and distributed by Buena Vista International, Inc.. The characters were designed by Henson team member Kirk Thatcher.
Dinosaurs initially featured a laugh track: it was eventually dropped as the show grew in popularity. The show utilized voice actors for the characters, which are performed by different actors and puppeteers.
News stories written at the time of the show's premiere highlighted Dinosaurs' connection to Jim Henson, an American puppeteer who died the year before. "Jim Henson dreamed up the show's basic concept about three years ago," said a New York Times article in April 1991. "'He wanted it to be a sitcom with a pretty standard structure, with the biggest differences being that it's a family of dinosaurs and their society has this strange toxic life style,' said [his son] Brian Henson. But until The Simpsons took off, said Alex Rockwell, a vice president of the Henson organization, 'people thought it was a crazy idea.'"
A web portal is most often one specially designed web site that brings information together from diverse sources in a uniform way. Usually, each information source gets its dedicated area on the page for displaying information (a portlet); often, the user can configure which ones to display. Variants of portals include mashups and intranet "dashboards" for executives and managers. The extent to which content is displayed in a "uniform way" may depend on the intended user and the intended purpose, as well as the diversity of the content. Very often design emphasis is on a certain "metaphor" for configuring and customizing the presentation of the content and the chosen implementation framework and/or code libraries. In addition, the role of the user in an organization may determine which content can be added to the portal or deleted from the portal configuration.
A portal may use a search engine API to permit users to search intranet content as opposed to extranet content by restricting which domains may be searched. Apart from this common search engines feature, web portals may offer other services such as e-mail, news, stock quotes, information from databases and even entertainment content. Portals provide a way for enterprises and organizations to provide a consistent look and feel with access control and procedures for multiple applications and databases, which otherwise would have been different web entities at various URLs. The features available may be restricted by whether access is by an authorized and authenticated user (employee,member) or an anonymous site visitor.
Portal is an Australian extreme metal band known for its unorthodox fusion of death metal with black metal. The band's hybrid musical style is characterised by heavily distorted guitar riffs, down-tuned rhythms, and vocals ranging from "menacing, echoing" sound effects to guttural grunts. Writing for Popmatters, Adrien Begrand noted that "death metal always pretends to be scary, but [...] it's all rather harmless. That said, however, I make no mistake in saying that the death metal peddled by Australia’s Portal is truly friggin' terrifying". Lead guitarist Horror Illogium has described Portal's intent as "to capture a cinematic horror scope".
Portal's main musical influences were Morbid Angel, Beherit, and Immolation. Describing the band's style, Decibel magazine said: "If Morbid Angel and Gorguts had birthed a German Expressionist child, that unholy creature would be Portal." The band has been praised for its "hellish atmosphere" and "distant, obscure" interpretation of extreme metal. Denise Falzon, writing for Exclaim!, described Portal's 2004 EP, The Sweyy, as "extremely raw [...] with heavily distorted guitar riffs that aid in the album's overall chaotic and apocalyptic atmosphere". The band's style has also been described as oriented around "constant dissonance", "sporadic compositions", and "abstract themes". However, lead guitarist Horror Illogium has disputed the view that the band's songwriting lacks structure: "We are indeed making songs, although our structures are unusual. They are constructed with a great deal of artistic, obsessive scrutiny [...] An insane asylum is a structure; our songs can be viewed as structures housing insane elements".
A portal is an opening in a wall of a building, gate or fortification, especially a grand entrance to an important structure.doors, metal gates or portcullis in the opening can be used to control entry or exit. The surface surrounding the opening may be made of simple building materials or decorated with ornamentation. The elements of a portal can include the voussoir, tympanum, an ornamented mullion or trumeau between doors, and columns with carvings of saints in the westwork of a church.
