Many reptile groups first appeared during the Triassic period, possibly because so many niches were vacant at the time. Some of these new groups died out in the End–Triassic extinction event, but those that survived ruled the Earth for the rest of the Mesozoic. Examples include:
This was a major change, because in the middle Triassic period, the Synapsids (mammals' ancestors) were still dominant.
Many reptile groups became extinct during the Triassic, including:
Also, amongst the Synapsids (which used to be called mammal-like reptiles), the Dicynodonts died out during the end-Triassic extinction.
The Triassic was a period of great change in tetrapods: many new and important groups appeared, but many others became extinct. Of all the periods in the Mesozoic era, there are the least number of fossils from the Triassic period. This makes it difficult for scientists to explain these events.
Chromatic
A chromatic scale is a musical scale which uses every note as it goes up or down i.e. it goes up and down in semitones (half tones). To play a chromatic scale on the piano every note is played: both white and black notes (e.g. C, C sharp, D, D sharp, E, F etc.). A chromatic scale can start on any note.
The word “chromatic” comes from the Greek word “chromos” meaning “color”. Organists in the 16th and 17th centuries such as Sweelinck liked to write “Chromatic Fantasias”. These were pieces based on tunes which were chromatic. In those days, because of the tuning systems used, not all the semitones were exactly the same size. Going up a chromatic scale would have been like walking up a staircase with steps which were slightly larger or smaller in depth. This made chromatic scales very interesting and “colourful” which is why they were called “chromatic”.
Chromatic harmony means harmony (chords) which use notes which do not belong to the key the music is in (they are not in the key signature). Although Bach in the 18th century used chromatic harmony it was the 19th century composers who used it more and more. Wagner wrote music which was very chromatic: there were lots of sharps and flats and it kept modulating to different key areas. The chord at the beginning of his opera "Tristan and Isolde" is so famous that it is known as the "Tristan chord". It is very chromatic. The music is full of tension because it leaves us wondering which key the music is in.
Nelson Rockefeller
Nelson Aldrich Rockefeller (July 8, 1908 – January 26, 1979) was a liberal Republican American politician and businessman. He was from one of the richest and most powerful families in the United States.
His paternal grandfather was John D. Rockefeller Sr. His maternal grandfather was United States Senator Nelson Aldrich of Rhode Island. He was the son of John D. Rockefeller, Jr., and Abby Aldrich. He was Governor of New York from 1959 to 1973. He was the brother of David Rockefeller, chairman of Chase Bank, Winthrop, later Governor of Arkansas, John III, and Laurance. He is the uncle of former Senator John D. Rockefeller IV.
He was married twice. His first was to Mary Todhunter Clark until they divorced. His second was to Margaretta Fitler Murphy until his death from a heart attack.
He tried three times to gain his party's nomination for the United States presidency but lost to the slightly more conservative Vice President and future President Richard Nixon in 1960 and 1968 and conservative Senator Barry Goldwater of Arizona in 1964. He refused to support Goldwater in the general election after losing to him, which Nixon condemned him for and used to argue that Rockefeller was not a loyal Republican. He was Vice-President from 1974-1977 under Gerald Ford. He waged a campaign against future President George Bush to be appointed to that office. He won. He was a member of the Republican Party. He was in Knights of Pythias.

Special meanings are:
Pillar
A pillar is another word for a column, which is a vertical support structure in architecture.
Pillar may also mean:
Bier
A bier is a flat frame, traditionally wooden but sometimes made of other materials, used to carry a corpse for burial in a funeral procession. In antiquity it was often simply a wooden board on which the dead was placed covered with a shroud (cloth used for burial). In modern times, however, the corpse is almost never carried on the bier without being first placed in a coffin, though the coffin is sometimes kept open.
Coffin
A coffin (also known as a casket) is a box used to store dead bodies, either for burial or after cremation. Coffins used after cremation are what is known as an urn, where the ashes of the person are stored.
The word comes ultimately from Greek "kophinos", a basket. In English, the word was not used in a funeral sense until the 1500s.
Any box used to bury the dead in is a coffin.
The main distinction between a coffin and a casket is the shape. A casket regularly has 6 – 8 sides while coffins have a rectangular shape.
Many coffins are made out of materials such as wood, steel (which would have been used in Ancient Egyptian sarcophaguses), and many others. These types of coffins, for example wooden ones can have a rectangular or any other design, whereas a steel or any other metal used in making coffins (or sarcophaguses) could have the exact same but include religious marking added to make it look more appealing.
Agent Orange
Agent Orange is a very powerful herbicide that was used in the Vietnam War. It is a defoliant that destroys forests. It was used by the United States military so their enemies had no place to hide.
The problem with Agent Orange is that when it is released, some dioxins are also generated. Dioxins stay a long time in the environment. They are very toxic, and cause genetic modifications and cancer.
